The steps by which the gene p 53 responds to cellular stress and DNA damage to promote apoptosis or cell-cycle arrest and to explain why people wih one mutant copy of a recessive tumor-suppressor gene is at higher risk of cancer development when compared to people without the recessive gene. Introduction: p 53 is an essential tumor suppressor gene and it is stimulated by certain cellular stresses such as carcinogens, hypoxia, ionizing radiation, and oxidative stress. Once the gene p 53 get activated, it leads to cell-cycle arrest and induces apoptosis or promotes DNA repair through certain pathways.
