BMP4 has been shown to induce C3H10T1/2 pluripotent stem cells to commit to adipocyte lineage. In addition to several proteins identified, microRNAs also play a critical role in the process. In this study, we identified microRNA-140 (miR-140) as a direct downstream component of the BMP4 signaling pathway during the commitment of C3H10T1/2 cells to adipocyte lineage. Overexpression of miR-140 in C3H10T1/2 cells promoted commitment, whereas knockdown of its expression led to impairment. Additional studies indicated that Ostm1 is a bona fide target of miR-140, which is significantly decreased during commitment, and Ostm1 was also demonstrated to function as an anti-adipogenic factor.
