Methods: 3 T3 L1 adipocyte cells were used to investigate gene expression of PPARy reverse transcription-polymerase chain reaction method. The γ and GLUT4 protein b adipocyte cells were differentiated by using insulin, dexamethasone and 3-isobutyl-1-methylxanthine from 3 T3-L1 cells. Pioglitazone, AHF, CHF and the combination of both herbs were evaluated on glucose uptake activity, PPAR γ and GLUT4 mRNA expressions in 3 T3-L1 adipocyte. Results: The results showed that combination of AHF at 30 μg/mL and CHF at 10 μg/mL could enhance insulin-stimulated glucose uptake. The combination also increased PPAR γ and GLUT4 mR NA expressions significantly in comparison to those of negative control(DMSO). These effects were equal in comparison to those of pioglitazone(0.02 μM) and its single extracts Conclusions: The combination of AHF and CHF can increase glucose uptake and insulin sensitivity through up-regulation of PPAR γ and GLUT4 mRNA expressions in 3 T3-L1 adipocyte.展开更多
