Pre-existing diabetes increases the risk of maternal and fetal complications during pregnancy, which may be due to underlying maternal vascular dysfunction and impaired blood supply to the uteroplacental unit. Endothelial dysfunction and reduced vascular smooth muscle responsiveness to nitric oxide (NO) are common vascular impairments in type 2 diabetes (T2D). We hypothesized that uterine arter...
Transient receptor potential canonical (TRPC) proteins constitute a family of seven (TRPC1-7) nonselective cation channels within the wider TRP superfamily. TRPC1, TRPC3, TRPC4, TRPC5 and TRPC6 channels are expressed in vascular smooth muscle cells from human vessels of all calibers and in smooth muscle from organs such as the uterus and the gastrointestinal tract. TRPC channels have recently e...
We have examined the effects of bile duct ligation on vascular and extravascular smooth muscle responsiveness to noradrenaline and tyramine using isolated rat hindlimb perfusion, and portal vein and vas deferens preparations. Bile duct ligation reduced the contractile responses to noradrenaline of vascular and extravascular smooth muscle. Exposure of smooth muscle to some bile salts caused a re...
Factors in plasma and platelets do not fully account for the proliferation of smooth muscle cells in vascular injury, implying that additional factors are involved. Recently, we and others have observed that vascular injury regulates basic fibroblast growth factor, suggesting a further role for this pleiotropic factor. We report here that injury of rat arteries leads to an increase in fibroblas...
OBJECTIVE The purpose of this study was to investigate whether the altered vascular resistance in pregnancy and preeclampsia results from alterations in intrinsic vascular smooth muscle properties or from external influences on vascular smooth muscle function. STUDY DESIGN We studied subcutaneous resistance arteries from women with preeclampsia, from normal pregnant women, and from nonpregnan...
OBJECTIVE Defective smooth muscle expression of LDL receptor-related protein-1 (Lrp1) increases atherosclerosis in hypercholesterolemic mice. This study explored the importance of smooth muscle Lrp1 expression under normolipidemic conditions. METHODS AND RESULTS Smooth muscle cells isolated from control (smLrp1(+/+)) and smooth muscle-specific Lrp1 knockout (smLrp1(-/-)) mice were characteriz...
The prostanoid thromboxane A2 has been implicated to contribute to the pathogenesis of many cardiovascular diseases, including hypertension. To study the role of vascular thromboxane-prostanoid (TP) receptors in blood pressure regulation, we generated mice with cell-specific deletion of TP receptors in smooth muscle using Cre/Loxp technology. We crossed the KISM22α-Cre transgenic mouse line exp...
Several studies during the last years have shown that, in addition to endothelial cells, vascular smooth muscle cells also express the cellular adhesion molecules ICAM-1 and VCAM-1 in atherosclerosis, restenosis and transplant vasculopathy. In vitro studies have characterized stimulatory and inhibitory factors that regulate the expression of ICAM-1 and VCAM-1 on cultured smooth muscle cells. Th...
The therapeutic effects of diltiazem hydrochloride are believed to be related to its ability to inhibit the cellular influx of calcium ions during membrane depolarization of cardiac and vascular smooth muscle. Mechanisms of Action Hypertension: Diltiazem produces its antihypertensive effect primarily by relaxation of vascular smooth muscle and the resultant decrease in peripheral vascular resis...
Oxidized low-density lipoprotein (oxLDL) is involved in the pathological phenotypic transformation of vascular smooth muscle cells in atherosclerosis. Galectin‑3 also has an important role in atherosclerosis. However, little is currently known regarding the effects of galectin‑3 on the oxLDL‑induced phenotypic transformation of vascular smooth muscle cells. In the present study, primary culture...
