Adipocyte differentiation involves a temporally regulation set of gene-expression events, such as peroxisome proliferator activated receptor-γ (PPARγ) and GATA binding protein-3 (GATA-3). In our investigation, we found cytopiloyne (CP), a phytocompound from Bidens pilosa, can reduce the differentiation of adipocytes from various animal sources. We also proved CP inhibits adipocyte differentiation through the GATA-3 pathway in 3T3-L1 cells. Our previous results showed CP can regulate the expression of PKCα translocation in RAW264.7 macrophages and RIN-m5F β-cells. Recent papers indicated that the expression of PKCα and calreticulin (CRT), the major Ca2+-binding protein, can regulate the adipogenesis in 3T3-L1 cells. Therefore, we will focus the adipogenic effect of CP on interaction among PKCα, CRT and Ca2+.
