p53

p53 helps in the regulation of transcription of variety of genes in response to different type of signals which are related to stress Riley et al.). p53 regulates the GI epithelial cells (Kirsch et al.).

Types of p53:
1. Mutant p53:
This type of p53 is responsible for transformation at 37.5 C whereas at 32.5 C it suppresses transformation working similar as that of wild type p53.

2. Wild type p53:
This type of p53 is not oncogenic and causes prevention of transformation. In human carcinogenesis, this type of p53 work as suppressor gene. (Michalovitz et al.)

p53 Pathway:
It is found to mediate stress responses in the cells. p53 has the ability of initiating repair of DNA, cell cycle arrest, senescence and apoptosis. (Vazquez et al.)
