We describe functional expression of the mouse multidrug-resistance protein (P-glycoprotein; P-gp) in an Escherichia coli mutant defective in the outer membrane protease ompT. Heterologously expressed mdr1 appears as an unglycosylated species with an apparent molecular mass of 140 kDa in

The effect of lipophilic cations such as triphenylmethylphosphonium, tetraphenylphosphonium and tetraphenylarsonium in addition to dibenzyldimethylammonium on thiamine transport in isolated rat hepatocytes was studied. Lipophilic cations at the concentration 10 microM almost completely inhibited thiamine uptake. Kinetic studies showed that

In this preliminary study, we report the cloning of the human MDR1 cDNA into a prokaryotic expression vector and the consequent functional expression of heterologous P-glycoprotein in Escherichia coli. We demonstrate increased resistance to the P-glycoprotein substrates TPA+, TPP+, and

The effect of the hetaerons tetraphenylarsonium chloride (Ph4AsCl) and tetraphenylarsonium perchlorate (Ph4AsClO4) on the retention of neutral and cationic metalloporphyrins on a reversed-phase column with an acetonitrile-tetrahydrofuran (85:15, v/v) mobile phase was investigated. The adsorption properties of the two hetaerons
