siRNA-mediated depletion (KD) of A) BRD8, EHF, KLF5 and B) ING2, NR2F2, enhances CFTR mRNA abundance. RT-qPCR measurements of CFTR normalized to the geometric mean of three house-keeping gene controls, β2 microglobulin (β2M), phosphoglycerate kinase (PGK) and β actin (ACTB) and shown relative to negative control (NC). Bar shows average of 3 experiments with standard error of the mean. Key: *** P<0.001, **** P<0.0001 by an unpaired two-tailed Student’s t test.
