Novel genes for mitogen-independent smooth muscle replication.
Vascular smooth muscle cells (SMCs) are generally assumed to require mitogenic stimulation to replicate. The mitogen may originate in the circulation, be derived from nearby cell types in the vessel wall, or be produced by SMCs themselves. Regardless of the source of the mitogen, requirements for activation of cell surface growth factor receptors and consequent downstream signaling pathways hav...
متن کاملActivation of big mitogen-activated protein kinase-1 regulates smooth muscle cell replication.
This study examined the activation of big mitogen-activated protein (MAP) kinase-1 (BMK1) in rat carotid smooth muscle cells (SMCs). Platelet-derived growth factor, fibroblast growth factor-2, sorbitol, and serum all increased the activation of BMK1 in rat carotid SMCs, whereas angiotensin II, phorbol esters, and tumor necrosis factor-alpha had only slight effects. With the exception of tumor n...
متن کاملA Mitogen and Chemoattractant for Vascular Smooth Muscle Cells
Interleukin-8 (IL-8) is a chemokine produced by a variety of cell types involved in atherogenesis and is chemotactic for neutrophils and lymphocytes. A recent study has shown that IL-8 is angiogenic and induces proliferation and chemotaxis of endothelial cells. The present study was undertaken to find out whether IL-8 is also mitogenic and chemotactic for vascular smooth muscle cells. IL-8 indu...
متن کاملAngiotensin II induces vascular smooth muscle cell replication independent of blood pressure.
The purpose of this investigation was to evaluate the role of blood pressure in the proliferative response of vascular smooth muscle cells to systemic infusion of angiotensin II (Ang II). Our laboratory has previously shown that infusion of Ang II induces smooth muscle cell proliferation in rat mesenteric vessels and carotid arteries. Ang II, a strong vasopressor, raised systolic blood pressure...
متن کاملInterferons modulate mitogen-induced protein synthesis in airway smooth muscle.
Severe asthma is characterized by increased airway smooth muscle (ASM) mass due, in part, to ASM cell growth and contractile protein expression associated with increased protein synthesis. Little is known regarding the combined effects of mitogens and interferons on ASM cytosolic protein synthesis. We demonstrate that human ASM mitogens including PDGF, EGF, and thrombin stimulate protein synthe...
