| Research Abstract |
This study aimed to construct the basis for genetic code expansion in silkworm, Bombyx mori. NMD, nonsense-mediated mRNA decay, could be an obstacle for genetic code expansion using stop codon reassignment methodology. In this study, it was investigated that mRNAs intrinsically degraded by NMD could be stabilized by knocking NMD-related genes out in silkworm cultured cells. We transfected TALE nucleases which target NMD-related genes to the cultured cells. Changes in the targeted gene sequences and in the expression of a fluorescent protein whose mRNA is sensitive to NMD were investigated after the transfection. We detected some changes in the targeted gene sequences but no apparent changes in the expression of the fluorescent protein were observed.
