Figure 3. Correction of class II CFTR variants by siRNA knockdown of target proteins.
A. Immunoblot analysis of CFTR and tubulin from a lysate prepared from CFBE41o- null cells transfected with the indicated siRNA and transduced with the indicated CFTR variant. B–E. Bar graph of the amount of band C detected by quantitation of the immunoblot shown in panel A for F508del-CFTR (B), G85E-CFTR (C), R560T-CFTR (D) and N1303K-CFTR (E). The data shown in panels B–E represents the percentage of band C relative to band B in the control siRNA condition (siScr). The data for the siScr represents n = 2 and the data for the siRNA knockdown for the CFTR variants are a single replicate (n = 1).
