Biological function: Results Compared with the pLO-ciR(empty plasmid)group,the Oe-circ_0067582 group in AGS and SGC-7901 cells attenuated the cell viability(t=7.883,P=0.001;t=5.679,P=0.005),proliferation(t=6.709,P=0.003;t=5.857,P=0.003),and invasion ability(t=7.782,P=0.002;t=6.342,P=0.003)and induced cell apoptosis(t=7.225,P=0.002;t=11.509,P=0.001).Western blotting showed that the Oe-circ_0067582 group in AGS and SGC-7901 cells up-regulated the protein levels of cysteinyl aspartate specific proteinase (Caspase) 3(t=6.863,P=0.002;t=7.024,P=0.001),Caspase 7(t=3.295,P=0.04;t=6.008,P=0.004),Caspase 9(t=4.408,P=0.012;t=6.278,P=0.004),and E-cadherin(t=12.453,P=0.002;t=10.867,P=0.001),while down-regulated those of Vimentin(t=7.242,P=0.002;t=5.694,P=0.004)and N-cadherin(t=6.480,P=0.003;t=7.446,P=0.001).Furthermore,Oe-circ_0067582 significantly inhibited the growth of tumor in the SGC-7901 tumor-bearing nude mice(t=3.526,P=0.017).The prediction based on TargetScan and miRnada suggested that hsa_circ_0067582 can competitively bind to hsa-miR-181b-3p,hsa-miR-337-3p,hsa-miR-421,and hsa-miR-548d-3p.
Molecular mechanism: The functional enrichment indicated that the target genes of miRNA were involved in multiple cancer-related biological processes including negative regulation of apoptotic process,gene expression,transcriptional misregulation in cancer,transforming growth factor-beta,and p53 signaling pathways.

Description:

Oe-circ_0067582 can inhibit the proliferation and attenuate EMT process to reduce the invasion ability of AGS and SGC-7901 cells,which provides a new target for the treatment of GC.
