Figure 3. — lncINS-IGF2 knockdown inhibits cell proliferation and colony formation in NSCLC cells. A549 and H1299 cells transfected with control siRNA or lncINS-IGF2 siRNA were trypsinized and plated into 96-well plates for the MTT assay. The asterisk shows the significant differences on the proliferation rate between 2 groups (A and B). Colony formation of A549 and H1299 cells at 14 days after transfection with the indicated oligonucleotides (C and D). *P < .05 versus NC. Data are expressed as the mean (SD) and each experiment was performed in triplicate. NSCLC indicates non-small-cell lung cancer; siRNA, small interfering RNA; MTT, 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide; NC, normal control; SD, standard deviation.
