CYP2C11 and CYP2C23 epoxygenases were highly expressed in interlobar renal arteries and renal cortex, respectively, and were co-localized with eNOS in renal endothelial cells. These results demonstrate that H2O2 is involved in the EDH-type relaxant responses of renal arteries and that CYP 2C epoxygenases are physiologically relevant endothelial sources of vasodilator H2O2 in the kidney.
Title: CYP epoxygenase-derived H(2)O(2) is involved in the endothelium-derived hyperpolarization (EDH) and relaxation of intrarenal arteries.
Epoxygenase activity of cultured astrocytes and neurons shows reduction in total epoxyeicosatrienoic acids and DiHETE production (to 80% and approximately 70% of vehicle respectively) in presence of amyloid beta.
Title: Differential effect of amyloid β on the cytochrome P450 epoxygenase activity in rat brain.
docosahexaenoic acid-mediated vasodilatation is mediated through CYP epoxygenase metabolites by activation of vascular BK channels
Title: Activation of vascular BK channels by docosahexaenoic acid is dependent on cytochrome P450 epoxygenase activity.
High dietary potassium enhances the inhibitory effect of arachidonic acid and 11,12-epoxyeicosatrienoic acid on ENaC by increasing cytochrome P450 epoxygenase activity and decreasing soluble epoxide hydrolase activity, respectively.
Title: High potassium intake enhances the inhibitory effect of 11,12-EET on ENaC.
Increased vascular tone brought about by downregulation of CYP2C23 and decreased levels of vasodilatory EETs may constitute important factors in androgen-induced hypertension.

low sodium intake downregulates the activity and expression of CYP2C23 and attenuates the inhibitory effect of arachidonic acid on sodium transport
Title: Low Na intake suppresses expression of CYP2C23 and arachidonic acid-induced inhibition of ENaC.
These data suggest that TNF-alpha contributes to downregulation of Cyp2c23, blood pressure regulation, and renal injury in angiotensin high-salt hypertension.
Title: Tumor necrosis factor alpha blockade increases renal Cyp2c23 expression and slows the progression of renal damage in salt-sensitive hypertension.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
