Probucol (PB) is a drug commonly used for the treatment of hyperlipidemia and atherosclerosis. In our previous study, we have proved that PB can ameliorate abdominal aortic aneurysm (AAA) induced by elastase in mice through its anti-inflammatory and anti-oxidative effect. In this study, the water solubility and oral absorption of PB were improved by encapsulating PB into nanostructured lipid ca...

B-lineage-committed cells are believed to arise in the liver of mouse embryos at 14 days after coitus (dpc). However, pre-B-specific gene transcripts and DJH gene rearrangements have been detected in earlier, midgestation embryos. We describe here a population of c-kit(+)AA4.1(+)CD19(+)Pax5(+) cells present in the aorta-gonad-mesonephros (AGM) area and in the livers of 11-dpc mouse embryos. In ...

The precise time of appearance of the first hematopoietic stem cell activity in the developing mouse embryo is unknown. Recently the aorta-gonad-mesonephros region of the developing mouse embryo has been shown to possess hematopoietic colony-forming activity (CFU-S) in irradiated recipient mice. To determine whether the mouse embryo possesses definitive hematopoietic stem cell activity in the a...

OBJECTIVE Identification of arterial genes and pathways altered in obesity and diabetes. RESEARCH DESIGN AND METHODS Aortic gene expression profiles of obese and diabetic db/db, high-fat diet-fed C57BL/6J, and control mice were obtained using mouse Affymetrix arrays. Neuronatin (Nnat) was selected for further analysis. To determine the function of Nnat, a recombinant adenovirus (Ad-Nnat) was ...

Changes in membrane tension resulting from membrane stretch represent one of the key elements in blood flow regulation in vascular smooth muscle. However, the molecular mechanisms involved in the regulation of membrane stretch remain unclear. In this study, we provide evidence that a vanilloid receptor (TRPV) homologue, TRPV2 is expressed in vascular smooth muscle cells, and demonstrate that it...

Objective: Gestational diabetes mellitus occurs during pregnancy is associated with increased cardiovascular risk. Carotid intima media thickness (CIMT) is a surrogate maker of subclinical atherosclerosis. The aim of this study is assessment of relationship between CIMT and infra-renal abdominal aorta diameter in women with and without Gestational Diabetes Mellitus. Materials and Methods: Th...

Plasminogen activator (PA) and PA inhibitor (PAI) antigen, activity, and mRNA were analyzed in the three layers of rat aorta, and the effect of endotoxin on PA and PAI was studied. All PA activity in aorta was identified as tissue-type PA (TPA) activity; no urokinase-type PA was detected. In the tunica adventitia TPA activity, TPA antigen, and TPA mRNA were detected, whereas in the tunica media...

Coronary arteries (CAs) stem from the aorta at 2 highly stereotyped locations, deviations from which can cause myocardial ischemia and death. CA stems form during embryogenesis when peritruncal blood vessels encircle the cardiac outflow tract and invade the aorta, but the underlying patterning mechanisms are poorly understood. Here, using murine models, we demonstrated that VEGF-C-deficient hea...
