Figure 4From: Activation of chloride transport in CF airway epithelial cell lines and primary CF nasal epithelial cells by S-nitrosoglutathioneThe effect of GSNO on intracellular ion composition in CFSME cells assessed by X-ray microanalysis method. "Control": Cells kept 2 min in Cl--free SR. "GSNO": cells treated with 60 μM GSNO for 4 hours, then exposed for 3 min to Cl--free SR. fors+IBMX = 3 min exposure to Cl--free SR containing 20 μM forskolin and 100 μM IBMX. Data are expressed as mean ± SEM. Significant difference from the control (ANOVA) is indicated by asterisks (* p < 0.05, ** p < 0.01).Back to article page
