SNHG7 targeted miR-342-3p directly. a Schematic representation of binding sites between SNHG7 and miR-342-3p predicted by StarBase software. b Luciferase reporter assay was performed after co-transfection with reporter plasmid and miRNAs into HEK293T cells. c After transfection with siRNA of SNHG7 or negative control (NC), the expression level of miR-342-3p was measured by RT-qPCR. d After transfection with miR-342-3p mimics or miRNA negative control (miR-NC), SNHG7 expression level was measured by RT-qPCR. e The expression levels of miR-342-3p in PC tissues and adjacent normal ones were determined by RT-qPCR. f Negative correlation between SNHG7 and miR-342-3p in PC tissues. **P < 0.01, compared with miR-NC group, si-NC group or normal tissue group
