Bcl-2 Protein Targeting by the p53/p21 Complex—Letter

Kim and colleagues reported a p53/p21 complex regulates cancer cell invasion and apoptosis by targeting the Bcl-2 family ([1][1]). Interaction of overexpressed p53 and p21 proteins in p53-null H1299 cells correlated with decreased cell invasion. No coimmunoprecipitation experiments documenting
