The effects of a transient exposure to hydrogen peroxide (10 min at 200 microM H(2)O(2)) on pancreatic beta cell signal transduction and insulin secretion have been evaluated. In rat islets, insulin secretion evoked by glucose (16.7 mM) or by the

During apoptosis, the mitochondrial membrane potential (MMP) decreases, but it is not known how this relates to the apoptotic process. It was recently suggested that cytochrome c is compartmentalized in closed cristal regions and therefore, matrix remodeling is required to
Amino acid uptake by the general amino acid permease (Aap) of Rhizobium leguminosarum strain 3841 was severely reduced by the presence of aspartate in the growth medium when glucose was the carbon source. The reduction in transport by the Aap
Evidence is presented showing that a neuronal isoform of nitric oxide synthase (NOS) is expressed in rat pancreatic islets and INS-1 cells. Sequencing of the coding region indicated a 99.8% homology with rat neuronal NOS (nNOS) with four mutations, three
Novel primaquine (PQ) and halogenaniline asymmetric fumardiamides 4a⁻f, potential Michael acceptors, and their reduced analogues succindiamides 5a⁻f were prepared by simple three-step reactions: coupling reaction between PQ and mono-ethyl fumarate (1a) or mono-methyl succinate (1b), hydrolysis of PQ-dicarboxylic acid mono-ester
