Serine proteases are implicated in a variety of processes during neurogenesis, including cell migration, axon outgrowth, and synapse elimination. Tissue-type plasminogen activator and urokinase-type activator are expressed in the floor plate during embryonic development. F-spondin, a gene also expressed in the floor plate, encodes a secreted, extracellular(More)
Many natural chemicals in food are in the nanometer size range, and the selective uptake of nutrients with nanoscale dimensions by the gastrointestinal (GI) tract is a normal physiological process. Novel engineered nanomaterials (NMs) can bring various benefits to food, e.g., enhancing nutrition. Assessing potential risks requires an understanding of the(More)
Methylazoximethanol (MAM) acetate-induced cell death in the external granule cell layer of the developing cerebellum affects clusters of cells with morphological features of apoptosis. This is accompanied by selective induction of active caspase-3 expression and increased c-Jun/AP-1 (N) immunoreactivity in dying cells, as revealed with immunohistochemistry.(More)
