hERG (KV11.1) Background Information
KV11.1, better known as hERG (human Ether-à-go-go-Related Gene), contributes to the electrical activity of the heart that coordinates the heart's beating (i.e., the hERG channel mediates the repolarizing IKR current in the cardiac action potential). When this channel's ability to conduct electrical current across the cell membrane is inhibited or compromised, either by application of drugs or by rare mutations in some families, it can result in a potentially fatal disorder called long QT syndrome; a number of clinically successful drugs in the market have had the tendency to inhibit hERG, and create a concomitant risk of sudden death, as a side-effect, which has made hERG inhibition an important antitarget that must be avoided during drug development. Due to the documented potential of QT interval prolonging drugs, the United States Food and Drug Administration issued recommendations for the establishment of a cardiac safety profile during pre-clinical drug development: ICH S7B.
hERG has also been associated with modulating the functions of some cells of the nervous system and with establishing and maintaining cancer-like features in leukemic cells.

The image shows example traces for hERG mediated currents at 25 ± 2 °C (black) and 35 ± 2 °C (blue). The peak current amplitude was increased at 35 °C, and the rise time and decay time constants were faster at physiological temperature compared with those obtained at room temperature.
hERG - Stable Recordings with Accurate Pharmacology
SyncroPatch 384PE (a predecessor model of SyncroPatch 384i) data and applications:
Cells were kindly provided by Charles River Laboratories.
Current-voltage relationship of hERG (Kv11.1) expressed in HEK293 is shown along with pharmacology of 4 hERG-active compounds. The current-voltage relationships for all 384 wells (top) using perforated patch (Escin) and multi-hole chips (4 holes per well) are shown. In all 384 wells, a hERG-mediated current was observed with peak amplitude >700 pA at -20 mV. Using a pharmacology voltage protocol, experiments were stable lasting over 20 minutes. Concentration response curves for astemizole, pimozide, cisapride and terfenadine revealed IC50 values consistent with those found in the literature.

Voltage gated channels such as hERG (expressed in HEK293) have been used to validate the system. These traces show the raw current responses of a single cell to a hERG IV pulse protocol. The data were recorded on the SyncroPatch 96. In the upper screenshot raw current traces are shown. In the lower one the same current traces after leak subtraction are shown.
hERG - Stable Recordings
Patchliner data and applications:
Cells were kindly provided by Cytomyx/Millipore, UK.
A series of drug concentrations can be applied to each cell. The top figures show the original traces and the corresponding average dose-response curve. Five concentrations of Quinidine (0.1, 0.3, 1, 3 and 10 μM) have been applied.
The lower figure shows the corresponding Imax (-40 mV) including a wash out step and an additional application of the blocker to demonstrate the stability of whole cell recordings.
Cardiomyocytes - Time-dependent effect of Pentamidine on Cor.4U cardiomyocytes
CardioExcyte data and applications:
Cells were kindly provided by Axiogenesis.
Time-dependent effect of Pentamidine on Cor.4U cardiomyocytes. Pentamidine clinically causes acquired long QT syndrome, which is associated with prolonged QT intervals, tachycardias, and sudden cardiac arrest. Pentamidine delays terminal repolarization in human heart by acutely blocking cardiac inward rectifier currents. At the same time, it reduces surface expression of the cardiac potassium channel IKr/human ether à-go-go-related gene (hERG).
