Silencing circular RNA-ZNF652 represses proliferation and EMT process of renal carcinoma cells via raising miR-205.

Recently, the functions of circular RNAs (circRNAs) on cancer initiation and development arouse wide concern. Herein, we tested the influences of circ-ZNF652 on renal carcinoma cell growth and metastasis. Firstly, clinical renal carcinoma tissues and corresponding normal tissues were collected. The circ-ZNF652 expressions were tested. Then, the influences of silencing circ-ZNF652 on renal carcinoma A498 and ACHN cell proliferation, apoptosis and epithelial-mesenchymal transition (EMT) process, as well as Ras/Raf/MEK/ERK and JAK1/STAT3 pathways, were probed. Finally, whether miR-205 engaged in the influences of silencing circ-ZNF652 on A498 and ACHN cell were investigated. circ-ZNF652 had high expression level in clinical renal carcinoma tissues. Silencing circ-ZNF652 repressed A498 and ACHN cell proliferation and EMT process, but promoted cell apoptosis. Moreover, silencing circ-ZNF652 suppressed Ras/Raf/MEK/ERK and JAK1/STAT3 pathways in A498 and ACHN cells. Besides, the miR-205 expressions in A498 and ACHN cells were raised by silencing circ-ZNF652. Knockdown of miR-205 weakened the influences of silencing circ-ZNF652 on A498 and ACHN cell proliferation, apoptosis and EMT process. Silencing circ-ZNF652 repressed proliferation and EMT process of renal carcinoma A498 and ACHN cells suppressing Ras/Raf/MEK/ERK and JAK1/STAT3 pathways, as well as raising miR-205 expression.
