Negative Feedback Control of Hypothalamic Feeding Circuits by the Taste of Food

I. Research Background The taste of food has a significant impact on the feeding motivation of animals. Previous research has shown that taste, as a positive feedback signal, can enhance the feeding motivation of animals. However, in recent years, studies on whether taste also plays a role in suppressing feeding and helping achieve negative feedbac...

Structural Basis of Psychedelic LSD Recognition at Dopamine D1 Receptor

Structural Basis of LSD Recognition in Dopamine D1 Receptors Research Background and Problem Statement LSD (lysergic acid diethylamide) is a well-known hallucinogen that primarily exerts profound cognitive and perceptual effects by acting on various neurotransmitter receptors, including serotonin (5-HT) receptors and dopamine receptors. The 5-HT2A ...

Antisense Oligonucleotides Enhance SLC20A2 Expression and Suppress Brain Calcification in a Humanized Mouse Model

Antisense Oligonucleotide Enhances SLC20A2 Expression and Inhibits Brain Calcification in Humanized Mouse Models Background and Research Questions Primary Familial Brain Calcification (PFBC) is an age-related neurogenetic disorder, characterized by bilateral calcifications in brain regions such as the basal ganglia, thalamus, and cerebellum. PFBC p...

Glucagon Promotes Increased Hepatic Mitochondrial Oxidation and Pyruvate Carboxylase Flux in Humans with Fatty Liver Disease

Study on the Effect of Glucose Regulation on Hepatic Mitochondrial Oxidation and Pyruvate Carboxylase Flux in Patients with Fatty Liver Disease Research Background and Significance Metabolic-dysfunction-associated Steatotic Liver Disease (MASLD) has become one of the major challenges in global health in the 21st century. This condition is often acc...

Endothelial Metabolic Control of Insulin Sensitivity Through Resident Macrophages

Endothelial Cells Influence Insulin Sensitivity Through Metabolic Regulation of Resident Macrophages In recent years, metabolic diseases, especially insulin resistance and diabetes, have become significant global health issues. Muscle tissue, being one of the main organs for glucose metabolism in the human body, has its insulin sensitivity closely ...

Metabolic Regulation of the Glioblastoma Stem Cell Epitranscriptome by Malate Dehydrogenase 2

Paper Report: The Role of MDH2 in Epitranscriptomic Metabolic Regulation of Glioblastoma Stem Cells Introduction and Background Glioblastoma (GBM) is the most common and lethal primary brain malignant tumor in adults. GBM cells utilize a metabolic pathway known as the Warburg effect, which involves increased glucose uptake through aerobic glycolysi...

Amino Acid is a Major Carbon Source for Hepatic Lipogenesis

Research Report on the Relationship Between High Protein Diet and Liver Fat Synthesis Background and Significance Globally, the prevalence of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is gradually increasing, becoming a common issue among people with obesity and insulin resistance. The pathological development of this disease...

Hexokinase 2 Senses Fructose in Tumor-Associated Macrophages to Promote Colorectal Cancer Growth

Fructose Promotes Colorectal Cancer Growth by Modulating Tumor-Associated Macrophage Polarization Introduction In recent years, fructose intake has dramatically increased worldwide and is closely associated with obesity and metabolic syndrome, both of which are recognized risk factors for cancer development. Although previous studies have shown tha...

Multi-Omic Mapping of Human Pancreatic Islet Endoplasmic Reticulum and Cytokine Stress Responses Provides Genetic Insights into Type 2 Diabetes

Background and Research Motivation Globally, Type 2 Diabetes (T2D) is a common metabolic disease characterized by the combined effects of genetic and environmental factors leading to dysfunction and/or cell death of pancreatic β-cells, resulting in insufficient insulin secretion. Based on findings from Genome-Wide Association Studies (GWAS), over 6...
