Adipogenic differentiation of preadipocytes is a complex process regulated by various factors including miRNAs and cytokines. MiR-143 is a well known miRNA that enhances adipogenesis. Pleiotrophin (PTN), a heparin-binding growth factor, plays a negative role in adipogenesis. In this investigation, we demonstrate that PTN is a target gene of miR-143 during adipogenic differentiation in 3T3-L1 preadipocytes...
Pleiotrophin (PTN) plays diverse roles in cell growth and differentiation. In this investigation, we demonstrate that PTN plays a negative role in adipogensis and that glycogen synthase kinase 3β (GSK-3β) and β-catenin are involved in the regulation of PTN-mediated preadipocyte differentiation. Knocking down the expression of PTN using siRNA resulted in an increase in phospho-GSK-3β expression, and...
