Increasing evidence has demonstrated that aberrant forkhead box protein C1 (FOXC1) expression contributes to tumorigenesis in multiple types of malignant tumor. However, the clinical significance and biological roles of FOXC1 in cervical cancer remain unknown. The expression levels of FOXC1 were examined in human cervical cancer tissues and cells using reverse transcription‑quantitative polymerase chain reaction, immunohistochemistry and western blotting. Furthermore, high FOXC1 expression was significantly associated with advanced clinical stages, a high degree of malignancy and a poor outcome. FOXC1 silencing inhibited cell growth and enhanced cell apoptosis. Knockdown of FOXC1 markedly suppressed cell migration and invasion in vitro, and resulted in downregulation of phosphorylated‑RAC‑α serine/threonine‑protein kinase, proto‑oncogene c‑Myc and B‑cell lymphoma 2. In conclusion, these data indicated that upregulation of FOXC1 contributed to the development of cervical cancer by increasing the growth and motility of the cervical cancer cells, thereby worsening the disease progression in these patients.
越来越多的证据表明,叉头框蛋白 C1(FOXC1)表达异常促进多种恶性肿瘤的发生。然而,FOXC1 在宫颈癌中的临床意义和生物学作用尚不清楚。采用逆转录-定量聚合酶链反应、免疫组织化学和蛋白质印迹法检测人宫颈癌组织和细胞中 FOXC1 的表达水平。此外,FOXC1 高表达与临床分期较晚、恶性程度高和预后不良显著相关。FOXC1 沉默抑制细胞生长并促进细胞凋亡。体外敲低 FOXC1 显著抑制细胞迁移和侵袭,并导致磷酸化 Racα 丝氨酸/苏氨酸蛋白激酶、原癌基因 c-Myc 和 B 细胞淋巴瘤 2 的下调。综上所述,这些数据表明,FOXC1 的上调通过增加宫颈癌细胞的生长和运动能力,从而加重这些患者的疾病进展,促进宫颈癌的发生发展。
