[Effects of Pollen Typhae total flavones on mRNA expressions of peroxisome proliferator-activated receptors in 3T3-L1 adipocytes].

Objective: To explore the effects of Pollen Typhae total flavones (PTF) on the mRNA expressions of peroxisome proliferator-activated receptors (PPARs) alpha,gamma, beta/delta so as to analyze its possible mechanism in improving the insulin sensitivity of 3T3-L1 adipocytes.

Methods: Adipocytes were treated with PTF, and expressions of PPARalpha, PPARgamma, PPARbeta/delta mRNAs relating to the adipocyte glucose and lipid metabolism were determined by reverse transcription polymerase chain reaction.

Results: PTF obviously up-regulated the expressions of PPARalpha and PPARgamma mRNAs, all showing significant differences as compared with those in the normal control group (P<0.01).

Conclusion: With its function as an insulin sensitizer, PTF may enhance the PPARalpha and PPARgamma mRNA expressions in 3T3-L1 adipocytes.
