The Effects of Drugs on CYP3A Enzyme Activity and Protein Expression Through Ubiquitination Modification Regulation. [PDF]
ABSTRACT Cytochrome P450 3A4 (CYP3A4) is one of the most important members of the cytochrome P450 subfamily, which is involved in the catalytic process of many drug activation or deactivation. Meanwhile, it is also a risk factor for drug‐induced toxic reactions.

Population Pharmacokinetic and Exposure-Response Analyses of Ibrutinib Combined With Bendamustine and Rituximab in Patients With Mantle Cell Lymphoma. [PDF]
ABSTRACT Efficacy and safety of ibrutinib 560 mg once daily or placebo combined with bendamustine and rituximab (BR) were assessed in patients with mantle cell lymphoma in a randomized phase 3 study (SHINE). The analysis described explores the ibrutinib population pharmacokinetics (PK) and exposure‐response (E‐R) relationships of selected efficacy and ...

Association of Metabolic Genotype Composite CYP3A5*3 and CYP3A4*1B to Tacrolimus Pharmacokinetics in Stable Black and White Kidney Transplant Recipients. [PDF]
ABSTRACT Interpatient variability in tacrolimus pharmacokinetics is due in part to variation in metabolism by cytochrome P‐450 3A5 and 3A4 and membrane transport by P‐glycoprotein. We evaluated the combined role CYP3A5*3 and CYP3A4*1B genotypes have on tacrolimus pharmacokinetics in 65 stable Black and White kidney transplant recipients receiving ...

Inhibitory Effect of Antituberculosis Drugs on Human Cytochrome P450-Mediated Activities
The potential for drug-drug interactions mediated by the inhibition of cytochrome P-450 (CYP) were concerned during antituberculosis therapy. However, the information regarding human CYP inhibition by antituberculosis drugs is limited to isoniazid.

Metabolic differences in colon mucosal cells [PDF]
The colonic expression of cytochromes P450 from the CYP1A, CYP3A and CYP4B subfamilies has been characterized in rabbit and human tissues using RNA blotting, immunoblotting, immunohistochemistry and hybridization histochemistry. These studies demonstrate
