| Outline of Final Research Achievements |
To estimate radiation induced mutation frequency with single-cell sequencing, HT1080 single cells were sorted and gamma-irradiated 0.4 Gy and 2 Gy. The cell divided several times, DNA was extracted from each single cell and we performed whole genome amplification (MALBAC method), exon capture and NGS sequence.
The number of 2 Gy specific base substitutions was 20 and indels were 3 in 7.5 Mbp. The number of 0.4 Gy specific base substitutions was 27 and indels were not detected in 14 Mbp.
