Abstract:
Objective To explore the effects of long non-coding RNA(lncRNA)small nucleolar molecule RNA host gene 12(SNHG12)targeting inhibition of miR-495-3p/phospholipinositol-3-kinase(PI3K)/protein kinase B(Akt)signaling pathway on the proliferation,migration and invasion of prostate cancer cells.Methods The expressions of SNHG12 and miR-495-3p in prostate cancer tissues and cells(LNCaP,C4-2,DU145)were detected with real-time fluorescence quantitative PCR(qRT-PCR).After DU145 cells were divided into si-NC,si-SNHG12,si-SNHG12+anti-miR-NC and si-SNHG12+anti-miR-495-3p groups,the expressions of SNHG12 and miR-495-3p were detected with qRT-PCR;the targeting relationship between SNHG12 and miR-495-3p was determined with dual luciferase assay;cell proliferation was assessed with MTT assay;cell migration and invasion were evaluated with Transwell assay;the protein expressions of proliferating cell nuclear antigen(PCNA),N-cadherin,and E-cadherin were detected with Western blot.Results The expressions of SNHG12 were significantly increased,while the expression of miR-495-3P was significantly decreased in prostate cancer tissues and cells(LNCaP,C4-2,DU145)(P＜0.05).Knockdown of SNHG12 decreased DU145 cell activity,lowered the protein expressions of PCNA and N-cadherin,reduced the number of migrating and invading cells,but increased the protein expression of E-cadherin(P＜0.05).SNHG12 targeted and negatively regulated miR-495-3p,and down-regulation of miR-495-3p reversed the effects of SNHG12 knockdown on the proliferation,migration and invasion of prostate cancer cells.Compared with the si-NC group,the si-SNHG12 group had significantly decreased expressions of p-PI3K and p-Akt(P＜0.05).Compared with the si-SNHG12+anti-miR-NC group,the si-SNHG12+anti-miR-495-3p group had significantly increased protein expressions of p-PI3K and p-Akt(P＜0.05).Conclusion lncRNA SNHG12 can promote the proliferation,migration and invasion of prostate cancer cells through targeted inhibition of miR-495-3p/PI3K/Akt signaling pathway.
