Inhibitory effect of clemastine on P-glycoprotein expression and function: an in vitro and in situ study
Objective(s):Transporters have an important role in pharmacokinetics of drugs. Inhibition or induction of drug transporters activity can affect drug absorption, safety, and efficacy. P-glycoprotein (P-gp) is the most important membrane transporter that is responsible for active efflux of drugs. It is important to understand which drugs are substrates, inhibitors, or inducers of P-gp to minimize...
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 کاملP-glycoprotein expression on normal and abnormally expanded natural killer cells and inhibition of P-glycoprotein function by cyclosporin A and its analogue, PSC833.
P-glycoprotein (P-gp), a transmembrane efflux pump encoded by the MDR1 gene, has been found to be expressed in many normal bone marrow and peripheral blood cells. Among normal leukocytes, CD3(-)CD16(+) or CD3(-)CD56(+) lymphocytes, ie, natural killer (NK) cells, express relatively high levels of P-gp, but little is known about P-gp in abnormally expanded NK cells. In this study, we examined the...
متن کاملNormal variation in mononuclear cell gene expression Variation in gene expression profiles of peripheral blood mononuclear cells from healthy volunteers
The normal degree of intraand inter-individual variation in gene transcription profiles of healthy human tissues has not been extensively investigated. In the study described here, microarrays were employed to analyse gene transcription in peripheral blood mononuclear cells prepared from serial blood samples that had been obtained, at weekly intervals, from apparently healthy human volunteers. ...
متن کاملBlood-brain barrier P-glycoprotein function in Alzheimer's disease.
A major pathological hallmark of Alzheimer's disease is accumulation of amyloid-β in senile plaques in the brain. Evidence is accumulating that decreased clearance of amyloid-β from the brain may lead to these elevated amyloid-β levels. One of the clearance pathways of amyloid-β is transport across the blood-brain barrier via efflux transporters. P-glycoprotein, an efflux pump highly expressed ...
