This tutorial describes the structure and function of the p53 protein, how its activity is regulated in cells, and how mutant versions of p53 can lead to cancer. TP53 mutations in human cancers: functional selection and impact on cancer prognosis and outcomes. species and other types of cancer: hormone receptor expression, genetic factors, contaminant exposure and infectious disease. [5] __Age, weight, exposure, to carcinogens, and genetics can increase how the risk factor could actually cause, __ How are the deaths of the sea lions potentially beneficial to scientific studies of human cancer?
