| Description
| - The interferon (IFN) response, induced as a side effect after transfection of nucleic acids into mammalian cells, is known but inadequately described. We followed the IFN response, the fate of cells, and the possible mechanisms leading to this response in NIH3T3 mouse fibroblasts after DNA nucleofection. The gateway destination vector, phGf, and its derivatives encoding toxic and non-toxic variants of the minor structural proteins of polyoma-viruses, VP2 and VP3, were used. DNA vector sequences induced in cells the production of high levels of IFN and the upregulation of the IFN-inducible genes, Mx-1, STAT1, IRF1, and IRF7. The IFN response was not restricted to phGf-derived plasmids. In nucleofected cells, upregulation of the modified gamma-histone 2A.X indicating DNA damage and inhibition of cell proliferation were also observed. Although 3T3 cells expressed the Toll-like receptor-9 (TLR9) and vectors used for nucleofection contained unmethylated CpGs, signaling leading to IFN induction was found to be TLR9 independent. However, the early activation of nuclear factor-kappa B suggested the participation of this transcription factor in IFN induction. Surprisingly, in contrast to nucleofection, transfection using a cationic polymer induced only a poor IFN response. Together, the results point to a strong side effect of nucleofection.
