Аннотация: Sulfate (SO42 -) plays an important role in mammalian growth and development. The NaS1 sulfate transporter mediates renal sulfate reabsorption and regulates serum sulfate levels. Genetic sequencing of the NaS1 gene (SLC13A1) in a family with hyposulfataemia found NaS1 variants R12X and N174S. Hyposulfataemic NaS1 null (Nas1-/-) mice were found to live longer and have less tumors in aged mice. Median life spans increased (by ≈25%) in male and female Nas1-/- mice when compared with Nas1+/+ mice. Increased hepatic mRNA expression of genes involved in aging: Sirt1 (by ≈60%), Cat (by ≈48%), Hdac3 (by ≈22%), Trp53 and Cd55 (by ≈36%) were detected in Nas1-/- mice. Histological analyses of livers from 2-year-old mice revealed neoplasms in >50% of Nas1+/+ mice but not in Nas1-/- mice. This is the first study to identify hyposulfataemia in humans with NaS1 sequence variants. Furthermore, we identified an extended lifespan, a decreased incidence of spontaneous hepatic tumors and increased hepatic mRNA levels of 5 genes involved in aging in the Nas1-/- mouse, indicating that NaS1 may play role in longevity and cancer. © 2010 Elsevier Inc.
