Study Of Hypoxia And New Gene Reveals Early-stage Action Of P53 Tumor Suppressor Gene

Researchers have known for a decade that the p53 tumor suppressor gene is important for killing cells as they proliferate under low-oxygen conditions inside tumors. As tumors grow they outstrip their oxygen supply. If a cell has a normal p53 gene, the p53 protein will eliminate cancerous cells, keeping tumor growth at bay. Under condition...
