Nerve growth factor (NGF) is a trophic and survival factor for cholinergic neurons, and it induces the expression of several genes that are essential for synthesis and storage of acetylcholine (ACh), specifically choline acetyltransferase, vesicular ACh transporter (VAChT), and choline transporter. We have found previously that the phosphatidylinositol(More)
Synthesis, storage and release of acetylcholine (ACh) require the expression of several specialized enzymes, including choline acetyltransferase (ChAT), vesicular acetylcholine transporter (VAChT) and the high-affinity choline transporter (CHT). Extracellular factors that regulate CHT expression and their signaling pathways remain poorly characterized.(More)
MOTIVATION The reconstruction of metabolic networks at the genome scale has allowed the analysis of metabolic pathways at an unprecedented level of complexity. Elementary flux modes (EFMs) are an appropriate concept for such analysis. However, their number grows in a combinatorial fashion as the size of the metabolic network increases, which renders the(More)
