Circulating Cell And Plasma Microrna Profiles Differ Between Non-St-Segment And St-Segment-Elevation Myocardial Infarction, Jeanine Ward, Nada Esa, Rahul Pidikiti, Jane E. Freedman, John F. Keaney, Kahraman Tanriverdi, Olga Vitseva, Victor R. Ambros, Rosalind Lee, David D. Mcmanus
Circulating Cell And Plasma Microrna Profiles Differ Between Non-St-Segment And St-Segment-Elevation Myocardial Infarction, Jeanine Ward, Nada Esa, Rahul Pidikiti, Jane E. Freedman, John F. Keaney, Kahraman Tanriverdi, Olga Vitseva, Victor R. Ambros, Rosalind Lee, David D. Mcmanus

BACKGROUND: Differences in plasma and whole blood expression microRNAs (miRNAs) in patients with an acute coronary syndrome (ACS) have been determined in both in vitro and in vivo studies. Although most circulating miRNAs are located in the cellular components of whole blood, little is known about the miRNA profiles of whole blood subcomponents, including plasma, platelets and leukocytes in patients with myocardial ischemia. METHODS: Thirteen patients with a ST-segment-elevation (STEMI) or non-ST-segment elevation (NSTEMI) myocardial infarction were identified in the University of Massachusetts Medical Center Emergency Department (ED) or cardiac catheterization laboratory between February and June of 2012. Whole blood …
Gender Differences In The Development Of Uremic Cardiomyopathy Following Partial Nephrectomy: Role Of Progesterone, Christopher Drummond, George Buddny, Steven Haller, Jiang Liu, Yanling Yan, Zijian Xie, Deepak Malhotra, Joseph Shapiro, Jiang Tian
Gender Differences In The Development Of Uremic Cardiomyopathy Following Partial Nephrectomy: Role Of Progesterone, Christopher Drummond, George Buddny, Steven Haller, Jiang Liu, Yanling Yan, Zijian Xie, Deepak Malhotra, Joseph Shapiro, Jiang Tian
Zijian Xie
Gender difference has been suggested as a risk factor for developing cardiovascular and renal diseases in humans and experimental animals. As a major sex hormone, progesterone was reported to compete with cardiotonic steroid binding to Na/K-ATPase. Our previous publication demonstrated that cardiotonic steroids (e.g., marinobufagenin) play an important role in the development of experimental uremic cardiomyopathy. We also observed that the putative mineralocorticoid antagonists, spironolactone and its major metabolite canrenone, antagonize binding of cardiotonic steroids to Na/K-ATPase in a competitive manner and also ameliorate experimental uremic cardiomyopathy induced by partial nephrectomy. In the following studies, we noted that progesterone displayed …

Influenza A virus (IAV) has a segmented genome that allows for the exchange of genome segments between different strains. This reassortment accelerates evolution by breaking linkage, helping IAV cross species barriers to potentially create highly virulent strains. Challenges associated with monitoring the process of reassortment in molecular detail have limited our understanding of its evolutionary implications. We applied a novel deep sequencing approach with quantitative analysis to assess the in vitro temporal evolution of genomic reassortment in IAV. The combination of H1N1 and H3N2 strains reproducibly generated a new H1N2 strain with the hemagglutinin and nucleoprotein segments originating from H1N1 …

Nonenzymatic Glycosylation Of Erythrocyte Membrane Proteins. Relevance To Diabetes, J A. Miller, Ellen M. Gravallese, H F. Bunn

Nonenzymatic glycosylation of proteins of the erythrocyte membrane was determined by incubating erythrocyte ghosts with [3H]borohydride. The incorporation of tritium into protein provides a reliable assay of ketoamine linkages. The membrane proteins from 18 patients with diabetes incorporated twice as much radioactivity as membrane proteins from normal erythrocytes. After acid hydrolysis, amino acid analysis showed that the majority of radioactivity was localized to glucosyllysine. Autoradiograms showed that all of the major proteins of the erythrocyte membrane, separated by electrophoresis on sodium dodecyl sulfate gels, contained ketoamine linkages. No protein bands in either normal or diabetic erythrocytes showed significant preferential labeling. …
