Apc inactivation leads to constitutive repression of
Shp and Ibabp and activation of
Cox-2 expression in adjacent colonic mucosa and colon tumors of
ApcMin/+ mice. Bars represent qRT-PCR quantitation
(fold of C57BL/6J) for (A) Shp, (B) Ibabp, and (C)
Cox-2 corrected for Gapdh as an internal control
in NT colonic mucosa and colon tumors from ApcMin/+ and
ApcMin/+
Fxr−/− mice. Values are
means ± SEMs, n = 4 (mean of 6 replicates/mouse). Means without a
common letter differ, P < 0.05. Apc, adenomatous
polyposis coli; Cox-2, cyclooxygenase-2; Fxr,
farnesoid X receptor; Ibabp, ileal bile acid-binding protein; NT,
nontumor; Shp, small heterodimer partner.
