description: Raw dataset 1: HeLa cells stably transfected with the plasmid F508del-CFTR were used in this experiment. a) The first lane represents F508del-CFTR HeLa cells non-treated. The second lane represents F508del-CFTR HeLa cells treated with TNFa at 50ng/ml for 10 min. The third lane represents F508del-CFTR HeLa cells treated with TNFa at 50ng/ml for 3h.The fourth lane represents F508del-CFTR HeLa cells treated with TNFa at 50ng/ml for 24h.

The anti-CFTR used is MM-13-4 (mouse antibody). b) The membrane has been stripped and the a-tubulin has been used. This is represented by the second western blot. Stripping procedure: after the first detection of CFTR proteins on the blot, the nitrocellulose membrane is incubated for 30 min in a stripping buffer containing 2% SDS, 625mM TRIS pH 6.7, then the membrane is washed 3 times with PBS during 10 minutes. Next, the membrane is blocked again as described in the protocol of western blot, followed by the use of new first antibody and detected as described in the protocol of western blot.

The normalized with regard to cell surface evaluated by measuring the cell capacity (C, pF) values of I<sub>CFTR</sub> current values obtained in control, non-treated conditions, used to calculates the mean values showed in Fig 3B (between -100mV and +80mV) the mean values for each imposed voltage are presented in the bottom of the corresponding column. The values at -60mV are in blue as they served for the statistics shown in Figure 3C Table “10 min 50 ng/ml TNFa I<sub>CFTR</sub>/C”. See legend for Table “BasaI I<sub>CFTR</sub>/C”. Here the cells were exposed to 50 ng/ml TNFa for 10 min. Raw dataset 4: The normalized current values measured in individual cells which were used to calculate the mean currents shown in Figure 3C. Each cell served as its own control. The currents were measured after 10 min of perfusion with cAMP cocktail (CPTAMPc and IBMX, see methods), then the TNFa was added to the perfusion in the presence of cAMP cocktail for next 10 min followed by perfusion of CFTR inh 172 (see methods and legends of fig 3C for details).

The mean values and the standard error of the mean for each imposed voltage are presented in the bottom of the corresponding column. The values at -60 mV are shown in blue as they served for the histogram shown in Figure 4 (right panel). Table “I <sub>CFTR</sub> /C (pA/pF) cAMP/IBMX control”.

A different set of cells served for control and IL1b treated cells. The values for TNFa treated cells are the same as shown in Fig 3C and in the raw data for Figure 3. Raw dataset 7: As for the legend for Figure 3B raw data except that the cells were pretreated with BFA (see methods and text for details).
