Figure 3. lncRNAs regulated the invasion ability of BLCA cell lines. Invasion assay was employed to monitor the effect of lncRNA expression on cell invasiveness. Specific small interfering RNAs (siRNAs) were used to knockdown the lncRNAs expression in human BLCA BIU-87 cells. Representative images of invasion assay were presented in (A), and the qualification result was shown in (B).
