Abnormal vascular smooth muscle (VSM) cell proliferation contributes to the development of atherosclerosis and its associated disorders, including angioplasty restenosis. The tumor-suppressor protein p53 has been linked to the development of atherosclerotic lesions, and its homolog, p73, is proving to have contrasting functions in a variety of tissues. As an outgrowth of our previous finding th...

Objective—Regulation of vascular smooth muscle (VSM) proliferation and contractile differentiation is an important factor in vascular development and subsequent cardiovascular diseases. Recently, microRNAs (miRNAs) have been shown to regulate fundamental cellular processes in a number of cell types, but the integrated role of miRNAs in VSM in blood vessels is unknown. Here, we investigated the ...

With the emergence of a business era that embraces changes as one of its major characteristics, manufacturing success and survival are becoming more and more difficult to ensure. The emphasis is on adaptability to changes in the business environment and on addressing market and customer needs proactively. Changes in the business environment due to varying needs of the customers lead to uncertai...

Several hypertensive states are associated with resistance to insulin-induced glucose disposal and insulin-induced vasodilation. Insulin can inhibit vascular smooth muscle (VSM) contraction at the level of the VSM cell, and resistance to insulin's inhibition of VSM cell contraction may be of pathophysiological importance. To understand the VSM cellular mechanisms by which insulin resistance lea...

Genetic variations of far-reaching consequences have been established between spontaneously hypertensive rats (SHR) and their controls, Wistar Kyoto rats (WKY). The SHR strain is the most widely used model for the study of genetic hypertension. Calcium homeostasis in the vascular smooth muscle (VSM) is controlled by calcium channels and calcium pumps located in both VSM and the overlying endoth...

VSM is a mature model of text representation for categorization. Words are commonly used as dimensions of feature space of VSM, but words only provide little semantic information. Sentence category theory is an important component of HNC theory and can provide abundant information about meaning, structure and style of a sentence. We use sentence categories as dimensions of feature space, reduce...

The multifunctional Ca(2+)/calmodulin-dependent protein kinase II δ-isoform (CaMKIIδ) promotes vascular smooth muscle (VSM) proliferation, migration, and injury-induced vascular wall neointima formation. The objective of this study was to test if microRNA-30 (miR-30) family members are endogenous regulators of CaMKIIδ expression following vascular injury and whether ectopic expression of miR-30...

Vascular damage signals smooth muscle cells to proliferate, often exacerbating existing pathologies. Although the role of changes in "global" Ca2+ in vascular smooth muscle (VSM) cell dedifferentiation has been studied, the role of specific Ca2+ signals in determining VSM phenotype remains relatively unexplored. Earlier work with cultured VSM cells suggests that inositol 1,4,5-trisphosphate rec...

Vascular smooth muscle (VSM) cell migration is a critical step in the development of a neointima after angioplasty. Matrix metalloproteinases (MMPs) degrade the basement membrane and extracellular matrix, facilitating VSM cell migration. Recently, we demonstrated that nitric oxide (NO) inhibits interleukin-1 beta (IL-1 beta)-stimulated MMP-9 induction in rat aortic VSM cells. In this study, we ...
