Cholesterol gallstones are associated with slow intestinal transit in humans as well as in animal models, but the molecular mechanism is unknown. We investigated in C57L/J mice whether the components of a lithogenic diet (LD; 1.0% cholesterol, 0.5% cholic acid and 17% triglycerides), as well as distal intestinal infection with Helicobacter hepaticus, influence small intestinal transit time. By ...
Activation of inflammatory gene expression by the transcription factor NF-kB is a central pathway in many inflammatory disorders, including colitis. Increased NF-kB activity has been linked with development of colitis in humans and animal models, thus it was unexpected when NF-kB-deficient mice developed spontaneous typhlocolitis. To further characterize this finding, we induced typhlocolitis i...
Adenosine is a purine metabolite that can mediate anti-inflammatory responses in the digestive tract through the A(2A) adenosine receptor (A(2A)AR). We examined the role of this receptor in the control of inflammation in the adoptive transfer model of colitis. Infection of A(2A)AR(-/-) mice with Helicobacter hepaticus increased colonic inflammation scores compared with uninfected A(2A)AR contro...
On the basis of our 2011 microbiological monitoring tests, we report here the current microbiological status of mice and rats housed in experimental facilities in Japan. We tested more than 14,000 mice, 6,000 serum samples, 500 fecal or cecal samples, and 200 lung samples from 3,549 mouse facilities within Japanese universities and institutes (U/I), pharmaceutical companies and contract researc...
The present study contains information about proper microbiological monitoring of laboratory animals' health and the standardization of microbiological monitoring methods in Korea. Microbiological quality control for laboratory animals, composed of biosecurity and health surveillance, is essential to guard against research complications and public health dangers that have been associated with a...
