Promotion of white adipose tissue beiging has received considerable attention due to possible usefulness for preventing obesity and the comorbidities. Licarin A (LA) is a compound derived from Mexican medicinal plant Aristolochia taliscana. Here, we report that LA stimulates the development of brown-like and beige-like adipocytes from C3H10T1/2 mesenchymal stem cells with phenotypic shifts to formation of smaller lipid droplets. LA also markedly induced the expression of proteins characteristic of brown-like adipocytes in C3H10T1/2 mesenchymal stem cells. LA induced uncoupling protein 1 (Ucp1) and expression of other thermogenic genes in C3H10T1/2 mesenchymal stem cells via a mechanism involving protein kinase A (PKA). LA treatment also inhibited expression of white-adipocyte specific genes. Moreover, LA treatment promoted lipolysis via PICA mediated pathway. Our findings inaugurate a new role of LA as an inducer of brown-like adipocytes formation with lipolytic properties, which in future might be studied in vivo as a potential anti-obesity agent. 收起
