High-abundance serum proteins, mostly modified by N-glycans, are usually depleted from human sera to achieve in-depth analyses of serum proteome and sub-proteomes. In this study, we show that these high-abundance glycoproteins (HAGPs) can be used as valuable standard glycopeptide resources, as long as the structural features of their glycans have been well defined at the glycosite-specific level. By directly analyzing intact glycopeptides enriched from serum, we identified 1322 unique glycopeptides at 48 N-glycosites from the top 12 HAGPs (19 subclasses). These HAGPs could be further classified into four major groups based on the structural features of their attached N-glycans. Immunoglobins including IGHG1/2/3/4, IGHA1/2 and IGHM were mostly modified by core fucosylated and bisected N-glycans with rarely sialic acids. Alpha-1-acid glycoproteins (ORM1/2) and haptoglobins (HP) were mainly modified by tri-and tetra-antennary (40 %) N-glycans with antenna-fucoses and sialic acids. Complement components C3 and C4A/B were highly modified by oligo-mannose glycans. The other HAGPs including SERPINA1, A2M, TF, FGB/G and APOB mainly contain bi-antennary complex glycans with the common core structure and (sialyl-) LacNAc branch structures. These HAGPs are easily detected by LC-MS analysis and therefore could be used as standard glycopeptides for glycoproteomic methodology studies as well as possible clinical utilities. Show less

Skin color of poultry, an important economic trait, is related to breed, feed, environment, and other factors. In recent years, China's duck industry has developed rapidly, and duck products are welcomed by consumers. Different skin colors of ducks have different cooking methods. Black skinned duck, such as Yulin black duck, is more popular in China because they are considered more suitable for making soup, while other skin colors, such as Pekin duck, is used for roasting. In order to gain a deeper understanding of the genetic factors associated with differences in duck skin color, the transcriptomes and metabolomes of skin between Yulin black duck and Pekin duck from 15 (BSE15 vs. PSE15), 21 (BSE21 vs. PSE21) and 27 (BSE27 vs. PSE27) days of incubation were compared and analyzed. The transcriptome results showed that a total of 187 (118 up-regulated and 69 down-regulated), 417 (91 up-regulated and 326 down-regulated) and 137 (55 up-regulated and 82 down-regulated) differentially expressed genes (DEGs) were identified from BSE15 vs. PSE15, BSE21 vs. PSE21 and BSE27 vs. PSE27, respectively. The significantly enriched GO terms of biological process were positive regulation of melanin biosynthetic process, melanin biosynthetic process, cuticle development, melanin biosynthetic process from tyrosine, and melanocyte differentiation, which were potentially related to skin growth and development. Eleven significant pathways, highly enriched by DCT, TYR, ASIP, TYRP1, KIT, PHOSPHO2, CERS3, SGPP2, SPTLC3, DEGS2, PATJ, RBP7, AOX1, ETNPPL, HPGDS, and GAD1, were melanogenesis, tyrosine metabolism, vitamin B6 metabolism, sphingolipid metabolism, protein digestion and absorption, tight junction, alpha-linolenic acid metabolism, arachidonic acid metabolism, linoleic acid metabolism, nicotinate and nicotinamide metabolism, and alanine, aspartate and glutamate metabolism, which participated in regulating the development of duck skin during embryonic stage. The significantly different metabolites (SDMs) were mainly organoheterocyclic compounds, lipids and lipid-like molecules, organic oxygen compounds, organic acids and derivatives, including L-tyrosine, N-arachidonyl maleimide, glycerophospho-N-palmitoyl ethanolamine, LPE 22:4, and PC(0:0/18:0). which were mainly enriched in glycerophospholipid metabolism, arachidonic acid metabolism, linoleic acid metabolism, alpha-linoleic acid metabolism, and melanogenesis in metabolome, suggesting that these pathways may play important roles in skin development of duck during embryonic stage. Besides, the analysis of integrated transcriptome and metabolome indicated that the pathways, including glycerophospholipid metabolism, arachidonic acid metabolism, linoleic acid metabolism, and alpha-linolenic acid metabolism, could contribute to regulating skin development in embryonic duck. Our findings could help elucidate the genetic mechanisms underlying the development differences in duck skin color. Furthermore, the candidate genes and metabolites can be used to provide a valuable breeding strategy for the selection of specific duck breeds with ideal skin coloration. Show less

To identify the susceptibility loci for myopic macular neovascularization (mMNV) in patients with high myopia. A genome-wide association study (GWAS) meta-analysis (meta-GWAS). We included 2783 highly myopic individuals, including 608 patients with mMNV and 2175 control participants without mMNV. We performed a meta-analysis of 3 independent GWASs conducted according to the genotyping platform (Illumina Asian Screening Array [ASA] data set, Illumina Human610 BeadChip [610K] data set, and whole genome sequencing [WGS] data set), adjusted for age, sex, axial length, and the first to third principal components. We used DeltaSVM to evaluate the binding affinity of transcription factors (TFs) to DNA sequences around the susceptibility of single nucleotide polymorphisms (SNPs). In addition, we evaluated the contribution of previously reported age-related macular degeneration (AMD) susceptibility loci. The association between SNPs and mMNV in patients with high myopia. The meta-GWAS identified rs56257842 at TEX29- LINC02337 as a novel susceptibility SNP for mMNV (odds ratio [OR] Our study identified a novel locus associated with mMNV in high myopia. Subsequent analyses offered important insights into the molecular biology of mMNV, providing the potential therapeutic targets for mMNV.

Traumatic defects or non-union fractures presents a substantial challenge in the fields of tissue engineering and regenerative medicine. Although synthetic calcium phosphate-based biomaterials (CaPs) such as dibasic calcium phosphate anhydrate (DCPA) are commonly employed for bone repair, their inadequate cellular immune responses significantly impede sustained degradation and optimal osteogenesis. In this study, drawing inspiration from the key structure of an acidic non-collagenous protein-CaP complex (ANCPs-CaP) essential for natural bone formation, we prepared biomimetic mineralized dibasic calcium phosphate (MDCPA). This preparation utilized plant-derived non-collagenous protein Zein as the organic template and acidic artificial saliva as the mineralization medium. Physicochemical property analysis revealed that MDCPA is a complex of Zein and DCPA, which mimics the composite of the natural ANCP-CaP. Moreover, MDCPA exhibited enhanced biodegradability and osteogenic potential. Mechanistic insight revealed that MDCPA can be phagocytized and degraded by macrophages via the FCγRIII receptor, leading to the release of interleukin 27 (IL-27), which promotes osteogenic differentiation by osteoimmunomodulation. The critical role of IL-27 in osteogenesis is further confirmed using IL-27 gene knockout mice. Additionally, MDCPA demonstrates effective healing of critical-sized defects in rat cranial bones within only 4 w, providing a promising basis and valuable insights for critical-sized bone defects regeneration.

Polycystic ovary syndrome (PCOS) is frequently accompanied with metabolic dysfunctions, yet the causal relationships between metabolic factors and PCOS remain to be conclusively established and etiology-based therapies are lacking. To comprehensively identify the metabolic causal factors and potential drug targets for PCOS. This genetic association study was conducted using bidirectional two-sample Mendelian Randomization (MR), multivariable MR (MVMR) and drug-target MR. Considering metabolic sexual dimorphism, female-specific genome-wide association studies (GWASs) for metabolic factors were obtained. To ensure the robustness of the findings, an additional independent PCOS GWAS dataset was utilized for replication. The PCOS cohort included 10,074 PCOS cases (mean age 28 to 45 years) and 103,164 controls (mean age 27 to 60 years) of European ancestry. All participants were female. Employing two-sample MR analysis, we found that genetically proxied body mass index (BMI) (OR = 3.40 [95 % CI, 2.65-4.36]), triglyceride (TG) (OR = 1.54 [95 % CI, 1.17-2.04]), low-density lipoprotein cholesterol (LDL-c) (OR = 1.37 [95 % CI, 1.07-1.76]), and type 2 diabetes (T2D) (OR = 1.24 [95 % CI, 1.09-1.41]) were significantly associated with an increased risk of PCOS, whereas genetically predicted high-density lipoprotein cholesterol (HDL-c) (OR = 0.61 [95 % CI, 0.47-0.80]) decreased the odds of PCOS. Stepwise MVMR established a hierarchy of interactions among these metabolic factors, identifying BMI and HDL-c as the most prominent causal factors. Notably, drug-target MR analysis identified incretin-based therapeutics, PCSK9 inhibitors, LPL gene therapy, sulfonylureas, and thiazolidinediones as potential therapeutics for PCOS. All these findings were validated in an independent dataset. This study offered insights into the roles of obesity, diabetes, and dyslipidemia in PCOS etiology and therapeutics, underscoring the necessity for managing metabolic health in women and paving the way for tailored therapeutic strategies for PCOS based on its metabolic underpinnings.

The mechanism of hepatocarcinogenesis after sustained virological response (SVR) in hepatitis C virus (HCV) patients is unclear. We compared gene profiles of hepatocellular carcinoma (HCC) between HCV-SVR, steatotic liver disease (SLD), and HCV-non-SVR patients. This study analyzed 126 resected HCCs from patients with HCV and SLD, classifying them as HCV-SVR (n = 22), HCV-non-SVR (n = 56), and SLD (n = 48). Deep sequencing of 2910 hotspots in 55 cancer-related genes was conducted to examine mutations and copy number variations in both cancerous and background liver tissues. The HCV-SVR group comprised more patients who consumed alcohol (45.5% vs. 15.7%, p = 0.008), were obese (54.5% vs. 17.9%, p = 0.002), and had dyslipidemia (18.2% vs. 3.6%, p = 0.029) and hyperuricemia (18.2% vs. 3.6%, p = 0.029) than the HCV-non-SVR group. Mutational profiling of the HCV-SVR HCC showed significantly lower alteration rates of AXIN1 (13.6% vs. 42.9%, p = 0.016), ARID2 (9.1% vs. 39.3%, p = 0.013), and TP53 (9.1% vs. 32.1%, p = 0.030) than HCV-non-SVR patients. Compared with HCV-non-SVR-HCC, SLD-HCCs showed significantly lower rates of TERT promoter mutations (62.5% vs. 85.7%, p = 0.004), ARID2 alterations (12.5% vs. 39.3%, p = 0.003), and AXIN1 alterations (12.5% vs. 42.9%, p = 0.002). HCV-SVR/MASH/MASLD/ALD-HCC had significantly lower alteration rates of the Wnt/β-catenin (41.4% vs. 60.7%, p = 0.048) and chromatin remodeling pathways (27.1% vs. 48.2%, p = 0.026) than HCV-non-SVR-HCC. HCV-SVR HCC is linked to alcohol use and metabolic diseases, showing a mutational profile similar to SLD-HCC. Show less

Cognitive impairments in major depressive disorder (MDD) affect patients' social functioning, with underlying mechanisms involving gut microbiota and inflammatory factors remaining unclear. The study analyzed cognitive function, gut microbiota changes, and inflammatory factor levels in 39 unmedicated MDD patients and 41 healthy controls, employing correlation and moderation effect analysis. MDD patients scored lower than controls in cognitive functions like information processing speed, attention/vigilance, verbal learning, visual learning and social cognition. They showed reduced gut microbiota diversity and increased levels of inflammatory markers (TNF-α, IL-1, IL-6, IL-17, IL-27, IL-33). Sellimonas abundance correlated negatively with attention/vigilance, moderated by TNF-α, IL-27, and IL-33. This relationship was stronger at lower inflammation levels. MDD patients exhibit multi-domain cognitive dysfunction alongside pro-inflammatory states and disrupted gut microbiota. The abundance of Sellimonas significantly predicts attention/vigilance deficits. Inflammatory factors modulate the impact of gut microbiota on cognitive function, suggesting chronic low-grade inflammation as a key risk factor for cognitive impairment in MDD. Show less

Based on genetic studies, lysosome dysfunction is thought to play a pathogenetic role in Parkinson's disease (PD). Here we show that VPS13C, a bridge-like lipid transport protein and a PD gene, is a sensor of lysosome stress/damage. Upon lysosome membrane perturbation, VPS13C rapidly relocates from the cytosol to the surface of lysosomes where it tethers their membranes to the ER. This recruitment depends on Rab7 and requires a signal at the damaged lysosome surface that releases an inhibited state of VPS13C which hinders access of its VAB domain to lysosome-bound Rab7. While another PD protein, LRRK2, is also recruited to stressed/damaged lysosomes, its recruitment occurs at much later stages and by different mechanisms. Given the role of VPS13 proteins in bulk lipid transport, these findings suggest that lipid delivery to lysosomes by VPS13C is part of an early protective response to lysosome damage. Show less

Polychlorinated biphenyls (PCBs) are environmental pollutants associated with various health issues, including breast cancer. This study investigates potential molecular mechanisms by which PCBs may influence breast cancer progression using computational and preliminary experimental approaches. We conducted a differential expression analysis using the TCGA-BRCA dataset. PCBs-related toxicological targets were collected from the Comparative Toxicogenomics Database (CTD). Enrichment and pathway analyses identified candidate biological processes and pathways. Protein-protein interaction (PPI) networks were constructed to identify hub genes. Single-cell expression levels of key targets were analyzed (GSE114727 dataset). Molecular docking predicted binding affinities of PCBs congeners with key targets. Cell experiments assessed gene expression changes upon PCBs exposure. We identified 52 upregulated and 24 downregulated PCBs-related toxicological targets in breast cancer. Enrichment analysis highlighted potential associations with pathways such as PI3K-Akt, MAPK, and HIF-1, including genes like BRCA1, FGFR1, IGF1, AKT1, and EGF. PPI network analysis identified key hub genes like EZH2, EGF, BRCA1, AKT1, IL6, and TNF. Single-cell analysis suggested variable expression of key targets across immune cell types. Molecular docking predicted strong binding affinities of PCB 105 with EZH2 and EGF Our integrated analysis proposes that PCBs exposure may perturb key molecular pathways in breast cancer. Computational findings implicate targets like EZH2 and EGF, while preliminary cell experiments support further investigation. These results highlight a need for mechanistic studies to confirm PCB-induced effects and their therapeutic relevance, underscoring environmental pollutants as potential risk factors in cancer.

The SNP rs2414739 of Vacuolar protein sorting 13 homolog C(VPS13C) gene was identified to be linked with Parkinson's Disease (PD). Explore the clinical progression feature of PD patients with rs2414739 variant. Longitudinal data were obtained from the Parkinson's Progression Marker Initiative (PPMI) cohorts. Linear mixed models were used to test the effects of VPS13C with the progression of PD assessed by different scales. A total of 333 patients with PD were included and divided into rs2414739 carriers (n = 138) and noncarriers (n = 195). Patients with PD carrying VPS13C mutation had slower progression, assessed by total scores of MDS-UPDRS (II+III) (β = -1.834, p = 0.000, 95%CI: -2.767, -0.901) than noncarriers. The effect of VPS13C was significant both in the rate of change of UPDRS-II scores (β = -0.284, p = 0.028, 95%CI: -0.537, -0.031) and UPDRS-III scores (β = -0.894, p = 0.009, 95%CI: -1.558, -0.228). We further divided VPS13C carriers into heterozygous and homozygous carriers, and found that the rate of change of UPDRS(II+III) (β = -1.165, p = 0.039, 95%CI: -2.265,-0.062) scores and UPDRS-III scores (β = -9.521, p = 0.041, 95%CI: -18.524,-0.532) were significantly slow in heterozygous VPS13C carriers. There was only 20 homozygous VPS13C carriers, which was too small a sample to perform the analysis. VPS13C was associated with slow motor progression in PD patients. Show less

Biological age acceleration and disruptions in neurotrophin pathway signaling may significantly contribute to cancer-related cognitive impairment (CRCI) etiology. In this study, we evaluated the relationship of epigenetic age acceleration with cognitive function measures and circulating BDNF levels. Furthermore, we evaluated DNA methylation (DNAm) patterns to explore neurotrophin pathway associations with CRCI symptoms. In a longitudinal study, 51 newly diagnosed Adolescent and Young adult cancer patients and 8 age-matched healthy controls provided blood samples for DNAm and BDNF measurements with concurrent clinical assessments (#NCT03476070). We evaluated the relationship of epigenetic ageing with cancer status, circulating BDNF levels, and measured cognitive function. Next, we identified significant differentially methylated positions (DMPs), regions (DMRs), and significantly enriched pathways associated with BDNF and cognitive function outcomes. PhenoAge and GrimAge demonstrated significant age acceleration relative to non-cancer controls and worsening cognitive function symptoms, with accelerated GrimAge associated with decreasing BDNF levels. DMPs associated with 5 different cognitive function outcomes (FactCog Score, Response, Memory, Executive Function, Multi-Tasking) were mapped to genes within KEGG pathway HSA:04722 (Neurotrophin Signaling Pathway). Key enriched pathways relative to both subjective cognitive function and multiple objective cognitive measurement domains were also enriched with respect to BDNF levels, including Synapse (GO:0045202), Glutamatergic Synapse (GO:0098978), and Neuron Projection (GO:0043005). Cancer and cancer treatment lead to significant epigenetic age acceleration, which can influence neuronal health and CRCI symptom onset. Furthermore, DNAm patterns corroborate BDNF as a potential biomarker for CRCI and suggest neurotrophin pathways play a meaningful role in CRCI etiology. Show less

Colorectal cancer (CRC) is a leading cause of cancer mortality while diabetes is a recognized risk factor for CRC. Here we report that tirzepatide (TZP), a novel polypeptide/glucagon-like peptide 1 receptor (GIPR/GLP-1R) agonist for the treatment of diabetes, has a role in attenuating CRC growth. TZP significantly inhibited colon cancer cell proliferation promoted apoptosis in vitro and induced durable tumor regression in vivo under hyperglycemic and nonhyperglycemic conditions across multiple murine cancer models. As glucose metabolism is known to critically regulate colon cancer progression, spatial metabolomics results revealed that glucose metabolites are robustly reduced in the colon cancer regions of the TZP-treated mice. TZP inhibited glucose uptake and destabilized hypoxia-inducible factor-1 alpha (HIF-1α) with reduced expression and activity of the rate-limiting enzymes 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) and phosphofructokinase 1 (PFK-1). These effects contributed to the downregulation of glycolysis and the tricarboxylic acid (TCA) cycle. TZP also delayed tumor development in a patient-derived xenograft (PDX) mouse model accompanied by HIF-1α mediated PFKFB3-PFK-1 inhibition. Therefore, the study provides strong evidence that glycolysis-blocking TZP, besides its application in treating type 2 diabetes, has the potential for preclinical studies as a therapy for colorectal cancer used either as monotherapy or in combination with other anticancer therapies.

Inflammatory bowel disease (IBD) is a chronic, immune-mediated intestinal disorder driven by dysregulated immune responses in genetically susceptible individuals. Despite recent advances in treatment, more than 30% of patients either fail to respond initially or lose response over time, underscoring the need for a deeper mechanistic understanding of immunogenetic pathways and the development of individualized therapeutic strategies. We first discuss how newly identified susceptibility genes (e.g., IL23R, NOD2, BDNF, SLC) and their polymorphisms influence immune cell function and epithelial barrier integrity. Single-cell technologies have further revealed novel cell subsets and interactions underlying disease heterogeneity. We then explore the clinical efficacy of classical and emerging targeted therapies, including cytokine-specific biologics, JAK inhibitors, and novel strategies aimed at restoring regulatory T-cell function or blocking integrin-mediated lymphocyte trafficking. Additionally, we highlight promising therapeutic approaches such as fecal microbiota transplantation, microbial metabolite-based interventions, and nanotherapeutics. We further discuss how genetic insights and immune biomarkers can facilitate treatment personalization and improve prognostic stratification. Ultimately, this review emphasizes the transition from broad immunosuppression to precision medicine and proposes integrated approaches-combining multiomics profiling, immune monitoring, and novel therapeutics-to achieve sustained remission and improve long-term outcomes in IBD patients.

The triglyceride-glucose (TyG) index is a novel diagnostic marker for various metabolic and cardiovascular diseases. However, little is known about the association of the TyG index with plasma atherogenicity, especially with its latent forms. The aim of this study was to assess the potential of the use of the TyG index as a marker of atherogenic risk. A total of 202 men with normolipidaemia, aged 20-60 years, were enrolled in this study. Fasting biochemical parameters were measured. The TyG index was calculated as ln[triglyceride(mg/dL)×glucose(mg/dL)]/2. The diagnostic ability of the TyG index for detecting atherogenic risk was tested by receiver operating characteristic (ROC) curve analysis. A substantial portion of normolipidaemic men had deviations from the reference values for the indices calculated using apolipoproteins. Unfavorable values for the apolipoprotein (apo) B/apoA-I ratio, low-density lipoprotein cholesterol/apoB (LDL-C/apoB) ratio, and the atherogenic index (ATH index) were observed in 32.7%, 31.7%, and 14.4% of men, respectively. The results of ROC curve analysis showed that the TyG index had good diagnostic ability for identifying unfavorable apolipoprotein indices in normolipidaemic men. Thus, the TyG index can be a valuable additional marker for assessing latent atherogenic risk; it can provide useful information for the diagnosis and treatment of early atherosclerosis. Show less

Obesity is a chronic disease that contributes to the development of insulin resistance, type 2 diabetes (T2D), and cardiovascular risk. Glucose-dependent insulinotropic polypeptide (GIP) receptor (GIPR) and glucagon-like peptide-1 (GLP-1) receptor (GLP-1R) co-agonism provide an improved therapeutic profile in individuals with T2D and obesity when compared with selective GLP-1R agonism. Although the metabolic benefits of GLP-1R agonism are established, whether GIPR activation impacts weight loss through peripheral mechanisms is yet to be fully defined. Here, we generated a mouse model of GIPR induction exclusively in the adipocyte. We show that GIPR induction in the fat cell protects mice from diet-induced obesity and triggers profound weight loss (∼35%) in an obese setting. Adipose GIPR further increases lipid oxidation, thermogenesis, and energy expenditure. Mechanistically, we demonstrate that GIPR induction activates SERCA-mediated futile calcium cycling in the adipocyte. GIPR activation further triggers a metabolic memory effect, which maintains weight loss after the transgene has been switched off, highlighting a unique aspect in adipocyte biology. Collectively, we present a mechanism of peripheral GIPR action in adipose tissue, which exerts beneficial metabolic effects on body weight and energy balance. Show less

Standard models of lexical production assume that speakers access representations of meaning, grammar, and different aspects of sound in a roughly sequential manner (whether or not they admit cascading or interactivity). In contrast, we review evidence for a parallel activation model in which these representations are accessed in parallel. According to this account, word learning involves the binding of the meaning, grammar, and sound of a word into a single representation. This representation is then activated as a whole during production, and so all linguistic components are available simultaneously. We then note that language comprehension involves extensive use of prediction and argue that comprehenders use production mechanisms to determine (roughly) what they would say next if they were speaking. So far, theories of prediction-by-production have assumed sequential lexical production. We therefore reinterpret such evidence in terms of parallel lexical production. Show less

Dysregulated lipid metabolism promotes the progression of various cancer types, including breast cancer. The present study aimed to explore the lipidomic profiles of patients with breast cancer, providing insights into the correlation between lipid compositions and tumor subtypes characterized by hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) status. Briefly, 30 patients with breast cancer were categorized into four groups based on their HR and HER2 status: HR+ no HER2 expression (HER2-0), HR+ HER2-low; HR+ HER2-positive (pos) and HR- HER2-pos. The lipidomic profiles of these patients were analyzed using high-throughput liquid chromatography-mass spectrometry. The data were processed through principal component analysis (PCA), partial least squares-discriminant analysis (PLS-DA) and random forest (RF) classification to assess the lipidomic variations and significant lipid features among these groups. The profiles of the lipids, particularly triglycerides (TG) such as TG(16:0-18:1-18:1)+NH Show less

Subjects with HoFH, confirmed by the presence of 2 pathogenic variants in the genes mentioned above, included in the registry from 2013 to June 2023 with an updated review were analyzed. Of 71 included subjects with HoFH, 40.8% were women, aged 52 [24-62] years, 57 adults and 13 children. The median follow-up was 7 [4-13] years. Age of diagnosis was 14 [2-26] years, with 10% of ASCVD at diagnosis and 27% of current ASCVD at 40.6 (13.4) years of age; 38% were on PCSK9 inhibitors, 9 patients on lomitapide, 9 on LDL apheresis, and 1 patient on evinacumab. Subjects with more than 4 therapies achieved >80% reduction in LDLc. In the last visit, the median LDLc was 139.3 [89.4-204.2] mg/dL. ASCVD was strongly associated with male sex and family history of ASCVD, relative risk 5.26 (1.53-18.10) and 2.53 (1.03-6.26), P < .05, respectively. Only 18% and 10% meet the recommended LDLc goal in primary and secondary prevention respectively. The current situation of HoFH in Spain is better than expected, with marked reductions in LDLc levels with new treatments. In this population, recommended LDLc goals are difficult to achieve despite maximum lipid-lowering therapy. ASCVD has been reduced and delayed by 2 decades. Show less

Intracranial aneurysms (IAs) are the major cause of subarachnoid hemorrhage. Stent-assisted coiling, especially with the Neuroform Atlas stent (NAS), has proved more effective than coiling alone for treating these aneurysms. To perform a systematic review and meta-analysis to investigate the efficacy and safety of the NAS in treating IAs. A comprehensive literature search was conducted on PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and clinicaltrials.gov from inception until June 2024. We included studies on ruptured and unruptured IAs treated with the NAS, covering experimental, observational, and case series across all age groups. The aneurysm occlusion rate was assessed by using the Raymond-Roy classification (RROC). The mRS and adverse events related to stent use were also recorded. The statistical analysis was conducted on R Version 4.3.2 by using the packages "meta" and "metasens." We reported our results as proportions with their corresponding CIs. Meta-regression, leave-one-out, and sensitivity analyses were conducted to confirm the robustness of our results. A total of 42 studies including 2434 participants with a mean age of 51 to 73 years were included. Among angiographic outcomes, the final RROC 1/RROC 2 was achieved in 95% of the patients, final RROC 1 in 82%, RROC 2 in 12%, and RROC 3 in 5% of the patients. Additionally, 93% of the patients showed mRS grade 0, 5% showed mRS grade 1, 3% showed mRS grade 2, 2% showed mRS grade 3, 0% showed mRS grade 4, 0% showed mRS grade 5, and 1% showed mRS grade 6. All adverse events had a ≤5% rate. Due to limited cause-specific data, we were unable to analyze mortality specific to the stent placement and complications. Despite the large number of studies included, comparative studies were still observed to be scarce. Although the generalizability of our findings is limited, this study demonstrates that the NAS is highly effective for treating IAs, with high occlusion rates and a low incidence of adverse events. The stent's performance, supported by comprehensive analysis, highlights its safety and efficacy in managing both ruptured and unruptured aneurysms. Show less

To compare central nervous system (CNS) tumors, such as paraganglioma, low-grade glioma (LGG), and glioblastoma (GBM), in terms of driver genes and gene expression, and to investigate the roles of common driver genes and genes with altered expression in cellular proliferation mechanisms and their interactions. Mutation datasets for pheochromocytoma/paraganglioma, LGG, and GBM from The Cancer Genome Atlas (TCGA) database were used for driver gene prediction. Six datasets from the Gene Expression Omnibus (GEO) database were used for differential gene expression analysis. A hybrid approach combining clustering and computational biology methods was applied to identify driver genes. Gene expression analyses were repeated for two gene expression datasets for each tumor type, and the intersection of the results was taken. Protein interaction analyses, overall survival analyses, and carcinogenesis-related functional analyses were performed on the common driver genes and the genes with the most significant changes in expression. ATRX, NF1, MUC16, and TTN were identified as driver gene candidates for all three tumor types. FSTL5, GABRG2, VSNL1, and LPL were found to be the genes with the most altered expression across all tumor types. Our findings suggest that, while CNS tumors with similar symptoms share molecular features, they can be more accurately differentiated through detailed investigation of the expression and mutation burden of the identified genes. This may also help accelerate the treatment planning process. This study confirms that paraganglioma, LGG, and GBM may share common mutational and expressional gene patterns. The identified genes may serve as potential therapeutic targets in the treatment of glial and neuroendocrine tumors. Show less

Colorectal cancer (CRC) is a malignant tumor. Slug has been found to display a key role in diversified cancers, but its relevant regulatory mechanisms in CRC development are not fully explored. Hence, exploring the function and regulatory mechanisms of Slug is critical for the treatment of CRC. Protein expressions of Slug, N-cadherin, E-cadherin, Snail, HIF-1α, SUMO- 1, Drp1, Opa1, Mfn1/2, PGC-1α, NRF1, and TFAM were measured through western blot. To evaluate the protein expression of Slug and SUMO-1, an immunofluorescence assay was used. Cell migration ability was tested through transwell assay. The SUMOylation of Slug was examined through CO-IP assay. Slug displayed higher expression and facilitated tumor metastasis in CRC. In addition, hypoxia treatment was discovered to upregulate HIF-1α, Slug, and SUMO-1 levels, as well as induce Slug SUMOylation. Slug SUMOylation markedly affected mitochondrial biosynthesis, fusion, and mitogen-related protein expression levels to trigger mitochondrial stress. Additionally, the induced mitochondrial stress by hypoxia could be rescued by Slug inhibition and TAK-981 treatment. Our study expounded that hypoxia affects mitochondrial stress and facilitates tumor metastasis of CRC through Slug SUMOylation. Show less

The Weibull proportional hazards model was used to identify the nongenetic effects that affect length of productive life (LPL) of the Italian Mediterranean buffalo. Data were provided by the Italian National Association of Buffalo Breeders and included records of reproductive, productive, and linear type traits from 59,943 buffalo with first calving from 2002 to 2019. Data were divided into 4 geographical regions to determine whether the relationship between the investigated effects and LPL varied by region. Length of productive life was defined as the number of days from the first calving to culling for those buffaloes that were culled (uncensored) or to the date of the last test-day for those that are still alive (censored). The Weibull model included time-dependent effects of herd-year-season of calving, parity and stage of lactation, production as within-herd deviations, as well as time-independent effects of age at first calving, year of birth, type of reproduction (natural mating vs. AI), classifier, and ten linear type traits. The average duration of productive life was 1,604 days. Both year of birth and production level had a significant effect on culling risk. Moreover, culling risk decreased linearly across parities. The reference point for age at first calving relative to other classes was set at 35 months. A significant relationship between linear type traits and relative culling risk was also observed, being highest for buffaloes with the lowest linear scores. The results show that the Weibull model provides consistent and robust risk estimates. Therefore, this model would be recommended for future implementation of the first genetic evaluation of LPL in the Italian Mediterranean buffalo. Show less

This study aimed to investigate the effects of perioperative esketamine on postoperative depression and pain in patients undergoing laparoscopic total hysterectomy. 135 patients undegoing laparoscopic total hysterectomy were recruited and randomly allocated to three groups. Finally, a total of 127 patients were selected into the statistical analysis, with the final grouping information as follows: sufentanil group (S1, n = 44), sufentanil combined with 0.25 mg/kg esketamine group (SK1, n = 42) and sufentanil combined with 0.5 mg/kg esketamine group (SK2,n = 41) intraoperatively, then postoperative analgesia was maintained with sufentanil (2 µg/kg) via patient-controlled intravenous analgesia (PCIA) in all groups, while a 1 mg/kg dose of esketamine was added to the PCIA regimen for patients in groups SK1 and SK2. The peripheral blood serum brain-derived neurotrophic factor (BDNF) level, 5-hydroxytryptamine (5-HT) level, Hamilton Depression Scale (HAM-D) scores, visual analogue scale(VAS) scores and the number of PCIA button pressed times in perioperative period were collected. Meanwhile, the postoperative adverse effects including nausea, vomiting, dizziness, respiratory depression and hallucinations were collected and compared between the three groups. Relative to preoperative baseline levels, BDNF and 5-HT levels decreased at the 1th day(1d) post surgery in all groups(P < 0.05), and then followed by a gradual increase thereafter. Compared with S1 group, the SK1 and SK2 group showed significantly higher serum BDNF and 5-HT levels at 1d, 2d and 5d after operation (P < 0.05), and revealed even higher at 1d and 2d after operation in SK2 group(P < 0.05). The HAM-D scores at 1d, 2d and 5d post operation were significantly reduced in SK1 and SK2 group (P < 0.05) compared to S1 group, and decreased even lower at 1d and 2d postoperative in SK2 group(P < 0.05), but no significant difference was found among three groups at 1d before and the 7d after operation. Simultaneously, the VAS scores decreased significantly in SK1 and SK2 group at the 1th hour(1 h), 6 h, 12 h, 24 h, and 48 h after surgery (P < 0.05), and the PCIA button pressed times were also significantly reduced in SK1 and SK2 group (P < 0.05) during the postoperative 48 h. Furthermore, the SK1 and SK2 group showed the lower dosage of remifentanil during the surgery(P < 0.05). However, the postoperative adverse effects had no statistical differences among the three groups. The combined intraoperative and postoperative administration of esketamine was effective in alleviating postoperative depression and pain, without increasing adverse effects in patients undergoing laparoscopic total hysterectomy. Moreover, the 0.5 mg/kg dosage intraoperatively may have the better alleviation property of depression-related indicators.
