MiR-1193 Inhibits the Malignancy of Cervical Cancer Cells by Targeting Claudin 7 (CLDN7)
OBJECTIVE: MicroRNAs (miRNAs) are highly involved in cancer development, including in cervical cancer (CC). In this study, we aimed to investigate the role and possible mechanism of a poorly studied miRNA, miR-1193, in CC progression. MATERIALS AND METHODS: Expression of miR-1193 was determined in 6...

description | OBJECTIVE: MicroRNAs (miRNAs) are highly involved in cancer development, including in cervical cancer (CC). In this study, we aimed to investigate the role and possible mechanism of a poorly studied miRNA, miR-1193, in CC progression. MATERIALS AND METHODS: Expression of miR-1193 was determined in 60 pairs of cervical samples. The impacts of miR-1193 on CC cell proliferation, invasion and migration capacities were verified by CCK-8, transwell and wound healing assays, respectively. Then, bioinformatics prediction, luciferase reporter assay, qRT-PCR and Western blot were successively conducted to study the targeting of claudin 7 (CLDN7) by miR-1193. After CLDN7 was restored in miR-1193-overexpressed cells, the rescue effects were determined. Finally, CLDN7 expression was analyzed in cervical samples, and its expression correlation with miR-1193 was explored. RESULTS: Compared with paired normal tissues, miR-1193 was sharply decreased in abnormal tissues (intraepithelial lesions and cancerous tissues). Especially, miR-1193 expression was gradually decreased in low-grade squamous intraepithelial lesions, high-grade squamous intraepithelial lesions and CC. Enforced expression of miR-1193 inhibited CC cell proliferation, invasion and migration. Mechanistically, we confirmed CLDN7 as a target of miR-1193, and restoration of CLDN7 robustly rescued the tumor suppressing effects of miR-1193 in CC cells. CLDN7 was upregulated in abnormal cervical tissues and its expression exhibited inverse correlation with that of miR-1193 in CC. CONCLUSION: Our results suggested that miR-1193 exerted tumor inhibitory roles in CC malignancy by directly targeting CLDN7. |
