|Figure 4: SULT2A1 mRNA induction by cholic acid in mouse liver. Sult2A1 mRNAs in mouse livers
were assayed by semi-quantitative RT-PCR. Cholic acid, a primary bile acid, was added
to diet at 1% w/w. Data are for 3 individual mice (6-month-old, male) from the control
and experimental group. Levels of β-actin mRNAs served as the normalization control
(B. Chatterjee & CS Song, unpublished).
