Importance of the Choice of a Recombinant System to Produce Large Amounts of Functional Membrane Protein hERG.

Human ether-a-gogo related gene (hERG) product is the membrane potassium channel Kv11.1, which is involved in the electrical activity of the heart. As such, it is a key player in the toxicity of many drug candidates.

Fluorescent analogues of BeKm-1 with high and specific activity against the hERG channel.

Peptidic toxins that target specifically mammalian channels and receptors can be found in the venom of animals. These toxins are rarely used directly as tools for biochemical experiments, and need to be modified via the attachment of chemical groups (e.g.

Performance of comet and micronucleus assays in metabolic competent HepaRG cells to predict in vivo genotoxicity.

Genetic toxicity information is critical for the safety assessment of all xenobiotics. In the absence of carcinogenicity data, genetic toxicity studies may be used to draw conclusions about the carcinogenicity potential of chemicals. However, current in vitro assays have many limitations as they produce a high rate of irrelevant positive data and possible false negative data due to the weakness of the in vitro models used.
