LINC01314 was identified to target the KLK4 gene. a Heat map of differentially expressed lncRNAs associated with GC. The abscissa indicates the sample number, and the ordinate represents the differentially expressed gene. The top right histogram is the color gradation. Each rectangle corresponds to a sample expression value. Red indicates high expression and green indicates low expression. b Binding sites between LINC01314 and KLK4-3′UTR predicted using the biological prediction website. c Luciferase activity detected using dual-luciferase reporter gene assay. *p < 0.05, compared with the NC group.
