| 内容記述 | T cell lymphomas in mice can overcome natural tumour barriers via several routes, including deregulation of Bcl11b, Notch, Pten or Ikaros via gene mutation, amplification or loss. Our research has shown that the etiology of T cell lymphomas (e.g. radiation or chemical mutagenesis) is correlated with a pattern in the disruption of the above pathways and how they are activated or inactivated. Carbon ion radiotherapy may be associated with different risks of secondary cancer than conventional photon therapies. A sub-cohort of mice irradiated with 4 or 4.8 Gy carbon ions starting at one week of age (either in a single exposure, or four weekly fractions), was selected for detailed genetic analysis of radiation-induced thymic lymphomas (n = 102 mice). Gross genomic changes at tumour suppressor loci including Pten, Bcl11b and Ikzf1 are being assessed by loss of heterozygosity (LOH) analysis and array-based comparative genome hybridisation. Smaller genetic alterations are being further assessed by exon sequencing of Pten, Bcl11b and Ikzf1 to identify small insertions/deletions and point-mutations. Preliminary results show that although the same pathways are involved in both carbon- and photon radiation-induced tumours, how these pathways are disrupted may be different between radiation types. Mechanistic insight into carbon ion-induced carcinogenesis will be vital in assessing the long-term safety of carbon ion radiotherapy for children. | |||||
