Gastric carcinoma proliferation enhancing transcript 1 (GHET1) has been suggested to serve as a promising oncogenic lncRNA in various types of human cancer. However, the role of GHET1 remained unknown in cervical cancer. In our study, we found GHET1 expression was markedly elevated in cervical cancer tissue specimens and cell lines compared with adjacent normal cervical tissue specimens and human normal cervical cell line, respectively. Then, we found high expression of GHET1 is a useful biomarker to discriminate cervical cancer tissues from non-tumorous tissues, and associated with advanced clinical stage, lymph node metastasis, distant metastasis and poor histological grade in cervical cancer patients. The survival analysis showed high GHET1 expression was an independent unfavorable prognostic factor in cervical cancer patients. Knockdown of GHET1 expression markedly inhibits cervical cancer cell proliferation, migration, and invasion. The loss-of-function study indicated knockdown of GHET1 expression markedly inhibits cervical cancer cell proliferation, migration, and invasion. In conclusion, GHET1 acts as an oncogenic lncRNA in cervical cancer.
胃腺癌增殖增强转录本 1(GHET1)已被认为是多种人类癌症中一种有前途的致癌 lncRNA。然而,GHET1 在宫颈癌中的作用尚不清楚。在我们的研究中,我们发现与相邻的正常宫颈组织标本和人正常宫颈细胞系相比,GHET1 在宫颈癌组织标本和细胞系中的表达明显升高。然后,我们发现 GHET1 的高表达是区分宫颈癌组织与非肿瘤组织的有用生物标志物,并且与宫颈癌患者的晚期临床分期、淋巴结转移、远处转移和不良组织学分级相关。生存分析显示,GHET1 高表达是宫颈癌患者的独立不良预后因素。敲低 GHET1 的表达显著抑制宫颈癌细胞的增殖、迁移和侵袭。功能丧失研究表明,敲低 GHET1 的表达显著抑制宫颈癌细胞的增殖、迁移和侵袭。总之,GHET1 在宫颈癌中作为一种致癌 lncRNA 发挥作用。
