Effects of P-Glycoprotein and Its Inhibitors on Apoptosis in K562 Cells

open access: yesMolecules, 2014
P-glycoprotein (P-gp) is a major factor in multidrug resistance (MDR) which is a serious obstacle in chemotherapy. P-gp has also been implicated in causing apoptosis of tumor cells, which was shown to be another important mechanism of MDR recently.

Predicting P-glycoprotein-mediated drug transport based on support vector machine and three-dimensional crystal structure of P-glycoprotein. [PDF]

open access: yesPLoS ONE, 2011
Human P-glycoprotein (P-gp) is an ATP-binding cassette multidrug transporter that confers resistance to a wide range of chemotherapeutic agents in cancer cells by active efflux of the drugs from cells.

Selective modulation of P-glycoprotein activity by steroidal saponines from Paris polyphylla [PDF]

open access: yes, 2009
Bio-guided fractionation of the roots of Paris polyphylla (Trilliaceae), based on inhibition of P-glycoprotein-mediated daunorubicin efflux in K562/R7 cell line, led to isolation and identification of the three saponins 3-O-Rha(1 → 2)[Ara(1 → 4)]Glc ...

P-glycoprotein Inhibition for Optimal Drug Delivery

open access: yesDrug Target Insights, 2013
P-glycoprotein (P-gp), an efflux membrane transporter, is widely distributed throughout the body and is responsible for limiting cellular uptake and the distribution of xenobiotics and toxic substances. Hundreds of structurally diverse therapeutic agents

Not only P-glycoprotein: amplification of the ABCB1-containing chromosome region 7q21 confers multidrug resistance upon cancer cells by coordinated overexpression of an assortment of resistance-related proteins [PDF]

open access: yes, 2017
The development of drug resistance continues to be a dominant hindrance toward curative cancer treatment. Overexpression of a wide-spectrum of ATP-dependent efflux pumps, and in particular of ABCB1 (P-glycoprotein or MDR1) is a well-known resistance ...

P-Glycoprotein in Clinical Cardiology [PDF]

open access: yesCirculation, 1999
Ever since Juliano and Ling first described P-glycoprotein (P-gp) in 1975,1 it has become an important focus of research. P-gp is a member of the ATP-binding cassette (ABC) superfamily of proteins that is highly conserved in distantly related species (from simple eukaryotes to vertebrates).2 These similarities across species suggest that P-gp plays an ...

Allelic variations of the multidrug resistance gene determine susceptibility and disease behavior in ulcerative colitis [PDF]

open access: yes, 2005
BACKGROUND AND AIMS: The MDR1 gene encodes P-glycoprotein 170, an efflux transporter that is highly expressed in intestinal epithelial cells. The MDR1 exonic single nucleotide polymorphisms (SNPs) C3435T and G2677T have been shown to correlate with ...
