Study Title | Urolithin A (UroA) acts at CYP1A1/1B1 substrates leading to enhanced aryl hydrocarbon receptor (AHR) activity in vivo |
Study Summary | Many AHR ligands are CYP1A1/1B1 substrates, which can result in the rapid clearance within the intestinal tract and other tissues, limiting both the level and duration of AHR activation. This leads to the hypothesis that there are dietary constituents capable of inhibiting CYP1A1/1B1 increasing the half-live of potent AHR ligands. To test this hypothesis, we examined the ability of urolithin A (UroA) to act at CYP1A1/1B1 substrates leading to enhanced AHR activity in vivo. |

Sample Preparation:
Sampleprep ID: | SP002577 |
Sampleprep Summary: | 40 µg microsomes isolated from Hepa 1 cells treated with 5 nM TCDD for 24 h, or lung microsomes (100 µg) from mice on the semi-purified diet, were incubated with various compounds and incubation times as indicated. The reactions were carried out at 37°C in an incubator in the presence of NADPH regeneration system and terminated by addition of 800 µL ice cold 100% methanol (v/v) containing 1 µM chlorpropamide as internal standard. Then mixtures were kept in -20°C for 30 mins followed by centrifugation at 12,000 × g for 20 min at 4°C. The supernatants were dried in a under vacuum and reconstituted in 60 μL 50% methanol (v/v). After centrifugation, supernatants were transferred to autosampler vials for LC-MS/MS analysis. |
