"WebMdm2 is the main cellular antagonist of p53, as evidence by the observations that mdm2 knockout mice embryo die early unless p53 is inactivated as well (Jones et al., 1995; Montes de Oca Luna et al., 1995). Thus, down-regulation of mdm2 and inhibition of the mdm2/p53 interaction have been proposed for the treatment of tumors with wild-type p53. " - Neogenomics mdm2 fish
