LINC00242 knockdown suppressed cell viability and enhanced cell apoptosis in both MGC-803 and AGS, while inhibition of miR-1-3p revealed opposite impacts to LINC00242 on gastric cancer cell phenotype; inhibition of miR-1-3p markedly weakened the functions of LINC00242 silencing (Fig. 7c, d). Here, JAG1 is linked to gastric cancer.
