Cervical cancer is the fourth most common female malignancy for both incidence and mortality worldwide and is one of the major threats to women's health. The role of long non‑coding RNAs (lncRNAs) in cervical cancer remains largely unknown. In the present study, the differentially expressed lncRNAs in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) tissues were retrieved form The Cancer Genome Atlas (TCGA) and were analyzed. The expression analysis of related genes was performed with GEPIA. The proliferation and migratory and invasive abilities of MIR205HG knockdown CESC cells were analyzed using Cell Counting Kit‑8 and transwell assays. The expression of Ki‑67 and p16 was detected by immunofluorescence. A total of 203 differentially expressed lncRNAs were identified. The results demonstrated that MIR205HG was overexpressed in CESC tissues. Furthermore, the genes related to MIR205HG were enriched in cancer‑related pathways. MIR205HG knockdown significantly decreased the proliferation and migratory and invasive abilities of CESC cells. In addition, silencing of MIR205HG significantly decreased the expression of p16 in C‑33 A cells. The expression of fibroblast growth factor receptor 3, thymidine phosphorylase and GTPase HRas was downregulated in MIR205HG knockdown CESC cells. These findings revealed some potential lncRNA candidates for cervical cancer research and suggested that MIR205HG may have a pro‑tumor role in CESC.
宫颈癌是全球女性发病率和死亡率第四高的常见恶性肿瘤,也是威胁女性健康的主要因素之一。长链非编码 RNA(lncRNA)在宫颈癌中的作用尚不清楚。本研究从癌症基因组图谱(TCGA)中检索了宫颈鳞状细胞癌和宫颈内膜腺癌(CESC)组织中差异表达的 lncRNA,并进行了分析。使用 GEPIA 进行了相关基因的表达分析。通过细胞计数试剂盒-8 和 Transwell 分析检测 MIR205HG 敲低的 CESC 细胞的增殖、迁移和侵袭能力。通过免疫荧光检测 Ki-67 和 p16 的表达。共鉴定出 203 个差异表达的 lncRNA。结果表明,MIR205HG 在 CESC 组织中高表达。此外,与 MIR205HG 相关的基因富集在癌症相关途径中。MIR205HG 敲低显著降低了 CESC 细胞的增殖、迁移和侵袭能力。此外,沉默 MIR205HG 显著降低了 C-33A 细胞中 p16 的表达。MIR205HG 敲低的 CESC 细胞中纤维母细胞生长因子受体 3、胸苷磷酸化酶和 GTPase HRas 的表达下调。这些发现揭示了一些潜在的 lncRNA 候选物用于宫颈癌研究,并表明 MIR205HG 在 CESC 中可能具有促肿瘤作用。
