Development of recombinant cell line co-expressing mutated Nav1.5, Kir2.1, and hERG for the safety assay of drug candidates.

To provide a high-throughput screening method for human ether-a-go-go-gene-related gene (hERG) K(+) channel inhibition, a new recombinant cell line, in which single action potential (AP)-induced cell death was produced by gene transfection. Mutated human cardiac Na(+) channel Nav1.5 (IFM/Q3), which shows extremely slow inactivation, and wild-type inward… CONTINUE READING
