PR:PROJECT_SUMMARY Polycystic Kidney Disease (PKD) is a genetic disorder characterized by bilateral PR:PROJECT_SUMMARY cyst formation. We showed that PKD cells and kidneys display metabolic PR:PROJECT_SUMMARY alterations, including the Warburg effect and glutaminolysis, sustained in vitro PR:PROJECT_SUMMARY by the enzyme asparagine synthetase (ASNS). Here, we used antisense PR:PROJECT_SUMMARY oligonucleotides (ASO) against ASNS in orthologous and slowly progressive PKD PR:PROJECT_SUMMARY murine models and show that treatment leads to a drastic reduction of total PR:PROJECT_SUMMARY kidney volume (measured by MRI) and a prominent rescue of renal function in the PR:PROJECT_SUMMARY mouse. Mechanistically, the upregulation of an ATF4-ASNS axis in PKD is driven PR:PROJECT_SUMMARY by the amino acid response (AAR) branch of the integrated stress response (ISR). PR:PROJECT_SUMMARY Metabolic profiling of PKD control kidneys treated with ASNS-ASO or Scr-ASO PR:PROJECT_SUMMARY revealed major changes in the mutants, several of which are rescued by ASNS PR:PROJECT_SUMMARY silencing in vivo. Indeed, ASNS drives glutamine-dependent de novo pyrimidine PR:PROJECT_SUMMARY synthesis and proliferation in cystic epithelia. Notably, while several PR:PROJECT_SUMMARY metabolic pathways were completely corrected by ASNS-ASO, glycolysis was only PR:PROJECT_SUMMARY partially restored. Accordingly, combining the glycolytic inhibitor 2DG with PR:PROJECT_SUMMARY ASNS-ASO further improved efficacy. Our studies identify a new therapeutic PR:PROJECT_SUMMARY target and novel metabolic vulnerabilities in PKD. Of interest, in these tracing PR:PROJECT_SUMMARY studies we could confirm that the pyrimidine biosynthesis pathway is increased PR:PROJECT_SUMMARY and rescued by silencing of Asns.
