[Regulative effect of bakuchiol on ESF-1 cells anti-aging gene]
Objective:
To explore the mechanism of bakuchiol on anti-aging gene mRNA expression level of human skin fibroblasts (ESF-1).
Methods:
The potential of cell proliferation which was divided into blank group,positive control estradiol group, and bakuchiol high, medium and low dose groups was detected by MTT. The expression levels of Col I, Col III, TIMP-1, TIMP-2 and MMP-1 mRNA were detected with RT-PCR.
Results:
ESF-1 vitality and the expression levels of Col I, Col III, TIMP-1 and TIMP-2 mRNA were significantly increased by bakuchiol and E2. However, the expression of MMP-1 mRNA was reduced by bakuchiol and E2.
Conclusion:
The bakuchiol can enhance ESF-1 cell activity, promote collagen and matrix metalloproteinase inhibitors mRNA expression level and inhibit mRNA expression of matrix metalloproteinases in order to postpone skin aging.
