A new trick for an old dog? Myocardial-specific roles for prostaglandins as mediators of ischemic injury and repair

Am J Physiol Heart Circ Physiol. 2021 Jun 1;320(6):H2169-H2184. doi: 10.1152/ajpheart.00872.2020. Epub 2021 Apr 16.

Abstract

The small lipid-derived paracrine signaling molecules known as prostaglandins have been recognized for their ability to modulate many facets of cardiovascular physiology since their initial discovery more than 85 years ago. Although the role of prostaglandins in the vasculature has gained significant attention across time, a handful of historical studies have also directly implicated the cardiomyocyte in both prostaglandin synthesis and release. Recently, our understanding of how prostaglandin receptor modulation impacts and contributes to myocardial structure and function has gained attention while leaving most other components of myocardial prostaglandin metabolism and signaling unexplored. This mini-review highlights both the key historical studies that underpin modern prostaglandin research in the heart, while concurrently presenting the latest findings related to how prostaglandin metabolism and signaling impact myocardial injury and repair.

Keywords: Bnip3; heart; prostaglandin.
