| Research Abstract |
In the present study, we tried to determine whether intratracheal administration of siRNA against green fluorescence protein (GFP) could inhibit gene expression of GFP in the lungs of GFP-transgenic mouse or in the lung tumor which was generated by the intrathoracic inoculation of Lewis lung adenocarcinoma (LLC) cells over-expressing GFP (GFP-LLC). To detect fluorescence from GFP in the lung, Biozero fluorescence microscope (Keyence, Osaka, Japan) was used. The strong fluorescence signals were observed both in the lung of GFP transgenic mice and in the lung tumor consisting of GFP-LLC cells. However, intratracheal administration of siRNA against GFP did not inhibit the degree of florescence signal. The amount of siRNA used in the study might be insufficient.
