ABSTRACT
Objective To study the pinoresinol diglucoside (PDG) on gene regulation role of ESF-1 cells in collagen secretion, to reveal PDG repair mechanisms on scalded skin.Methods The cells cultured in vitro were divided into the control group, the estradiol group and the three different PDG doses groups. The concentration of the high, medium and low dose groups were 100, 10, 1μmol/L, and that of estradiol group were 10-3μmol/L. The activity of proliferation was detected by MTT. Then collagen type I (Col I), collagen typeⅢ (ColⅢ), tissue inhibitors of metalloproteinase 1 (TIMP-1), tissue inhibitors of metalloproteinase 2 (TIMP-2) and matrix metalloproteinase 1 (MMP-1) expression levels of mRNA after administration of cells were detected by RT-PCR.Results Compared with the control group, the proliferation of ESF-1 cells (0.559 ± 0.027, 0.552 ± 0.034vs. 0.489 ± 0.027,P<0.05) in the estradiol and medium-dose PDG was significantly higher. The expression level of mRNA of ColⅠ(0.958 ± 0.021, 0.929 ± 0.031, 0.916 ± 0.015vs. 0.844 ± 0.022), ColⅢ (0.783 ± 0.038, 0.918 ± 0.021, 0.855 ± 0.017vs. 0.678 ± 0.024), TIMP-1 (0.939 ± 0.025, 0.889 ± 0.036, 0.853 ±  0.015 vs. 0.780 ± 0.023), TIMP-2 (0.507 ± 0.024, 0.655 ± 0.037, 0.572 ± 0.025vs. 0.405 ± 0.062) in the estradiol, low-, medium-dose PDG groups were significantly higher than those in the control group (P<0.05 or P<0.01). Besides, the MMP-1 (0.343 ± 0.038, 0.407 ± 0.046, 0.435 ± 0.037vs.0.519 ± 0.041) mRNA expression level in the middle and low dose PDG groups significantly decrease (P<0.05 orP<0.01). Conclusions The PDG could enhance the activity of ESF-1 cell proliferation, increase the expression of related collagen and tissue inhibitor of metalloproteinases and inhibit that of matrix metalloproteinases to repair scalded skin.
