DNA deaminating ability and genotoxicity of nitric oxide and its progenitors

…, M Misra, TM Dunams, TA Cebula, WH Koch… - Science, 1991 - science.org
Nitric oxide (NO), a multifaceted bioregulatory agent and an environmental pollutant, can also
cause genomic alterations. In vitro, NO deaminated deoxynucleosides, deoxynucleotides, …

Seven-transmembrane-spanning receptors and heart function

HA Rockman, WJ Koch, RJ Lefkowitz - Nature, 2002 - nature.com
Understanding precisely how the heart can recognize and respond to many different extracellular
signalling molecules, such as neurotransmitters, hormones and growth factors, will aid …

Cardiac function in mice overexpressing the β-adrenergic receptor kinase or a βARK inhibitor

WJ Koch, HA Rockman, P Samama, RA Hamilton… - Science, 1995 - science.org
Transgenic mice were created with cardiac-specific overexpression of the β-adrenergic

[HTML][HTML] A novel protective effect of erythropoietin in the infarcted heart

…, BH Annex, JS Stamler, WJ Koch - The Journal of …, 2003 - Am Soc Clin Investig
Erythropoietin (EPO) has been shown to protect neurons from ischemic stroke, but can also
increase thrombotic events and mortality rates in patients with ischemic heart disease. We …

Embryonic stem cell–derived exosomes promote endogenous repair mechanisms and enhance cardiac function following myocardial infarction

…, J Elrod, G Qin, SR Houser, WJ Koch… - Circulation …, 2015 - Am Heart Assoc
Rationale: Embryonic stem cells (ESCs) hold great promise for cardiac regeneration but are
susceptible to various concerns. Recently, salutary effects of stem cells have been …

Sequence and Expression of mRNAs Encoding the α1 and α2 Subunits of a DHP-Sensitive Calcium Channel

…, AT Leung, KP Campbell, E McKenna, WJ Koch… - Science, 1988 - science.org

Adrenergic nervous system in heart failure: pathophysiology and therapy

A Lymperopoulos, G Rengo, WJ Koch - Circulation research, 2013 - Am Heart Assoc
Heart failure (HF), the leading cause of death in the western world, develops when a cardiac
injury or insult impairs the ability of the heart to pump blood and maintain tissue perfusion. It …

A novel and efficient model of coronary artery ligation and myocardial infarction in the mouse

…, Q Fan, JK Chuprun, XL Ma, WJ Koch - Circulation …, 2010 - Am Heart Assoc
Rationale: Coronary artery ligation to induce myocardial infarction (MI) in mice is typically

Expression of a β-adrenergic receptor kinase 1 inhibitor prevents the development of myocardial failure in gene-targeted mice

…, J Ross Jr, RJ Lefkowitz, WJ Koch - Proceedings of the …, 1998 - National Acad Sciences
Heart failure is accompanied by severely impaired β-adrenergic receptor (βAR) function,
which includes loss of βAR density and functional uncoupling of remaining receptors. An …

Targeting the Receptor-Gq Interface to Inhibit in Vivo Pressure Overload Myocardial Hypertrophy

…, HA Rockman, G Iaccarino, RJ Lefkowitz, WJ Koch - Science, 1998 - science.org
