摘　　要：目的:探讨下调DEAD-box解旋酶1(DDX1)基因对宫颈鳞癌Si Ha细胞增殖、凋亡、转移及侵袭能力的影响。方法:si RNA转染构建DDX1低表达Si Ha细胞系、和阴性对照组,用RT-qPCR和Westem Blot检测DDX1的m RNA和蛋白表达水平。应用CCK8法、流式细胞技术、Transwell实验分别检测DDX1低表达对Si Ha细胞增殖、凋亡、转移和侵袭能力的影响。结果:(1)m RNA水平检测显示:下调DDX1,Si-DDX1组中DDX1表达均低于Si-NC组,差异有统计学意义(P<0.05)。蛋白水平检测显示,Si-DDX1组中DDX1表达低于Si-NC组,差异有统计学意义(P<0.05)。(2)下调DDX1后,Si-DDX1组细胞的增殖活性较Si-NC组升高,Si-DDX1组的凋亡率较Si-NC组降低,差异有统计学意义(P<0.05)。(3)下调DDX1后,Si-DDX1组细胞转移率和侵袭率均较Si-NC组增高,差异有统计学意义(P<0.05)。结论:DDX1的表达受到抑制后,宫颈鳞癌Si Ha细胞的增殖能力增强、凋亡能力减弱,转移和侵袭能力增强。Objective:To investigate the impact of downregulating DDX1 gene on growth,apoptosis,metastasis,and invasion of SiHa cells in cervical cancer.Methods:A DDX1-low-expression SiHa cell line was established via siRNA transfection,alongside a negative control group.The mRNA and protein expression levels of DDX1 were assessed using RT-qPCR and Western Blot analysis,respectively.Additionally,CCK8 assay,flow cytometry analysis,and Transwell assay were conducted to evaluate the effect of decreased DDX1 expression on proliferation,apoptosis,metastasis,and invasion of SiHa cells.Results:(1)Analysis of mRNA levels revealed significantly lower expression of DDX1 in the Si-DDX1 group compared to the Si-NC group(P<0.05).Similarly,analysis at the protein level demonstrated a statistically significant decrease in DDX1 expression in the Si-DDX1 group compared to the Si-NC group(P<0.05).(2)Down-regulation of DDX1 resulted in increased cellular proliferation activity in the Si-DDX1 group compared to the Si-NC group(P<0.05),while exhibiting a lower rate of apoptosis(P<0.05).(3)Decreased expression of DDX1 led to higher rates of metastasis and invasion in the Si-DDX1 group compared to the Si-NC group with statistical significance(P<0.05).Conclusions:Inhibition or reduction of DDX1 expression enhances cellular proliferation ability while weakening apoptotic capability;additionally promoting metastatic potential and invasive abilities within SiHa cells.
