Abstract excerpt
BACKGROUND: As the main downstream effecter of tumor suppressor p53, p21(Waf1/Cip1) functions as a unique link from p53 to cell-cycle arrest and DNA repair. In contrast to p53, p21(Waf1/Cip1) has general rare mutations. The natural genetic variants of p21(Waf1/Cip1) have thus emerged for study to enhance understanding of interindividual differences in cancer risk. Two polymorphisms in the p21 ( Waf1/Cip1 ) gene,...
