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, ...
