In addition, the effects of AF were examined on cytochrome P450 (CYP) 2E1, the major isozyme involved in APAP bioactivation. | |||||||||||||||
| |||||||||||||||
|
The expression of interferon-gamma (IFN-gamma) in serum and alpha-and mu-class of gluthathione-S-transferase (GSTs), CYP 2E1 class of cytochrome monooxygenase and glutathione (GSH) in liver were quantified. | |||||||||||||||
| |||||||||||||||
|
To this end, hepatic activities of aminolevulinic acid synthase (ALAS), heme oxygenase (HO) and CYP levels were determined in mice treated with CP-55,940 (0.5 mg/kg/day; i.p.; 5 or 24 days). | |||||||||||||||
| |||||||||||||||
|
Expression of cytochrome P450 (CYP) isozymes was determined using antibodies of 2E1 and 1A2 as probes. | |||||||||||||||
| |||||||||||||||
|
Metabolism by CYP and GSH conjugation are common metabolic pathways for many drugs such as APAP. | |||||||||||||||
| |||||||||||||||
|
GR and LXR were significantly up-regulated in BAL cells, but no clear correlation between CYP mono-oxygenases and nuclear receptor gene expression was observed. | |||||||||||||||
| |||||||||||||||
|
Likewise, changes in the expression of CYP transcripts may influence an individuals capacity to convert different precarcinogenic compounds into their ultimate carcinogens; therefore, these CYP transcripts are of major importance for an individuals susceptibility of developing chemically induced cancer. | |||||||||||||||
| |||||||||||||||
|
Serum CXCL9, CXCL10, and CXCL11 levels of CYP-treated mice given control Ab were compared to similar mice that received anti-CXCL10 Ab. | |||||||||||||||
| |||||||||||||||
|
This shift in the expression of the CYP epoxygenase gene might alter production of epoxy fatty acids, some of which are considered to be signalling molecules affecting vascular- and smooth muscle cell tone. | |||||||||||||||
| |||||||||||||||
|
Urinary bladder histology as well as mucosal (iliac lymph node and urinary bladder) and peripheral (spleen) leukocyte expression of CXCR3, CXCL9, CXCL10, and CXCL11 mRNA transcripts as well as CD4+ T cell, mast cell, and NK/NKT cell numbers were compared among naïve and CYP-treated mice given control or anti-CXCL10 Abs. | |||||||||||||||
| |||||||||||||||
|
In general, the distribution of CD3+CD8+, DX-5+, and CD11b+ lymphocytes changed little after CYP-induced cystitis. | |||||||||||||||
| |||||||||||||||
|
Due to the high levels of CXCL10 observed during CYP-induced cystitis, we next treated mice with control or anti-CXCL10 Abs to determine if inhibition of this chemokine would modulate disease. | |||||||||||||||
| |||||||||||||||
|
These clinical trends were consistent with CYP-induced cystitis in mice; CXCR3 ligands were elevated in mouse serum as well as urinary bladder and iliac lymph node lymphocytes. | |||||||||||||||
| |||||||||||||||
|
In the present study, we noticed significant increases in mast cell numbers in the spleen, iliac lymph nodes, and urinary bladder after CYP induction and these increases were abrogated by anti-CXCL10 Ab treatment. | |||||||||||||||
| |||||||||||||||
|
The mechanism by which malaria down-modulates the expression and activity of other CYP isoforms is still unclear. | |||||||||||||||
| |||||||||||||||
|
The idea that NO is a mediator of the down-modulation of CYP expression by inflammatory stimuli is plausible because NO binds haem proteins and inhibits catalytic activities of CYPs in in vitro test systems [16,17]. | |||||||||||||||
| |||||||||||||||
|
Thus, information about the expression of CYP families and subfamilies should be valuable from two viewpoints. | |||||||||||||||
| |||||||||||||||
|
Of note, CYP3A4 is the most abundantly expressed CYP in h-liver and metabolizes >60% of all therapeutic drugs; collectively, CYP2D6 and CYP3A4 metabolize >70% of the drugs on the market [17]. | |||||||||||||||
| |||||||||||||||
|
Second, the h-CYP-expressing chimeric mouse is a useful experimental model for studying h-type metabolic responses to xenobiotics, including clinically valuable drugs. | |||||||||||||||
| |||||||||||||||
|
Thus, the h-hepatocytes in the chimeric mice appeared to express the six h-CYP genes in a manner similar to their expression in the h-body. | |||||||||||||||
