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...

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...

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...

Dysfunctional circadian clock accelerates cancer metastasis by intestinal microbiota triggering accumulation of myeloid-derived suppressor cells

Dysfunctional circadian clock accelerates cancer metastasis by intestinal microbiota triggering accumulation of myeloid-derived suppressor cells

Disruption of Circadian Rhythm Promotes Cancer Metastasis and Myeloid-Derived Suppressor Cell Accumulation Triggered by Intestinal Microbes Academic Background and Research Motivation Cancer metastasis is the leading cause of death for most cancer patients, with colorectal cancer (CRC) drawing significant attention due to its high global incidence ...

A Comprehensive Overview of NF1 Mutations in Iranian Patients

Comprehensive Overview of Mutations in Neurofibromatosis Type 1 Among Iranian Patients Neurofibromatosis type 1 (NF1) is a hereditary disease caused by mutations in the NF1 gene, characterized by almost complete penetrance and high phenotypic variability. This study aims to identify NF1 mutations in Iranian patients using whole-genome exome sequenc...
