Abstract (original English)
Adipocytokines, bioactive molecules secreted from adipose tissues, play important roles in physiology, development, and disease. Recently, heparin-binding epidermal growth factor-like growth factor (HB-EGF) was identified as an adipocytokine whose expression correlates with obesity. However, the biological role of fat-secreted HB-EGF is still unclear. In this study, we investigated the effects of HB-EGF on the adipocyte differentiation of C3H10T1/2 pluripotent mesenchymal cells. Upon adipogenic conversion of C3H10T1/2 cells, HB-EGF displayed dynamic changes in expression where an initial decrease was followed by increased levels of expression at later stages. HB-EGF treatment during adipogenic induction inhibited lipid accumulation and decreased the expression of adipocyte molecular markers (fatty acid-binding protein, peroxisome proliferator-activated receptor gamma, and CAAT enhancer-binding protein alpha) and lipogenic genes (glucose transporter, fatty acid synthetase, and lipoprotein lipase). Therefore, HB-EGF has an inhibitory effect on adipocyte differentiation. Administration of HB-EGF at various intervals during adipocyte differentiation revealed that HB-EGF acts during the early stages of adipocyte differentiation, but not at the later stages of differentiation. Furthermore, HB-EGF was able to block the commitment of pluripotent mesenchymal cells to the adipocyte linea
