    最近我們實驗室在耐輻射球菌電離輻射敏感株中鑒定了一個與電離輻射抗性相關的基因ppri ，該基因可能通過調控dr細菌reca 、 ppra等基因的表達加速對電離輻射引起的dna損傷修復，而在大腸桿菌中表達ppri基因能促進reca 、 soda等表達水平顯著提高，使其抗輻射和抗氧化能力明顯增強，這將為我們理解其特殊抗性機制，特別是雙鏈斷裂修復提供新的線索。
  4. This research has closed relationship with a wide range of cross - science areas, such as basic research on cancer therapy by heavy ion radiation method, radiation danger level evaluation in space and biological damage induced by long term, low - level dose radiation environment, etc. dna is the carrier of biological information and the main target of biological effects induced by ionizing radiations

    從重離子治癌的基礎性和先導性的研究，載人航天飛行過程中的太空輻射危險性評估，到長期在低劑量輻照環境下的放射性對機體損傷等等，都與電離輻射所致生物損傷的研究有著密切的關系。 dna （脫氧核糖核酸）是生命信息的載體，也是輻射生物效應的最主要的靶分子。

    近年來，生物化學、細胞生物學以及分子生物學研究不斷地揭示了內皮細胞新的生理功能，本實驗對血管內皮細胞功能及其調節機制進行了一些的研究，期望揭示內皮細胞在血管新生及電離輻射損傷中的新機制。
  6. Rapid responses occured when cells were exposed to genotoxic stresses : one is initiating dna damage checkpoint that leads to arrest in gl, in order to provide the cell with sufficient time to repair damaged dna, or leads to arrest in g2, in order to avoid defective chromosome happening mitosis. on the other hand, if damage to the genome is excessive, the cells initiating apoptosis, when damages cannot be repaired

    這是因為細胞在受到諸如電離輻射等基因毒應激損傷時，細胞最先作出的細胞學反應：一，起始dnadamagecheckpoint使細胞周期阻滯（ arrest ）在g1期，贏得時間識別與修復損傷，避免損傷的dna進行錯誤的復制，或和阻滯在g2期，避免缺陷的染色體進一步分裂；二，損傷嚴重而修復無望啟動細胞死亡程序，清除那些帶有病變傾向的細胞危害機體。
