Impairment of the DNA Repair and Growth Arrest Pathways by p53R2 Silencing Enhances DNA Damage–Induced Apoptosis in a p53-Dependent Manner in Prostate Cancer Cells

1 May 2008

Abstract excerpt

p53R2 is a p53-inducible ribonucleotide reductase that contributes to DNA repair by supplying deoxynucleotide triphosphate pools in response to DNA damage. In this study, we found that p53R2 was overexpressed in prostate tumor cell lines compared with immortalized prostatic epithelial cells and that the protein was induced upon DNA damage. We investigated the effects of p53R2 silencing on DNA damage in LNCaP...
