Selective Modulation of Hepatic Cytochrome P450 and Flavin Monooxygenase 3 Expression during Citrobacter rodentium Infection in Severe Combined Immune Deficient (SCID) Mice

Selective modulation of hepatic cytochrome P450 and flavin monooxygenase 3 expression during citrobacter rodentium infection in severe combined immune-deficient mice.

The profile of selective modulation of hepatic cytochrome P450 (P450) gene expression caused by infection with the murine intestinal pathogen Citrobacter rodentium has been well characterized in multiple genetic backgrounds; yet, the mechanisms underlying this modulation are still not entirely understood. Although several studies have addressed the roles of cytokines from the innate immune syst...

Regulation of hepatic cytochrome P450 expression in mice with intestinal or systemic infections of citrobacter rodentium.

We reported previously that infection of C3H/HeOuJ (HeOu) mice with the murine intestinal pathogen Citrobacter rodentium caused a selective modulation of hepatic cytochrome P450 (P450) gene expression in the liver that was independent of the Toll-like receptor 4. However, HeOu mice are much more sensitive to the pathogenic effects of C. rodentium infection, and the P450 down-regulation was asso...

Hepatic and renal cytochrome p450 gene regulation during citrobacter rodentium infection in wild-type and toll-like receptor 4 mutant mice.

Citrobacter rodentium is the rodent equivalent of human enteropathogenic Escherichia coli infection. This study investigated regulation of hepatic and renal cytochrome P450 (P450) mRNAs, hepatic P450 proteins, cytokines, and acute phase proteins during C. rodentium infection. Female C3H/HeOuJ (HeOu) and C3H/HeJ (HeJ) mice [which lack functional toll-like receptor 4 (TLR4)] were infected with C....

Hepatic flavin-containing monooxygenase gene regulation in different mouse inflammation models.

The objective of the study was to investigate the regulation of hepatic flavin-containing monooxygenases (Fmo) Fmo1, Fmo3, Fmo4, and Fmo5 in three different mouse models of inflammation, including treatment with Citrobacter rodentium, lipopolysaccharide (LPS), and dextran sulfate sodium (DSS). Quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR) was used to evaluate t...
