TM7SF3 Controls TEAD1 Splicing to Prevent MASH-Induced Liver Fibrosis

Background Introduction In modern society, metabolic dysfunction-associated steatotic liver disease (MASLD, previously NAFLD) is a common and serious chronic liver disease. However, the current understanding of its pathological mechanisms is not complete, including its progression to metabolic dysfunction-associated steatohepatitis (MASH), liver fi...

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...

Short-Term Cold Exposure Induces Persistent Epigenomic Memory in Brown Fat

Short-term Cold Exposure Induces Persistent Epigenomic Memory in Brown Adipose Tissue Background Brown Adipose Tissue (BAT) is the primary non-shivering thermogenic organ in mammals that dissipates chemical energy as heat under cold stimuli. BAT is characterized by a high density of mitochondria containing Uncoupling Protein 1 (UCP1), which generat...

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...

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...

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. Studies have shown that maintaining bone health and preventing osteoporosis are closely linked to mechanical load....

Imaging Brain Glucose Metabolism In Vivo Reveals Propionate as a Major Anaplerotic Substrate in Pyruvate Dehydrogenase Deficiency

Imaging Study of Brain Glucose Metabolism in Patients with Pyruvate Dehydrogenase Deficiency Background In modern mitochondrial medicine, evaluating the spectrum of brain diseases has been a limiting challenge. This limitation hinders our ability to understand the mechanisms behind the imaging phenotypes of the brains of mitochondrial disease patie...

Clinicopathologic and Neuroimaging Correlations of Nonverbal Oral Apraxia in Patients with Neurodegenerative Disease

Nonverbal Oral Apraxia in Patients with Neurodegenerative Diseases: Clinical-Pathological and Neuroimaging Correlations Research Background Nonverbal Oral Apraxia (NVOA) is a condition characterized by the inability to plan, sequence, and execute voluntary oral-facial movements without muscle weakness. NVOA was first identified in stroke patients, ...

Pathologic Substrates of Structural Brain Network Resilience and Topology in Parkinson Disease Decedents

Scientific Paper News Report: Pathological Basis and Topological Properties of Structural Brain Networks in Parkinson’s Disease Patients Background and Research Objectives In Parkinson’s disease (PD), α-synuclein spreads between connected brain regions, leading to neuronal loss and brain network disruption. Using diffusion-weighted imaging (DWI), t...
