A Microbial Metabolite Inhibits the HIF-2α-Ceramide Pathway to Mediate the Beneficial Effects of Time-Restricted Feeding on MASH

A Microbial Metabolite Mediates the Beneficial Effects of Time-Restricted Feeding on MASH by Inhibiting the HIF-2A-Ceramide Pathway Introduction Background: Metabolic Dysfunction-Associated Steatotic Liver Disease/Metabolic Dysfunction-Associated Steatohepatitis (MASLD/MASH) is a major health problem affecting a quarter of the global population. MA...

Dopaminylation of endothelial TPI1 suppresses ferroptotic angiocrine signals to promote lung regeneration over fibrosis

Dopamine Modification of TPI1 Inhibits Ferroptosis Signaling in Vascular Endothelial Cells, Promoting Lung Regeneration and Inhibiting Fibrosis Background The regenerative capability of the lung enables it to restore its original functional tissue after injury. However, if this regenerative process is disrupted, it often leads to maladaptive repair...

Electron Transport Chain Inhibition Increases Cellular Dependence on Purine Transport and Salvage

Inhibition of the electron transport chain increases cell dependence on purine transport and salvage Research Background The electron transport chain (ETC) is a key mechanism in mitochondria responsible for energy generation, playing an important role in maintaining cellular homeostasis and growth. However, it remains unclear how cells adjust their...

Diabetic Retinopathy is a Ceramidopathy Reversible by Anti-Ceramide Immunotherapy

Diabetic Retinopathy as a Ceramide Disease Reversible by Anti-Ceramide Immunotherapy Background Diabetic Retinopathy (DR) is one of the most common metabolic disorders worldwide. Diabetes not only leads to chronic complications in macrovascular and microvascular systems but also imposes significant socio-economic burdens. As a microvascular complic...

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...

A novel protein cytb-187aa encoded by the mitochondrial gene cytb modulates mammalian early development

The New Protein Cytb-187aa Regulates Mammalian Early Development Academic Background Mitochondria are multifunctional organelles that provide energy for cells. In addition to energy supply, they are involved in the regulation of apoptosis, cell signaling, and various biosynthetic pathways. Among these functions, substances within mitochondria can b...

Oncogenic Fatty Acid Oxidation Senses Circadian Disruption in Sleep-Deficiency-Enhanced Tumorigenesis

Fatty Acid Oxidation in Lung Cancer Patients Induced by Sleep Loss Promotes Tumorigenesis Through Circadian Rhythm Disruption Background and Research Motivation Circadian rhythm regulation is one of the critical mechanisms for animals to maintain physiological homeostasis. However, disruptions in circadian rhythms have become a common phenomenon du...

Gut Microbial Alterations in Arginine Metabolism Determine Bone Mechanical Adaptation

The Role of Gut Microbial Changes in Lysine Metabolism on Bone Mechanical Adaptation Research Background Osteoporosis, a severe global public health issue, affects over 200 million people, posing significant threats to health and life.
