Expression of sodium-dependent purine nucleoside carrier (SPNT) mRNA correlates with nucleoside transport activity in rat liver.

The expression of sodium-dependent purine nucleoside transport (SPNT) mRNA has been studied in physiological situations in which Na+-dependent nucleoside uptake in plasma membrane vesicles from rat liver was induced. Sodium-dependent uridine transport rates were induced in genetically obese Zucker rats, during liver regeneration after partial hepatectomy, and under euglycemic-hyperinsulinemic clamp. A PCR-generated fragment, based on a published SPNT sequence cloned from rat liver, was used as a probe in Northern blot analysis. We show that the hepatic mRNA levels of the putative sodium-dependent transport system SPNT correlate with the sodium-dependent uridine transport rates in plasma membrane vesicles from rat liver. These results suggest that the induction of the sodium-dependent nucleoside transport expressed in liver parenchymal cells involves regulation of SPNT gene expression.[1]
