Expression data from miR-203 induction in mouse skin

We identify numerous miR-203 in vivo targets that are highly enriched for the promotion of cell cycle and cell division. Importantly, individual targets including p63, Skp2 and Msi2 play distinct roles downstream of miR-203 to regulate the cell cycle and long-term proliferation. Together, our findings reveal rapid and widespread impact of miR-203 on the self-renewal program during the epidermal differentiation and provide mechanistic insights for the potent role of miR-203 where coordinated repression of multiple targets is required for the function of this miRNA.
