Abstract

Adipose tissue is a complex, highly metabolically active tissue. The expansion of adipose tissue is mainly affected by two processes: the number of adipocytes and the change of adipocyte size. Adipocyte differentiation is regulated by multiple factors. 3T3-L1 preadipocyte line has become the most widely studied cell line for adipocyte proliferation, differentiation and regulation of related genes. In our previous study, we found that ANGPTL4 was related to preadipocyte differentiation through PPAR signaling pathway. Recent studies have shown that ANGPTL4 has functions of regulating oncogenesis, vascular permeability, glucose homeostasis, lipid metabolism, energy homeostasis. In this study, we observed the changes of key genes expression before and after inhibiting ANGPTL4 to explore how ANGPTL4 influence on lipid metabolism. Results shows that, ANGPTL4 and LPL have similar expression pattern. We suspect that, ANGPTL4 and LPL may form a pathway, when ANGPTL4 is suppressed it may block the pathway and inhibit LPL.
