Elevated cytochrome P450 monooxygenase-based metabolism is associated with carbaryl and methyl parathion resistance in western corn rootworm (Diabrotica virgifera virgifera LeConte) populations in the state of Nebraska. The objectives of this study were to identify potential differences in cytochrome P450 in resistant and susceptible rootworm populations using the model substrate 4-chloro-N-met...

0892-h61R/q2/fl00E.fl7l 1/401 cft ( FAcIR ABSTRACT Arachidonic acid and many products of the arachidonate cascade serve as substrates for cytochrome P450-mediated metabolism via allylic oxidation, omega hydroxylation, and epoxygenation as well as peroxide rearrangement. Defining the physiological importance of these metabolites is an area of intense research interest. Cytochrome P450-catalyzed ...

Cytochrome P450 monooxygenases are involved in many cases of resistance of insects to insecticides. Resistance has long been associated with an increase in monooxygenase activities and with an increase in cytochrome P450 content. However, this increase does not always account for all of the resistance. In Drosophila melanogaster, we have shown that the overproduction of cytochrome P450 can be l...

INTRODUCTION There are limited treatment options for people with schizophrenia with cytochrome P450 2D6 ultrarapid metabolizer status who do not respond to amisulpride.Furthermore, the literature does not provide evidence-based guidelines for this particular constellation. CASE PRESENTATION We report the case of a 50-year-old Caucasian female patient with schizophrenia and cytochrome P450 2D6...

Cytochrome P450 metabolizes arachidonic acid to several unique and biologically active compounds in rabbit liver and kidney. Microsomal fractions prepared from rabbit lung homogenates metabolized arachidonic acid through cytochrome P450 pathways, yielding cis-epoxyeicosatrienoic acids (EETs) and their hydration products, vic-dihydroxyeicosatrienoic acids, mid-chain cis-trans conjugated dienols,...
