. Truncated mouse adenomatous polyposis coli reduces connexin32 content and increases matrilysin secretion from Paneth cells. Eur J Cancer. 2004;40:1599-603 pubmed
..Absence of matrilysin in Min mice reduces adenoma development. Reduced Cx32 and increased matrilysin secretion from Paneth cells could be important to neoplastic development in the intestine. ..
Husøy T, Knutsen H, Løberg E, Alexander J. Intestinal adenomas of Min-mice lack enterochromaffin cells, and have increased lysozyme production in non-Paneth cells. Anticancer Res. 2006;26:1797-802 pubmed
..Altered cell differentiation in adenomas might be caused by different response to Wnt-signalling, while an increased number of enterochromaffin cells in the large intestine is rather an effect of a heterozygous Apc(Min) mutation. ..

. Reducing added sugar intake in Norway by replacing sugar sweetened beverages with beverages containing intense sweeteners - a risk benefit assessment. Food Chem Toxicol. 2008;46:3099-105 pubmed publisher
..The highest intake of benzoic acid was observed for 1- to 2-year-old children, and benzoic acid intake in Norwegian children is therefore considered to be of special concern. ..

..Tumor development in Min mice was not affected. Overall, the tumorigenic potential of DMF in a metabolically competent mouse model was not convincing. ..

..The liver was the least affected organ in wild-type mice, whereas it was the most affected organ in hSULT mice with a 14-fold higher adduct level. ..

..Reduction in GJIC and Cx43 level in IMCE cells may be caused by reduced Cx43 transport as a result of alterations in microtubule function. ..

. An in vitro study on the genotoxic effect of substituted furans in cells transfected with human metabolizing enzymes: 2,5-dimethylfuran and furfuryl alcohol. Mutagenesis. 2016;31:597-602 pubmed publisher
..The results suggest that DNA damage in V79 cells from exposure to DMF detected by the alkaline SCGE assay is independent of human CYP2E1 and SULT1A1, and the genotoxic effect of FFA, as assessed by SCGE, is minimal in V79 cells. ..
