Fig 6 — (A) Three siRNA were designed and Wnt1 protein level was detected by western blot to select the effective siRNA for the target protein. siRNA#2 exhibited greatest inhibition of Wnt1 protein and was further validated in A549 cells. β-actin was used as a loading control. (B) Both A549 and H1299 cells transfected with siRNA-Wnt1 resulted in inhibition of cell migration using wound-healing assay. (C) Transfection of A549 and H1299 cells with siRNA-Wnt1 inhibited cell invasion using transwell migration assays. Images were captured at 200× optical magnification.
