Glucagon-like peptide-1 (GLP-1) acts via its G protein-coupled receptor (GLP-1R) to regulate blood glucose. Although the GLP-1R is widely expressed in peripheral tissues, including the heart, and exogenous GLP-1 administration increases heart rate and blood pressure in rodents, the physiological importance of GLP-1R action in the cardiovascular system(More)
The ability of gene profiling to predict treatment response and prognosis in breast cancers has been demonstrated in many studies using DNA microarray analyses on RNA from fresh frozen tumor specimens. In certain clinical and research situations, performing such analyses on archival formalin fixed paraffin-embedded (FFPE) surgical specimens would be(More)
Immunohistochemical examination showed no significant expression of platelet-derived growth factor-A (PDGF-A), PDGF-B, PDGF receptors, or of c-myc in the thoracic and abdominal aortas of normal roosters. In cholesterol-fed roosters, intense immunohistochemical reaction for PDGF-B, PDGF receptor, and c-myc was seen in the lipid-rich thickened intimal lesions(More)
Inhibiting activity of the c-Myb transcription factor attenuates G1 to S phase cell cycle transitions in vascular smooth muscle cells (SMCs) in vitro. To determine the effects of arterial SMC-specific expression of a dominant-negative c-Myb molecule (Myb-Engrailed) on vascular remodeling in vivo, we performed carotid artery wire-denudation in 2 independent(More)
OBJECTIVE The IP3 receptor-1 (IP3R1) mediates Ca2+ signals critical to vascular smooth muscle cell (VSMC) proliferation. The cell cycle-associated transcription factor c-Myb increases Ca2+ at the G1/S transition. Here we show the mechanism through which c-Myb regulates expression of IP3R1. METHODS & RESULTS Ribonuclease protection confirmed(More)
BACKGROUND Vascular remodelling is characterized by increased smooth muscle cell (SMC) proliferation and migration. Coincident with these events, SMC markers of differentiation are known to down-regulate in advanced stages of atherosclerosis, a process known as phenotypic modulation. However, it is not known when this first begins. Here we sought to(More)
