Tumor Metabolism

LYSET is an important Golgi membrane protein that maintains the correct trafficking of lysosomal enzymes by regulating GNPT and the mannose-6-phosphate pathway. Under nutrient-limited conditions, some cancer cells depend on lysosomal degradation of extracellular proteins to obtain amino acids, ...

Mitochondria maintain the energy supply, biosynthesis, and redox homeostasis of tumor cells through oxidative phosphorylation, the TCA cycle, and substrate oxidation. Certain tumors and treatment-persistent cells can develop specific mitochondrial metabolic dependencies, making OXPHOS, substrate ...

MTAP loss disrupts the methionine salvage pathway, resulting in the accumulation of 5′-methylthioadenosine (MTA) and partial inhibition of PRMT5 activity. Cancer cells consequently enter a state with limited PRMT5 functional reserve and develop greater dependence on residual PRMT5 activity and ...

Disulfidptosis is a form of regulated cell death driven by abnormal intracellular disulfide accumulation and collapse of the actin cytoskeleton. It typically occurs in cells with high SLC7A11 expression under conditions of restricted glucose utilization and insufficient NADPH supply, reflecting ...

Glycolytic rate-limiting enzymes determine the key nodes from glucose uptake and flux commitment to pyruvate formation. Hexokinase, phosphofructokinase, and pyruvate kinase respectively control early substrate trapping, irreversible mid-pathway flux commitment, and terminal ATP generation in ...
