  sub:_4 prov:value "We therefore analyzed the expression levels of Wnt2, Wnt5a, Bmp2, Bmp4, shh, and ihh by in situ hybridization (E 15.5) and RNase protection assay [E 15.5, postnatal day 4 (P4), P12, and P30] in wild-type and mutant gastrointestinal tract. Although no differences were observed in the expression levels of the Wnt and hedgehog genes, a significant reduction (30% to 40%) was found in the expression levels of Bmp2 in the stomach, duodenum, and jejunum, and for Bmp4 in the stomach (Fig. 12A-C), indicating Bmp2 and Bmp4 as downstream (direct or indirect) targets of Fkh6 action." ;
