Anticancer genes are genes that, when ectopically overexpressed, specifically destroy tumour cells without harming normal cells.[1] This cell destruction can be due to a variety of mechanisms, such as apoptosis, mitotic catastrophe followed by apoptosis or necrosis, and autophagy. Anticancer genes emerged from studies on cancer cells in the late 1990s.[2]

Examples

The first anticancer gene to be isolated was Apoptin, a gene encoded by the chicken anaemia virus genome.[2] Brevinin-2R is a short anti-microbial peptide of only 25 amino acids, a so-called non-hemolytic defensin, isolated from the skin of the frog species Rana ridibunda.[3] The adenovirus E4orf4 is a viral protein with tumour-selective cell killing capabilities.[4] HAMLET encodes the milk protein α-lactalbumin and is active against cancer cells only when complexed with oleic acid.[5] Mda-7 (also known as IL-24) encodes a secreted cytokine and belongs to the IL-10 gene family.[6] Noxa, is a BH3-only protein of the Bcl-2 family, has recently been discovered as a specific killer of breast cancer cells.[7] Parvovirus-H1 NS1 is another viral protein carrying tumour-selective apoptosis capabilities.[8] ORCTL3, a cation transporter, was recently discovered as a novel anti-cancer gene.[9] Par-4 encodes a protein that features a leucine zipper and mediates many diverse signals for apoptosis at its endogenous expression level.[10] TRAIL (TNF related apoptosis-inducing ligand) is a member of the TNF family of apoptosis-inducing ligands [11]TP53 is another anti-cancer/anti-tumor gene (elephants have twenty copies of the TP53 gene).

Some of these genes are in clinical development. TRAIL, Mda-7, HAMLET are the clinically most advanced anticancer genes.
