Oxidative stress has the main role in protein conformational changes and consequent direct involvement in different kind of diseases. Potassium sorbate as a widespread industrial preservative and glucose are two important oxidants that can be involved in oxidative stress. In this study the effect of ellagic acid as a phenolic antioxidant on amyloid fibril formation of human serum albumin upon incubation...
Curiosity surrounding the physiological relevance of neural insulin signaling has gradually developed since the discovery that nervous tissue contains both the hormone and its receptor. Similar to other receptor tyrosine kinases, ligand interaction with the insulin receptor (IR) activates a variety of intracellular signaling pathways, particularly those relevant to cellular survival. Consequently,...
Hippocampal CA1 homosynaptic long-term potentiation (LTP) is expressed specifically at activated synapses. Increased insertion of postsynaptic α-amino-3-hydroxy-5-methyl-isoxazole-4-propionic acid receptors (AMPARs) appears to be crucial for CA1 LTP. However, the mechanism underlying AMPAR insertion during LTP remains largely unknown. We now report that phosphatidylinositol 3-kinase (PI3K) is complexed...
