Abstract:Background and SignificanceRecent evidence suggests aberrant carotid body chemoreceptor (CBC) function contributes to tonic elevation of renal nerve activity and reductions in renal blood flow in chronic heart failure (CHF). These changes combined with anemia and capillary rarefaction likely contribute to tissue hypoxia, and may drive renal fibrosis and attendant dysfunction. Previous work indicates that stable expression of hypoxia‐inducible factor 1‐α (HIF1α) and down regulation of MiR‐155 drive gene program… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
