WitrynaThe selective HERG channel blocker, E-4031, reduced proliferation of CEM, U937, and K562 cells, and this appears to be the first direct evidence of a functional role for the HERG current in cancer cells. Selective up-regulation of h-erg appears to occur in neoplastic hematopoietic cells, thus providing a marker and potential therapeutic target. WitrynaWT and D540K HERG channels were blocked by MK-499 in a concentration-dependent man- ner (Fig. 6). Concentration-response curves were con- structed by measuring steady state current amplitudes at ...

hERG (the human Ether-à-go-go-Related Gene) is a gene (KCNH2) that codes for a protein known as Kv11.1, the alpha subunit of a potassium ion channel. This ion channel (sometimes simply denoted as 'hERG') is best known for its contribution to the electrical activity of the heart: the hERG channel … Zobacz więcej hERG forms the major portion of one of the ion channel proteins (the 'rapid' delayed rectifier current (IKr)) that conducts potassium (K ) ions out of the muscle cells of the heart (cardiac myocytes), … Zobacz więcej A detailed atomic structure for hERG based on X-ray crystallography is not yet available, but structures have recently been solved by … Zobacz więcej This channel is also sensitive to drug binding, as well as decreased extracellular potassium levels, both of which can result in decreased … Zobacz więcej The hERG gene was first named and described in a paper by Jeff Warmke and Barry Ganetzky, then both at the University of Wisconsin–Madison. The hERG gene is the human homolog of the Ether-à-go-go gene found in the Drosophila fly; Ether-à-go-go was … Zobacz więcej Loss-of-function mutations in this channel may lead to long QT syndrome (LQT2), while gain-of-function mutations may lead to short QT syndrome. Both clinical disorders stem from ion channel dysfunction (so-called channelopathies) that can lead … Zobacz więcej Due to the documented potential of QT-interval-prolonging drugs, the United States Food and Drug Administration issued … Zobacz więcej HERG has been shown to interact with the 14-3-3 epsilon protein, encoded by YWHAE. Zobacz więcej WitrynaHuman ether-a-go-go-related gene (hERG) channel blockade by small molecules is a big concern during drug development in the pharmaceutical industry. Failure or inhibition of hERG channel activity caused by drug molecules can lead to prolonging QT interval, which will result in serious cardiotoxicity. eastenders 13 october 2022WitrynaAll the 15 IKr and/or hERG current inhibitors that have been reported (9 compounds) or not reported (6 compounds) to inhibit calcium currents prolonged APD 30–60 , APD 60–90 , and/or APD 30 ... eastenders 13 april 2022
