Mineralocorticoid receptor activation promotes vascular cell calcification.
OBJECTIVE Clinical studies demonstrate that mineralocorticoid receptor (MR) antagonism improves outcomes in cardiovascular patients and that vascular calcification correlates with adverse cardiac events. We have recently demonstrated that human vascular smooth muscle cells (VSMCs) express functional MRs that, in response to aldosterone, modulate expression of osteogenic genes including alkaline...
متن کاملInhibition of FOXO1/3 promotes vascular calcification.
OBJECTIVE Vascular calcification is a characteristic feature of atherosclerosis, diabetes mellitus, and end-stage renal disease. We have demonstrated that activation of protein kinase B (AKT) upregulates runt-related transcription factor 2 (Runx2), a key osteogenic transcription factor that is crucial for calcification of vascular smooth muscle cells (VSMC). Using mice with SMC-specific deletio...
متن کاملCaspase-dependent and -independent activation of acid sphingomyelinase signaling.
Recent evidence suggests clustering of plasma membrane rafts into ceramide-enriched platforms serves as a transmembrane signaling mechanism for a subset of cell surface receptors and environmental stresses (Grassme, H., Jekle, A., Riehle, A., Schwarz, H., Berger, J., Sandhoff, K., Kolesnick, R., and Gulbins, E. (2001) J. Biol. Chem. 276, 20589-20596; Cremesti, A., Paris, F., Grassme, H., Holler...
متن کاملVitamin K-dependent proteins, warfarin, and vascular calcification.
Vitamin K-dependent proteins (VKDPs) require carboxylation to become biologically active. Although the coagulant factors are the most well-known VKDPs, there are many others with important physiologic roles. Matrix Gla Protein (MGP) and Growth Arrest Specific Gene 6 (Gas-6) are two particularly important VKDPs, and their roles in vascular biology are just beginning to be understood. Both functi...
متن کاملVascular calcification is dependent on plasma levels of pyrophosphate
Plasma levels of pyrophosphate, an endogenous inhibitor of vascular calcification, are reduced in end-stage renal disease and correlate inversely with arterial calcification. However, it is not known whether the low plasma levels are directly pathogenic or are merely a marker of reduced tissue levels. This was tested in an animal model in which aortas were transplanted between normal mice and E...
