Conceivable that–at one particular or more of these metabolic steps– CYP1 enzymes

Conceivable that–at one particular or far more of these metabolic steps– CYP1 enzymes may possibly clear metabolites associated to the zymosan challenge, rather than metabolizing LMs straight; failure to clear those metabolites within the absence of CYP1 might cause an alteration in neighborhood cellular response which, in turn, might produce a change in LM mediator production by cyclooxygenases and ALOXs.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptJ Immunol. Author manuscript; readily available in PMC 2014 September 15.Divanovic et al.PageTherefore, future experiments–in zymosan-challenged mice genetically lacking only certainly one of the Cyp1a1, Cyp1a2 or Cyp1b1 genes–will be essential to further dissect which particular CYP1 monooxygenase participates in each specific metabolic step. Because of the higher degree of conserved functions and substrate specificities identified to exist in between the three mouse and 3 human CYP1 enzymes, such a reductionist approach need to bring about elucidation of clinically essential novel drug targets.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptSupplementary MaterialRefer to Internet version on PubMed Central for supplementary material.AcknowledgmentsWe thank our colleagues, especially Larry Marnett (Vanderbilt) for useful discussions and/or cautious reading with the manuscript. We are indebted to Dr. Frank J Gonzalez for sharing his Cyp1b1( knockout line far more than a decade ago, which has helped immensely in our combined-knockout mouse breeding research.
