Fig. 5From: Reduced expression of folate transporters in kidney of a rat model of folate oversupplementationEffect of structural analogs and inhibitors on the uptake of [14C]-5-methyltetrahydrofolate in the renal BBMV. Uptake of [14C]-5-methyltetrahydrofolate (0.5 μM) was measured with and without analog/inhibitor in incubation buffer of pH 5.5. Each data point is mean ± SD of four separate uptake determinations. *p < 0.05; **p < 0.01, ***p < 0.001 versus noneBack to article page
