Abstract:
Objective To investigate the effects and possible mechanism of electret and 5-fluorouracil(5-FU)on the growth of scar fibroblasts.Methods The effect of+5000 V electret combined with different concentrations of 5-FU on the proliferation of scar fibroblasts was detected by automatic enzyme labeling instrument.The apoptosis of scar fibroblasts and the mRNA expression of p53 and other apoptotic genes were studied by fluorescence microscopy and RT-PCR technology under the action of electrostatic field.Results ① After the treatment of positive electret and different concentrations of 5-FU for 72 h,the cell proliferation rate decreased,and the inhibition rate of scar cells in the+5000 V electret+160 μg/ml 5-FU group was(0.15±0.051)%.②+5000 V electret group could promote the apoptosis of scar fibroblasts;The number of apoptotic cells in+5000 V electret and 5-FU group was higher than that in 5-FU group.③The mRNA expression levels of four apoptotic genes in the+5000 V electret group were increased,and the expression levels of four signature genes in the+5000 V electret and 5-FU group were increased compared with those in the 5-FU group.Conclusion The combination of positive electret and 5-FU had a synergistic effect on inhibiting cell growth.The mechanism of positive electret inhibiting scar cell growth may be through promoting the expression of apoptosis gene,and then affecting the growth state of cells to inhibit cell growth.
