p53 Information for Pathologists
Tumor suppressor gene at 17p13, 53 kDa. p53 ensures that cells repair any damaged DNA before cell division by inducing cell cycle arrest to allow time for:. DNA repair OR. To force the cell to undergo apoptosis via activation of bax gene (J Biomed Biotechnol 2011;2011:603925, Wikipedia - p53). Mutations are among most commonly detected genetic abnormalities in human neoplasia; however, presence of p53 mutation is usually not, by itself, specific enough for a diagnosis for malignancy, and its absence does not rule out malignancy.
Common Uses By Pathologists:
Differentiate malignant conditions, which are often p53+ (carcinoma in situ of urothelium and other sites, invasive carcinoma) from reactive and metaplastic conditions which are usually p53- (Am J Surg Pathol 2001;25:1074). May be useful to distinguish uterine serous carcinoma (p53+) from endometrioid carcinoma (usually p53-). May be useful as serum tumor marker (Arch Pathol Lab Med 2011;135:1570).
