In contrast, there was a marked trend for a greater FU efficacy in mutated A1298C variants (C/C+A/C) as compared to wt homozygous cell lines (A/A) ( P =0.055 and 0.085 without and with FA supplementation, respectively).
In contrast, there was a marked trend for a greater FU efficacy in mutated A1298C variants (C/C+A/C) as compared to wt homozygous cell lines (A/A) ( P =0.055 and 0.085 without and with FA supplementation, respectively).
In ‘physiological-folate’ conditions, FU IC 50 ranged from 0.6 to 25.4 μ M (median 8.4) in the 10 cell lines exhibiting wt A/A 1298 variant, whereas IC 50 were comprised between 0.3 and 7.3 (median 2.9) in the nine cell lines exhibiting mutated A/C or C/C 1298 variants; this difference was very close to statistical significance (Mann–Whitney, P =0.055).
The above observations, which did not reach statistical significance, are depicted in Figure 5 .
