NettetCYP content was also not increased in kidney microsomes of 2-month-old homozygous mice (data not shown). The induction of CYP was confirmed in 2-month-old mice by immunoblot analysis with antibodies specific for various CYP subfamilies . Quantitative immunoblot analysis revealed that there was a 1-fold increase in the levels of CYP1A, … Nettet1. mai 2011 · NP-mediated Cyp3a induction from three human hepatocyte donors was not significant, confirming that hPXR is not very sensitive to NP-mediated CYP induction. Lastly, mice with PXR (mPXR and hPXR) showed lower NP serum concentrations than PXR-null mice treated with NP suggesting that PXR plays a role in decreasing liver …

NettetNational Center for Biotechnology Information NettetThe fasting-induced response in Cyp4a10 mRNA content was different between lox/lox and LKO mice, while the absence of PGC-1α had no effect on the fasting-induced response for the other Cyp’s. Moreover, the fasting-induced response in mRNA content of Sirtinus 1 and Perilipin 2 was different between lox/lox and LKO mice.
Nettet1. mai 2011 · CYPs were not induced in PXR-null mice, demonstrating that PXR is necessary for NP-mediated CYP induction. CAR-mediated CYP induction was not observed in the PXR-null mice despite previous data demonstrating that NP is also a CAR activator. hPXR mice only showed moderate Cyp induction, suggesting that hPXR is … NettetHydroquinone (1,4-benzenediol) has been widely used in clinical situations and the cosmetic industry because of its depigmenting effects. Most skin-lightening hydroquinone creams contain 4%–5% hydroquinone. We have investigated the role of resveratrol in prevention of hydroquinone induced cytotoxicity in mouse primary hepatocytes. We …
