A Klf5 floxed allele was efficiently deleted from the intestinal epithelium by a Cre transgene under control of the Shh promoter resulting in the inhibition of villus morphogenesis and epithelial differentiation. Although proliferation of the intestinal epithelium was maintained, the expression of Elf3, Pparγ, Atoh1, Ascl2, Neurog3, Hnf4α, Cdx1, and other genes associated with epithelial cell differentiation was inhibited in the Klf5-deficient intestines. At E18.5, Klf5(Δ/Δ) fetuses lacked the apical brush border characteristic of enterocytes, and a loss of goblet and enteroendocrine cells was observed. The failure to form villi was not attributable to the absence of HH or PDGF signaling, known mediators of this developmental process. Klf5-deletion blocked the decrease in FoxA1 and Sox9 expression that accompanies normal villus morphogenesis. KLF5 directly inhibited activity of the FoxA1 promoter, and in turn FOXA1 inhibited Elf3 gene expression in vitro, linking the observed loss of Elf3 with the persistent expression of FoxA1 observed in Klf5-deficient mice. Genetic network analysis identified KLF5 as a key transcription factor regulating intestinal cell differentiation and cell adhesion. These studies indicate a novel requirement for KLF5 to initiate morphogenesis of the early endoderm into a compartmentalized intestinal epithelium comprised of villi and terminally differentiated cells."xsd:string |
