These parasites constitute a significant risk to humans and animals. They cause self-limited diarrhea in immunocompetent hosts and a life threatening disease in immunocompromised hosts. Interestingly, Cryptosporidium parvum has been related to digestive carcinogenesis in humans. Consistently with a potential tumorigenic role of this parasite, in an original reproducible animal model of chronic cryptosporidiosis based on dexamethasone-treated or untreated adult SCID mice, we formerly reported that C. parvum (strains of animal and human origin) is able to induce digestive adenocarcinoma even in infections induced with very low inoculum. The aim of this study was to further characterize this animal model and to explore metabolic pathways potentially involved in the development of C. parvum-induced ileo-caecal oncogenesis. We searched for alterations in genes or proteins commonly involved in cell cycle, differentiation or cell migration, such as \u03b2-catenin, Apc, E-cadherin, Kras and p53. After infection of animals with C. parvum we demonstrated immunohistochemical abnormal localization of Wnt signaling pathway components and p53. Mutations in the selected loci of studied genes were not found after high-throughput sequencing. Furthermore, alterations in the ultrastructure of adherens junctions of the ileo-caecal neoplastic epithelia of C. parvum infected mice were recorded using transmission electron microscopy. In conclusion, we found for the first time that the Wnt signaling pathway, and particularly the cytoskeleton network seems to be pivotal for the development of C. parvum-induced neoplastic process and cell migration of transformed cells. Furthermore, this model is a valuable tool to contribute to the comprehension of the host-pathogen interactions associated to the intricate infection process due to this parasite, which is able to modulate host cytoskeleton activities and several host-cell biological processes and that remains a significant cause of infection worldwide.<\/jats:p>","DOI":"10.1242\/dmm.013292","type":"journal-article","created":{"date-parts":[[2014,3,21]],"date-time":"2014-03-21T02:52:54Z","timestamp":1395370374000},"source":"Crossref","is-referenced-by-count":32,"title":["<i>Cryptosporidium parvum<\/i>-induced ileo-caecal adenocarcinoma and WNT signaling in a rodent model"],"prefix":"10.1242","author":[{"given":"Sadia","family":"Benamrouz","sequence":"first","affiliation":[{"name":"Ecologie & Biodiversit\u00e9, Universit\u00e9 Catholique de Lille, Lille, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valerie","family":"Conseil","sequence":"additional","affiliation":[{"name":"Ecologie & Biodiversit\u00e9, Universit\u00e9 Catholique de Lille, Lille, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Magali","family":"Chabe","sequence":"additional","affiliation":[{"name":"BDEEP, CIIL, Institut Pasteur de Lille, Lille, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marleen","family":"Praet","sequence":"additional","affiliation":[{"name":"Academic Department of Pathology, Ghent University, Ghent, Belgium;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christophe","family":"Audebert","sequence":"additional","affiliation":[{"name":"Gene Diffusion, Douai, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renaud","family":"Blervaque","sequence":"additional","affiliation":[{"name":"Transcriptomic and Applied Genomic (TAG), CIIL, IPL, Lille, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karine","family":"Guyot","sequence":"additional","affiliation":[{"name":"BDEEP, CIIL, Institut Pasteur de Lille, Lille, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sophie","family":"Gazzola","sequence":"additional","affiliation":[{"name":"BDEEP, CIIL, Institut Pasteur de Lille, Lille, France;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anthony","family":"Mouray","sequence":"additional","affiliation":[{"name":"Plateforme d'Experimentations et de Hautes Technologies Animales, Inst.
