Successful experiments involving the production of transgenic mice by pronuclear microinjection are currently limited by low efficiency of random transgene integration into the mouse genome. Furthermore, not all transgenic mice express integrated transgenes, or in other words are effective as functional transgenic mice expressing the desired product of the transgene, thus allowing accomplishmen...

In the present study, we investigated dopaminergic and steroid hormone systems of A/J mice fed environmentally relevant concentrations a perfluoroalkyl substance (PFAS) mixture over period 10 weeks. The PFAS was chosen based on measured in earthworms at Norwegian skiing area (Trondheim) consisted eight different PFAS. Dietary exposure to led lower total brain dopamine (DA) male mice, as compare...

The PRAME tumor antigen is a potential target for immunotherapy. We assessed the immunogenicity, the antitumor activity, and the safety and the tolerability of a recombinant PRAME protein (recPRAME) combined with the AS15 immunostimulant (recPRAME+ AS15) in preclinical studies in mice and Cynomolgus monkeys. Four groups of 12 CB6F1 mice received 4 injections of phosphate-buffered saline (PBS), ...

the most popular animal models of alzheimer’s disease (ad) are transgenic mice expressing human genes with known mutations which do not represent the most abundant sporadic form of the disease. an increasing number of genetic, vascular and psychosocial data strongly support that the octodon degus, a moderate-sized and diurnal precocial rodent, provides a naturalistic model for the study of the ...

objective: escherichia coli (e.coli) o157:h7 is one of the most important pathogenic causes of hemorrhagic colitis in humans. cattle are the main reservoirs of this bacteria and vaccination is a key mechanism for its control. the intimin, translocated intimin receptor (tir), and espa proteins are virulence factors expressed by the lee locus of enterohemorrhagic e. coli. espa protein is a member...

We analyzed the binding of an influenza matrix protein-derived peptide, MAT(17-31), to cell surface and purified DR1. The pH dependence of peptide binding was dramatically influenced by the membrane environment. Cell surface binding was enhanced at low pH, with little or no binding detected at neutral pH and optimal binding at pH 4. By contrast, hydrogen ion concentration had minimal effect on ...
