Effect of compound poria prescription on proliferation and differentiation and expression of PPAR? mRNA in rat preadipocytes / 中国病理生理杂志

ABSTRACT

AIM: To study the effect of herbal compound poria prescription (CPP) on proliferation and differentiation in primary rat preadipocytes, and to explore the mechanism of this process. METHODS: Primary cultured rat preadipocyte proliferation was determined by cell counting and MTT spectrophotometry. Cell differentiation was determined by Oil Red O staining, and the expression of PPAR? mRNA was determined by RT-PCR. RESULTS: CPP inhibited the proliferation and differentiation of primary rat preadipocytes in a dose-dependent manner, and it also inhibited the expression of PPAR? mRNA. CONCLUSION: CPP inhibits the proliferation of primary rat preadipocytes and inhibits the preadipocyte differentiation by suppressing the expression of PPAR? mRNA.
