Zinc finger protein 750 (ZNF750) has been identified as a potential tumor suppressor across multiple malignancies. Nevertheless, the specific involvement of ZNF750 in the regulation of mesenchymal cell differentiation and bone homeostasis has yet to be elucidated. In the current study, we observed a substantial presence of ZNF750 in bone tissue and noted alterations in its expression during osteogenic differentiation of mesenchymal progenitor cells. Functional experiments indicated that ZNF750 promoted osteogenic differentiation while impeding adipogenic differentiation from mesenchymal stem/progenitor cells. Further mechanistic investigations revealed that ZNF750 transcriptionally suppressed the expression of Snail family transcriptional repressor 1 (SNAI1) by binding to the proximal promoter region of Snai1 gene, thereby activating Wnt/β-catenin signaling. SNAI1 exerted opposing effects on cell differentiation towards osteoblasts and adipocytes in comparison to ZNF750. The overexpression of SNAI1 counteracted the dysregulated osteogenic and adipogenic differentiation induced by ZNF750. Furthermore, the transplantation of Znf750-silenced bone marrow stromal cells into the marrow of wild-type mice resulted in a reduction in cancellous and cortical bone mass, alongside a decrease in osteoblasts and an increase in marrow adipocytes, while the number of osteoclasts remained unchanged. This study presents the first demonstration that ZNF750 regulates the differentiation of osteoblasts and adipocytes from mesenchymal stem/progenitor cells by transcriptionally deactivating SNAI1 signaling, thereby contributing to the maintenance of bone homeostasis. It suggests that ZNF750 may represent a promising therapeutic target for metabolic bone disorders such as osteoporosis. Show less

Women diagnosed with PCOS exhibit a high prevalence of obstructive sleep apnea (OSA). This study aims to assess risk factors of OSA among patients with PCOS. This retrospective study included 126 patients with PCOS who were categorized into an OSA group (n = 30) and a non-OSA group (n = 96) according to the apnea-hypopnea index (AHI). A control group comprised 72 patients without PCOS who presented during the same period for infertility due to fallopian tube, pelvic, or male factors. Patients with PCOS A multivariate logistic regression model was used to analyze independent risk factors for OSA in the PCOS group. Patients with PCOS had significantly higher AHI values and elevated values for various physical indicators, including body mass index (BMI) and neck, waist, and hip circumferences; prolactin (PRL); fasting plasma glucose (FPG); insulin (FINS); triglycerides (TG); homeostasis model assessment of insulin resistance (HOMA-IR); 2-hour postprandial glucose (2-hPG) and insulin (2-hINS); AHI; and oxygen desaturation index (ODI). Conversely, levels of high-density lipoprotein cholesterol (HDL-C) and lowest oxygen saturation (LSaO OSA in PCOS patients is linked to metabolic indicators. High neck circumference and BMI levels were independent risk factors, highlighting the need for OSA in routine PCOS screening, particularly in the context of metabolic dysregulation. Show less

To identify gene alterations in circulating tumor DNA (ctDNA) from palbociclib-treated patients with advanced or metastatic breast cancer (ABC) in POLARIS to identify potential mutagenic drivers of resistance. POLARIS was a prospective, real-world study of palbociclib in patients with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) ABC in the United States and Canada. Patients who received ≥1 palbociclib dose and had ≥1 ctDNA measurement were included in the biomarker analysis. ctDNA samples were analyzed using the Guardant360 platform (73 genes) at baseline, cycle 2 day 1 (C2D1), and end of treatment (EOT). Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% CIs. A total of 344 patients were included in the biomarker analysis. Gene alterations were detected in 85% (286 of 336) of baseline samples, 72% (201 of 278) of C2D1 samples, and 85% (88 of 104) of EOT samples.

This study aims to identify oxidative stress-related genes (OSGs) in papillary thyroid carcinoma (PTC) and their common targets with resveratrol. Oxidative stress-related differentially expressed genes (OS-DEGs) were identified by intersecting datasets. The screened core genes were utilized to construct a prognostic model, and their prognostic value, along with their associations with clinical pathological characteristics and immune infiltration, was assessed. Subsequently, the core targets at the intersection of resveratrol and oxidative stress (OS) in PTC were screened, and their binding properties with resveratrol were analyzed. By conducting cross-database analysis, 38 OS-DEGs were identified, and 3 core genes APOE、CDKN2A、APOD were determined. The prognostic model based on core genes exhibited robust prognostic capabilities. The core genes displayed significant correlations with various clinical pathological parameters and a range of immune cells. Additionally, 13 targets of resveratrol for antioxidative stress were screened from databases. 6 high-performing targets, JUN, TGFB1, BCL2, CDKN1A, FOS, ICAM1, were revealed by topological analysis, all exhibiting binding energies lower than - 5.0 kcal/mol. Our study is the pioneering research to provide new insights into the diagnosis, prognosis, and treatment of PTC through the analysis of OSGs, presenting potential clinical implications. Furthermore, this research reveals the molecular functions associated with resveratrol and its pharmacological targets regulating OS in PTC for the first time. Show less

The prevailing treatment of Parkinson's disease (PD) is not yet satisfactory. The present investigate the neuroprotective effect of the GLP-1/GIP dual agonist tirzepatide and examine the potential mechanisms involved. Analysis of GLP1 receptor (GLP1R) and GIPR expression alterations in dopaminergic neurons from PD patients in the GSE238129 dataset. The MPTP-induced subacute PD mice was treated with tirzepatide, semaglutide and levodopa. Behavioral tests and brain histopathology of mice were evaluated. The transmission electron microscopy revealed the presence of ultrastructural alterations in the mitochondrial morphology. The ATP level was assessed in substantia nigra. Western blot and immunohistochemical staining were employed to quantify Drp1 and mitophagy proteins. Furthermore, Drp1 inhibitor and mitophagy activator were used to treat MPTP-induced subacute PD mice, and lysosome inhibitor chloroquine (CQ) and the autophagy inhibitor 3-methyladenine (3-MA) were used in SY5Y cells for validation. The gene expression levels of both GLP1R and GIPR were significantly downregulated in dopaminergic neurons derived from PD patients. Tirzepatide could significantly ameliorate MPTP-induced the loss of tyrosine hydroxylase (TH) protein in the substantia nigra. There was no statistically difference observed between one-third doses of tirzepatide when compared with semaglutide and levodopa. In addition, tirzepatide not only improved mitochondrial ultrastructure, but also enhanced mitochondrial ATP content. Tirzepatide was found to reduce Drp1 expression and reverse the expressions of mitophagy-related proteins, including Pink1, Parkin, and p62. There was no statistically difference observed between one-third doses of tirzepatide compared with semaglutide in mitochondrial energy control. In addition, we observed that MPTP-induced subacute PD mice treated with a Drp1 inhibitor and mitophagy activator exhibited therapeutic effects. In SY5Y cells, lysosomal and autophagy inhibitors significantly reduced mitochondrial membrane potential, ATP levels, and the NAD+/NADH ratio. This study demonstrates that the benefits of tirzepatide extend to mitochondrial networks, achieved by means of the inhibition of mitochondrial pathological fission, the promotion of mitophagy, in MPTP-induced subacute PD mice or cells model.

Precise differential diagnosis between lymphoplasmacytic lymphoma/Waldenström macroglobulinemia (LPL/WM) and marginal zone lymphoma (MZL) remains a challenging issue because of overlapping clinicopathological and immunophenotypic features. In the present study, the differential diagnostic potential of CD180 was assessed by determining its expression patterns in patients with MZL and LPL/WM through flow cytometry. The results indicated that LPL/WM cases exhibited a complete absence of CD180 expression on malignant B cells, whereas MZL cases showed robust CD180 expression (P < .001). Receiver operating characteristic analysis demonstrated that CD180 expression percentage showed optimal diagnostic accuracy in LPL/WM and MZL cases (area under the curve = 0.998, sensitivity = 100%, and specificity = 98.0%), with a further improvement in differentiation potential by the CD180 mean fluorescence intensity ratio (lymphocytes/monocytes) of ≤ 0.47 (area under the curve = 0.937).

Metabolic-associated fatty liver disease (MAFLD) is closely associated with insulin resistance (IR) and systemic inflammation. Apolipoprotein A1 (ApoA1) and Apolipoprotein B (ApoB), as notable non-traditional lipid markers, have demonstrated distinct advantages in identifying risks related to metabolic syndrome and coronary atherosclerosis, yet its association with MAFLD and the mediating roles of IR/inflammation remain unclear. This retrospective investigation involved 1061 participants, categorized into a non-MAFLD group ( The MAFLD group exhibited markedly elevated levels of neutrophils/lymphocytes, neutrophils/platelets, systemic immune inflammation index, systemic inflammation response index, pan-immune-inflammation value and triglyceride-glucose index (TyG), TyG body mass index (TyGBMI), and metabolic score for insulin resistance (METS-IR) compared to the non-MAFLD group. Logistic regression analysis revealed that ApoB/ApoA1, TyG, TyGBMI, and METS-IR were markedly linked to MAFLD risk. Spearman's correlation analysis identified substantial positive links between ApoB/ApoA1 and TyG ( Our findings clarify the complex interrelationships between ApoB/ApoA1, MAFLD risk, inflammation, and IR, and for the first time, demonstrate that IR may act as a key potential mediator in the link between ApoB/ApoA1 and MAFLD, rather than systemic inflammation. This suggests that IR may serve a more prominent role than chronic systemic inflammation in the association between lipid metabolism and MAFLD risk, and intervening in IR may be more effective than anti-inflammatory therapy in blocking the progression from lipid metabolism disorders to MAFLD.

In a phase II study, letrozole/abemaciclib demonstrated an objective response rate of 30% and a median progression-free survival (PFS) of 9.1 months in recurrent estrogen receptor-positive endometrial cancer (EC). While tissue-based tumor profiling revealed several mechanistically relevant candidate baseline genomic predictors of response, circulating tumor DNA (ctDNA) is a less invasive alternative to monitor therapeutic efficacy and define acquired resistance. Serial plasma specimens were obtained at baseline, C2D1, C3D1, C8D1, the time of objective response, and the time of progression. Samples were analyzed using the Guardant Reveal assay to assess methylation-based tumor fraction (TF), with the Guardant360 assay providing genotyping of >700 genes in samples with detectable ctDNA. Treatment response was assessed using a measure of the relative change in TF pre- versus on-treatment. A total of 99 of 102 (97%) samples from 28 patients were successfully analyzed. Patients with above median baseline TF exhibited worse median PFS (2.0 months Baseline and on-treatment ctDNA dynamics may provide an early indication of benefit from letrozole/abemaciclib in EC. ctDNA at the time of progression may identify resistance alterations that may inform subsequent therapy.

Pulmonary Hypertension (PH) is a significant contributor to cardiac mortality in Dilated Cardiomyopathy (DCM) patients. Inflammatory processes and oxidative stress play pivotal roles in the advancement of Pulmonary Hypertension (PH). The Monocyte-to-High-- Density-Lipoprotein Cholesterol Ratio (MHR), a newly identified biomarker indicative of inflammatory and oxidative stress, has not been extensively researched in the context of pulmonary hypertension, especially within the scope of dilated cardiomyopathy. Given the reason mentioned above, our research explores the correlation between the MHR and the severity of PH in patients suffering from DCM. In this study, we conducted a retrospective review of medical data from 107 individuals diagnosed with non-ischemic DCM, evaluating their clinical profiles, biochemical indicators, MHR, and echocardiographic parameters. We analyzed the relationships between Pulmonary Arterial Systolic Pressure (PASP) and the Ejection Fraction of the Left Ventricle (LVEF). Utilizing logistic regression analysis, we determined the predictors of PH. Findings indicated that the DCM-PH group exhibited a significantly larger male population and elevated New York Heart Association (NYHA) classification scores (both with p-values <0.001 and 0.01, respectively) compared to the DCM-only group. A positive association was observed between the PASP and parameters, such as the Dimensions of the Left Atrium (LAD) and Left Ventricle in Systole (LVDs), Monocyte (M) levels, Direct Bilirubin (DB), and MHR. Conversely, an inverse relationship was noted with serum lipid profiles, including Total Cholesterol (TC), HDL Cholesterol (HDL-c), and apolipoprotein A1. LVEF demonstrated positive linkage with the same lipid profiles and the Left Ventricular Posterior Wall Thickness (LVPWT) yet showed negative correlations with the NYHA classification, Red Blood Cell Distribution Width Standard Deviation (RDW-SD), Total Bilirubin (TB), Direct Bilirubin (DB), and dimensions of the left ventricle in diastole and systole, as well as MHR. Through logistic regression analysis, several factors were recognized as significant predictors for the severity of PH within the DCM cohort, with weight (OR1.20, CI 1.022-1.409, p=0.026), RDW-SD (OR1.988, CI 1.015-3.895, p=0.045), LVPW (OR3.577, CI 1.307-9.792, p=0.013), LVDd (OR1.333, CI 1.058-1.680, p=0.015), MHR (OR3.575, CI 1.502-8.506, p=0.032), and TB (OR1.416, CI 1.014-1.979, p=0.041) showing positive associations, while apoB (OR0.001 CI0.001-0.824, p=0.045) exhibiting negative associations, all with p-values <0.05. Higher MHR and LVD correlate with increased PASP and reduced LVEF in DCMPH patients. MHR and LVPW are independent predictors of PH severity, indicating their potential as novel severity markers in DCM-related PH. Show less

Tea polyphenols are a class of natural plant compounds with potent antioxidant properties, and their critical role in regulating lipid metabolism has been demonstrated in numerous studies. However, systematic research on the effects of tea polyphenols on lipid metabolism in lion-head geese remains limited. In this study, we examined the impact of tea polyphenols on lipid metabolism in geese through an integrative analysis of transcriptomics and metabolomics. A total of 240 healthy male lion-head geese with similar body weights at 1 day of age were randomly allocated into two treatment groups (6 replicates per group, with 20 geese per replicate). The control group received a basal diet, while the experimental group was supplemented with 1000 mg/kg of tea polyphenols (50.4 % catechin purity) in the basal diet for 18 weeks. The results indicated that serum total antioxidant capacity (T-AOC) and glutathione peroxidase (GSH-Px) activities were significantly increased (P < 0.05), while malondialdehyde (MDA) levels were significantly decreased (P < 0.05) in the tea polyphenol group compared to the control group. Additionally, serum triglycerides (TG), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) activities were significantly lower (P < 0.05) in the tea polyphenol group than in the control group. Hepatic transcriptomic analysis further revealed that tea polyphenols significantly modulated the expression of several genes involved in lipid metabolism, including angiopoietin-like 4 (ANGPTL4), which plays a role in regulating lipid homeostasis, as well as glycerophosphodiester phosphodiesterase domain containing 2 (GDPD2), immunoglobulin heavy chain (IGH), proto-oncogene protein c-fos (FOS), and matrix metallopeptidase 1 (MMP1), etc. Serum metabolomic analysis also demonstrated significant alterations in lipid metabolites induced by tea polyphenols, including the downregulation of fatty acyl metabolites such as L-Palmitoylcarnitine and Hexadecanal. Moreover, the combined analysis revealed a strong positive correlation between ANGPTL4 and the organic compounds of steroidal saponins, such as Glucoconvallasaponin B, and negative correlations with glycerophospholipid metabolites, such as LysoPC (P-16:0). The comprehensive analysis suggests that the inclusion of tea polyphenols in the diet enhances the antioxidant capacity of lion-head geese, improves hepatic lipid profiles, and regulates lipid metabolism via modulating lipid metabolism-related genes and metabolites.

The lipid ratios, which include non-high-density lipoprotein cholesterol (non-HDL-C)/high-density lipoprotein cholesterol (HDL-C), remnant cholesterol (RC)/HDL-C, apolipoprotein B (ApoB)/apolipoprotein A1 (ApoA1), low-density lipoprotein cholesterol (LDL-C)/HDL-C, ApoB/HDL-C, total cholesterol (TC)/HDL-C, triglycerides (TG)/HDL-C, were included and analyzed. Sex differences in the relationship between lipid ratios and carotid plaque were discussed. The risk of carotid plaque was found to be significantly associated with the Non-HDL-C /HDL-C, RC/HDL-C, ApoB/ApoA1, LDL-C /HDL-C, ApoB/HDL-C, TC/HDL-C in females but not in males. The ApoB/HDL risk presented the highest relationship with carotid plaque in females only. The predictive value of the aforementioned lipid ratios for carotid plaque was observed in females only.

To explore the stratification and identification of adrenal lipid-poor adenomas (LPAs), adrenal cysts (ACs), and adrenal ganglioneuromas (AGNs) from each other using contrast-enhanced computed tomography (CT). Pathologically confirmed, 348 patients were categorized into Model 1 (260 LPAs, 34 ACs), Model 2 (260 LPAs, 54 AGNs), and Model 3 (34 ACs, 54 AGNs). Statistical analyses were performed on the differences in the degree of enhancement in the arterial/venous phase (DEap/DEvp) (in HU) and the corresponding graded variables for the arterial/venous phase (GVap/GVvp). Models were evaluated via receiver operating characteristic (ROC) curves, calibration curves, and the Hosmer‒Lemeshow (HL) test. The values of the area under the curve (AUC) for DEap, DEvp, GVap, and GVvp in Models 1-3 were 0.996, 1.000, 0.993, and 0.999; 0.980, 0.978, 0.961, and 0.975; and 0.734, 0.892, 0.725, and 0.883, respectively. The p values of the HL test were 0.984, 1.000, and 0.113, respectively. The DEvp interval values (in HU) for the LPAs, ACs, and AGNs were [4.9, 190.2] HU, [-3.7, 4.2] HU, and [-4.8, 41.8] HU, respectively. The GVap and GVvp ranges for the LPAs, ACs, and AGNs were [1, 6], [0, 2], and [0, 2] and [1, 6], [0, 1], and [0, 5], respectively. DEvp enhanced discrimination in Models 1 and 3, whereas DEap performed better in Model 2. Lesions with DEvp < 4.5 HU are likely represent non-enhancing pathology (e.g., cysts). When both GVap and GVvp are 0, when both GVap and GVvp are [2, 6], and when GVap is [3, 6] and GVvp is 6, LPA, AC, and AGN are excluded. Not applicable. Show less

Skeletal muscle is the largest tissue in mammals, and it plays a crucial role in metabolism and homeostasis. Skeletal muscle development and regeneration consist of a series of carefully regulated changes in gene expression. Leiomodin2 (LMOD2) gene is specifically expressed in the heart and skeletal muscle. But the physiological functions and mechanisms of LMOD2 on skeletal muscle development are unknown. In this study, we examined the expression levels of the LMOD2 in porcine tissues and C2C12 cells. LMOD2 is mainly expressed in the heart, followed by skeletal muscle. The expression level of LMOD2 gradually decreased with skeletal muscle growth, but increased after injury. LMOD2 expression levels increased gradually with C2C12 cells proliferation and differentiation. In terms of function, the muscle fiber types were altered after LMOD2 was knocked out in C2C12 cells, MyHC-I and MyHC-2b were inhibited, whereas MyHC-2a and MyHC-2x were promoted. LMOD2 knockout has different effects on LMOD family, LMOD1 expression level was promoted, while LMOD3 was inhibited. Loss of LMOD2 suppressed cell viability and PAX7 protein expression. At the transcriptome level, proliferation-related genes and muscle contraction-related genes were respectively inhibited after LMOD2 knockout. In terms of molecular networks, a series of experiments have shown that MyoG is a transcription factor for LMOD2, while miR-335-3p can negatively regulate LMOD2 expression. We screened ACTC1 as a candidate interacting protein for LMOD2 using protein prediction software and RNA-seq, and Co-IP experiments confirmed the relationship between LMOD2 and ACTC1. In vivo, Lentivirus-mediated LMOD2 knockdown reduces muscle mass. LMOD2 knockdown inhibited MyHC-I mRNA expression, but had no effect on MyHC-2b. The protein expression of MyHC-I, MyHC-2x, and MyHC-2b was suppressed after LMOD2 knockdown. Collectively, our data indicates that LMOD2 knockout inhibits myoblast proliferation and alters muscle fiber types. MyoG is a transcription factor for LMOD2, while miR-335-3p can negatively regulate LMOD2 expression. Moreover, LMOD2 and ACTC1 interact to regulate myogenic differentiation. Our study provides a new target for skeletal muscle development. Show less

The quality of eggshells holds substantial economic significance and serves as a critical selection criterion in poultry breeding. Eggshell translucency significantly impairs their aesthetic quality, which is structurally attributed to the thinning of the eggshell membrane or reduced tensile strength. In this study, 836 dwarf white hens were selected, with 45 hens each assigned to the opaque group and the translucent group. Grading for eggshell translucency was conducted at 75, 80, and 85 weeks of age. Based on the results from these three gradings, 35 hens that consistently produced translucent eggs and 35 hens that consistently produced opaque eggs were reclassified into the translucent group and the opaque group, respectively. The thickness of the eggshell membrane, latitudinal and longitudinal tensile force and length, and other indicators related to eggshell membrane quality were measured. Correlation analysis was performed using RNA-seq genomics and DIA proteomics based on the relationships among these indicators. Transcriptome analysis revealed 179 significantly differentially expressed genes, indicating that the causes of translucent eggshells are associated with metabolism, signal transduction, the immune system, molecular binding, transport, and catabolism.

Evidence of the benefits of cordycepin (Cpn) for treating obesity is accumulating, but detailed knowledge of its therapeutic targets and mechanisms remains limited. This study aimed to systematically identify Cpn's therapeutic targets and pathways in Western diet (WD)-induced obesity using integrated network pharmacology, transcriptomics, and experimental validation. A Western diet (WD)-induced mice model was used to evaluate the effectiveness of Cpn in ameliorating obesity. A network pharmacology analysis was then employed to identify the potential anti-obesity targets of Cpn. GO functional enrichment and KEGG pathway analysis were performed to elucidate the potential functions of the identified targets, followed by constructing a protein-protein interaction network to screen the core targets. Meanwhile, quantitative transcriptomics was conducted to validate and broaden the network pharmacology findings. Finally, molecular docking and quantitative real-time PCR assay were used for the core target validation. Cpn treatment effectively alleviated obesity-related symptoms in WD-induced mice. The metabolic pathway, insulin signaling pathway, HIF-1 signaling pathway, FoxO signaling pathway, lipid and atherosclerosis pathway, and core targets including CPS1, HRAS, MAPK14, PAH, ALDOB, AKT1, GSK3B, HSP90AA1, BHMT2, EGFR, CASP3, MAT1A, APOM, APOA2, APOC3, and APOA1 are involved in regulating the therapeutic effect of Cpn. This study comprehensively uncovers the potential mechanism of Cpn against obesity based on network pharmacology and quantitative transcriptomics, which provides evidence for revealing the pathogenesis of obesity, suggesting that Cpn is a possible lead compound for anti-obesity treatment.

Heart failure with preserved ejection fraction (HFpEF) has become the most prevalent type of heart failure, but effective treatments are lacking. Cardiac lymphatics play a crucial role in maintaining heart health by draining fluids and immune cells. However, their involvement in HFpEF remains largely unexplored. We examined cardiac lymphatic alterations in mice with HFpEF with comorbid obesity and hypertension, and in heart tissues from patients with HFpEF. Using genetically engineered mouse models and various cellular and molecular techniques, we investigated the role of cardiac lymphatics in HFpEF and the underlying mechanisms. In mice with HFpEF, cardiac lymphatics displayed substantial structural and functional anomalies, including decreased lymphatic endothelial cell (LEC) density, vessel fragmentation, reduced branch connections, and impaired capacity to drain fluids and immune cells. LEC numbers and marker expression levels were also decreased in heart tissues from patients with HFpEF. Stimulating lymphangiogenesis with an adeno-associated virus expressing an engineered variant of vascular endothelial growth factor C (VEGFC Our study provides evidence that cardiac lymphatic disruption, driven by impaired BCAA catabolism in LECs, is a key factor contributing to HFpEF. These findings unravel the crucial role of BCAA catabolism in modulating lymphatic biology, and suggest that preserving cardiac lymphatic integrity may present a novel therapeutic strategy for HFpEF.

Diabetic kidney disease (DKD) is a common and serious complication of diabetes, affecting approximately 40% of patients with the condition. The pathogenesis of DKD is complex, involving multiple processes such as metabolism, inflammation, and fibrosis. Given its increasing incidence and associated mortality, there is an urgent need to identify novel pathogenic genes and therapeutic targets. This study systematically identified hub DKD-associated genes and their potential molecular mechanisms through bioinformatic analysis. Gene expression datasets from DKD patients and healthy controls were obtained from the GEO database. Hub genes were screened using differential expression analysis, weighted gene co-expression network analysis (WGCNA), LASSO regression, random forest (RF) algorithms, and consensus clustering for DKD patient classification. Additionally, immune cell infiltration analysis was performed on differentially expressed genes to explore the relationship between hub genes and the immune microenvironment. Potential drugs targeting LPL were predicted based on gene-drug interaction analysis. Immunohistochemistry was used to verify the expression of LPL and TNF-α in kidney tissues from patients with varying degrees of DKD severity, as well as their relationship with kidney function impairment. This study revealed that LPL, a lipoprotein metabolism gene, plays a crucial role in DKD, participating in cholesterol and glycerolipid metabolism as well as PPAR signaling. LPL expression was negatively correlated with pro-inflammatory M1 macrophages and various subsets of T cells, including naïve CD4 T cells and gamma delta T cells, while positively correlated with follicular helper T cells, suggesting its immune-regulation effects in DKD progression. Potential LPL-targeting drugs, such as Ibrolipim, anabolic steroid, and acarbose, might mitigate DKD. LPL expression was decreased with DKD severity and was correlated with TNF-α and kidney dysfunction markers, indicating its key role in DKD progression. LPL is a pivotal regulator of lipid metabolism and immune inflammation in DKD. Potential drugs targeting LPL offer new candidates for precision treatment of DKD. These findings lay a theoretical foundation for understanding the molecular mechanisms of DKD and developing LPL-based therapeutic strategies. Show less

The significance of apoptosis-related genes (ARGs) in the prognosis of bladder cancer (BLCA) has gradually emerged. Therefore, this study aims to investigate the prognostic significance and pathogenesis of PDT related genes (PDTRGs)-ARGs in BLCA cases. Based on the BLCA data in TCGA, PDTRGs-ARGs with prognostic value in BLCA patients were screened. Subsequently, the prognostic value and diagnostic performance of all candidate genes were evaluated by univariate Cox regression analysis and ROC curves. Then, GSEA, GSVA and immune microenvironment analysis were conducted based on candidate genes. Finally, the molecular mechanisms of key candidate genes in BLCA patients were initially explored by qRT-PCR, CCK-8 analysis, Transwell Assay and Western Blotting. A total of 5 ARGs-PDTRGs (EMP1, FGFR1, PLPPR4, JUN, TNFRSF25) were screened as prognostic biomarkers for BLCA. Survival analysis revealed significant differences in overall survival of the five prognostic biomarkers in the high/low expression groups. ROC curve analysis revealed that the five prognostic biomarkers had strong prognostic predictive ability. QRT-PCR proved that the expression of EMP1, FGFR1, PLPPR4 and JUN was obviously reduced, while TNFRSF25 was markedly increased in BLCA tissue samples and cell lines. The following research confirmed that FGFR1 inhibited the biological process of T24 cells by activating cGMP-PKG pathway. Five ARGs-PDTRGs (EMP1, FGFR1, PLPPR4, JUN, TNFRSF25) were screened as prognostic biomarkers for BLCA. Among them, FGFR1 inhibits the biological process of T24 cells via activating cGMP-PKG pathway.

The uptake of modified lipoproteins by macrophages to form foam cells is a crucial step in atherosclerosis (AS) development. N7-methylguanosine (m7G) is frequently methylated internally in eukaryotic RNA transcripts and plays a crucial role in various processes. This study aimed to investigate the m7G RNA methylation profile in AS. We employed high-throughput sequencing to analyze the m7G methylome in foam cells induced by ox-LDL, using an in vitro AS model. Then, m7G-seq, RNA-seq, bioinformatic analysis, cell biological analyses, followed by qRT-PCR were performed. Additionally, the roles of SCARB2 and RASSF8 were investigated in an in vivo AS mouse model, and cells with SCARB2/RASSF8 overexpression/knockdown. In vitro and in vivo oil red O staining confirmed the successful establishment of the atherosclerotic foam cell and mouse models. We identified 1197 m7G peaks and 430 differentially expressed mRNAs during foam cell formation. Bioinformatics analyses revealed different m7G peaks associated with the gonadotropin-releasing hormone (GnRH) signaling pathway, cytoskeleton-dependent intracellular transport, and mitochondrial organization, regulating the processes of macrophage foaminess. Moreover, 28 key differentially expressed methylated genes were identified. m7G methyltransferases (WDR4, METTL1, WBSCR22) were upregulated in the AS cell model, and m7G modification genes (SCARB2 and RASSF8) associated with pathological processes were confirmed. Immunofluorescence staining showed that RASSF8 and SCARB2 were both expressed in AS mice plaque tissues. Finally, RASSF8/SCARB2 overexpression could promote apoptosis and lipid accumulation of ox-LDL-induced RAW264.7 cells. An m7G transcriptome-wide map of AS in vitro was created, and the differentially m7G methylated genes SCARB2 and RASSF8 may be crucial in macrophage foaminess. Our findings offer novel insights into the underlying mechanisms and potential treatments for AS. Show less

Family caregivers ('carers') bear the highest care burden during the postoperative survivorship period of pancreatic cancer, given its poor prognosis. Most carers report unmet needs when taking on caregiving responsibilities during this period. Thoroughly investigating carers' needs is essential for helping families address practical care challenges. However, this important topic remains underexplored. To assess the need levels and identify need subgroups among carers of patients with pancreatic cancer 6 months after surgery and demographic predictors contributing to heterogeneity. Cross-sectional study. Participants were recruited from the pancreas centres of four tertiary A-level comprehensive hospitals in Jiangsu Province, China. 240 patients with pancreatic cancer and their carers ('dyads') participated in the survey. Carers completed the Comprehensive Needs Assessment Tool in Cancer for Carers, the Activities of Daily Living Scale for patients, and the General Demographic Information Questionnaire for dyads. Latent profile analysis (LPA) was used to categorise carers' needs. Non-parametric and chi-square tests were used to examine differences in need scores and sociodemographic characteristics among subgroups. Multiple logistic regression (MLR) was used to analyse sociodemographic impacts. Six months post-surgery, the total carers' need score was 41.83 ± 22.65 points, indicating a moderate level, with the highest needs reported for healthcare personnel, information and knowledge, and facilities and services. The LPA results revealed that carers were divided into five distinct subgroups based on differing levels of need across the domains assessed by the Comprehensive Needs Assessment Tool in Cancer for Carers, with proportions of 8.8 %, 22.5 %, 8.3 %, 55 %, and 5.4 %. Subgroup membership was predicted by four factors: carers' sex (odds ratio [OR]: 11.08, 95 % confidence interval [CI]: 1.64, 74.99, We have highlighted the complex individualised needs of carers of patients with pancreatic cancer. Through LPA and MLR, we identified distinct need subgroups and their predictors. Healthcare professionals may be able to improve dyads' health by tailoring support to each subgroup's specific needs and issues.

Calcific aortic stenosis (CAS) is frequently accompanied by systemic comorbidities, but their causal relationships and shared genetic architecture remain poorly defined. We aimed to map the multisystem comorbidity network of CAS and clarify underlying genetic mechanisms. In 467 484 participants from the UK Biobank, observational and polygenic phenome-wide association studies evaluated associations between CAS and 1571 phenotypes, integrating disease-trajectory analyses to visualise temporal patterns. Associations replicated across observational and polygenic analyses were tested using two-sample Mendelian randomisation (MR) based on 22 CAS-related variants from FinnGen. Polygenic risk score (PRS) analyses excluding specific genes assessed their contributions, particularly LPA and plasma lipoprotein(a) (Lp(a)) levels. CAS was associated with higher risks of 42 cardiovascular and non-cardiovascular conditions, most prominently metabolic, endocrine, haematological and respiratory disorders. Temporal analyses showed that circulatory and metabolic diseases typically precede other comorbidities in CAS trajectories. MR findings were consistent with causal effects of CAS on multiple cardiovascular diseases, iron-deficiency anaemia, mental disorders and pleural effusion. When LPA variants were removed from the CAS PRS or plasma Lp(a) concentration was adjusted for, most associations lost significance, indicating a shared LPA/Lp(a)-mediated genetic pathway. CAS is embedded within a broad multisystem comorbidity network, driven largely by genetic variation at LPA and elevated Lp(a). These findings highlight pleiotropic mechanisms linking valvular calcification with systemic disease and support LPA-targeted therapies as a promising avenue for reducing the multisystem burden of CAS.

Phosgene, used in large-scale industrial production, is highly toxic and irritant. Accidental exposure can lead to varying degrees of injuries, with severe cases potentially resulting in acute lung injury or acute respiratory distress syndrome, resulting in a mortality rate of 40%-50%. The indirect damages of phosgene (inflammation and oxidative stress) are considered important factors in phosgene-induced acute lung injury (P-ALI). The expression of Liver X Receptor α (LXRα) significantly reduces during periods of inflammation. LXRs were initially discovered to be highly expressed in the liver, whereas LXRs are expressed in immune cells and vascular endothelial cells, playing a significant role in anti-inflammatory and antioxidant responses. LXRα may have pulmonary protection in P-ALI. However, evidence to verify this association is still lacking. In this study, rats were divided into six groups to explore the potential role of LXRα in P-ALI. This study found that GW3965 effectively activated LXRα, upregulated its expression and downregulated the levels of proinflammatory cytokines, inhibited malondialdehyde activity while enhancing superoxide dismutase activity, suppressed apoptosis and ameliorated the pathological processes of P-ALI, ultimately exerting pulmonary protection in P-ALI. Further validation revealed that the pulmonary protective effect of LXRα may be associated with the PI3K/Akt and NF-kB signalling pathways. Show less

This study explored latent mental health profiles among adolescents in southwestern China and the association with emotional regulation using the dual-factor model framework. 1,682 junior middle school students completed the LPA revealed three profiles: Troubled (31.51%, high negative symptoms/low well-being), complete mental health (61.30%, low negative symptoms/high well-being), and more troubled (7.19%, severe negative symptoms/extremely low well-being). Cognitive reappraisal positively predicted complete mental health (vs. Troubled; Three distinct profiles emerged, differing from the traditional dual-factor model. Cognitive reappraisal protects mental health, while expressive suppression correlates with poorer outcomes, highlighting the need for targeted interventions promoting cognitive reappraisal. Show less
