Key result
Knockdown of ANGPTL4 in 3T3-L1 preadipocytes did not block differentiation but reduced LPL expression, suggesting ANGPTL4 and LPL may form a regulatory pathway.
Why the study?
To explore how ANGPTL4 influences lipid metabolism by observing changes in key gene expression before and after inhibiting ANGPTL4 during preadipocyte differentiation.
Knockdown of ANGPTL4 in 3T3-L1 preadipocytes alters the expression of lipid metabolism genes, specifically showing a similar expression pattern to LPL, suggesting they may form a regulatory pathway.
Does not support clinical translation; leaves open whether the ANGPTL4-LPL pathway influences cardiometabolic outcomes in vivo.
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.

Zhao et al. (2021) studied Adipocyte differentiation. ANGPTL4 knockdown via siRNA vs. Negative control siRNA was evaluated on Expression of LPL and other lipid metabolism genes. Knockdown of ANGPTL4 in 3T3-L1 preadipocytes did not block differentiation but reduced LPL expression, suggesting ANGPTL4 and LPL may form a regulatory pathway.
