The tumor suppressor p53 is central to many cellular stress responses. Although numerous protein factors that control p53 have been identified, the role of microRNAs (miRNAs) in regulating p53 remains unexplored. In a screen for miRNAs that modulate p53 activity, we find that miR-29 family members (miR-29a, miR-29b and miR-29c) upregulate p53 levels and induce apoptosis in a p53-dependent manner. We further find that miR-29 family members directly suppress p85 alpha (the regulatory subunit of PI3 kinase) and CDC42 (a Rho family GTPase), both of which negatively regulate p53. Our findings provide new insights into the role of miRNAs in the p53 pathway.

MicroRNAs comprise a class of small ( approximately 22 nucleotide) non-coding RNA species and they bind to their complementary sequence on the 3'UTR of target genes and cause translational repression. In the present study, we report that miR-29a levels are significantly elevated in the diabetic db/db mice liver. Further, we report the effects of such elevation on insulin action in HepG2 cells. Overexpression of miR-29a narrowed down insulin mediated Akt phosphorylation without altering the total Akt levels presumably due to another upstream mediator being directly targeted by miR-29a. This hunt led us to the discovery that the p85alpha subunit of PI3K (phosphoionositide-3-kinase), the upstream molecule in the insulin signaling cascade harbors the miR-29a binding site on its 3'UTR and a marked inhibition of PI3Kp85alpha was observed by this microRNA. This was consequently accompanied by attenuation of insulin inhibition of PEPCK gene expression. All these events could be significantly prevented in the presence of the miR-29a inhibitor. Our results, for the first time, show the effect of miR-29a in counteracting insulin action on PEPCK gene expression by primarily targeting PI3K and abrogating downstream insulin signaling in HepG2 cells.
