In gastric cancer (GC), Ksucc of S100A10 and lactate dehydrogenase A (LDHA) is significantly increased in GC with inhibited degradation, enhancing tumour invasion and migration [115, 116], while desuccinylation of 2-oxoglutarate dehydrogenase (OGDH) by SIRT5 dampens its activity and subsequently suppresses tumorigenesis in GC [135]. This evidence concerns the gene LDHA and gastric cancer.
