p53 GENE MUTTION: Exons 5 and 6 of the p53 gene of five individuals were amplified and examined by Cleavase® Fragment Length Polymorphism (CFLP®) Analysis. The pattern marked "WT" is from an ...

The ATM gene (mutated in the disease ataxia telangiectasia) activates the p53 tumor suppressor protein in response to DNA damage, explaining the higher incidence of cancer in AT patients.

Another key discovery was a previously unnoticed p53 mutation (A276P) found in a subset of hTERT-RPE1 cells. This mutation weakened p53's ability to regulate certain genes but did not affect its ...
