The differences, in fact, between [14C]DHA release in NT and GM-CSF conditions were statistically different in the CT group, but not in the CF group (P < 0.002 and P = 0.09 in CT and CF, respectively) and consequently, release was significantly higher in CT as compared to CF cells after GM-CSF stimulation (Table 2). This evidence concerns the gene CSF2 and cystic fibrosis.
