The chimeric cytokine IC7Fc conveys the metabolic signaling properties of the glycoprotein 130 receptor cytokines interleukin-6 and ciliary neurotrophic factor via membrane-bound signaling. IC7Fc was previously shown to slow the progression of type 2 diabetes mellitus, and here, we demonstrate its effect on atherosclerotic development. In APOE*3-Leiden.CETP mice, an atherosclerosis-prone model with a humanized lipoprotein metabolism, IC7Fc markedly lowered plasma triglyceride and total cholesterol levels. This was mechanistically explained by an inhibition of de novo lipogenesis in the liver, increased synthesis of bile acids from cholesterol, and down-regulated apolipoprotein B synthesis, which resulted in decreased cholesterol secretion in very low-density lipoprotein particles. As a consequence, IC7Fc treatment considerably reduced atherosclerotic lesion formation and vascular inflammation compared with current antihyperlipidemic therapy. In conclusion, IC7Fc is a promising pharmacological treatment for cardiometabolic diseases targeting hyperlipidemia and inflammation. Show less

Mammalian scent glands mediate species-specific chemical communication, yet the mechanistic basis for convergent musk production remain incompletely understood. Forest musk deer and muskrat have independently evolved specialized musk-secreting glands, representing a striking case of convergent evolution. Through an integrated multi-omics approach, this study identified cyclopentadecanone as a shared key metabolic precursor in musk from both forest musk deer and muskrat, although downstream metabolite profiles diverged between the two lineages. Single-cell RNA sequencing revealed that these specialized apocrine glands possessed unique secretory architecture and exhibited transcriptional profiles associated with periodic musk production, distinct from those in conventional apocrine glands. Convergent features were evident at the cellular level, where acinar, ductal, and basal epithelial subtypes showed parallel molecular signatures across both taxa. Notably, acinar cells in both species expressed common genes involved in fatty acid and glycerolipid metabolism (e.g., Show less

Evidence has linked self-reported sedentary behaviors with dementia and cognitive impairment; however, the underlying mechanisms remain poorly understood. We investigated the associations of accelerometer-measured sedentary behavior patterns with gray matter atrophy patterns in rural-dwelling older adults, while taking into account the manner in which sedentary time is accrued (in short or long bouts). This community-based study involved 911 dementia-free older adults (age ≥ 60 years, 59% women) who participated in both ActiGraph and brain MRI substudies within MIND-China (2018-2020). Sedentary behavior parameters (total sedentary time, mean sedentary bout duration, and sedentary breaks) were recorded with accelerometers. Regional gray matter volumes (GMV) were measured using voxel-based morphometry (VBM) methods. Data were analyzed using the general linear regression models, restricted cubic spline curves, and VBM analysis. There was an inverted U-shaped association between daily sedentary time and GMV in temporal, cingulate, and medial temporal cortex, while longer mean sedentary bout duration was linearly related to decreased GMV in total, frontal, temporal, insula, cingulate, and medial temporal cortex. Greater daily time spent in light or moderate-to-vigorous physical activity (LPA and MVPA) was correlated with larger insula GMV. The VBM analysis suggested that prolonged daily total sedentary time and mean sedentary bout duration were significantly associated with smaller GMV in extensive brain regions, especially in thalamus and insula. In conclusion, gray matter atrophy associated with sedentary behavior in older adults is characterized by reduced GMV in global, frontal, temporal, medial temporal, and cingulate cortex, especially in the insula and thalamus regions.

Conjugated linoleic acid (CLA) isomers have been reported to reduce body weight and promote glycolipid metabolism in animals. In a preliminary study, we revealed that trans-10, cis-12-CLA (10,12-CLA) plays an important role in modulating lipid metabolism in chickens. However, the underlying mechanism remains unclear. In this study, we constructed an isolated in vitro model with primary chicken hepatocytes to investigate the effect of 10,12-CLA on lipid metabolism. 10,12-CLA inhibited lipid accumulation by decreasing the mRNA expression of sterol regulatory element-binding protein-1c (SREBP-1c), SREBP2, 3‑hydroxy-3-methylglutaryl-CoA reductase (HMGCR), fatty acid synthase (FAS), adipose triacylglyceride lipase (ACC), and lipoprotein lipase (LPL) and increasing the mRNA expression of peroxisome proliferator-activated receptor α (PPARα), carnitine palmitoyltransferase 1 (CPT1) and adipose triacylglyceride lipase (ATGL). Furthermore, 10,12-CLA treatment activated the protein expression of extracellular signal-regulated kinase 1/2 (ERK1/2) and AMP-activated protein kinase (AMPK), whereas treatment with the ERK1/2 inhibitor U0126 reversed the inhibitory effects of 10,12-CLA on lipid accumulation by blocking the ERK1/2-AMPK pathway, leading to increased lipid accumulation and triglyceride content in primary chicken hepatocytes. These findings suggest that in chicken hepatocytes, 10,12-CLA alleviates hepatocyte lipid deposition by activating the ERK1/2-AMPK pathway, promoting fatty acid oxidation and reducing lipid synthesis, revealing the potential mechanism through which 10,12-CLA regulates hepatic lipid metabolism in chickens.

Goose foie gras production requires force-feeding with high-energy feed, disrupting hepatic lipid homeostasis and causing excessive lipid accumulation. To investigate the formation mechanism, we collected liver samples from Landes geese at pre-force-feeding (D0), mid-force-feeding (D16), and terminal-force-feeding (D25) stages. Overfeeding shifted liver color from reddish-brown to yellow, significantly increasing size and weight. Histological analysis revealed pronounced lipid droplet accumulation in hepatocytes. Biochemical analysis indicated force-feeding groups (D16, D25) exhibited continuous and significant decreases in liver moisture, crude ash, and crude protein content compared to D0, while crude fat increased substantially. Integrated transcriptomic and lipidomic analyses identified 497 differentially expressed genes (DEGs) and 368 differential lipid molecules (DLMs) between D16 and D0, and 303 DEGs and 172 DLMs between D25 and D16. KEGG enrichment highlighted four pathways associated with fatty liver formation: glycerolipid metabolism, adipocytokine signaling pathway, ErbB signaling pathway, and MAPK signaling pathway. Within these, key genes ( Show less

Brain metastasis occurs in up to 40% of patients with non-small cell lung cancer (NSCLC). Considerable genomic heterogeneity exists between the primary lung tumor and respective brain metastasis; however, the identity of the genes capable of driving brain metastasis is incompletely understood. Here, we carried out an in vivo genome-wide CRISPR activation screen to identify molecular drivers of brain metastasis from an orthotopic xenograft model derived from a patient with NSCLC. We found that activating expression of the Alzheimer's disease-associated beta-secretase 1 (BACE1) led to a substantial increase in brain metastases. Furthermore, genetic and pharmacological inhibition of BACE1 blocked NSCLC brain metastasis. Mechanistically, we identified that BACE1 acts through epidermal growth factor receptor to drive this metastatic phenotype. Together, our data highlight the power of in vivo CRISPR activation screening to unveil molecular drivers and potential therapeutic targets of NSCLC brain metastasis. Show less

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) poses a substantial global threat. SARS-CoV-2 nonstructural proteins (NSPs) are essential for impeding the host replication mechanism while also assisting in the production and organization of new viral components. However, NSPs are not incorporated into viral particles, and their subsequent fate within host cells remains poorly understood. Additionally, their role in viral pathogenesis requires further investigation. This study aimed to discover the ultimate fate of NSP6 in host cells and to elucidate its role in viral pathogenesis. We investigated the effects of NSP6 on cell death and explored the underlying mechanism; moreover, we examined the degradation mechanism of NSP6 in human cells, along with analysing its correlation with coronavirus disease 2019 (COVID-19) severity in patient peripheral blood mononuclear cells (PBMCs). NSP6 was demonstrated to induce cell death. Specifically, NSP6 interacted with EI24 autophagy-associated transmembrane protein (EI24) to increase intracellular Ca This study reveals that KLHL22-mediated ubiquitination controls NSP6 stability and that NSP6 induces autophagic cell death via calcium overload, highlighting its cytotoxic role and suggesting therapeutic strategies that target calcium signaling or promote NSP6 degradation as potential interventions against COVID-19.

Stroke is a life‑threatening cerebrovascular disorder categorized into two major subtypes: Ischemic and hemorrhagic. Characterized by high morbidity and mortality rates, its clinical management remains challenging due to limited therapeutic options. Interleukin (IL)‑27, a pleiotropic cytokine with demonstrated neuroprotective potential, has emerged as a promising candidate for stroke intervention. IL‑27 exerts immunomodulatory effects within the central nervous system, including suppression of proinflammatory T‑cell proliferation and induction of regulatory T‑cell differentiation. These mechanisms collectively attenuate neuroinflammation, mitigate neuronal apoptosis and prevent neurodegenerative processes. The efficacy of IL‑27 in reducing cerebral damage in both ischemic and hemorrhagic stroke models has been validated, although clinical translation remains to be achieved. The present review summarizes: i) The epidemiology of stroke; ii) the immunoregulatory functions of IL‑27 and its neuroprotective mechanisms across stroke subtypes; iii) innovative brain‑targeted delivery approaches; iv) IL‑27 clinical applicability with supporting evidence; and v) possible risks and solutions in clinical applications. By collating the current knowledge, the present study provides a translational framework for advancing IL‑27‑based therapies in stroke management. Show less

Studying the molecular properties of drugs and their interactions with human targets aids in better understanding the clinical performance of drugs and guides drug development. In computer-aided drug discovery, it is crucial to utilize effective molecular feature representations for predicting molecular properties and designing ligands with high binding affinity to targets. However, designing an effective multi-task and self-supervised strategy remains a significant challenge for the pretraining framework. In this study, a multi-task self-supervised deep learning framework is proposed, MTSSMol, which utilizes ≈10 million unlabeled drug-like molecules for pretraining to identify potential inhibitors of fibroblast growth factor receptor 1 (FGFR1). During the pretraining of MTSSMol, molecular representations are learned through a graph neural networks (GNNs) encoder. A multi-task self-supervised pretraining strategy is proposed to fully capture the structural and chemical knowledge of molecules. Extensive computational tests on 27 datasets demonstrate that MTSSMol exhibits exceptional performance in predicting molecular properties across different domains. Moreover, MTSSMol's capability is validated to identify potential inhibitors of FGFR1 through molecular docking using RoseTTAFold All-Atom (RFAA) and molecular dynamics simulations. Overall, MTSSMol provides an effective algorithmic framework for enhancing molecular representation learning and identifying potential drug candidates, offering a valuable tool to accelerate drug discovery processes.

Mitophagy plays a critical role in maintaining mitochondrial quality and cellular homeostasis. But the specific contribution of mitophagy-related E3 ubiquitin ligases to prognoses remains largely unexplored. In this study, we identified a novel mitophagy-related E3 ubiquitin ligase prognostic signature using least absolute shrinkage and selector operator (LASSO) and multivariate Cox regression analyses in breast cancer. Based on median risk scores, patients were divided into high-risk and low-risk groups. Functional enrichment analyses were conducted to explore the biological differences between the two groups. Immune infiltration, drug sensitivity, and mitochondrial-related phenotypes were also analyzed to evaluate the clinical implications of the model. A four-gene signature (ARIH1, SIAH2, UBR5, and WWP2) was identified, and Kaplan-Meier analysis demonstrated that the high-risk group had significantly worse overall survival (OS). The high-risk patients exhibited disrupted mitochondrial metabolism and immune dysregulation with upregulated immune checkpoint molecules. Additionally, the high-risk group exhibited higher sensitivity to several drugs targeting the Akt/PI3K/mTORC1 signaling axis. Accompanying mitochondrial metabolic dysregulation, mtDNA stress was elevated, contributing to activation of the senescence-associated secretory phenotype (SASP) in the high-risk group. In conclusion, the identified signature provides a robust tool for risk stratification and offers insights into the interplay between mitophagy, immune modulation, and therapeutic responses for breast cancer.

End-stage renal disease (ESRD) is associated with high morbidity and mortality. Identifying patients with stage 4 chronic kidney disease (CKD) at risk of short-term progression to ESRD remains challenging. Accurate prediction can improve advanced care planning and patient outcomes. This study aimed to develop and validate a machine learning (ML) model for predicting progression within 25 weeks (approximately six months) of ESRD in patients with stage 4 CKD. Electronic health records (EHRs) of patients with stage 4 CKD were analyzed. Nine ML models including Ridge regression (Ridge), random forest (RF), and eXtreme Gradient Boosting (XGBoost) were used to predict short-term progression to ESRD within 25 weeks. The models were trained and externally validated using the data of 346 and 105 patients. Of the 451 patients with stage 4 CKD, 219 developed ESRD. Among the evaluated models, XGBoost demonstrated the best overall performance. In the internal validation, it achieved an area under the curve (AUC) of 0.93, an accuracy of 0.90, and an F1 score of 0.89. In the external validation, XGBoost maintained the highest AUC (0.85), accuracy (0.79), and F1 score (0.79), along with the highest average precision (0.89) and a low log-loss (0.48), indicating strong discriminative ability and good generalizability. The top predictive features included high-density lipoprotein cholesterol, Alb, Cys C, ApoB, FGB, Bun, Neutrophil, and Total cholesterol. This study demonstrated the feasibility of ML for assessing ESRD prognosis based on easily accessible clinical features. XGBoost demonstrated superior performance in both internal and external validation, suggesting its potential for future patient screening. Show less

Fibroblast growth factor receptors (FGFRs) are well-established oncology targets, with aberrant FGFR2 and FGFR3 activation implicated in multiple tumor types, including cholangiocarcinoma and urothelial carcinoma. Currently approved FGFR2/3-targeted therapies rely on pan-FGFR small-molecule kinase inhibitors, which often lead to off-target toxicities due to unintended inhibition of FGFR1 and FGFR4, as well as acquired resistance driven by gatekeeper mutations. Herein, we report the discovery of INCB126503, a highly potent, orally bioavailable FGFR2/3 inhibitor with excellent isoform selectivity and equipotent activity against gatekeeper mutants. INCB126503 effectively suppresses FGFR signaling in vivo without inducing hyperphosphatemia and demonstrates significant antitumor efficacy in xenograft models harboring FGFR3 genetic alterations.

Time-restricted feeding (TRF) is a dietary intervention that has been shown to have numerous health benefits. However, it is important to further investigate the potential effectiveness of TRF in addressing sarcopenic obesity (SO), which is characterized by a combination of age-related obesity and sarcopenia. In this study, 14-month-old C57BL/6J male mice were fed either regular chow diet or high-fat diet (HFD), and had either ad libitum or restricted access to food for 8 hours daily (Intervention for 7 months). For the human trial (ChiCTR2100052876), obese individuals (n=21) with a Body Mass Index ≥28 were recruited and instructed to adopt an 8-hour eating window and a 16-hour fasting period. Here, we found that the TRF intervention significantly reduced global fat mass (P < .001) and volume (P < .05), and increase lean mass compared to mice fed with HFD. Furthermore, TRF improved overall metabolic mobility (8h TRF+HFD vs. AL+HFD). This intervention also enhanced liver FGF21 protein levels (P < .01) and the expression of FGFR1 and FGF21 target genes in adipose and muscle tissues, thus improving mitochondrial quality control in these tissues. Notably, TRF interventions led to a significant decrease in serum FGF21 levels (P < .05). In the human trial, TRF intervention resulted in a significant reduction in weight (P < .001) and body fat levels (P < .001) among obese individuals, as well as a decrease in serum GLU (P < .001), insulin (P < .001), and TC levels (P < .05). Overall, the findings indicate that TRF intervention improves SO by regulating liver FGF21 expression, thereby enhancing FGF21 sensitivity in adipose and muscle tissues. Show less

Interleukin-27 (IL-27) is a cytokine that is reported to be highly expressed in the peripheral blood of patients with pulmonary tuberculosis (PTB). IL-27-mediated signaling pathways, which exhibit anti- Mycobacterium tuberculosis (Mtb) properties, have also been demonstrated in macrophages infected with Mtb. However, the exact mechanism remains unclear. This study aimed to clarify the potential molecular mechanisms through which IL-27 enhances macrophage resistance to Mtb infection. Both normal and PTB patients provided bronchoalveolar lavage fluid (BALF). Peripheral blood mononuclear cells (PBMCs) were isolated from healthy individuals and stimulated with 50 ng/mL macrophage-colony stimulating factor (M-CSF) to obtain monocyte-derived macrophages (MDMs). Using 100 ng/mL phorbol 12-myristate 13-acetate (PMA), THP-1 cells were induced to differentiate into THP-1-derived macrophage-like cells (TDMs). Both MDMs and TDMs were subsequently infected with the Mtb strain H37Rv and treated with 50 ng/mL IL-27 prior to infection. The damage and inflammation of macrophages were examined using flow cytometry, enzyme-linked immunosorbent assay (ELISA), and Western blotting. Patients with PTB had elevated levels of IL-27 in their BALF. Preconditioning with IL-27 was shown to reduce H37Rv-induced MDMs and TDMs apoptosis while also decreasing the levels of Cleaved Caspase-3, Bax and the proinflammatory cytokines TNF-α, IL-1β, and IL-6, promoting the expression of Bcl-2 and the anti-inflammatory factors IL-10 and IL-4. Silencing of the IL-27 receptor IL-27Ra increased macrophage damage and inflammation triggered by H37Rv. Mechanistically, IL-27 activates autophagy by inhibiting TLR4/NF-κB signaling and activating the PI3K/AKT signaling pathway, thereby inhibiting H37Rv-induced macrophage apoptosis and the inflammatory response. Our study suggests that IL-27 alleviates H37Rv-induced macrophage injury and the inflammatory response by activating autophagy and that IL-27 may be a new target for the treatment of PTB. Show less

The aim of this review is to systematically explore the critical role of dual-specific phosphatases (DUSPs) in CKD-associated cognitive impairment and their therapeutic potential. Chronic kidney disease (CKD) is a global health burden, and the cognitive impairment it induces seriously affects patients' quality of life. Studies have shown that DUSPs are involved in pathological processes such as inflammation, oxidative stress, fibrosis, and neuronal apoptosis through the regulation of signaling pathways such as MAPK, which in turn affects the cognitive function of CKD patients. Specifically, downregulation of DUSP1 and DUSP6 expression in brain tissues of CKD patients is associated with cognitive impairment, whereas upregulation of DUSP8 and DUSP16 exacerbates cognitive deficits by promoting neuroinflammation. In addition, uremic toxins (e.g., indolephenol sulfate) can further deteriorate cognitive function by altering the activity of DUSPs and interfering with central nervous system signaling. Although there are currently no clinical drugs targeting DUSPs, small molecule inhibitors, gene modulation techniques, and natural compounds have demonstrated the potential to improve cognitive function by modulating DUSPs. Future studies need to focus on optimizing the specificity and selectivity of DUSPs inhibitors and conducting rigorous clinical validation. In-depth elucidation of the mechanism of action of DUSPs in the renal-brain axis will provide an important theoretical basis for the development of novel intervention strategies for CKD-associated cognitive impairment.

Left-behind adolescents in China may face heightened risks of involvement in cyberbullying due to their psychological vulnerability and complex social circumstances. Considering the potential heterogeneity within this population, this study aimed to identify distinct patterns of cyberbullying and cybervictimization among left-behind adolescents and to explore how reactive anger, left-behind patterns, gender, and grade level predict membership in these subgroups. A total of 1,351 junior high school students (752 left-behind, 599 non-left-behind) were recruited from five schools. Latent profile analysis (LPA) was used to identify distinct patterns, and multinomial logistic regression was used to examine the relationships between predictors and various profiles. (1) Three distinct profiles of cyberbullying and cybervictimization were identified among left-behind adolescents. (2) Left-behind adolescents were more likely to experience cybervictimization compared to their non-left-behind peers. (3) Reactive anger, left-behind patterns, gender, and grade level significantly predicted subgroup membership. These findings underscore the importance of developing targeted interventions and considering the specific psychosocial vulnerabilities of left-behind youth. Show less

The angiopoietin-like protein 4 (ANGPTL4), also known as fasting-induced adipose factor, is a secreted glycoprotein that belongs to the ANGPTL protein family. Due to its expression in various cell types and tissues and its interactions with other proteins, ANGPTL4 plays diverse roles within its family, exhibiting a wider range of molecular functions. For instance, ANGPTL4 is intricately involved in modulating central energy metabolism and enhancing exercise endurance, while also acting as a pivotal mediator in the interaction between gut microbiota and host lipid metabolism. Moreover, the expression of ANGPTL4 is directly controlled by aging-related signaling pathways. Its excessive activation accelerates the aging process by triggering mechanisms like heightened oxidative stress, epithelial-mesenchymal transition (EMT) and fibrosis, abnormal lipid accumulation, and cellular arrest, thereby advancing the development of age-related diseases. Given the pivotal roles of ANGPTL4 and its associated molecules in organ fibrosis and cancer advancement, targeting ANGPTL4 emerges as a promising therapeutic approach. However, the intricate and sometimes conflicting functions of the two cleavage fragments of ANGPTL4, namely N-terminal fragment (nANGPTL4) and C-terminal fragment (cANGPTL4), in different chronic diseases-exerting inhibitory or stimulatory effects depending on the disease stage-have posed challenges to the progress of ANGPTL4 antibody therapy. This review provides an overview of the biological mechanisms of ANGPTL4, its dual impact on fibrosis and tumorigenesis, and highlights its recent advancements as a potential biomarker in age-related diseases and inflammation-related conditions. ANGPTL4 is a high-potential but complex target, requiring mechanism-driven strategies for safe clinical translation. Show less

The co-occurrence of plasma cell neoplasm (PCN) and lymphoplasmacytic lymphoma (LPL) is rare, and their clonal relationship remains unclear. To evaluate the clinicopathologic characteristics of concomitant LPL/PCN. Retrospectively analyzed clinical and laboratory data of 14 cases. Three patients initially presented with immunoglobulin (Ig) M paraprotein, 1 with IgG paraprotein, and 10 had simultaneous diagnoses of PCN and LPL. In 13 cases, flow cytometry detected both LPL and PCN in marrow biopsies. Furthermore, immunohistochemistry highlighted the 2 neoplastic populations, demonstrating an increased proportion of plasma cells and their expression of cyclin D1, CD56, and/or a non-IgM isotype restriction. All cases exhibited discordant heavy-chain isotypes between LPL and PCN. Thirteen of the 14 cases (92.9%) had concordant light-chain restrictions between the 2 neoplasms, and the remaining case (7.1%) showed discordant light-chain restrictions. Of the 12 patients with follow-up, 5 were treated with myeloma regimens, 2 with LPL regimens, 3 with combined therapy, and 2 with observation alone. Follow-up ranged from 2 to 146 months (median, 12.5 months). One patient died of PCN progression, one died of comorbidity, and 10 patients were alive with or without disease. Survival analysis showed no significant difference from the control. The discordant heavy-chain isotype restrictions between PCN and LPL suggest biclonal B-cell neoplasms, which is supported by PCN's phenotypic distinction, such as the expression of cyclin D1 and/or CD56. However, our series exhibited a tendency toward concordant light-chain restrictions between the 2 neoplasms, raising the possibility that PCN may evolve from LPL through class switching. Show less

Zhigancao Decoction (ZGCD) is derived from "Treatise on Febrile Diseases" and is traditionally prescribed for treating a variety of cardiovascular conditions. As of now, there are no data to support its use as a treatment for diabetic cardiomyopathy (DCM) and the mechanism behind the effect is unclear as well. In the present study, clinical evidence for the efficacy of ZGCD in patients with DCM was examined using a meta-analysis and its underlying anti-DCM molecular mechanisms were explored via network pharmacology. The current study utilized an extensive search strategy encompassing various domestic and foreign databases databases to retrieve pertinent articles published up to June 2024. In light of this, a thorough evaluation of the benefits and safety of Zhigancao decoction (ZGCD) was conducted in this study using RevMan and Stata. Subsequently, a number of active compounds and target genes for ZGCD were gathered from the TCMSP and BATMAN-TCM databases, while the main targets for DCM were obtained from databases such as GenCards, OMIM, TTD, and DrugBank. To select core genes, protein-protein interaction networks were generated using the STRING platform, and enrichment analyses were completed using the Metascape platform. Meta-analysis results were ultimately derived from 9 studies involving 661 patients in total. In comparison with WM therapy alone, the pooled results showed that ZGCD significantly enhanced overall effectiveness. Additionally, the utilization of ZGCD was leading to a reduction in LVEDV, LVESV and LVDD, also a greater increase in LVEF. Meanwhile, the utilization of ZGCD during intervention was more effective in reducing SBP, and DBP. In addition, the ZGCD showed potential in reducing the occurrence of adverse events. In the context of network pharmacology, five constituents of ZGCD-namely lysine, quercetin, gamma-aminobutyric acid, stigmasterol, and beta-sitosterol-are posited to exert anti-diabetic cardiomyopathy (anti-DCM) effects through interactions with the molecular targets ASS1, SERPINE1, CACNA2D1, AVP, APOB, ICAM1, EGFR, TNNC1, F2, F10, IGF1, TNNI2, CAV1, INSR, and INS. The primary mechanisms by which ZGCD may achieve its anti-DCM effects are likely mediated via the AGEs/RAGE signaling pathway, as well as through pathways related to lipid metabolism and atherosclerosis. In comparison to WM therapy alone, ZGCD demonstrates greater efficacy and safety in the management of DCM. ZGCD not only significantly reduces blood pressure, but also enhances cardiac function while producing fewer adverse effects. The therapeutic effects of ZGCD on DCM can likely be ascribed to its capacity to modulate the AGEs-RAGE signaling pathway, as well as its efficacy in enhancing lipid metabolism and mitigating atherosclerosis. identifier (INPLASY202430133).

One serious consequence of diabetes mellitus is diabetic retinopathy (DR), which impairs eyesight to the point of blindness. While glucocorticoid medications are commonly employed in the management of DR, their therapeutic efficacy requires enhancement. Due to the tight association between glucocorticoid-related genes and the onset and development of DR, a comprehensive examination of its root cause of activity may be able to overcome the drawbacks of existing treatment approaches. R programming tools were used to examine the single-cell RNA sequencing (scRNA-seq) dataset GSE178121, which was obtained from the Gene Expression Omnibus (GEO) database. To evaluate glucocorticoid activity, a gene set related to glucocorticoid phenotypes was sourced from the Molecular Signatures Database (MSigDB), followed by the identification of key cellular populations within DR tissues. Subsequently, these key cells underwent pseudotime analysis, transcription factor (TF) evaluation, cell-cell communication assessment, differential gene screening, and the construction of a regulatory network. Our investigation demonstrated that vascular endothelial cells (VECs) in DR tissue exhibited markedly elevated glucocorticoid activity. KLF4 is among the TFs that are intimately linked to the onset of DR, and hydroxyurea could be a beneficial medication. Cell-cell communication analysis highlighted the PTN and ANGPTL signaling pathways as important signaling pathways in DR. In the meanwhile, we identified 25 Hub genes, including DUSP6, AP1S2, and PTPRB, which were verified to be differentially expressed in DR. In conclusion, our comprehensive study elucidated the complex interactions of glucocorticoids in the pathogenesis of DR, thereby revealing potential signaling pathways and therapeutic targets.

Recent researches highlight the interdependence of lipoprotein(a) [Lp(a)] and Lp(a)-associated cardiovascular risk with the background inflammatory burden. This study aimed to investigate whether systemic inflammation modulates Lp(a)-associated coronary stenosis in chronic coronary syndromes (CCS). A total of 1513 participants undergoing angiography at a tertiary cardiology center in China were included in our retrospective, cross-sectional study. Participants were categorized into normal, mild, and severe groups based on the Gensini Scores, which quantitatively assess stenosis severity. Multinomial logistic models were calculated according to accompanying systemic inflammation concentration. Participants with elevated Lp(a) levels had a high coronary stenosis risk: fully adjusted model odds ratios (ORs) [95% confidence intervals (CIs)] for the mild vs. normal and severe vs. normal groups were 1.47 (1.11-1.96) and 1.68 (1.21-2.33). Notably, the strongest Lp(a)-coronary stenosis associations after multi-variable adjustment persisted only in low inflammation concentration [systemic inflammation response index (SIRI) < 0.64)] [mild vs. normal, OR 2.03, 95% CI 1.17-3.54, Elevated Lp(a) correlates with coronary stenosis only in low inflammation concentration. Considering systemic inflammation in personalized Lp(a)-lowering therapies is more conducive for CCS managements. Show less

Dominant follicular development and atresia are governed by the proliferation of granulosa cells (GCs), a process influenced by the delicate balance between apoptosis and autophagy. Oxidative stress, a pivotal catalyst of GCs apoptosis, modulates gene expression through epigenetic mechanisms, including chromatin remodeling. Nevertheless, the regulatory mechanisms underpinning GCs functionality in relation to prolificacy remain inadequately elucidated. In this study, we discovered that the chromatin accessibility of nuclear receptor subfamily 1 group D member 1 (NR1D1) was markedly enhanced in dominant follicular GCs from low-prolificacy sheep, as evidenced by Assay for Transposase-Accessible Chromatin with high-throughput sequencing (ATAC-seq), which correlated with elevated NR1D1 transcript levels. Remarkably, NR1D1 emerged as a novel regulator of follicular development, exhibiting heightened expression in dominant follicles. The overexpression of NR1D1 induced cell cycle arrest, autophagy activation, and mitochondrial dysfunction via the AMPK pathway, while its knockdown fostered GCs survival and functionality. Furthermore, NR1D1 inhibits the transcription of HSD17B12, thereby contributing to oxidative stress (ROS)-induced apoptosis, as demonstrated by CUT&Tag-qPCR and dual luciferase assays. The downregulation of HSD17B12 partially alleviated the effects of NR1D1 knockdown on GCs functionality. These findings indicate that NR1D1 orchestrates GCs proliferation and apoptosis through the suppression of HSD17B12 and the activation of the AMPK pathway, establishing NR1D1 as a novel transcription factor implicated in follicular development and ovarian function, with significant implications for prolificacy.

This study aimed to comprehensively evaluate the clinical effectiveness and safety of acupuncture combined with repetitive transcranial magnetic stimulation (rTMS) in treating post-stroke cognitive impairment (PSCI) through meta-analysis and trial sequential analysis (TSA), moreover to provide an evidence-based basis for the treatment of PSCI in clinical practice. The study conducted a comprehensive search of eight major domestic and international databases, including PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP and China Biology Medicine (CBM). Four English and four Chinese databases of randomized controlled trials of acupuncture combined with rTMS for the treatment of PSCI from inception until July 2025. Systematic reviews and meta-analyses were conducted based on the Cochrane systematic review method by using RevMan5.4 and Stata/MP 18.0, and trial sequential analyses were performed by TSA 0.9. Sixteen RCTs involving 1,058 patients were included, including 532 patients in the experimental group and 526 patients in the control group. Meta-analysis results showed that the experimental group had a higher clinical effectiveness rate in treating patients with PSCI compared to the control group [RR = 1.29, 95% CI (1.08, 1.55), Acupuncture combined with rTMS can improve cognitive function, regulate daily living ability, and regulate neurotransmitter levels in patients with PSCI, which is worthy recommended in the clinic. However, due to limitations in sample size, inclusion quality and incomplete reporting, it is worth noting that more rigorously designed and high-quality studies are needed to further validate these conclusions.

Alzheimer's disease (AD) is an irreversible and progressive neurodegenerative disorder. The vicious circle between amyloid-β peptide (Aβ) overgeneration and microglial dysfunction is an important pathological event that promotes AD progression. However, therapeutic strategies toward only Aβ or microglial modulation still have many problems. Herein, inspired by the Aβ transportation, an Aβ-derived peptide (CKLVFFAED) engineered biomimetic nanodelivery system (MK@PC-R NPs) is reported for realizing BBB penetration and reprogram neuron and microglia in AD lesion sites. This hollow mesoporous Prussian blue-based MK@PC-R NPs carrying curcumin and miRNA-124 can down-regulate β secretase expression, thereby inhibiting Aβ production and reducing Aβ-induced neurotoxicity. Meanwhile, MK@PC-R NPs with excellent antioxidant and anti-inflammatory properties could normalize the microglial phenotype and promote Aβ degradation, providing neuroprotection. As expected, after treatment with MK@PC-R NPs, the Aβ burdens, neuron damages, neuroinflammation, and memory deficits of transgenic AD mice (APP/PS1 mice) are significantly attenuated. Overall, this biomimetic nanodelivery system with anti-Aβ and anti-inflammatory properties provides a promising strategy for the multi-target therapy of early AD. Show less

This study aimed to investigate the expression and clinical significance of interleukin-27 (IL-27) and forkhead box P3 (Foxp3) in oral squamous cell carcinoma (OSCC) tissues, analyze their co-expression correlations, and explore their potential as prognostic biomarkers and therapeutic targets for OSCC. Immunohistochemistry (IHC) was used to detect the expression of the two subunits of IL-27, IL-27p28 and Epstein-Barr virus-induced gene 3 (EBI3), and Foxp3 in OSCC tissues and normal tissues. Chi-square test was used to analyze the correlation between the expression of the three in OSCC tissues and the clinical pathological parameters of patients. The IHC results showed that the expressions of IL-27p28, EBI3 and Foxp3 proteins in OSCC tissues were all higher than those in normal control tissues( The expression levels of IL-27p28, EBI3 and Foxp3 in OSCC tissues are significantly upregulated, indicating that the three play important roles in the occurrence and development of OSCC tumors. Furthermore, its high expression is associated with various clinicopathological characteristics of OSCC patients and can be used as a potential indicator for evaluating the prognosis of OSCC patients.
