Interaction of just 2 genes governs coloration patterns in mice
...ed. In this paper, we identify the genetic changes producing
a simple color pattern that helps camouflage mice inhabiting the sandy dunes of Florida's Gulf and Atlantic coasts. These 'beach mice' have evolved a lighter pigmentation than their mainland relatives, a coloration that helps camouflage them from pre...
Abnormal fat metabolism underlies heart problems in diabetic patients
...se children have mutations that prevent cells from producing
enough cardiolipin. The connection between cardiolipin and heart disease in Barth syndrome led the Washington University researchers to wonder if cardiolipin was also affected in diabetic hearts. But in order to measure cardiolipin, the researchers n...
Antioxidant overload may underlie a heritable human disease
...its reduced, antioxidant formsoon got out of hand, producing
excess levels of the reduced glutathione and a condition of reductive stress. Moreover, they showed that the offspring of the heart-diseased animals and mice with lower levels of one of the antioxidant enzymes, glucose-6-phosphate dehydrogenase (G6...
Acute sleep deprivation leads to changes in nighttime urine production for men and women

Inflammation may cause preterm labor and fetal deaths
...study on these two receptors as a possible link in producing
the inflammatory response that is believed to have brought about the fetal death in mice. In a prior mouse study at Case Western Reserve, the investigators noted that inflammation closely paralleled localization of bacteria. In the present study...
