... impair a cellular function exclusively performed by bilitranslocase. The uptake of BSP into HepG2 cells was in fact only partially inhibited by nicotinic acid, leaving intact the activity of ... supported by the observa- tion that the uptake of ICG, a high-affinity substrate of OATP1B1 [15], is not affected by taurocholate. However, the partial inhibition of both bilirubin and ICG up...

... The inhibition reversibility was studied by adding 1 m M EDTA, pH 8.0, to the reaction medium. The inhibition by Zn-ferrocyanide of d ifferent FNR variants was studied by assaying ferricyanide diaphorase activity ... no e ffect was observed by Zn 2+ addition on the DCPIP diaphorase activity (Fig. 1A). NADPH oxidation catalyzed by FNR in the presence of Fd or F ld was not affected b...
