MicroRNAs of miR-34 family have been originally identified as direct transactivation target of p53 and are putative tumor suppressors. Surprisingly, mice lacking all mir-34 genes show no increase in cancer formation by 18 months of age, hence placing in doubt physiological relevance of previous studies. Here we report that mice with prostate epithelium-specific inactivation of mir-34 and p53 show expansion of prostate stem cell compartment, and develop early invasive adenocarcinomas and high-grade prostatic intraepithelial neoplasia, whereas no such lesions are observed after inactivation of mir-34 or p53 genes alone by 15 months of age. Consistently, combined deficiency for p53 and miR-34 leads to acceleration of MET-dependent growth, self-renewal, and motility of prostate stem/progenitor cells. Our study provides direct genetic evidence that mir-34 genes are bona fide tumor suppressors, and identifies p53/miR-34 joint control of MET expression as a key component of prostate stem cell compartment regulation, aberrations of which may lead to cancer.
