ABHD5 and colonic neoplasm: However, in colon cancer, OU et al. found that ABHD5 deficiency inhibited mitochondrial FAO in TAMs isolated from human and mouse tumor tissues, activated the PI3K/protein kinase B (PKB/Akt) pathway and promoted aerobic glycolysis (Warburg effect), which in turn inhibited AMP-activated protein kinase phosphorylation and p53 activity.
