Mus musculus mice have been investigated for the total elements content in different organs (lung, liver, spleen, kidney, brain, testicle, heart and muscle) and molecular mass distribution patterns of Mn, Ni, Cu, Zn, As, Pb, Cr, Fe, Co, Se and Cd. Some differences have been found in the organs studied, with especially relevant being the Cu-containing fraction present only in the brain and the As-containing one in the liver. Other differences related to the abundance of the metallospecies have also been found. The present paper is the first step in the study of the “metallome” of this inbred laboratory species from which the genome is completely known. This organism could be used as a model in future studies focused on wild mice and the analytical approach developed could be applied to wild mice to find markers of environmental pollution.

    Molecular analysis of the genome was performed for 14 species of the genus Stachys. RAPD and ISSR analyses of the Stachys genome revealed 574 polymorphic fragments, including genus-and species-specific markers. Based on the patterns, UPGMA and the Jacquard coefficient were used to estimate the...

    Genomic analysis of human hepatocellular carcinoma (HCC) is potentially confounded by the differentiation state of the hepatic cell-of-origin. Here we integrated genomic analysis of mouse HCC (with defined cell-of-origin) along with normal development. We found a major shift in expression of Wnt...

    Previous work has shown that chemically induced oxidative stress disrupts the protein interactions of the E-cadherin/β-catenin/α-catenin complex in precision-cut mouse liver slices (Parrish et al., 1999, Toxicol. Sci. 51, 80–86). Although these data suggest a role for oxidative...
