摘要: 目的

观察黄芪注射液对人角质细胞(KC)增殖与黏附因子β-连环蛋白(β-catenin)表达的影响,探讨黄芪注射液对银屑病治疗作用的可能机制。

方法

增殖功能实验,将添加不同浓度黄芪注射液的HaCaT细胞作为实验组,不添加药物的HaCaT细胞作为对照组,同时设无细胞、无药物的空白组。采用细胞计数法确定黄芪注射液作用有效浓度,2倍梯度稀释不同浓度黄芪注射液加入实验组HaCaT细胞中孵育24、48和72 h,采用CCK-8法检测各组细胞增殖率。黏附功能实验,实验组为加入1.0 g·L-1黄芪注射液的HaCaT细胞,对照组为不加入黄芪注射液的HaCaT细胞。细胞培养24和48 h后,定量聚合酶链反应(qPCR)法检测2组细胞中β-catenin mRNA表达水平;HaCaT细胞培养48 h后,Western blotting法检测2组细胞中β-catenin蛋白表达水平。

结果

增殖功能实验,与0、0.01和0.10 g·L-1黄芪注射液组比较,培养24和48 h后1.0 g·L-1黄芪注射液组HaCaT细胞增殖率降低(P<0.01);2倍浓度梯度稀释黄芪注射液(0、0.5、1.0、2.0、4.0、8.0和16.0 g·L-1)与HaCaT细胞孵育24、48和72 h后,与对照组比较,作用24和48 h时1.0 g·L-1黄芪注射液组HaCaT细胞增殖率降低(P<0.05),72 h细胞增殖率升高(P<0.05)。黏附功能实验,与0 g·L-1黄芪注射液组比较,作用24 h后1.0 g·L-1黄芪注射液组HaCaT细胞中β-catenin mRNA表达水平差异无统计学意义(P>0.05),作用48 h后1.0 g·L-1黄芪注射液组HaCaT细胞中β-catenin蛋白表达水平明显降低(P<0.01)。

结论

黄芪注射液对银屑病的治疗作用机制可能与抑制人角质细胞的增殖、抑制黏附因子β-catenin蛋白表达有关联。黄芪注射液作为单一的因素可以抑制HaCaT细胞增殖并下调β-catenin蛋白表达,该抑制效应可能随时间衰减。

Abstract: Objective

To observe the effects of Astragalus Injection on the proliferation of human keratinocytes(KC) and the expression of adhesion factor β-catenin, and to explore the possible mechanism of Astragalus Injection in the treatment of psoriasis.

Methods

The HaCaT cells were collected. In the proliferation function experiment, the HaCaT cells were divided into experimental groups (added with different concentrations of Astragalus Injection) and control group (without drugs), at the same time, blank group (without drugs and cells) was set up. The effective concentration of Astragalus Injection was determined by cell counting method.The HaCaT cells in experimental groups were incubated for 24, 48 and 72 h after adding different concentrations of Astragalus Injection with two times gradient dilution, and the proliferation rates of HaCaT cells in various groups were detected by CCK-8 method. In the adhesion function experiment, the HaCaT cells in experimental group were treated with 1.0 g·L-1 Astragalus Injection and the HaCaT cells in control group were not treated with Astragalus Injection. After cultured for 24 and 48 h, the expression levels of β- catenin mRNA in the HaCaT cells in two groups were detected by qPCR method; after cultured for 48 h, the expression levels of β-catenin protein in the HaCaT cells in two groups were detected by Western blotting method.

Results

The proliferation function test results showed that compared with 0,0.01, and 0.10 g·L-1 Astragalus Injection groups,the proliferation rates of the HaCaT cells in 1.0 g·L-1 Astragalus Injection group were decreased after treated for 24 and 48 h (P<0.01). The HaCaT cells were incubated with 2 times concentration gradient dilution of Astragalus Injection ( 0, 0.5, 1.0, 2.0, 4.0, 8.0, 16.0 g·L-1)for 24, 48, and 72 h, compared with control group, the proliferation rates of HaCaT cells in 1.0 g·L-1 Astragalus Injection group were decreased after treated for 24 and 48 h (P<0.05), the proliferation rate of HaCaT cells was increased after treated for 72 h(P<0.05). In the adhesion function experiment, compared with 0 g·L-1 Astragalus Injection group, there was no significant difference in the expression level of β-catenin mRNA in the HaCaT cells in 1.0 g·L-1 Astragalus Injection group after treated for 24 h (P>0.05);after treated for 48 h, the expression level of β-catenin protein in the HaCaT cells in 1.0 g·L-1 Astragalus Injection group was decreased significantly (P<0.01).

Conclusion

The mechanism of Astragalus injection in the treatment of psoriasis may be related to the inhibition of proliferation of human KC and the expression of adhesion factor β-catenin. As a single factor, Astragalus Injection could inhibit the proliferation of HaCaT cells and reduce the expression of β-catenin protein,and the inhibitory effect may decrease with the prolongation of time.
