| 摘要: |
| 目的 研究竹黄颗粒干预IL-22/miR-330调控角质形成细胞增殖的分子机制。方法 IL-22处理HaCaT和HKCs细胞，应用QPCR技术检测细胞中miR-330的表达变化；之后慢病毒感染HaCaT和HKCs细胞，实现miR-330的过表达和干扰，通过CCK8和BrdU技术检测细胞增殖情况；采用CCK8、Western blot、QPCR、ELISA实验分别检测不同浓度竹黄颗粒处理HaCaT、HKCs后细胞增殖能力，IL-22蛋白表达水平，miR-330表达水平及细胞分泌IL-22含量的变化。结果 IL-22处理后的HaCaT和HKCs细胞中miR-330的表达水平显著下调（P<0.01），而细胞增殖能力显著提升（P<0.01）；过表达miR-330后HaCaT和HKCs细胞增殖能力显著下降（P<0.05），干扰miR-330后HaCaT和HKCs细胞增殖能力显著上升（P<0.05）；竹黄颗粒处理HaCaT、HKCs后，细胞增殖能力下降（P<0.01），IL-22蛋白表达水平显著下降（P<0.01），miR-330表达水平显著上升（P<0.01），细胞分泌IL-22含量显著下降（P<0.01）。结论 竹黄颗粒可以通过抑制IL-22的表达，促进miR-330的表达，从而抑制角质形成细胞增殖。 |

| Abstract: |
| Objective To study the molecular mechanism of IL-22/miR-330 intervened by Zhuhuang granule in regulating the proliferation of keratinocytes. Methods The expression of miR-330 in HaCaT and HKCs cells after IL-22 intervention was detected by QPCR technique. Overexpression and interference of miR-330 in HaCaT and HKCs cells were achieved by lentivirus infection, their cell proliferation was detected by CCK8 and BrdU. The cell proliferation ability, the expression of IL-22 protein, the expression level of miR-330 and the secretion of IL-22 in HaCaT and HKCs were determined by CCK8, Western blot, QPCR and ELISA, respectively. Results The expression of miR-330 in HaCaT and HKCs cells significantly decreased after treatment with IL-22 (P<0.01), and the cell proliferation ability of HaCaT and HKCs cells was significantly improved (P<0.01). The cell proliferation ability of HaCaT and HKCs cells significantly decreased after miR-330 overexpression (P<0.05). After interference of miR-330 expression, cell proliferation ability of HaCaT and HKCs had a significant increase (P<0.05). Cell proliferation ability of HaCaT and HKCs treated by different concentrations of Zhuhuang granule decreased (P<0.01). The expression of IL-22 protein decreased significantly (P<0.01), the expression level of miR-330 increased significantly (P<0.01), and the content of IL-22 decreased significantly (P<0.01). Conclusion Zhuhuang granule could inhibit the expression of IL-22, promote the expression of miR-330 and inhibit the proliferation of keratinocytes. |
