BACKGROUND: A possible mechanism of cyclosporine (CsA) nephrotoxicity is tubular apoptosis. Endoplasmic reticulum (ER) stress has been shown to be an apoptosis activator. Glucose-regulated proteins 78 and 94 (GRP78, GRP94, respectively) are ER stress-induced chaperones. Eukaryotic translation initiation factor 2α (EIF2α) attenuates protein synthesis. If stress is prolonged, cells undergo ...

Abstract S-adenosyl-L-methionine (SAM) is an intermediate metabolite of methionine and serves as the methyl donor for many biological methylation reactions. The synthesis of SAM is catalyzed by SAM synthetase (SAMS), which transfers the adenosyl moiety of adenosine-5'-triphosphate to methionine. In the nematode Caenorhabditis elegans, four sams family genes, sams-1, -3, ...
