Leptin Receptor Reactivation Restores Brain Function in Early-Life lepr-Deficient Mice

Reactivation of Insulin Receptors Can Restore Brain Function in Early Lepr-Deficient Mice Background Obesity is a chronic disease caused by excessive fat accumulation, affecting both body and brain health. Deficiency of the insulin receptor (Leptin receptor, Lepr) is considered an important factor in the pathogenesis of obesity. Insulin plays a cru...

TM7SF3 Controls TEAD1 Splicing to Prevent MASH-Induced Liver Fibrosis

Background Introduction In modern society, metabolic dysfunction-associated steatotic liver disease (MASLD, previously NAFLD) is a common and serious chronic liver disease. However, the current understanding of its pathological mechanisms is not complete, including its progression to metabolic dysfunction-associated steatohepatitis (MASH), liver fi...

Short-Term Cold Exposure Induces Persistent Epigenomic Memory in Brown Fat

Short-term Cold Exposure Induces Persistent Epigenomic Memory in Brown Adipose Tissue Background Brown Adipose Tissue (BAT) is the primary non-shivering thermogenic organ in mammals that dissipates chemical energy as heat under cold stimuli. BAT is characterized by a high density of mitochondria containing Uncoupling Protein 1 (UCP1), which generat...

Tirzepatide Modulates the Regulation of Adipocyte Nutrient Metabolism through Long-Acting Activation of the GIP Receptor

Study Reveals Tirzepatide Regulates Adipocyte Nutritional Metabolism Through Long-Acting Activation of GIP Receptor Academic Background With global chronic nutritional excess and lack of exercise, obesity and type 2 diabetes (T2D) and their related complications (such as cardiovascular diseases) have reached epidemic levels. These conditions not on...

Obesity Disrupts the Pituitary-Hepatic UPR Communication Leading to NAFLD Progression

Obesity Disrupts the Pituitary-Hepatic UPR Communication Leading to NAFLD Progression

Obesity Disrupts Pituitary-Hepatic UPR Communication Leading to NAFLD Progression Background and Research Objectives In recent years, the incidence of non-alcoholic fatty liver disease (NAFLD) has increased significantly. Research suggests that obesity, a major risk factor for NAFLD, disrupts hepatic immunometabolic homeostasis by affecting systemi...

A Human Omentum-Specific Mesothelial-Like Stromal Population Inhibits Adipogenesis Through IGFBP2 Secretion

A Human Omentum-Specific Intermesothelial Fibroblast Population Inhibits Adipogenesis by Secreting IGFBP2 Background and Research Objective With the growing prevalence of obesity and metabolic diseases, the plasticity and heterogeneity of adipose tissue have become research hotspots. Different regions of adipose tissue exhibit distinct metabolic ch...

Cytosolic pH is a Direct Nexus in Linking Environmental Cues with Insulin Processing and Secretion in Pancreatic β Cells

Cytosolic pH is a Direct Nexus in Linking Environmental Cues with Insulin Processing and Secretion in Pancreatic β Cells

The Direct Link between Cytosolic pH and Environmental Signals, Insulin Processing, and Secretion in Pancreatic β Cells Background Pancreatic β cells respond to glucose fluctuations by regulating insulin processing and secretion. However, how this process is finely tuned within a complex and variable microenvironment, and whether its dysfunction is...

A 5:2 Intermittent Fasting Regimen Ameliorates NASH and Fibrosis and Blunts HCC Development

New Scientific Discovery: The 5:2 Intermittent Fasting Regimen Improves Non-Alcoholic Steatohepatitis and Reduces Hepatocellular Carcinoma Occurrence Research Background and Problem Statement Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide, with its prevalence increasing alongside rising obesity rates. N...

COQ7 Defect Causes Prenatal Onset of Mitochondrial CoQ10 Deficiency with Cardiomyopathy

Perinatal onset of mitochondrial CoQ10 deficiency due to COQ7 defect with cardiomyopathy and gastrointestinal obstruction Background Coenzyme Q10 (CoQ10) is a lipid-soluble molecule with antioxidant properties and a key component in electron transfer during oxidative phosphorylation in mitochondria. CoQ10 deficiency is a rare mitochondrial metaboli...

Validity of European-Centric Cardiometabolic Polygenic Scores in Multi-Ancestry Populations

Effectiveness of European-derived Cardiometabolic Polygenic Scores in Multi-ancestral Populations In recent years, Polygenic Scores (PGS) have received widespread attention as a tool for assessing individual genetic risk. However, most existing PGS are based on Genome-Wide Association Studies (GWAS) data from white European populations. This has le...
