Vascular smooth muscle cell differentiation-2010
Vascular smooth muscle cells have attracted considerable interest as a model for a flexible program of gene expression. This cell type arises throughout the embryo body plan via poorly understood signaling cascades that direct the expression of transcription factors and microRNAs which, in turn, orchestrate the activation of contractile genes collectively defining this cell lineage. The discove...
متن کاملAT2 receptor and vascular smooth muscle cell differentiation in vascular development.
The angiotensin II type 2 (AT2) receptor is transiently expressed at late gestation in the fetal vasculature, but its expression rapidly declines after birth. We have previously demonstrated that the expression of this receptor mediates decline in vascular DNA synthesis that occurs at this stage of vascular development. To examine further the role of the AT2 receptor in vasculogenesis, we have ...
متن کاملInflammation and Vascular Calcification Causing Effects of Oxidized HDL are Attenuated by Adiponectin in Human Vascular Smooth Muscle Cells
The role of oxidized high-density lipoprotein (oxHDL) and the protective effects of adiponectin in terms of vascular calcification is not well established. This study was conducted to investigate the effects of oxHDL with regards to inflammation and vascular calcification and to determine the protective role of adiponectin in attenuating the detrimental effects of oxHDL. Cell viability, mineral...
متن کاملSympathetic innervation promotes vascular smooth muscle differentiation.
The sympathetic nervous system (SNS) is an important modulator of vascular smooth muscle (VSM) growth and function. Several lines of evidence suggest that the SNS also promotes VSM differentiation. The present study tests this hypothesis. Expression of smooth muscle myosin (SM2) and alpha-actin were assessed by Western analysis as indexes of VSM differentiation. SM2 expression (normalized to al...
متن کاملRedox regulation of vascular smooth muscle cell differentiation.
Experiments were performed to determine the role of reactive oxygen species (ROS) in regulating vascular smooth muscle cell (VSMC) phenotype. After quiescence, cultured human VSMCs increased their expression of differentiation proteins (alpha-actin, calponin, and SM1 and SM2 myosin), but not beta-actin. ROS activity, determined using the H(2)O(2)-sensitive probe dichlorodihydrofluorescein (DCF)...
