Cystic fibrosis transmembrane conductance regulator (CFTR) acts as a cAMP-dependent chloride channel, has been studied in various types of cells. CFTR is abundantly expressed in vascular smooth muscle cells and closely linked to vascular tone regulation. However, the functional significance of CFTR in basilar vascular smooth muscle cells (BASMCs) remains elusive. Accumulating evidence has shown the...
Palmitate, a common saturated free fatty acid (FFA), has been demonstrated to induce preadipocyte apoptosis in the absence of adipogenic stimuli, suggesting that preadipocytes may be prone to apoptosis under adipogenic insufficient conditions, like type 2 diabetes mellitus (T2DM). ClC-3, encoding Cl− channel or Cl−/H+ antiporter, is critical for cell fate choices of proliferation versus apoptosis...
Endothelial progenitor cells (EPCs) play an important role in postnatal neovascularization and re-endothelialization in response to tissue ischemia and endothelial injury. It is reported that the circulating EPCs number is decreased during hypertension. However, the detailed mechanism is still unclear. Our previous studies have shown that ClC-3 chloride channel is up-regulated with the development...
Bestrophin 3 (Best-3) is expressed in a variety of tissues, such as cardiac, smooth muscle and renal tissues, and it is highly expressed in rat basilar arterial smooth muscle cells (BASMCs). Lee et al. (Biochim Biophys Acta 1823:1864–1876, 2012) reported that Best-3 prevented apoptotic cell death induced by endoplasmic reticulum stress. In the present study, we used small interference RNA (siRNA)...
Our previous studies showed that ginsenoside-Rd, a purified component from Panax notoginseng, inhibited cell proliferation and reversed basilar artery remodeling. The aim of this study was to investigate whether ginsenoside- Rd influences H2O2-induced apoptosis in basilar artery smooth muscle cells (BASMCs). The results showed that ginsenoside-Rd significantly potentiated H2O2-induced cell death and...
Vinpocetine is a clinically used drug for cerebrovascular disorders as well as age-related memory impairment. Of note, vinpocetine has been recently identified as a novel anti-inflammatory agent; however, its effects on cancer cells remain to be investigated. In the present study, we found that vinpocetine potently inhibited proliferation of multiple types of human breast cancer cells by arresting...
ClC-3 Cl− channel plays an important role in cell volume regulation and cell cycle. In vascular smooth muscle cells, we have found that ClC-3 was involved in ET-1 induced cell proliferation. The present study was designed to further investigate the role of ClC-3 Cl− channel in H2O2-induced apoptosis and its underlying mechanisms in rat basilar arterial smooth muscle cell (BASMCs). By using ClC-3 cDNA...
