In this way, we show data-based support of our hypothesis, which states that under conditions of food abundance incompetent brain-pull will lead to build-ups in the supply chain culminating in obesity and type 2 diabetes. (frontiersin.org)

C) Semi-quantitative PCR analysis for p27 transcript in the liver of WT and p27Kip1 KO mouse. (koreamed.org)
Here, we show that Wrn(∆hel/∆hel) mice exhibit increased extracellular matrix, defenestration, decreased fenestration diameter, and changes in markers of liver sinusoidal endothelial cell inflammation, consistent with age-related pseudocapilliarization. (nih.gov)
This study reveals that Wrn(∆hel/∆hel) mice have accelerated typical age-related liver changes including pseudocapillarization. (nih.gov)
A histopathological analysis revealed that the biliary tract lesions in the liver appeared to be an intrahepatic cholangiocarcinoma with higher tumor incidence, shorter experimental duration, and a markedly increased incidence in obese mice. (bvsalud.org)

William Castle opens Harvard 's Bussey Institution , where many early mouse geneticists get their start. (jax.org)

Under control conditions (21% O-2) and mild hypoxia (12-15% O-2) no difference of respiratory parameters was observed between adult wildtype (A(1)R(+/+)) and A(1)R(-/-) mice. (uni-regensburg.de)

The first recorded knockout mouse was created by Mario R. Capecchi , Martin Evans , and Oliver Smithies in 1989, for which they were awarded the 2007 Nobel Prize in Physiology or Medicine . (wikipedia.org)
Their existence stems from discoveries made in the 1980's by this year's Nobel Laureates in Physiology or Medicine. (nobelprize.org)

Mice lacking Hv1 (right panels) had a much smaller volume of infarcted tissue than normal mice. (vectorblog.org)

First successful transplantations of ovaries between female mice are performed by William Russell at JAX. (jax.org)

Western analysis also showed elevated levels of dimeric and oligomeric Aβ in brain extracts, both extracellular and intracellular, from CD45-/- PSAPP mice. (alzforum.org)

These mice provided some of the first evidence that susceptibility to cancer can be inherited, just like hair color. (mentalfloss.com)

MyD88 KO (knockout) mice are nearly completely protected against the inflammatory and bronchoconstriction effects induced by acute organic dust extract (ODE) treatments. (cdc.gov)
Upon pharyngeal aspiration, SWCNT elicited typical inflammatory responses in w/t and MPO k/o mice documented by increased production of pro-inflammatory cytokines (TNF-α, IL-6 and MCP-1) 1 day after the exposure ( Fig. 1a, b, c ). (cdc.gov)

Charles Brown At the time of the conference, Victoria Blaho was a graduate student studying a mouse model of Lyme infection in Charles Brown's newly opened lab at the University of Missouri. (asbmb.org)

Mice lacking the tumor suppressors p16(Ink4a) (Cdkn2a, cyclin-dependent kinase inhibitor 2a), p19(Arf) (an alternative reading frame product of Cdkn2a,), and p27(Kip1) (Cdkn1b, cyclin-dependent kinase inhibitor 1b) result in malignant progression of epithelial cancers, sarcomas, and melanomas, respectively. (koreamed.org)
In the present study, we developed a novel mouse model of malignant lesions in the biliary ducts induced by the administration of the carcinogen azoxymethane to obese C57BLKS/J-db/db mice. (bvsalud.org)
