MiR-144 regulates adipogenesis by mediating formation of C/EBPα-FOXO1 protein complex
CeRNA effect was an important regulation mode of miRNA mediated bio-activities, however, most of the researches of ceRNA were on ncRNAs synergetic with mRNAs, the exploration of ceRNA effect regulated mRNA interaction was still lack of. Besides, C/EBPα was one of the most crucial adipogenic regulators, which has been demonstrated to form a protein complex with FOXO1 to mediate AdipoQ expression. So that, we try to explore whether the ceRNA effect mediated the interaction of C/EBPα and FOXO1, and identified the key miRNAs of their ceRNA effect. In this paper, we found the ceRNA effect of C/EBPα and FOXO1 mediated their protein complex formation, furthermore regulated its transcriptional role for AdipoQ , thereby influencing pre-adipocytes adipogenesis . More importantly, we demonstrated that the miR-144 was the decisive factor that mediated the ceRNA effect of C/EBPα and FOXO1 to influence AdipoQ , thus regulated pre-adipocytes adipogenesis. This research will provide a new supplementary idea of the miRNA role in mediating coding RNA interaction that regulates pre-adipocyte adipogenesis.
