The present study further characterizes the expression of multidrug resistance-associated proteins 1-4 (Mrp1-4), breast cancer resistance protein (Bcrp) and sodium-taurocholate co-transporting polypeptide (Ntcp) in mouse liver following administration of the hepatotoxicants acetaminophen (APAP) and carbon tetrachloride (CCl4).

This resistance is mediated by many mechanisms including over-expression of proteins involved in inhibition of apoptosis (i.e, Bcl-2), leading to insensitivity of tumor cells to apoptotic stimuli; an up-regulation of DNA repair; alteration of the target; up-regulation of detoxification enzymes (i.e., Glutathione S-transferases); and extrusion of chemotherapeutic drugs by overexpression of ATP-binding cassette family proteins, such as MRP (multidrug resistant-associated protein) BCRP (breast cancer resistance protein or mitoxantrone resistance protein) because these proteins regulate absorption, distribution, and excretion of various pharmacologic compounds [141].

The cellular influx of dasatinib, on the other hand, is not affected by hOCT1 activity, although its efflux may be mediated by ABCB1 and ABCG2.85,86 The intracellular concentration of dasatinib was lower in ABCB1-overexpressing cell lines and was increased in the presence of PSC833, a potent ABCB1 inhibitor.85 The in vitro concentration of dasatinib required to inhibit phosphorylation of CrkL by 50% (dasatinib IC50) was higher in the ABCB1-overexpressing cell lines compared to parental cell lines (100 nM versus 7 nM), and this was reduced to 8 nM with the addition of PSC833.85 Similar results were also seen in the ABCG2-overexpressing cell lines, suggesting that high levels of ABCG2 reduced dasatinib intracellular concentration, leading to an increased dasatinib IC50, which can be modulated with ABCG2 inhibitors.85
