Expression data from mouse primary brown preadipocytes

ABSTRACT: Brown adipocytes are specialized for heat generation and energy expenditure as a defense against cold and obesity. Recent studies demonstrate that brown adipocytes arise in vivo from a Myf5-positive, myoblastic progenitor by the action of PRDM16. Here, we identified a brown fat-enriched miRNA cluster mir-193b-365 as a key regulator of brown fat development. Blocking miR-193b and/or miR-365 in primary brown preadipocytes dramatically impaired brown adipocyte adipogenesis whereas myogenic markers were significantly induced. Forced expression of miR-193b and/or miR-365 in C2C12 myoblasts blocked the entire program of myogenesis, and miR-193b induced myoblasts to differentiate into brown adipocytes. Mir-193b-365 was upregulated by PRDM16. Our results demonstrate that mir-193b-365 serves as an
