However, emerging evidence also suggests that SIRT5-mediated desuccinylation could potentiate tumorigenesis by inactivating succinate dehydrogenase complex subunit A (SDHA) in renal cell carcinoma [142], stabilizing GLS in breast cancer [13, 143], activating citrate synthase (CS) and serine hydroxymethyltransferase (HMT2) in colon cancer [144, 145] and inhibiting PKM2 in lung cancer [146]. The gene discussed is CS; the disease is hereditary clear cell renal cell carcinoma.
