BACKGROUND: Hypertension and chronic renal failure (CRF) are considered models of accelerated arterial stiffening. Arterial stiffness increases further when CRF is associated with hypertension. We hypothesized that, in patients with mild CRF, aortic gene expression profile would include genes involved in arterial calcifications and enlargement....

OBJECTIVE: To evaluate modifications of arterial structure, gene expression, and function in our model of rats exposed to maternal diabetes. RESEARCH DESIGN AND METHODS: Morphometric analyses of elastic vessels structure and determination of thoracic aortic gene expression profile with oligonucleotide chips (Agilent, G4130, 22k) were performed...

Cell therapy holds promise for tissue regeneration, including in individuals with advanced heart failure. However, treatment of heart disease with bone marrow cells and skeletal muscle progenitors has had only marginal positive benefits in clinical trials, perhaps because adult stem cells have limited plasticity. The identification, among human...

The triggering receptor expressed on myeloid cells 1 (TREM-1) drives inflammatory responses in several cardiovascular diseases but its role in abdominal aortic aneurysm (AAA) remains unknown. Our objective was to explore the role of TREM-1 in a mouse model of angiotensin II-induced (AngII-induced) AAA. TREM-1 expression was detected in mouse...
