Carnitine palmitoyltransferase 2 (CPT2), an enzyme involved in fatty acid oxidation, serves as a prognostic biomarker for colorectal cancer (CRC). Overexpression of CPT2 activates phosphorylated p53, enhancing its expression, which in turn suppresses tumor growth and induces apoptosis. Conversely, a deficiency in CPT2 leads to the prevalent hereditary disorder of long-chain fatty acid oxidation in skeletal muscle. Additionally, the downregulation of CPT2 correlates strongly with the advancement of multiple cancers, highlighting its importance in cancer research [1] [2].
