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 rectifier K+ channel, Kir2.1, were stably co-expressed in HEK293 cells (IFM/Q3+Kir2.1). In IFM/Q3+Kir2.1, application of single electrical stimulation (ES) elicited a long AP lasting more than 30 s and led cells to die by more than 70%, whereas HEK293 co-transfected with wild-type Nav1.5 and Kir2.1 fully survived. The additional expression of hERG K+ channels in IFM/Q3+Kir2.1 shortened the duration of evoked AP and thereby markedly reduced the cell death. The treatment of the cells with hERG channel inhibitors such as nifekalant, E-4031, cisapride, terfenadine, and verapamil, recovered the prolonged AP and dose-dependently facilitated cell death upon ES. The EC50 values to induce the cell death were 3 µM, 19 nM, 17 nM, 74 nM, and 3 µM, respectively, whereas 10 µM nifedipine did not induce cell death. Results indicate the high utility of this cell system for hERG K+ channel safety assay.

A recombinant cell line (SOgE) was established, which was derived from the permanent quail muscle cell line QM7 and constitutively expressed the glycoprotein E (gE) gene of Marek′s disease virus serotype 1 (MDV-1). The SOgE cell line supported growth of virulent (RB-1B) and vaccine (CVI988, 584Ap80C) MDV-1 strains at a level comparable with that of primary chicken embryo cells (CEC). The SOgE cell line was used to produce a vaccine against Marek′s disease. Chickens were immunized at 1 day old with 103 p.f.u. CVI988 produced on either CEC or SOgE cells. Challenge infection was performed at day 12 with hypervirulent Italian MDV-1 strain EU1. Whereas 7/7 or 6/6 animals, respectively, immunized with SOgE or QM7 cells alone developed Marek′s disease, only 1/8 animals from both CVI988-immunized groups exhibited signs of disease, suggesting that SOgE cells are a valuable permanent cell culture system for MDV-1 vaccine production.
