Long non-coding RNA RP11-59H7.3 promotes cell proliferation and invasion metastasis in colorectal cancer by miR-139-5p/NOTCH1 axis
Figure 5. miR-139-5p is directly targeted by RP11-59H7.3. (A) miR-139-5p-binding sequence in NOTCH1 3'UTR and RP11-59H7.3. The mutation was induced in RP11-59H7.3 in the site complementary to the miR-139-5p binding. (B) RT-qPCR was performed to determine levels of miRNA in cells of SW480 post-transfection by pcDNA-RP11-59H7.3. The activity of luciferase in cells of 293T co-transfected by miR-139-5p (C) or miR-203 (D) mimics and the luciferase reporters (mutant RP11-59H7.3) or control (wild type RP11-59H7.3). The activity of renilla luciferase was determined then normalized to firefly luciferase activity level. Each experiment was repeated thrice, and the data are summarized as mean ± SD (two-tailed Student’s t-test). **p < 0.01; *p < 0.05.
