Circ-ABCB10 knockdown inhibits the malignant progression of cervical cancer through microRNA-128-3p/ZEB1 axis
AIMS: We focused on the detailed functions of circ-ABCB10 in cervical cancer (CC) development and its mechanisms. BACKGROUND: The increasing findings have proposed the central roles of circular RNAs (circRNAs) in the tumorigenesis of various human cancers. Circ-ABCB10 displays promising oncogenic ef...

description | AIMS: We focused on the detailed functions of circ-ABCB10 in cervical cancer (CC) development and its mechanisms. BACKGROUND: The increasing findings have proposed the central roles of circular RNAs (circRNAs) in the tumorigenesis of various human cancers. Circ-ABCB10 displays promising oncogenic effect in several tumors. METHODS: Circ-ABCB10 and miR-128-3p production levels in CC tissues and cells were tested through RT-qPCR. The association of circ-ABCB10 expression with clinicopathologic parameters of CC patients was statistically analyzed. Cell proliferation, invasion, apoptosis, and epithelial-mesenchymal transition (EMT) were evaluated by MTT, transwell invasion assays, flow cytometry analyses, and western blot examination of EMT markers. The binding activity between miR-128-3p and circ-ABCB10 or zinc finger E-box binding homeobox 1 (ZEB1) was explored through pull-down assay or luciferase reporter assay. The influence of circ-ABCB10 on CC tumorigenesis was evaluated by in vivo xenograft experiments. RESULTS: The elevated circ-ABCB10 expression was determined in CC tissues and cells. Moreover, higher production level of circ-ABCB10 was close related to lymph-node metastasis, Federation of Gynecology and Obstetrics (FIGO) stage, and tumor size in CC patients. Loss of circ-ABCB10 weakened cell proliferative and invasive abilities, inhibited EMT, and induced apoptosis in CC. Loss of circ-ABCB10 inhibited ZEB1 expression by serving as a sponge of miR-128-3p in CC cells. Circ-ABCB10 sponged miR-128-3p to enhance cell proliferation, invasion, EMT and inhibit apoptosis in CC cells. Xenograft tumor assays confirmed that circ-ABCB10 knockdown inhibited CC tumor growth. CONCLUSION: Our study suggests that circ-ABCB10 depletion inhibits proliferation, invasion and EMT and promotes apoptosis of cervical cancer cells through miR-128-3p/ZEB1 axis and represses CC tumor growth. |
