Knockdown of SNHG1 inhibits cervical cancer growth through sponging miR-194 to regulate HCCR.

To investigate the mechanism of small nucleolar RNA host gene 1 (SNHG1) in cervical cancer (CC). The expression of SNHG1, miR-194 and human cervical cancer oncogene (HCCR) in CC tissues and cells was detected using qRT-PCR and western blot. The interaction among the three molecules was measured using dual-luciferase reporter assay and RNA immunoprecipitation assay. The function of SNHG1 in CC cells was detected by CKK-8 assay and flow cytometry analysis. SNHG1 was highly expressed in CC tissues and CC cell lines. Knockdown of SNHG1 inhibited CC cell proliferation and enhanced the ability of cell apoptosis. Mechanism investigation revealed that SNHG1 modulated HCCR expression acting as a competing endogenous RNA of miR-194. Moreover, miR-194 inhibitor changed the effects of si-SNHG1 on CC cells growth. experiment, silencing of SNHG1 suppressed CC tumor growth by modulating miR-194/HCCR axis. Knockdown of SNHG1 inhibited CC progression by targeting HCCR sponging with miR-194.
