Rat precision-cut intestinal slices to study P-gp activity and the potency of its inhibitors ex vivo.
Rat Precision-Cut Intestinal Slices (PCIS) were evaluated as ex vivo model to study the regional gradient of P-gp activity, and to investigate whether the rank order of inhibitory potency of P-gp inhibitors can be correctly reproduced in this model with more accurate IC50 values than with current in vitro models. PCIS were prepared from small intestine (duodenum, jejunum, ileum) and colon. Rhod...
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 کاملPrecision-cut rat, mouse, and human intestinal slices as novel models for the early-onset of intestinal fibrosis
Intestinal fibrosis (IF) is a major complication of inflammatory bowel disease. IF research is limited by the lack of relevant in vitro and in vivo models. We evaluated precision-cut intestinal slices (PCIS) prepared from human, rat, and mouse intestine as ex vivo models mimicking the early-onset of (human) IF. Precision-cut intestinal slices prepared from human (h), rat (r), and mouse (m) jeju...
متن کاملBiaxial distension of precision-cut lung slices.
The mechanical forces acting on lung parenchyma during (mechanical) ventilation and its (patho)physiological consequences are currently under intense scrutiny. Several in vivo and cell culture models have been developed to study the pulmonary responses to mechanical stretch. While providing extremely useful information, these models do also suffer from limitations in being either too complex fo...
متن کاملThe Consequence of Drug-Drug Interactions Influencing the Interplay between P-Glycoprotein and Cytochrome P450 3a: An Ex Vivo Study with Rat Precision-Cut Intestinal Slices.
P-glycoprotein (P-gp) and cytochrome P450 3A (CYP3A) are differentially expressed along the intestine and work coordinately to reduce the intracellular concentration of xenobiotics and the absorption of orally taken drugs. Drug-drug interactions (DDIs) based on P-gp/CYP3A interplay are of clinical importance and require preclinical investigation. We investigated the P-gp/Cyp3a interplay and rel...
