However, the molecular programs underlying progressive organ injury remain poorly defined. Here, we present a longitudinal multiorgan transcriptomic atlas of salt-induced hypertensive injury. We profiled kidney cortex, kidney medulla, heart, and liver across 4 stages, spanning early hypertension to advanced pathology in Dahl salt-sensitive rats. We identified dynamic and tissue-specific molecular trajectories, including a shared early proliferative response that converges on proinflammatory and fibrotic remodeling. Notably, we uncovered compartment-specific renal responses, showing that the cortex and medulla, despite their proximity, follow distinct molecular trajectories during disease progression. We further identified 79 stage- and tissue-specific transcription factors that drive gene expression dynamics in salt-induced hypertensive injury. Integration with human genome-wide association studies revealed conserved pathways in endocrine signaling, ion transport, lipid metabolism, and detoxification, establishing cross-species relevance and highlighting mechanistic targets of clinical importance. Compound-transcriptome analysis revealed stage- and organ-specific therapeutic opportunities, prioritizing kinase and epigenetic modulators as candidates to rebalance maladaptive gene programs. Overall, this study provides a resource for understanding molecular mechanisms from early salt-induced hypertension to tissue-specific injury and underscores the need for precision interventions.<\/jats:p>","DOI":"10.1172\/jci.insight.200841","type":"journal-article","created":{"date-parts":[[2026,4,23]],"date-time":"2026-04-23T16:01:42Z","timestamp":1776960102000},"source":"Crossref","is-referenced-by-count":3,"title":["Longitudinal multiorgan transcriptomic atlas of salt-induced hypertension"],"prefix":"10.1172","volume":"11","author":[{"given":"Ratnakar","family":"Tiwari","sequence":"first","affiliation":[{"name":"Department of Molecular Pharmacology and Physiology, University of South Florida, Tampa, Florida, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olha","family":"Kravtsova","sequence":"additional","affiliation":[{"name":"Department of Molecular Pharmacology and Physiology, University of South Florida, Tampa, Florida, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2329-0931","authenticated-orcid":true,"given":"Lashodya V.","family":"Dissanayake","sequence":"additional","affiliation":[{"name":"Department of Molecular Pharmacology and Physiology, University of South Florida, Tampa, Florida, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa","family":"Lowe","sequence":"additional","affiliation":[{"name":"Department of Molecular Pharmacology and Physiology, University of South Florida, Tampa, Florida, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Biyang","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Molecular Pharmacology and Physiology, University of South Florida, Tampa, Florida, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladislav","family":"Levchenko","sequence":"additional","affiliation":[{"name":"Department of Molecular Pharmacology and Physiology, University of South Florida, Tampa, Florida, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven","family":"Didik","sequence":"additional","affiliation":[{"name":"Department of Molecular Pharmacology and Physiology, University of South Florida, Tampa, Florida, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruslan","family":"Bohovyk","sequence":"additional","affiliation":[{"name":"Department of Molecular Pharmacology and Physiology, University of South Florida, Tampa, Florida, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4832-4170","authenticated-orcid":true,"given":"Daria V.","family":"Ilatovskaya","sequence":"additional","affiliation":[{"name":"Department of Physiology, Medical College of Georgia, Augusta University, Augusta, Georgia, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oleg","family":"Palygin","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Nephrology, Medical University of South Carolina, Charleston, South Carolina, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5190-8356","authenticated-orcid":true,"given":"Alexander","family":"Staruschenko","sequence":"additional","affiliation":[{"name":"Department of Molecular Pharmacology and Physiology, University of South Florida, Tampa, Florida, USA."},{"name":"Hypertension and Kidney Research Center, University of South Florida, Tampa, Florida, USA."},{"name":"James A.
