Collapsin response mediator proteins (CRMPs) are involved in cell differentiation and axonal growth. In this study, we investigated neurite outgrowth and the expression of CRMP-2 in PC12 cells. Nondifferentiated PC12 cells hardly express CRMP-2, but the expression of CRMP-2 increases with neurite outgrowth. We established a stable CRMP-2-overexpressing PC12(More)
Sialylation is essential for development and regeneration in mammals. Using N-propanoylmannosamine, a novel precursor of sialic acid, we were able to incorporate unnatural sialic acids with a prolonged N-acyl side chain (e.g., N-propanoylneuraminic acid) into cell surface glycoconjugates. Here we report that this biochemical engineering of sialic acid leads(More)
The most consistent neurochemical abnormality in Parkinson's disease is degeneration of dopaminergic neurons in the substantia nigra, leading to a reduction of striatal dopamine levels. The rate-limiting step in the biosynthesis of dopamine, noradrenalin, and adrenalin is catalyzed by tyrosine 3-monooxygenase (=tyrosine hydroxylase), which catalyzes the(More)
Neurite outgrowth (e.g. axonal or dendrite outgrowth) of neurons is necessary for the development and functioning of the central nervous system. It is well accepted that the differentiation of neurons and neurite outgrowth involve alterations in gene expression. Furthermore, mitochondria play a role in different aspects of neurite outgrowth. Here we show(More)
