While nucleotide sequences 1 to 190 and 1 to 342 showed strong activity in three out of three lung cancer cell lines, nucleotide sequence 1 to 103 showed limited activity in H358, cells which show characteristics of type 2 alveolar cells. In vivo, the transcription initiation activities of nucleotide sequence 1 to 103 in the liver and the lung were minimal, while nucleotide sequences 1 to 190 and 1 to 342 showed strong activity comparable to that of the cytomegalovirus promoter. Further understanding of the transcription initiation activity of the left-end sequence of the adenovirus genome should lead to optimization of adenovirus vectors.
