Effect of Aqueous Extract of Trametes robiniophila on Proliferation of Human Prostate Cancer VCaP Cells
槐耳清膏在不同时间下对人前列腺癌VCaP细胞的增殖抑制作用。采用吖啶橙染色法分析槐耳清膏给药对VCaP细胞中自噬溶酶体形成的影响。借助蛋白免疫印迹法(Western blot)检测槐耳清膏给药后细胞中与自噬密切相关的蛋白微管相关蛋白Ⅰ轻链3(LC3),自噬相关蛋白3(Atg3),自噬相关蛋白5(Atg5),自噬相关蛋白7(Atg7)的表达。采用CCK-8法检测槐耳清膏与自噬抑制剂(Bafilomycin A

)联合给药及槐耳清膏单独给药对细胞增殖的作用。通过Western blot检测槐耳清膏对人前列腺癌VCaP细胞中Lamin B
(TRM,Huaier) on autophagy of human prostate cancer VCaP cells and Lamin B

expression, so as to uncover its role in the proliferation of VCaP cells.
Method

The inhibitory effect of 0, 2, 4, 6, 8, 10 g·L
-1
TRM aqueous extract on the proliferation of human prostate cancer VCaP cells at different time points were determined by cell counting kit-8 (CCK-8) assay. Acridine orange staining was conducted for analyzing the effect of TRM aqueous extract on the formation of autolysosomes in VCaP cells. After medication, the expression of microtubule-associated protein Ⅰ light chain 3 (LC3), autophagy-related protein 3 (Atg3), autophagy-related protein 5 (Atg5), and autophagy-related protein 7 (Atg7) in VCaP cells were detected by Western blot. The effect of TRM aqueous extract alone and its combination with autophagy inhibitor bafilomycin A
1
on the proliferation of VCaP cells were assayed by CCK-8 assay. RNA interference technology was used to explore the role of Lamin B
1
in anti-proliferation of VCaP cells by TRM.
Result
2
Compared with the blank group, TRM aqueous extract inhibited the proliferation of human prostate cancer VCaP cells in a time- and concentration-dependent manner (
P<
0.01). Acridine orange staining showed that TRM aqueous extract promoted the formation of autolysosomes in VCaP cells. As revealed by Western blotting, TRM aqueous extract up-regulated the expression levels of LC3-Ⅱ, Atg3, Atg5, and Atg7 in contrast to those in the blank group (
P
<
0.05). All these indicated that TRM aqueous extract induced the autophagy of VCaP cells. In addition, autophagy inhibition impaired the sensitivity of VCaP cells to TRM aqueous extract (
P
<
0.05). The comparison with the blank group showed that TRM aqueous extract inhibited Lamin B
1
protein expression in VCaP cells (
P
<
0.01), which in turns weakened the sensitivity of VCaP cells to TRM aqueous extract.
Conclusion
2
TRM aqueous extract inhibited the proliferation of human prostate cancer VCaP cells possibly by inducing autography and down-regulating Lamin B
1
expression. This study has provided a theoretical basis for the clinical application of TRM.
