Effect of dexamethasone on the expression of LXRβ and PXR.

<p>158N cells were incubated with Dex (1 µM) during 24 h. Total RNA was extracted and real-time PCR experiments were performed using primers recognizing specifically LXRβ or PXR. Results are expressed as the ratio of LXR or PXR expression over 26S. 100% is the level in control cells. They represent the mean +/− SEM of three independent experiments. *p<0.05 when compared to control by using Student's t test.
