This review addresses the function of the protein-transporter glycoprotein-P (Pgp, ABCB1 protein) and the expression of its encoding gene MDR1/mdr1 throughout the gestational period in humans and animals. We discuss the relationship between the transporter function and the hormone fluctuations durin...

Mitoxantrone is a marker substrate of breast cancer resistance protein (BCRP). BCRP is involved in a number of pharmacokinetic drug-drug interactions. The transporter’s possible saturability makes it advisable to use low concentrations of mitoxantrone for in vitro studies. Consequently, mitoxantrone...

One way to analyze the activity of the ABCB1 protein is to assess the accumulation of its substrate fexofenadine (F.) inside the test cells. The goal is to develop and validate a method for the quantitative analysis of F. in Caco-2 cell lysate using HPLC-MS/MS. Materials and methods. Caco-2 cell lys...
