摘要: |
目的 探讨菝葜皂苷元(sarsasapogenin,SAR)对人结直肠癌细胞HT-29增殖、凋亡和自噬的影响。方法 将HT-29细胞分为对照组(DMEM培养液)和SAR组(DMEM培养液+DMSO+10、20、30、40、50、60 mg/L SAR溶液);分别采用MTT法、流式细胞术、TUNEL染色及MDC染色检测细胞的增殖、凋亡及自噬的变化情况;用Western blot法检测细胞中Caspase-3、Caspase-9、Beclin-1及LC3B蛋白表达水平。结果 经SAR处理后,HT-29细胞的增殖能力明显降低(P<0.05),凋亡和自噬水平明显增加(P<0.05);与对照组相比,SAR组细胞Caspase-3、Caspase-9、Beclin-1及LC3B蛋白表达水平显著上调(P<0.05)。结论 SAR能够抑制结直肠癌细胞增殖,诱导细胞凋亡和细胞自噬的发生,其机制可能与上调Caspase-3、Caspase-9、Beclin-1及LC3B蛋白表达水平有关。 |

Abstract: |
Objective To investigate the effect of sarsasapogenin (SAR) on the proliferation, apoptosis, and autophagy of human colorectal cancer cell HT-29. Methods HT-29 cells were divided into control group (DMEM medium) and SAR group (DMEM medium + DMSO + 10, 20, 30, 40, 50, 60 mg/L SAR solution). MTT, flow cytometry, TUNEL staining, and MDC staining were used to detect the changes of cell proliferation, apoptosis and autophagy; Western blot method was used to detect the expression levels of Caspase-3, Caspase-9, Beclin-1 and LC3B protein. Results After treatment with SAR, the proliferation ability of HT-29 cells was significantly reduced (P<0.05), and the level of apoptosis and autophagy increased significantly (P<0.05). Compared with the control group, the expression levels of Caspase-3, Caspase-9, Beclin-1 and LC3B protein in SAR group were significantly increased (P<0.05). Conclusion SAR can inhibit the proliferation of colorectal cancer cells, induce apoptosis and autophagy. The mechanism may be related to the up-regulation of Caspase-3, Caspase-9, Beclin-1 and LC3B protein expression levels. |
