Time dependence of [3H]-vincristine accumulation by L1210 mouse leukemic cells. Effect of P-glycoprotein overexpression.
Overexpression of P-glycoprotein (P-GP) accompanied by multidrug resistance (MDR) to diverse groups of cytostatics was developed by long-term adaptation of mouse leukemic cell line L1210 to vincristine. Two resistant sublines of cells characterized by ID50 values for vincristine 1.05 mg/l (L1210/VCR-1) and 2.3 mg/l (L1210/VCR-2), respectively, were used. The sensitive parental cell line L1210 h...
متن کاملEffect of Honey on CYP3A4 Enzyme and P-Glycoprotein Activity in Healthy Human Volunteers
The activity of cytochrome p450 isozyme 3A4 (CYP3A4) enzyme and P-glycoprotein (P-gp) is modulated by grapefruit juice and herbal drugs. CYP3A4 is the major phase I drug metabolizing enzyme and P-gp is an ATP-dependent drug efflux pump that regulates the intestinal absorption of orally administered drugs. Honey is commonly consumed as a dietary supplement. However, its influence on human CY...
متن کاملRefined structures of mouse P-glycoprotein
The recently determined C. elegans P-glycoprotein (Pgp) structure revealed significant deviations compared to the original mouse Pgp structure, which suggested possible misinterpretations in the latter model. To address this concern, we generated an experimental electron density map from single-wavelength anomalous dispersion phasing of an original mouse Pgp dataset to 3.8 Å resolution. The map...
متن کاملP 149: Effect of Glycoprotein IIb/IIIa Inhibition on Acute Ischemic Stroke Injuries
Ischemic stroke accounts for about 87 percent of all cases. It occurs as a result of an obstruction within a vessel of the brain and sudden loss of blood circulation to the corresponding area resulting in the loss of brain function. It is caused by thrombotic or embolic occlusion of an artery and is more common than hemorrhagic stroke. We know that most of the injuries after an acute ischemic s...
متن کاملTunicamycin Depresses P-Glycoprotein Glycosylation Without an Effect on Its Membrane Localization and Drug Efflux Activity in L1210 Cells
P-glycoprotein (P-gp), also known as ABCB1, is a member of the ABC transporter family of proteins. P-gp is an ATP-dependent drug efflux pump that is localized to the plasma membrane of mammalian cells and confers multidrug resistance in neoplastic cells. P-gp is a 140-kDa polypeptide that is glycosylated to a final molecular weight of 170 kDa. Our experimental model used two variants of L1210 c...
