Long non-coding RNA RP11-59H7.3 promotes cell proliferation and invasion metastasis in colorectal cancer by miR-139-5p/NOTCH1 axis

Figure 6. RP11-59H7.3 sponges miR-139-5p and moderate expression of NOTCH1. (A) The activity of luciferase of a luciferase reporter vector (pLuc) harboring mutant RP11-59H7.3 or wild-type co-transfected by miR-139-5p was evaluated using the dual luciferase assay. (B) cell lysates of SW480 cells were used for RIP with an IgG antibody or anti-Ago2 antibody. The miR-139-5p and RP11-59H7.3 levels were analyzed using RT-qPCR. (C) pLuc plasmid and miR-139-5p harboring NOTCH1 3'UTRs were co-transfected by pcDNA-RP11-59H7.3 or empty vector into cells of 293T to determine whether RP11-59H7.3 could act as a ceRNA of miR-139-5p. (D, G) The NOTCH1 expression levels in cells of SW480 prior transfected by pcDNA-RP11-59H7.3 and LoVo cells prior transfected by sh-lncRNA-RP11-59H7.3 were determined using western blot and RT-qPCR. (E, F) Analysis of correlation between expression of RP11-59H7.3/miR-139-5p and RP11-59H7.3/NOTCH1. **p < 0.01; *p < 0.05.
