A Glutathione Peroxidase, Intracellular Peptidases and the TOR Complexes Regulate Peptide Transporter PEPT-1 in C. elegans
The intestinal peptide transporter PEPT-1 in Caenorhabditis elegans is a rheogenic H(+)-dependent carrier responsible for the absorption of di- and tripeptides. Transporter-deficient pept-1(lg601) worms are characterized by impairments in growth, development and reproduction and develop a severe obesity like phenotype. The transport function of PEPT-1 as well as the influx of free fatty acids w...
متن کاملHow the Intestinal Peptide Transporter PEPT-1 Contributes to an Obesity Phenotype in Caenorhabditits elegans
BACKGROUND Amino acid absorption in the form of di- and tripeptides is mediated by the intestinal proton-coupled peptide transporter PEPT-1 (formally OPT-2) in Caenorhabditits elegans. Transporter-deficient animals (pept-1(lg601)) show impaired growth, slowed postembryonal development and major changes in amino acid status. PRINCIPAL FINDINGS Here we demonstrate that abolished intestinal pept...
متن کاملRegulation of oligopeptide transporter (Pept-1) in experimental diabetes.
The knowledge of expression and biology of the intestinal oligopeptide transporter (Pept-1) in a metabolic disorder such as diabetes may have nutritional and pharmacological implications. To study this problem, rats were made diabetic by streptozotocin injection, and Western and Northern blot analyses and nuclear run-on assay were used to determine the protein and gene expressions of Pept-1 and...
متن کاملIntracellular Glutathione Levels Regulate Fos/Jun Induction and Activation of Glutathione S-Transferase Gene Expression 1
Induction of glutathione S-transferase Ya and NAD(P)H:quinone reductase gene expression by a variety of chemical agents is mediated by regulatory elements, EpRE and ARE, composed of two adjacent AP-l-like binding sites and activated by Fos/Jun heterodimeric complex (AP-1). Recent studies show that chemical induction of glutathione S transferase Ya and quinone reductase gene expression is associ...
