Caveolar nanospaces in smooth muscle cells
Caveolae, specialized membrane nanodomains, have a key role in signaling processes, including calcium handling in smooth muscle cells (SMC). We explored the three-dimensional (3D) architecture of peripheral cytoplasmic space at the nanoscale level and the close spatial relationships between caveolae, sarcoplasmic reticulum (SR), and mitochondria, as ultrastructural basis for excitation-contract...
متن کاملROCK1 translocates from non-caveolar to caveolar regions upon KCl stimulation in airway smooth muscle.
Airway smooth muscle (ASM) membrane depolarization through KCl opens L-type voltage dependent Ca2+ channels (Ca(v)1.2); its opening was considered the cause of KCl contraction. This substance is used to bypass intracellular second messenger pathways. It is now clear that KCl also activates RhoA/Rho kinase (ROCK) pathway. ROCK isoforms are characterized as ROCK1 and ROCK2. Because ROCK1 seems th...
متن کاملThe Effect of Adiponectin on Matrix Metalloproteinase-9 (MMP-9) in Vascular Smooth Muscle Cells
Background & Aims: Atherosclerosis is a major cause of morbidity and mortality. Adiponectin reducesthe risk of heart disease, and matrix metalloproteinase-9 (MMP-9) is involved in the formation and development of atherosclerotic plaque. The aim of this study was the investigation of the effect of adiponectin on MMP-9 gene expression. It seems this hormone can reduce the risk of atherosclerosis ...
متن کاملChannels in Smooth Muscle Cells
The effects of sulfhydryl reduction/oxidation on the gating of large-conductance, Ca 2 1 -activated K 1 (maxi-K) channels were examined in excised patches from tracheal myocytes. Channel activity was modified by sulfhydryl redox agents applied to the cytosolic surface, but not the extracellular surface, of membrane patches. Sulfhydryl reducing agents dithiothreitol, b -mercaptoethanol, and GSH ...
متن کاملSmooth Muscle Cells
Vasoconstrictors such as arginine vasopressin (AVP) and angiotensin II (Ang II) have been shown to increase protein and mRNA levels of smooth muscle a-actin (SM-a-actin) in vascular smooth muscle cells. In the same cells, platelet-derived growth factor (PDGF) decreased SM-aactin protein and mRNA. The rat SM-a-actin promoter that has recently been isolated contains two E-boxes and three CC(A/T)6...
