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:Analysis of 96-hours-old-rice seedlings with promoted-growth induced by implantation with low-energy nitrogen ion beam. Ion-beam implantation can induce changes in 351 up-regulated transcripts and 470 down-regulated transcripts, including signaling proteins, kinases, plant hormones, transposable elements, transcription factors, non-coding protein RNAs, secondary metabolites, resistance proteins, peroxidase, chromatin modification and even miRNAs. Results provide insight into the molecular basis of biological effects of plants that implanted by ion beam. Three sample groups—the controls, the ion-beam implanted samples and vacuum-treated samples. Three replicates were included in each sample group. Radiation induced gene expression rice seedlings was measured at 96 hours after germination of the seeds.

Project description:Rice (Oryza staiva) is staple food for the human consumption and model plants for genetic and molecular studies. Only few studies have been conducted on ultraviolet-B (UV-B) stress on rice. UV-B stress effects different morphological and physiological changes in plants. However, underlying mechanisms governing these integrated responses are unknown. In this study, we conducted proteomic response of rice leaves to UV-B stress using two-dimensional gel electrophoresis and identified the selected proteins by mass spectrometry analysis. To identify changes in protein accumulation in response to UV-B stress, two cultivars, i.e., IR6 and REX were irradiated by artificial UV-B radiation. Four 4 levels of daily biologically effective UV-B radiation intensities, 0 (control), 5, 10, and 15 kJ m-2 d-1 were imposed. We conducted this experiment in Sunlit Soil-Plant-Atmosphere-Research (SPAR) chambers to mimic the natural environment.
