Mice have two Otx genes, Otx1 and Otx2. Prior to gastrulation, Otx2 is expressed in the epiblast and visceral endoderm. As the primitive streak forms, Otx2 expression is restricted to the anterior parts of all three germ layers. Otx1 expression begins at the 1 to 3 somite stage in the anterior neuroectoderm. Otx2 is also expressed in cephalic mesenchyme.(More)
Immunocytochemical studies clearly showed that amyloid beta-protein (A beta) deposits are widely distributed in the subcortical regions as well as the cortices of normal aged and Alzheimer disease (AD) brains. To investigate the temporal profile of A beta accumulation in the subcortical region, we quantitated A beta40 and A beta42 levels, using sensitive(More)
