Vascular smooth muscle cell motility: From migration to invasion.
- Sherif F Louis, P. Zahradka
- BiologyExperimental and Clinical Cardiology
The characteristics of vascular smooth muscle cell phenotypes as they relate to cell migration are discussed based on insights from recent molecular findings and a central theme is the mechanisms involved in nonpathogenic VSMC migration during tissue repair versus VSMC invasion that leads to the development of vascular diseases.
Variations in Adipokine Genes AdipoQ, Lep, and LepR are Associated with Risk for Obesity-Related Metabolic Disease: The Modulatory Role of Gene-Nutrient Interactions

The findings of single nucleotide polymorphisms in these three genes and their effect on obesity and metabolic disease risk are summarized and studies of gene-nutrient interactions involving adiponectin, leptin, and the leptin receptor are highlighted to emphasize the critical role of diet in susceptible populations.

Data indicate that PI3K may operate as a mediator of vascular SMC growth after stimulation with Ang II, and a potential correlation between angiotensin-mediatedPI3K activation and SMCrowth was found using LY294002, a specific inhibitor of PI3k.

Data indicate that sarpogrelate operates as a specific inhibitor of 5-HT-mediated cell proliferation and is a good candidate for preventing serotonin-induced neointimal hyperplasia.
Transactivation of the insulin-like growth factor-I receptor by angiotensin II mediates downstream signaling from the angiotensin II type 1 receptor to phosphatidylinositol 3-kinase.

Transactivation of the IGF-I receptor is a critical mediator of PI3-kinase activation by AngII but is not required for stimulation of the MAPK cascade, which argues that a paracrine/autocrine loop is not needed.
