CircRNA plays an important role in the development of tumors, but its mechanism of action in ovarian cancer is still unclear.
The expression level of hsa_circ_0013958 in 45 pairs of ovarian cancer tissues and cells was quantified by qRT-PCR, further revealing whether it is related to clinicopathological features and diagnostic value. Next, the effects of hsa_circ_0013958 on the proliferation, migration, invasion, and apoptosis of A2780 and OVCAR-3 cells were detected by CCK-8 assay, Transwell assay, and flow cytometry, respectively. Last, the expression levels of epithelial-mesenchymal transition-related proteins (E-cadherin and Vimentin) and apoptosis-related proteins (Bcl-2 and Bax) were detected by Western blotting.
Hsa_circ_0013958 was highly expressed in ovarian cancer tissues and cells, and its expression was closely related to patient FIGO stage and lymph node metastasis. Further, in vitro studies showed that knockdown of hsa_circ_0013958 suppressed proliferation, migration, and invasion of ovarian cancer cells but elevated the cell apoptotic rate. The expression levels of both epithelial-mesenchymal transition-related proteins and apoptosis-related proteins were also changed.
Hsa_circ_0013958 may contribute to the development of ovarian cancer by affecting epithelial-mesenchymal transition and apoptotic signaling pathways.
CircRNA 在肿瘤的发展中起着重要作用,但它在卵巢癌中的作用机制尚不清楚。
通过 qRT-PCR 定量检测 45 对卵巢癌组织和细胞中 hsa_circ_0013958 的表达水平,进一步揭示其是否与临床病理特征相关及具有诊断价值。接下来,通过 CCK-8 assay、Transwell assay 和流式细胞术分别检测 hsa_circ_0013958 对 A2780 和 OVCAR-3 细胞增殖、迁移、侵袭和凋亡的影响。最后,通过 Western blot 检测上皮-间质转化相关蛋白(E-钙黏蛋白和波形蛋白)和凋亡相关蛋白(Bcl-2 和 Bax)的表达水平。
hsa_circ_0013958 在卵巢癌组织和细胞中高表达,其表达与患者 FIGO 分期和淋巴结转移密切相关。进一步的体外研究表明,hsa_circ_0013958 的敲低抑制了卵巢癌细胞的增殖、迁移和侵袭,但提高了细胞凋亡率。上皮-间质转化相关蛋白和凋亡相关蛋白的表达水平也发生了变化。
hsa_circ_0013958 可能通过影响上皮-间质转化和凋亡信号通路促进卵巢癌的发展。
