Metabolic functions of peroxisomes in health and disease.

abstract：:TP53 is mutated in most types of human cancers and is one of the most popular genes in cancer research. The p53 protein is a sensor of multiple forms of genotoxic, oncogenic and non-genotoxic stress. It suppresses growth and controls survival of stressed cells, and as such, is the focal point of selection pressures in...
