Figure 3. BMP9 rs7923671 and rs3740297 affect luciferase activities in PASMC cells. (A) relative luciferase activities of rs7923671 were measured in PASMC cells. (B) SNP-miRNA duplex for rs3740297 and miR-149. (C) relative luciferase activities of rs3740297 were measured in PASMC cells transfected with C allele, or T allele. Cells in different groups were treated with blank control, miR-149 mimic or antagomir-miR-149. Three replicates for each group and the experiment were repeated three times.
