| Outline of Final Research Achievements |
[Gene expression analysis using circulating tumor cells (CTCs)] We extracted RNA from the peripheral blood mononuclear cell fraction of 12 small-cell lung cancer patients and analyzed it for CTC-derived gene expression by the reverse transcriptase-polymerase chain reaction (RT-PCR). We investigated neuroendocrine-related, epithelial-mesenchymal-transition-related, and angiogenesis-related gene expression and were able to identify epithelial-mesenchymal transition-related gene expression. The results suggested that it is possible to identify CTC-related gene expression by this method.
[Gene mutation analysis using blood DNA] We analyzed tumor tissue derived DNA and blood DNA from 4 autopsy cases of advanced lung cancer by using a next generation sequencer. The same gene mutations as in the blood DNA were present in multiple lesions, and allele frequency in the tumor tissue was significantly higher.
