Our objective was to assess TNS4 expression in intestinal adenomas and determine whether TNS4 is upregulated by Wnt signalling. Apc<jats:sup>Min\/+<\/jats:sup> mice (n\u00a0=\u00a011) were sacrificed at approximately 120\u00a0days old at the onset of anaemia signs. Small intestines were harvested, and Swiss roll preparations were tested for TNS4 expression by immunohistochemistry (IHC). Individual polyps were also separately collected (n\u00a0=\u00a014) and tested for TNS4 mRNA expression and <jats:italic>Kras<\/jats:italic> mutation. The relationship between Wnt signalling and TNS4 expression was tested by Western blotting in the human CRC cell line HCT116 after inhibition of \u03b2\u2010catenin activity with MSAB or its increase by transfection with a Flag \u03b2\u2010catenin expression vector. Overall, 135\/148 (91.2%) of the total intestinal polyps were positive for TNS4 expression by IHC, whilst adjacent normal areas were negative. RT\u2010qPCR analysis showed approximately 5\u2010fold upregulation of TNS4 mRNA in the polyps compared to adjacent normal tissue and no <jats:italic>Kras<\/jats:italic> mutations were detected. In HCT116, \u03b2\u2010catenin inhibition resulted in reduced TNS4 expression, and conversely, \u03b2\u2010catenin overexpression resulted in increased TNS4 expression. In conclusion, this is the first report linking aberrant Wnt signalling to upregulation of TNS4 both during initiation of intestinal adenomas in mice and in in vitro models. The exact contribution of TNS4 to adenoma development remains to be investigated, but the <jats:italic>Apc<\/jats:italic><jats:sup>Min\/+<\/jats:sup> mouse represents a good model to study this.<\/jats:p>","DOI":"10.1111\/iep.12352","type":"journal-article","created":{"date-parts":[[2020,6,22]],"date-time":"2020-06-22T11:54:44Z","timestamp":1592826884000},"page":"80-86","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Tensin4
