p53 is a tumor suppressor gene and transcription factor. Due to DNA mutations and other cell stress signals p53 helps to start transcription of genes that trigger cell cycle arrest, apoptosis and DNA repair. Mutations in p53 gene lead to loss of tumor suppressor function. In normal cells p53 exists at very low almost undetectable levels as it has a short half-life period. In malignant cells p53 is overexpressed and shows a greatly increased half-life. Overexpression is found in more than 50 % of human cancers and may be associated with aggressive progression and poor prognosis. Antibody p53 may be helpful in detection of carcinomas of colon, breast, lung, prostate and ovary.
