It is not clear however whether the induction of iNOS and its subsequent utilisation of l-arginine for NO synthesis contribute to the enhancement in l-arginine transport rates observed following induction of cells with pro-inflammatory mediators. To address this issue, we have transfected an iNOS construct in a pEGFP-N1 vector into HEK-293 cells and investigated the effects this has on l-arginine transport. The expression of iNOS through transfection resulted in the production of significant quantities of NO as detected by the standard Griess assay. Under these conditions, the transport of l-arginine was found to be unaltered, with rate of uptake being comparable in both transfected and non-transfected cells. Characterisation of the transporter(s) involved with uptake of l-arginine revealed features characteristic of the classical cationic amino acid transport system y(+). Further analysis of the expression profile of the cationic amino acid transporter (CAT) involved revealed the presence of transcripts for CAT-1 and CAT-2B. These data demonstrate that iNOS activity does not drive or enhance l-arginine transport despite the fact that HEK-293 cells transport l-arginine via the CATs, including CAT-2B which is thought to be critical for supply of substrate to iNOS."xsd:string |
