  51. Regulation of homologous recombinational repair by nuclear structure-associated proteins, Satoshi Tashiro, Satoshi Tashiro, Tsuyoshi Ikura, Jiying Sun, 74th Annual Meeting of the Japanese Cancer Association, 2015/10/10, Without Invitation, English, Nagoya Congress Center, DNA double-strand breaks (DSBs) are the major lethal lesion induced by ionizing radiation (IR). RAD51-dependent homologous recombination (HR) is one of the most important pathways in DSB repair and genome integrity maintenance. To understand the mechanism of RAD51-dependent HR, we searched for interacting partners of RAD51 by a proteomics analysis and identified lamin B1 in human cells. Lamins are nuclear lamina proteins that play important roles in the structural organization of the nucleus and the regulation of chromosome functions. Lamin B1 depletion repressed the DNA damage-dependent increase of RAD51 after IR. The repression was abolished by the proteasome inhibitor MG132, suggesting that lamin B1 stabilizes RAD51 by preventing proteasome-mediated degradation in cells with IR-induced DNA damage. We also showed that lamin B1 depletion repressed RAD51 focus formation and decreased the survival rates after IR. Based on these results, we propose that lamin B1 promotes DSB repair and cell survival by maintaining the RAD51 protein levels for HR, upon DSB induction after IR.

  53. Regulation of DNA Repair and Nuclear Lamina, Satoshi Tashiro, International Symposium on Chromatin Structure, Dynamics, and Function, 2015/08/25, Without Invitation, English, Awaji Yumebutai International Conference Center Awaji, Among the various types of DNA damage induced by ionizing radiation (IR), double strand breaks (DSBs) are regarded as the most serious impairment leading to cell death. In mammalian cells, DSBs are repaired mainly by one of two genetically distinct processes, non-homologous end joining (NHEJ) and homologous recombination (HR). RAD51, a recA homolog that forms helical filaments, binds to single-strand DNA, thus promoting recombinational repair. RAD51-dependent HR is one of the most important pathways in DSB repair and genome integrity maintenance. However, the mechanism of HR regulation by RAD51 remains unclear. To understand the mechanism of RAD51-dependent HR, we searched for interacting partners of RAD51 by a proteomics analysis and identified lamin B1 in human cells. Lamins are nuclear lamina proteins that play important roles in the structural organization of the nucleus and the regulation of chromosome functions. Immunoblotting analyses revealed that siRNA-mediated lamin B1 depletion repressed the DNA damage-dependent increase of RAD51 after IR. The repression was abolished by the proteasome inhibitor MG132, suggesting that lamin B1 stabilizes RAD51 by preventing proteasome-mediated degradation in cells with IR-induced DNA damage. We also showed that lamin B1 depletion repressed RAD51 focus formation and decreased the survival rates after IR. Based on these results, we propose that lamin B1 promotes DSB repair and cell survival by maintaining the RAD51 protein levels for HR, upon DSB induction after IR.
  54. Biological estimation of the DNA damage induced by CT scan, Satoshi Tashiro, The 15th International Congress of Radiation Research, 2015/06/27, With Invitation, English, Kyoto, Ionizing radiation can induce DNA damage. Human beings live under the environment with various types of DNA damaging agents, such as natural ionizing radiation and chemical agents. Therefore, human cells have DNA repair system to protect the genetic information from DNA damage. However, once cells received too much DNA damage to repair, apoptosis and/or changes of genetic information are induced. Accumulation of changes in genetic information has been shown to lead to carcinogenesis. Recent advance in medical image analysis, such as the development of high-speed multidetector CT, introduces the drastic progress in the field of diagnostic radiology. These progresses in diagnostic radiology strongly contribute to the progress in almost all fields of medicine. On the other hand, the health effect of medical exposure, especially CT scan, is still unclear. We have established a method to detect radiation-induced chromosome abnormalities, dicentric and ring chromosomes, by applying a fluorescence in situ hybridization (FISH) technique using telomere and centromere peptide nucleic acid (PNA) probes. We also examined the usefulness of immunofluorescence staining analysis using antibodies against DNA repair proteins in the estimation of DNA damage induced by CT scan. The possibility of the application of these techniques in the estimation of health effect of medical exposure will be discussed.
  55. Nuclear topography of homologous recombinational repair, Satoshi Tashiro, The 15th International Congress of Radiation Research, 2015/05/28, With Invitation, English, Kyoto University Research Reactor Institute, Kyoto, The chromosome territory-interchromatin compartment (CT-IC) model argues that nuclei are built up from two principal components, chromosome territories and the interchromatin compartment (IC). Several line of evidence suggests that the periphery of a chromatin domain bordering the IC represents the major nuclear sub-compartment for transcription, or co-transcriptional RNA splicing and DNA replication. However, the association of DNA metabolism, including DNA repair, with the higher order nuclear architectures are largely unknown. Homologous recombination repair (HR) is one of the major repair pathways of DNA double-strand breaks (DSBs) produced by endogenous and exogenous factors. A fraction of proteins involved in the HR pathway have been shown to accumulate at sites containing DNA damage to form damage induced nuclear foci. On the other hand, damaged chromatin is shown to be mobile after induction of DNA damage in a manner dependent on HR factors. However, the biological significance of such dynamic rearrangements of higher order nuclear architectures in HR is still unclear. Recent development of super-resolution microscopy has been expected to contribute the further understanding of the association of DNA metabolisms, such as HR, with higher order nuclear structures. RAD51 is a key factor in the HR pathway loaded on single stranded DNA processed around DSBs. In our previous study, we showed that RAD51 forms nuclear foci in S phase and at sites containing DNA damages. Recently, we found that the overexpressed RAD51 is accumulated within bundle-like sub-compartments of IC in human cell nucleus. Single stranded DNA formed at sites containing DNA damage for HR was detected within the sub-compartments. These findings support the notion that damaged chromatins are moved into the bundle-like sub-compartment of IC for HR, or HR factory. The usefulness of the super resolution microscopy in these analyses will be discussed.
