BACKGROUND Preconditioning phenomena provide evidence for adaptive responses to ischemia that have important implications for treatment/prevention of myocardial infarction. Hypoxia-inducible factor 1 (HIF-1) mediates adaptive transcriptional responses to hypoxia/ischemia. METHODS AND RESULTS Exposure of wild-type mice to intermittent hypoxia resulted in(More)
Neuropilin-1 (Npn-1) is a receptor that binds multiple ligands from structurally distinct families, including secreted semaphorins (Sema) and vascular endothelial growth factors (VEGF). We generated npn-1 knockin mice, which express an altered ligand binding site variant of Npn-1, and npn-1 conditional null mice to establish the cell-type- and ligand(More)
Subcellular localization of nitric oxide (NO) synthases with effector molecules is an important regulatory mechanism for NO signalling. In the heart, NO inhibits L-type Ca2+ channels but stimulates sarcoplasmic reticulum (SR) Ca2+ release, leading to variable effects on myocardial contractility. Here we show that spatial confinement of specific NO synthase(More)
BACKGROUND Inducible nitric oxide synthase (iNOS, or NOS2) reduces the severity of accelerated graft arteriosclerosis (AGA) in transplanted organs, although the precise mechanism is unclear. METHODS AND RESULTS We transplanted wild-type murine hearts into either wild-type or NOS2-null recipient mice; we then measured cardiac allograft survival and(More)
Autosomal dominant retinocerebral vasculopathy with cerebral leukodystrophy (RVCL) is a rare neurovascular syndrome causing retinal and central nervous system vasculopathy often recognized as contrast-enhancing white matter changes or pseudotumors on imaging. Heterozygous frameshift mutations in the 3-prime repair exonuclease 1 gene have been identified in(More)
Systemic vasculitis (SV) involving abdominal structures usually has a poor prognosis. Gallbladder vasculitis (GV) has been reported as part of SV (GB-SV) and focal single-organ vasculitis (GB-SOV). We analyzed clinical and histologic characteristics of patients with GV to identify features that differentiate GB-SOV from the systemic forms of GV. To identify(More)
Acknowledgements First and foremost, I thank Deborah A. Bolnick, my advisor. This master's report would not have been completed without her guidance. I also thank Enrique R. Rodríguez-Alegría and Lisa Overholtzer for loaning the samples and instructing me in the archaeological aspects of this project. I will always be deeply grateful to the Fundación Pedro(More)
