Abstract
Angiotensin receptor-neprilysin inhibitor (ARNI) and angiotensin II receptor blockers (ARB) are antihypertension medications that improve cardiac remodeling and protect the heart. However, at the early stage of hypertension, it is still unclear how these two drugs affect the transcriptomic profile of multiple organs in hypertensive rats and the transcriptomic differences between them. We performed RNA sequencing to define the RNA expressing profiles of the eight tissues (atrium, ventricle, aorta, kidney, brain, lung, white fat, and brown fat) in spontaneously hypertensive rats (SHRs) and SHRs treated with ARNI or ARB. Acquired data was processed and analyzed by computational analyses (i.e., clustering, DEG, functional association, WGCNA, and protein-protein interaction (PPI) network analysis). We discovered that various tissues produced significant transcriptomic changes at the early stage of hypertension. The transcriptomic differences are notably in brown fat, kidney, lung, and brain tissues between ARNI and ARB treatment. Meanwhile, ARNI or ARB treatment can reverse the dysregulated expression genes related to the metabolism process, especially in brown fat, lung, and kidney tissues under hypertension. The current study has presented a comprehensive rat RNA-Seq transcriptomic landscape in SHRs and compared the transcriptome differences between ARNI and ARB treatment as a biomedical research resource for further study.
