One of the fundamental observations in oncology is that the rate of cancer malignancy increases with age, which applies to most human malignancies including breast cancer. Therefore, it is crucial to elucidate the mechanistic connection between aging and carcinogenesis. The NAD+-dependent sirtuin family, specifically SIRT3, the primary mitochondrial deacetylase, which...
SIRT3 is a mitochondrial-localized, NAD+-dependent deacetylase, tumor suppressor protein that functions to direct mitochondrial energy sensing and antioxidant proteins, increasing the efficiency of energy utilization, providing a redox balanced environment, and preventing aging-related diseases. One SIRT3 deacetylation target is NADP+-dependent isocitrate dehydrogenase 2 (IDH2), a key Krebs Cycle enzyme that...
