LDL stimulates mitogen-activated protein kinase phosphatase-1 expression, independent of LDL receptors, in vascular smooth muscle cells.
Low density lipoprotein (LDL) is a well-established risk factor for atherosclerosis, stimulating vascular smooth muscle cell (SMC) differentiation and proliferation, but the signal transduction pathways between LDL stimulation and cell proliferation are poorly understood. Because mitogen-activated protein kinases (MAPKs) play a crucial role in mediating cell growth, we studied the effect of LDL...
متن کاملRegulation of mitogen-activated protein kinase phosphatase-1 in vascular smooth muscle cells.
Mitogen-activated protein (MAP) kinase cascades are major signaling systems by which cells transduce extracellular cues into intracellular responses. In general, MAP kinases are activated by phosphorylation on tyrosine and threonine residues and inactivated by dephosphorylation. Therefore, MAP kinase phosphatase-1 (MKP-1), a dual-specificity protein tyrosine phosphatase that exhibits catalytic ...
متن کاملAldosterone stimulates vascular smooth muscle cell proliferation via big mitogen-activated protein kinase 1 activation.
The nongenomic effects of aldosterone have been implicated in the pathogenesis of various cardiovascular diseases. Aldosterone-induced nongenomic effects are attributable in part to the activation of extracellular signal-regulated kinase 1/2 (ERK1/2), a classical mitogen-activated protein (MAP) kinase. Big MAP kinase 1 (BMK1), a newly identified MAP kinase, has been shown to be involved in cell...
متن کاملRegulation of mitogen-activated protein kinase by protein kinase C and mitogen-activated protein kinase phosphatase-1 in vascular smooth muscle.
Vascular smooth muscle contraction is primarily regulated by phosphorylation of myosin light chain. There are also modulatory pathways that control the final level of force development. We tested the hypothesis that protein kinase C (PKC) and mitogen-activated protein (MAP) kinase modulate vascular smooth muscle activity via effects on MAP kinase phosphatase-1 (MKP-1). Swine carotid arteries we...
متن کاملLDL receptor-related protein mediates uptake of aggregated LDL in human vascular smooth muscle cells.
Foam cell formation is a key event in the onset and progression of atherosclerotic lesions. We have previously reported that internalization of aggregated low density lipoproteins (agLDLs) by vascular smooth muscle cells (VSMCs) produces cholesteryl ester (CE) accumulation in these cells. The aim of this study was to analyze whether the low density lipoprotein receptor-related protein (LRP) med...
