摘要: 目的 探究核前体mRNA结构域调控蛋白1B(RPRD1B)在人卵巢癌中的作用。方法 利用RT-qPCR和Western blot实验检测卵巢癌中RPRD1B的表达水平。基于CRISPR/Cas9及慢病毒系统构建RPRD1B敲除和过表达细胞系A2780和SKOV3,利用划痕、Transwell实验以及小鼠皮下成瘤模型验证其在卵巢癌中的功能。结果 RPRD1B在卵巢癌中高表达(P<0.001)。敲除RPRD1B抑制卵巢癌细胞集落形成和增殖能力(P<0.001),以及细胞迁移(P<0.05)和侵袭能力(P<0.001)。同时,敲除RPRD1B抑制SKOV3卵巢癌细胞在小鼠体内成瘤能力(P<0.001)。结论 RPRD1B在多个人卵巢癌细胞系中高表达,并促进小鼠皮下肿瘤生长。

Abstract: Objective To explore the role of regulation of nuclear pre-mRNA-domain-containing 1B(RPRD1B)in human ovarian cancer. Methods The expression level of RPRD1B in ovarian cancer was detected by RT-qPCR and Western blot experiments. Based on the CRISPR/Cas9 system and lentiviral system, the A2780 and SKOV3 cell lines with RPRD1B gene knockout and over-expression were respectively constructed, and their functions in ovarian cancer were verified by wound-healing assay, Transwell assay and mouse subcutaneous tumor formation model. Results RPRD1B was highly expressed in ovarian cancer cell lines (P<0.001). Knockout of RPRD1B inhibited the colony formation and proliferation ability of ovarian cancer cells (P<0.001), as well as the cell migration (P<0.05) and invasion ability (P<0.001). Meanwhile, knockout of RPRD1B inhibited the tumorigenesis ability of SKOV3 ovarian cancer cell lines in vivo (P<0.001). Conclusions RPRD1B is highly expressed in human ovarian cancer cell lines and promotes the growth of subcutaneous tumors in mice.

Key words: regulation of nuclear pre-mRNA-domain-containing 1B (RPRD1B), ovarian cancer, proliferation
