ABSTRACT
Objective To explore the mechanism and regulative function of betulin on anti-aging genes related of normol human dermal fibroblasts (ESF-1), and to reveal the repairing mechanism of betulin on wrinkles. Methods The cultured cell in vitro were divided into the control group, the estradiol group and the betulin high, medium and low dose groups. Competence of ESF-1 cells was detected by MTT. Expression of mRNA of collagen type I and Ⅲ (ColⅠand Col Ⅲ), tissue inhibitors of matrix metalloproteinase 1 and 2 (TIMP-1 and TIMP-2), matrix metalloproteinase 1 (MMP-1) was detected by RT-PCR. Results Compared with the control group, the proliferation of ESF-1 cells (0.455 ± 0.037, 0.445 ± 0.040 vs. 0.385 ± 0.601) in the estradiol group and the medial-dose betulin group were increased (P<0.05). Compared with the control group, the expression of mRNA of ColⅠ (0.960 ± 0.012, 0.929 ± 0.015 vs. 0.842 ± 0.014), Col Ⅲ (0.892 ± 0.009, 0.824 ± 0.022 vs. 0.768 ± 0.025), TIMP-1 (0.938 ± 0.026, 0.878 ± 0.035 vs. 0.796 ± 0.022), TIMP-2 (0.557 ± 0.025, 0.506 ± 0.036 vs. 0.436 ± 0.063) in the estradiol group and the medial-dose betulin group were increased (all P<0.01). Conclusion Betulin based on increasing the competence of ESF-1 cells, promoting collagen synthesis and the expression level of related-proteinase is to suspend the development of wrinkles.
