Control of Vascular Smooth Muscle Cell Growth by Connexin 43
(2012-06)Connexin 43 (Cx43), the principal gap junction protein in vascular smooth muscle cells (VSMCs), regulates movement of ions and other signaling molecules through gap junction intercellular communication (GJIC) and plays ... -
Coronary Artery Ligation and Intramyocardial Injection in a Murine Model of Infarction
(2011)Mouse models are a valuable tool for studying acute injury and chronic remodeling of the myocardium in vivo. With the advent of genetic modifications to the whole organism or the myocardium and an array of biological and/or ... -
The cyclic GMP modulators YC-1 and zaprinast reduce vessel remodeling through anti-proliferative and pro-apoptotic effects
(East Carolina University, 2009-06)Guanosine-specific cyclic nucleotide signaling is suggested to serve protective actions in the vasculature; however, the influence of selective pharmacologic modulation of cyclic guanosine monophosphate (GMP)-synthesizing ... -
Deciphering the impact of fructose metabolism on liver mitochondrial bioenergetics
(East Carolina University, 2021-12-07)Since its discovery in 1980, the interest in nonalcoholic fatty liver disease, the liver manifestation of metabolic syndrome, has expanded due to the growing impact on the world's health. Commonly characterized by ... -
Deletion of the EphA2 receptor exacerbates myocardial injury and the progression of ischemic cardiomyopathy
(2014-04)EphrinA1-EphA-receptor signaling is protective during myocardial infarction (MI). The EphA2-receptor (EphA2-R) potentially mediates cardiomyocyte survival. To determine the role of the EphA2-R in acute non-reperfused ... -
DINITROBENZENES STIMULATE ELECTRON FLUX WITHIN NEURONAL NITRIC OXIDE SYNTHASE IN THE ABSENCE OF CALMODULIN
(2011)Efficient electron transfer and conversion of L-arginine to L-citrulline and nitric oxide (NO●) by neuronal nitric oxide synthase (nNOS) requires calmodulin (CaM) binding. The present study focused on electron transfer ... -
The effect of fasting on the activation in vivo of the insulin receptor kinase.
(East Carolina University, 1990-02-01)Fasting causes insulin resistance in liver and fat, and increases insulin sensitivity in muscle. We studied the response in vitro and in vivo to insulin of the insulin receptor tyrosine kinase in muscle and liver from 72 ... -
Effects of Aerobic Capacity Phenotype on Adaptive Responses to Ischemic Stress
(East Carolina University, 2009)Ischemic disease leads to increased tissue stress by decreasing supply of nutrients adequate to meet energy demands. To maintain functionality, compensatory mechanisms for diminished vascular supply are induced by numerous ... -
Enhanced Mitochondrial Superoxide Scavenging Does Not Improve Muscle Insulin Action in the High Fat-Fed Mouse
(2015-05)Improving mitochondrial oxidant scavenging may be a viable strategy for the treatment of insulin resistance and diabetes. Mice overexpressing the mitochondrial matrix isoform of superoxide dismutase (sod2tg mice) and/or ... -
EphA2-receptor deficiency exacerbates myocardial infarction and reduces survival in hyperglycemic mice
(2014-08)Background We have previously shown that EphrinA1/EphA expression profile changes in response to myocardial infarction (MI), exogenous EphrinA1-Fc administration following MI positively influences wound healing, and ...
