Primary aldosteronism (PA) is the most common form of endocrine hypertension. This study was to investigate the gene expression profile in PA adrenal glands and normal controls using RNA-Sequencing. By performing transcriptome analyses for 3 PA adrenal glands and 3 controls on Illumina platform, we identified 1,093 transcripts as significantly differently expressed genes (DEGs), which provided clues for further study of these transcript changes during PA pathogenesis. Further, Gene Set Enrichment Analysis (GSEA) identified 35 significant Kyoto Encyclopedia of Genes and Genomes (KEGG) biological pathways, including 'ribosome', 'oxidative phosphorylation', 'histidine metabolism', 'xenobiotics metabolism by Cytochrome P450', 'drug metabolism by Cytochrome P450', 'tyrosine metabolism' and 'glutathione metabolism'. In summary, we identified novel genes that are associated with PA phenotype, as well as differently regulated biological pathways relating to protein synthesis, energy acquisition and metabolism. Our study provides new candidates for further elucidation of the molecular mechanisms underlying PA pathogenesis.
