Numerous studies have shown that CPT2 is oncogenic in hepatocellular carcinoma, colorectal carcinoma, renal clear cell carcinoma, and primary ovarian plasmacytoid carcinoma, and is associated with proliferation, migration, invasion, stemness, apoptosis, and chemo-resistance of cancer cells [125,126,127]. The gene discussed is CPT2; the disease is clear cell renal carcinoma.
