Previously, we reported that Candidatus Liberibacter asiaticus (Las)-infected Diaphorina citri are characterized by lower levels of cytochrome P450 monooxygenases than uninfected counterparts. In the present study, we investigated expression levels of family 4 cytochrome P450 (CYP4) genes in Las-infected and uninfected D.citri adults. Five novel CYP4 genes (CYP4C67, CYP4DA1, CYP4C68, CYP4DB1 an...

Genes coding for cytochrome P450 are regulated by endogenous hormones such as the growth hormone, corticosteroids, thyroid, and sex hormones. Secretion of these hormones is regulated by the respective hypothalamus–pituitary–secretory organ axes. Since the brain sends its serotonergic projections from the raphe nuclei to the hypothalamus, we have assumed that damage to these nuclei may affect th...

Objective: Though the adverse effects of pesticides used in agriculture may not immediately be visible in the human population however its long term exposure may cause detrimental effects by biomagnifications and bioaccumulation. Nowadays bioinformatics serves as an in silico tool not only for homology alignment but also for prediction of quaternary structures of biochemicals. The present study...

Angiotensin II and the arachidonic acid metabolite derived via cytochrome P450 20-hydroxyeicostetraenoic acid promote vasoconstriction and vascular smooth muscle cell (VSMC) proliferation. This study was conducted to determine if 20-hydroxyeicostetraenoic acid contributes to angiotensin II-induced neointimal formation in balloon-injured rat carotid artery. In anesthetized rats, the drugs were i...

Highly miniaturized P450 screening assays designed to enable facile analysis of P450 drug interactions in a 1536-well plate format with the principal human cytochrome P450 enzymes (CYP3A4, 2D6, 2C9, 2C19, and 1A2) and Vivid fluorogenic substrates were developed. The detailed characterization of the assays included stability, homogeneity, and reproducibility of the recombinant P450 enzymes and t...

Correction In our article (Sirim et al. BMC Struct Biol 2010, 10: 34) [1] the cytochrome P450 monooxygenase P450cam was referred to as CYP101D. In the latest release 3.0 of our cytochrome P450 database CYPED (www.CYPED.uni-stuttgart.de) P450cam was reassigned to family CYP101A and referred to as CYP101A1.
