The experimental outline is as described in the Fig. 6 legend. (A) Effects of downregulation of hepatic LSD1 on protein occupancy and histone modification at Cyp7a1, Cyp8b1, and Ntcp promoters. (B, C, E, F) Effects of downregulation of LSD1 on expression of the indicated genes detected by q-RTPCR. The mean and SEM (n=3) are plotted and statistical significance was measured using Student’s t-test. *p<0.05, **p<0.01and NS statistically not significant. (D) Expected changes in liver BA flow in LSD1-downregulated mice challenged with a BA overload based on transcriptional changes are illustrated.
