Plant-derived compounds have recently gained attention owing to their better safety profile and multi-targeted actions. Charantin, a plant-based natural compound known for its diverse pharmacological properties, was investigated for its anti-hyperlipdemic activity using both in-silico and in-vivo approaches. A detailed network pharmacology analysis was used to predict charantin-related targets, cross-referenced with hyperlipidemia-associated genes from GeneCards, DisGeNET, and CTD. Shared targets were subjected to protein-protein interaction analysis and functional enrichment using STRING, Cytoscape, and ShinyGO. Molecular docking studies assessed charantin's binding interactions with key lipid-regulating proteins (HMGCR, PCSK9, LDLR, PPAR-α, PI3K). In-vivo efficacy of charantin (100 and 200 mg/kg) was evaluated in Sprague-Dawley rats fed with high-lipid diet (HLD) for 12 days. Lipid profiles, liver enzymes and transcript levels of lipid-regulating genes were analyzed. A total of 242 overlapping genes were identified between charantin targets and hyperlipidemia-associated genes, with enrichment analyses highlighting key lipid metabolic and inflammatory pathways. Molecular docking revealed that charantin exhibited stronger binding affinities than simvastatin across multiple targets. In HLD animal model, charantin significantly reduced total cholesterol, triglycerides, LDL, and VLDL, while increasing HDL levels in a dose-dependent manner. Liver function remained preserved, accompanied by downregulation of HMGCR, PCSK9, and APOB, and upregulation of LDLR and PPAR-α at both gene and protein levels. Charantin exerts potent lipid-lowering effects through modulation of multiple pathways, including cholesterol biosynthesis, lipoprotein metabolism, and nuclear receptor activation. Its efficacy and hepatoprotective properties reiterate its potential as a safe, effective alternative or adjunct to conventional therapies for hyperlipidemia. Show less

The United Arab Emirates (UAE), with its characteristic local population, geography, and history, presents several risk factors for cardiovascular diseases (CVDs) in obese individuals. Obesity and its associated complications, including diabetes, atherogenic dyslipidemia, and CVDs leading to significant health risks. In the present study, "Youths" defined as young people between 18 and 22 years. We assessed dyslipidemia, inflammation, and oxidative stress biomarker levels and their association with endothelial dysfunction (ED) in both overweight/obese and normal weight youths of UAE. There were 160 youths with overweight/obese (BMI ≥ 25 kg/m The overall mean age and male-to-female ratio were 20±1.5years and 1.0:1.2, respectively. There was statistically significant difference in HDL-C (p<0.001), triglycerides (TG) (p<0.001), ApoA (p=0.002), ApoB/ApoA ratio (p=0.009) between the overweight/obese and normal weight youths. Among, inflammatory markers: hs-CRP, IL-6, TNF-α also showed significant p<0.001 and oxidative stress markers: DNA/RNA Damage, catalase and nitric oxide (NO) showed significant p<0.001 between groups. Spearman correlation of ED markers with lipid profile markers showed Vitamin C levels positively correlated with HDL-C (p<0.001) and negatively correlated with glucose (p<0.001). ICAM-1showed significant negative correlation with HDL-C (p<0.01) and ApoA (p<0.001) but positive correlation with TG (p<0.01) and HbA1c (p<0.001) among groups. Spearman correlation of ED markers with inflammatory/oxidative stress biomarkers showed Vitamin C levels negatively correlated with ferritin (p < 0.001), NO (p < 0.001), GGT (p < 0.001), and ALT (p < 0.001) levels. The ICAM-1showed significant positive correlation with hs-CRP (p < 0.01), IL-6 (p < 0.001), TNF-α (p < 0.01), GGT (p < 0.05), and ALT (p < 0.05) in both groups. This study revealed a strong link between the biomarkers of dyslipidemia, inflammation, and oxidative stress with ED in overweight/obese patients. This study might be used to predict future cardiovascular events in this population. Show less

Application of next-generation sequencing may lead to the detection of secondary findings (SF) not related to the initially analyzed disease but to other severe medically actionable diseases. However, the analysis of SFs is not yet routinely performed. We mined whole-exome sequencing data of 231 pediatric cancer patients and their parents who had been treated in our center for the presence of SFs. By this approach, we identified in 6 children (2.6%) pathogenic germline variants in 5 of the noncancer-related genes on the American College of Medical Genetics and Genomics (ACMG) SF v3.0 list, of which the majority were related to cardiovascular diseases ( RYR2 , MYBPC3 , KCNQ1 ). Interestingly, only the patient harboring the KCNQ1 variant showed at the time point of the analysis signs of the related Long QT syndrome. Moreover, we report 3 variants of unknown significance which, although not classified as pathogenic, have been reported in the literature to occur in individuals with the respective disease. While the frequency of patients with SFs is low, the impact of such findings on the patients' life is enormous, with regard to the potential prevention of life-threatening diseases. Hence, we are convinced that such actionable SF should be routinely analyzed. Show less
