Effect of shRNA-mediated knockdown of the hit genes on surface expression of ΔF508-CFTR. 293MSR-GT cells stably expressing ΔF508-CFTR (bearing a 3HA tag at the ectodomain) were transfected with shRNA for the analyzed genes or nonsilencing control (as indicated), grown at 37 °C for 48 h, selected on puromycin, and quantitation of surface expression of ΔF508-CFTR was carried out by ELISA assay. SU5402 represents cells treated with SU5402 and serves as a positive control. Data are mean ± S.E. from three independent experiments.
