Project description:To examine whether the local carbon ion radiotherapy affects the characteristics of the metastatic tumors, the expression profiles of the primary tumors and the lung metastases were studied in a mouse squamous cell carcinoma model by applying local radiotherapy with no irradiation (negative control), gamma-ray irradiation (reference beam), and carbon-ion irradiation. Keywords: mouse, squamous cell carcinoma, primary tumor, lung metastases, radiotherapy, carbon ion, gamma ray

Project description:To examine whether the local carbon ion radiotherapy affects the characteristics of the metastatic tumors, the expression profiles of the primary tumors and the lung metastases were studied in a mouse squamous cell carcinoma model by applying local radiotherapy with no irradiation (negative control), gamma-ray irradiation (reference beam), and carbon-ion irradiation. Keywords: mouse, squamous cell carcinoma, primary tumor, lung metastases, radiotherapy, carbon ion, gamma ray A highly metastatic mouse squamous cell carcinoma NR-S1 was implanted into the hind leg of synergetic C3H/HeNrs mice and irradiated with 5 Gy of carbon ion beam. 8 Gy of gamma ray was used as a reference beam. At 2 weeks after the irradiation, the lung tissue was sampled. In order to collect samples of primary tumors, the tumors were implanted in other mice and irradiated in the same manner, and the primary tumors were collected at 1 week after the irradiation. The tumor cells of the primary and metastatic tumors were collected by laser microdissection, and oligonucleotide microarray analysis of the irradiated primary tumors and the metastatic tumors were all performed in comparison to the non-irradiated primary tumor by two-color methods.

Project description:Here, male and female B6C3F1 mice were given single or fractionated whole-body exposure(s) to a monoenergetic carbon ion radiotherapy beam at the Heavy Ion Medical Accelerator in Chiba, Japan, matching the radiation quality delivered to the normal tissue ahead of the tumour volume. These mice were then monitored for the remainder of their lifespan and a large number of T cell lymphomas were analysed, alongside those arising in mice exposed to equivalent doses of standard Cs137 gamma ray-irradiation. Using genome-wide DNA copy number analysis to identify genomic loci involved in radiation-induced lymphomagenesis and subsequent detailed analysis of Notch1, Ikaros, Pten, Trp53 and Bcl11b genes we compared the genetic profile of the carbon ion- and gamma ray-induced tumours. The canonical set of genes previously associated with radiation-induced T cell lymphoma was identified in both radiation groups. While the pattern of disruption of the various pathways was somewhat different between the radiation types, most notably Pten mutation frequency and loss of heterozygosity flanking Bcl11b, the most striking finding was the observation of large interstitial deletions at various sites across the genome in carbon ion-induced tumours, which were only seen infrequently in the gamma ray-induced tumours analysed. 32 unique tumours (12 gamma ray-induced, 20 carbon ion-induced) each with sex-matched reference DNA

Project description:This study uses microarray analysis to examine the fate of multiple C-ion-irradiated tumors in vivo to gain a comprehensive overview of the changes in gene expression induced by C-ion irradiation. Four murine tumors were irradiated in vivo with C-ions at a single dose, and gamma-rays were used as a reference beam. Keywords: mouse squamous cell carcinoma and fibrosarcoma, carbon ion-irradiation, gamma-irradiation, resected sample, transplanted tissues

Project description:Gene expression profiling was used to identify genes that display radiation-induced transcriptional change over tumor histopathology. Keywords: mouse squamous cell carcinoma, fibrosarcoma and mammary carcinoma, gamma-irradiation, carbon ion irradiation, resected sample, transplanted tissues C3H/HeMs male mice were irradiated by gamma-rays (30Gy, 50Gy, 70Gy) or carbon ions (30Gy) as local irradiation in single doses to hind legs where each tumor was transplanted. Animals were sacrificed either before irradiation (pre) or 1 day after irradiation (day 1) for expression analysis.
