Cervical cancer is a common gynecological malignancy, accounting for 10% of all gynecological cancers. Recently, targeted therapy for cervical cancer has shown unprecedented advantages. Several studies have shown that ubiquitin conjugating enzyme E2 (UBE2C) is highly expressed in a series of tumors, and participates in the progression of these tumors. However, the possible impact of UBE2C on the progression of cervical squamous cell carcinoma (CESC) remains unclear. Here, we carried out tissue microarray analysis of paraffin-embedded tissues from 294 cervical cancer patients with FIGO/TNM cancer staging records. The results indicated that UBE2C was highly expressed in human CESC tissues and its expression was related to the clinical characteristics of CESC patients. Overexpression and knockdown of UBE2C enhanced and reduced cervical cancer cell proliferation, respectively, in vitro. Furthermore, in vivo experiments showed that UBE2C regulated the expression and activity of the mTOR/PI3K/AKT pathway. In summary, we confirmed that UBE2C is involved in the process of CESC and that UBE2C may represent a molecular target for CESC treatment.
宫颈癌是一种常见的妇科恶性肿瘤,占所有妇科癌症的10%。近年来,宫颈癌的靶向治疗显示出前所未有的优势。多项研究表明,泛素结合酶E2(UBE2C)在一系列肿瘤中高表达,并参与这些肿瘤的进展。然而,UBE2C对宫颈鳞状细胞癌(CESC)进展的可能影响仍不清楚。在此,我们对294例有FIGO/TNM癌症分期记录的宫颈癌患者的石蜡包埋组织进行了组织芯片分析。结果表明,UBE2C在人CESC组织中高表达,其表达与CESC患者的临床特征相关。UBE2C的过表达和敲低分别在体外增强和降低了宫颈癌细胞的增殖。此外,体内实验表明,UBE2C调节mTOR/PI3K/AKT通路的表达和活性。总之,我们证实UBE2C参与了CESC的进程,并且UBE2C可能是CESC治疗的一个分子靶点。
