AP-1 Network Project

HNF1alpha, HNF1beta and AP1 in the dynamic gut epithelium.
One of the most fascinating model systems for studying processes of cell proliferation, differentiation, and migration is the gut epithelium. To date, it is known that several transcription factors regulate proliferation or differentiation into the intestine (Blache et al., 2004; Boudreau et al., 2002; Mann et al., 1999).
The gut epithelium also expresses Hepatocyte nuclear factor1 alpha (HNF1alpha), hepatocyte nuclear factor1 beta (HNF1beta) and activator protein-1 (AP-1).
HNF1alpha and HNF1beta are transcription factors that are coexpressed in polarized epithelia of liver, kidney, and digestive tract. The inactivation of the two HNF1 genes has revealed that they are involved in the control of cell proliferation and differentiation during organogenesis and development. HNF1alpha-deficient mice are born normally, but suffer from hepatic, pancreatic and renal functional defects (Pontoglio et al., 1996; Pontoglio et al., 1997; Pontoglio et al., 1998; Lee et al., 1998; Pontoglio et al., 2001). On the other hand, HNF1beta-deficient embryos die early, between 6.5 and 7.5 days post coitum (dpc) because of defective differentiation of extra-embryonic visceral endoderm (Barbacci et al., 1999; Coffinier et al., 1999). Liver-specific HNF1beta-deficient mice present a drastically reduced number of bile ducts and multilayered epithelial structures in the few residual large bile ducts (Coffinier et al., 2002). Mice with a renal-specific inactivation of the HNF1beta gene develop polycystic kidney disease (Gresh et al., 2004). To date, the animal models produced by inactivation of HNF1alpha or HNF1beta genes (using null or conditional knock-out strategies) strongly suggest an involvement of the two genes in proliferation and differentiation of specific cells during organogenesis and development. In addition, biallelic inactivation of HNF1alpha or HNF1beta in human is associated with hyperproliferation and cancer (Bluteau et al., 2002; Zucman-Rossi, 2004).


AP-1 plays a central role in the decision whether a given cell divides, stays alive or dies. AP-1 is composed of Jun family members (C-JUN, JUNB, and JUND) that can form either homo- or heterodimers among themselves or with the Fos family members (C-FOS, FOSB, FRA1, FRA2). The different AP-1 dimers exhibit rather similar DNA binding specificities but differ in their transactivation efficiencies (reviewed in Wagner, 2001). C-JUN and FRA-1 are target genes of the beta-catenin–T cell-factor lymphoid-enhancer factor (beta-catenin/TCF) complex which is the transcriptional component of the Wnt pathway, one of the most relevant in the physiology of gut epithelium (Mann et al., 1999). Interestingly, apoptosis triggered by butyric acid involves transcriptional stimulation of the Bax gene via activation of the JNK/AP1 pathway in colonic epithelial cells (Mandal et al., 2001). In addition, interleukin 2 (IL-2) had an anti-proliferative effect in a human colon adenocarcinoma line (HT-29 D4) and of an untransformed rat intestinal cell clone (IEC-6) in vitro. IL-2 enhances the expression of JUN and FOS (Taheri et al., 1993).

The aim of this proposed project is to study a potential cross-talk or hierarchic relation between HNF1alpha, HNF1beta and AP1 in the renewal and maintenance of the intestine architecture. To this end, we will analyze the gut phenotype of mice deficient for either HNF1alpha or HNF1beta. Since we cannot rule out a possible redundancy between the two proteins, we will also generate double mutants.
We have preliminary evidence that deletion of both HNF1alpha and HNF1beta in the gut epithelium lead to defective differentiation of enterocytes and/or to an increase in proliferation. By following nuclear localization of beta-catenin, we will analyze the Wnt pathway in the mouse models produced. Since C-JUN is a target gene of the beta-catenin/TCF complex, we will analyze the specific expression of C-JUN, both at mRNA and protein level, in the HNF1 mouse models produced.
We will also analyze the expression of other members of the AP1 family as well as follow the activation of the JNK and p38 pathways. If an increased level of AP1 proteins will be observed we will cross HNF1alpha- or HNF1beta-deficient mice with mice carrying floxed alleles for C-JUN or other AP1 family members. In this way, we will obtain data on the contribution of C-JUN (or other AP1 members) to the process of colon differentiation and/or hyperproliferation.
