Figure S3. Modulation of cav-1 expression in MRC-5 cells. Immunoblot analysis of cav-1 expressions in MRC-5 cells under different conditions. (A) Infection with different dosages of ad-cav-1 or ad-lacZ virus or no virus for 48 h. (B) Infection with 100 PFU/cell of ad-cav-1 or ad-lacZ virus or no virus for 1-4 d. (C) cav-1 stably transfected MRC-5 cells and vector stably transfected cells. (D) MRC-5 cells were transfected with siRNA targeting human cav-1 or control siRNA for 24 h.
