Prothrombin Deficient Mice.

Prothrombin Deficient Plasma

ASSAY PRINCIPLE: The method is a clotting assay where all the clotting factors are present (constant and in excess, brought by the deficient plasma), excepted for FII, which is brought by the diluted tested plasma, and clotting is triggered with calcium thromboplastin. FII is the limiting factor and clotting time is inversely proportional to the concentration of FII. There is an inverse linear ...

Lessons from Tau-Deficient Mice

Both Alzheimer's disease (AD) and frontotemporal dementia (FTD) are characterized by the deposition of hyperphosphorylated forms of the microtubule-associated protein tau in neurons and/or glia. This unifying pathology led to the umbrella term "tauopathies" for these conditions, also emphasizing the central role of tau in AD and FTD. Generation of transgenic mouse models expressing human tau in...

Characterization of XIAP-deficient mice.

The inhibitor of apoptosis protein (IAP) family consists of a number of evolutionarily conserved proteins that function to inhibit programmed cell death. X-linked IAP (XIAP) was cloned due to its sequence homology with other family members and has previously been shown to prevent apoptosis by binding to active caspases 3, 7, and 9 in vitro. XIAP transcripts can be found in a variety of tissues,...

Hyperaldosteronism in Klotho-deficient mice.

Klotho is a membrane protein participating in the inhibitory effect of FGF23 on the formation of 1,25-dihydroxyvitamin-D(3) [1,25(OH)(2)D(3)]. It participates in the regulation of renal tubular phosphate reabsorption and stimulates renal tubular Ca(2+) reabsorption. Klotho hypomorphic mice (klotho(hm)) suffer from severe growth deficit, rapid aging, and early death, events largely reversed by a...
