Figure 3. Overexpression of miR-124 increases cell apoptosis in vitro.

(A) SW480 and LoVo cells were transfected with Pre-miR-124 or Pre-Scrambled miRNA and examined by light microscope. (B) Cells were transfected with Pre-miR-124 or Pre-Scrambled miRNA, and cell growth was determined by WST1 assay. Columns represent mean of three independent tests. Bars, SD. *, P<0.05. (C) Cell apoptosis was measured by Annexin V and propidium iodine staining.
