Figure 2. MiR-191 transfection efficiency and cell proliferation. (A, B) Expression level of miR-191 (in fold of NCm or percentage of NCi) in HUVECs that were transfected with miR-191 mimic (A) or miR-191 inhibitor (B) as assessed by real-time PCR (n=6 per group); (C, D) Proliferation (percentage of NCm or NCi) of HUVECs transfected with miR-191 mimic (C) or miR-191 inhibitor (D) as assessed by CCK-8 assay (n =6 per group). After transfection, the cells were reseeded into 96-well plates and incubated for another 48 h. Means ± SEM. ** P< 0.01 vs. NCm or NCi.
