Decoding Human Biology and Disease Using Single-Cell Omics Technologies

Decoding Human Biology and Disease with Single-Cell Omics Technologies Background Introduction Cells are the fundamental units of life. A single fertilized egg can develop into an entire complex human body, composed of approximately 37 trillion cells organized into various tissues, organs, and systems. Traditional cell classification methods primar...

Patient Assessment and Therapy Planning Based on Homologous Recombination Repair Deficiency

Application of Homologous Recombination Deficiency (HRD) in Tumor Patient Assessment and Treatment Planning Background Homologous Recombination (HR) is an important mechanism for repairing DNA Double-Strand Breaks (DSBs). However, when key genes in the HR repair pathway are mutated or epigenetically inactivated, cells are unable to effectively repa...

Transketolase Promotes MAFLD by Limiting Inosine-Induced Mitochondrial Activity

Background Introduction Metabolic dysfunction-associated fatty liver disease (MAFLD) is a globally prevalent chronic liver disease with an incidence rate of about 25%. Its prevalence is even higher among obese and type 2 diabetic populations. MAFLD is a complex systemic disease that can progress from metabolic-associated fatty liver (MAFL) to metab...

Glucagon-like peptide 1 receptor is a T cell-negative costimulatory molecule

Role of GLP-1R in T Cells and Its Regulatory Mechanism for Anti-transplant Immunity and Anti-tumor Immunity Academic Background Glucagon-like peptide-1 receptor (GLP-1R) is known as a key regulator of glucose metabolism, primarily expressed in pancreatic β cells. Previous studies have clarified that GLP-1R agonists have significant effects in reduc...

QDPR Deficiency Drives Immune Suppression in Pancreatic Cancer

Background Pancreatic Ductal Adenocarcinoma (PDAC) is a malignancy with a highly immunosuppressive tumor microenvironment (TME), showing strong resistance to immune checkpoint blockade (ICB) therapies, such as anti-PD-1 and anti-CTLA-4 treatments. Myeloid-Derived Suppressor Cells (MDSCs) derived from tumors play a critical role in tumor immune supp...

Acetyl-CoA Carboxylase Obstructs CD8+ T Cell Lipid Utilization in the Tumor Microenvironment

Inhibition of Acetyl-CoA Carboxylase Enhances Antitumor Immunity of Tumor-Infiltrating CD8+ T Cells Background and Objective In recent years, the impact of metabolic changes in the Tumor Microenvironment (TME) on the function of Tumor-Infiltrating Lymphocytes (TILs) has become a hot topic in immunological research. Although T cells possess strong a...

Glycometabolic Reprogramming-Induced XRCC1 Lactylation Confers Therapeutic Resistance in ALDH1A3-Overexpressing Glioblastoma

Background Glioblastoma (GBM) is the most common and aggressive malignant primary brain tumor in adults, characterized by high recurrence and mortality rates. Despite active chemotherapy and radiotherapy post-surgery, GBM remains insensitive to existing treatment regimens, and patients usually have a poor prognosis. Recent studies indicate that the...

Nicotinamide Metabolism Face-off Between Macrophages and Fibroblasts Manipulates the Microenvironment in Gastric Cancer

Macroscopic and Microscopic Mechanisms of Nicotinamide Metabolism Antagonism: Manipulation of the Gastric Cancer Microenvironment Background Introduction Gastric cancer (GC) is a type of cancer characterized by a unique and heterogeneous tumor microenvironment (TME). Despite advances in immune checkpoint blockade (ICB) therapy for gastric cancer, n...

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...

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...
