Circulation On The Run

Dr. Carolyn Lam:               Welcome to Circulation on the Run your weekly podcast summary and backstage pass to the Journal and it's editors. I'm Dr. Carolyn Lam associate editor from the National Heart Center and Duke National University of Singapore.                                                 Our feature paper this week provides important mechanistic insights into oxidative stress and inflammation with aging. More of that soon right after the summary of this week's journal.                                                 The first paper contributes to our understanding of the genetic and functional relevance of soluble guanylyl cyclase activity for coronary artery disease. As background, a chromosomal locus at 4q32.1 has been associated with coronary artery disease risk with genome wide significance. The locus encompasses GUCY1A3, which encodes the alpha one subunit of the soluble guanylyl cyclase, a key enzyme of the nitric oxide cyclic GMP signaling pathway.
