Ferroptosis Triggered by Spliceosomal GTPase EFTUD2 Deficiency Leads to Purkinje Cell Degeneration

Depletion of EFTUD2 Triggers Ferroptosis-Induced Degeneration of Cerebellar Purkinje Cells Background and Motivation The cerebellum plays a crucial role in motor coordination and higher cognitive functions, with the health of cerebellar Purkinje cells (PCs) being essential for maintaining cerebellar function. Gene regulation based on alternative sp...

Disruption of Nuclear Speckle Integrity Dysregulates RNA Splicing in C9orf72-FTD/ALS

Disruption of Nucleolar Integrity and Dysregulation of RNA Splicing in C9orf72-FTD/ALS Background and Research Motivation The hexanucleotide repeat expansion (GGGGCC)n in the C9orf72 gene is the most common genetic cause of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). Studies have shown that these repeat sequences not only...

The Role of Motor Cortex in Striatal Motor Dynamics and Execution of Skilled and Unskilled Actions

Exploring the Crucial Role of the Motor Cortex in Basal Ganglia and Dynamic Motor Control Research Background and Motivation The role of the motor cortex (Motor Cortex, M1) in motor generation and regulation has long been a significant topic in neuroscience. The interaction between M1 and the striatum in selecting and executing goal-directed action...

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 ...

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...

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

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...

GPR56-mediated sensing of the steroid hormone 17α-hydroxypregnenolone protects against ferroptosis-induced liver injury

The Role of Protein-Coupled Receptor GPR56 and Its Protective Mechanism in Ferroptosis-Induced Liver Injury In recent years, ferroptosis has emerged as a new form of programmed cell death, becoming a hot topic in scientific research. It is characterized by cell death due to phospholipid peroxidation and is significantly different from traditional a...

Cytosolic Calcium Regulates Hepatic Mitochondrial Oxidation, Intrahepatic Lipolysis, and Gluconeogenesis via CaMKII Activation

Background Introduction In the field of cellular energy metabolism research, mitochondrial calcium ion ([Ca²⁺]mt) is considered an important node in regulating mitochondrial oxidative function. Its role mainly involves activating calcium-sensitive dehydrogenases in the tricarboxylic acid cycle (TCA), including isocitrate dehydrogenase (IDH) and α-k...
