Both TWIST and the endothelin-1 (ET-1)/endothelin A receptor (ETAR) signaling are important in osteosarcoma (OS) progression. In the present study, the interaction between TWIST and ET-1/ETAR signaling in OS cells was investigated, and the impact of the functional interaction on OS cell survival against chemotherapy agent-induced apoptosis was assessed. TWIST was overexpressed and knocked down ...
In humans, pruritus (itch) is a common but poorly understood symptom in numerous skin and systemic diseases. Endothelin 1 (ET-1) evokes histamine-independent pruritus in mammals through activation of its cognate G protein-coupled receptor endothelin A receptor (ETAR). Here, we have identified neural endothelin-converting enzyme 1 (ECE-1) as a key regulator of ET-1-induced pruritus and neural si...
This paper presents new equipment to investigate workers’ time activity patterns (TAP) in workenvironment. A real-time chemical sensor coupled with a data logger comprises the newelectronic time activity recorder (ETAR). TAP data obtained from traditional workers’ recalledquestionnaires, working schedule of the plant, and ETAR were compared with the goldenreference, direct obser...
Astrocyte elevated gene-1 (AEG-1) and endothelin-1 (ET-1)/endothelin A receptor (ETAR) signaling have been demonstrated to be important in osteosarcoma (OS) progression. In the present study, we explored the interaction between AEG-1 and ET-1/ETAR signaling in OS cells, and investigated the mechanism(s) through which the functional interaction may impact OS cell invasion and chemoresistance. Ov...
Post-cardiac arrest myocardial dysfunction is a major cause of mortality in patients receiving successful cardiopulmonary resuscitation (CPR). Mild therapeutic hypothermia (MTH) is the recommended treatment after resuscitation from cardiac arrest (CA) and is known to exert neuroprotective effects and improve short-term survival. Yet its cytoprotective mechanisms are not fully understood. In thi...
Two types of G protein-coupled receptors for endothelin-1 (ET-1), ET type A receptor (ETAR) and ETBR, closely resemble each other, but upon ET-1 stimulation, they follow totally different intracellular trafficking pathways; ETAR is recycled back to plasma membrane, whereas ETBR is targeted to lysosome for degradation. However, the mechanisms for such different fates are unknown. Here we demonst...
We review the role of endothelin (ET) A-receptors (R) on the coronary circulation. ET-1 maintains the normal coronary artery tone. ET-1 plasma levels are increased during and after coronary angioplasty and this increase is related to myocardial ischaemia rather than to mechanical artery injury. ETAR antagonists inhibit coronary artery vasoconstriction induced by ET release after coronary angiop...
The high mortality of epithelial ovarian cancer (EOC) is mainly caused by resistance to the available therapies. In EOC, the endothelin-1 (ET-1, EDN1)-endothelin A receptor (ETAR, EDNRA) signaling axis regulates the epithelial-mesenchymal transition (EMT) and a chemoresistant phenotype. However, there is a paucity of knowledge about how ET-1 mediates drug resistance. Here, we define a novel byp...
Cardiovascular diseases (CVDs) like hypertension are a major cause for death worldwide. In the cardiovascular tissue, endothelin system—consisting of receptor subtypes A (ETAR) and B (ETBR) mixed agonist 1 (ET-1)—is key player in regulation vascular tone blood pressure. Tight control this system is required to maintain homeostasis; otherwise, can severe CVDs pulmonary artery hypertension. The h...
Endothelin-1 and its receptors ETAR and ETBR, commonly referred to as the Endothelin-axis, are emerging to play a role in cancer. The Endothelin-axis has been shown to be involved in proliferation, angiogenesis and metastasis in various human tumours. To assess the role of the Endothelin-axis in renal cell carcinoma, we analysed its expression in archival tumour tissue of 183 patients. Represen...
