Primary aldosteronism (PA), characterized by autonomous aldosterone overproduction, is a major cause of secondary hypertension with significant cardiovascular complications. Current treatments mainly focus on symptom management rather than addressing underlying mechanisms. This study aims to discover novel therapeutic targets for PA using integrated bioinformatics and experimental validation approaches. We employed systematic approach combining: gene identification through transcriptome-wide association studies (TWAS); causal inference summary data-based Mendelian randomization (SMR) two-sample (MR) analyses; additional analyses included phenome-wide analysis, enrichment protein-protein interaction (PPI) networks, drug repurposing, molecular docking clinical aldosterone-producing adenomas (APAs) tissue. Through screening prioritization, we identified 163 PA-associated genes, which seven emerged as potential targets: CEP104, HIP1, TONSL, ZNF100, SHMT1, two long non-coding RNAs (AC006369.2 MRPL23-AS1). SHMT1 was the most promising target, showing significantly elevated expression in APAs compared adjacent non-tumorous tissues. Drug repurposing analysis four SHMT1-targeting compounds (Mimosine, Pemetrexed, Leucovorin, Irinotecan), supported studies. The integration multiple methods successfully hyperaldosteronism. particular, represents candidate future development. These findings provide new opportunities developing causative PA, though further warranted.

Diabetes is associated with increased risk for kidney disease, heart failure, and mortality. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) prevent these adverse outcomes; however, the mechanisms involved are not clear. We generated a roadmap of metabolic alterations that occur in different organs diabetes response to SGLT2i. In vivo labeling 13C-glucose normoglycemic diabetic mice treated or without dapagliflozin, followed by metabolomics flux analyses, showed that, diabetes, glycolysis glucose oxidation impaired kidney, liver, heart.
