| 1 | Cadmium accumulation and tolerance of two castor cultivars in relation to antioxidant systems显示文摘To investigate the effects of Cd on tolerance and antioxidant activities of castor, two different castor(Ricinus communis L.) cultivars(Zibo No. 5 and Zibo No. 8) were used for a hydroponic experiment(0, 1 and 2 mg/L Cd) and a pot experiment using Cd-contaminated soil(34 mg/kg) with the addition of ethylenedinitrilotetraacetic acid(EDTA). The results indicated that there were significant differences between the two cultivars with respect to Cd uptake in shoots(113–248 mg/kg for Zibo No. 5 and 130–288 mg/kg Zibo No. 8), biomass tolerance indexes(64.9%–74.6% for Zibo No. 5 and 80.1%–90.9% for Zibo No. 8) in the hydroponic experiment and survival rates(0% for Zibo No. 5 and 100% for Zibo No. 8)determined by the addition of EDTA in the pot experiment, suggesting that Zibo No. 8 has higher tolerance than Zibo No. 5. Moreover, the castor cultivars have low bioconcentration factors(4.80% for Zibo No. 5 and 5.43% for Zibo No. 8) and low translocation factors(<1%).Consequently, Zibo No. 8 can participate in Cd phytostabilization in highly Cd-polluted areas. The results indicated that glutathione(GSH) as a non-enzymatic antioxidant, and antioxidant enzymes including superoxide dismutase(SOD), catalase(CAT) and guaiacol peroxidase(GPX), were cultivar- and dose-dependent. The higher tolerance of Zibo No. 8compared with Zibo No. 5 can be attributed to the higher GSH levels in the root and higher GPX activity in the leaf. | Hanzhi Zhang Qingjun Guo Junxing Yang Tongbin Chen Guangxu Zhu Marc Peters Rongfei Wei Liyan Tian Chunyu Wang Deyun Tan Jie Ma Gangming Wang Yingxin Wan | 2014 | Journal of Environmental Sciences2014，26，10： | 15 |

| 3 | Treatment of hepatitis C virus core-positive hepatocytes with the transfer of recombinant caspase-3 using the 2~,5^-oligoadenylate synthetase gene promoter显示文摘丙肝病毒(HCV ) 感染在全世界是肝相关的病态和死亡的一个领先的原因。没有可得到的疫苗,当前的治疗部分仅仅是有效的。因为 HCV 感染仅仅少数 hepatocytes,我们假设了 apoptosis 的那正式就职可能是为丙肝的处理的一条有希望的途径。在现在的学习,因为它有能力导致独立于开始者 caspases 的 apoptosis, recombinant caspase-3 基因(re-caspase-3 ) 被使用。一个 HCV 特定的倡导者被要求在感染 HCV 的房间调整细胞毒素的 caspase-3 表示。HCV 核心蛋白质罐头明确地激活 2,5-oligoadenylate 合成酶(美洲国家组织) ,这被报导了在人的 hepatocytes 的基因倡导者。因此,我们构造了在 OAS 基因倡导者(pGL3-OAS-re-caspase-3 ) 下面由 re-caspase-3 组成的表示向量然后在 HCV 核心积极的肝房间上调查了它的效果。pGL3-OAS-re-caspase-3 构造在 HCV 核心积极的肝房间,然而并非在正常的肝房间导致了 apoptosis,这被发现。这些结果强烈建议在 OAS 倡导者下面的 re-caspase-3 基因的转移是为 HCV 感染的处理的一条新奇指向途径。 | Ying Wang Shanshan Mao Bo Li Pingping Tan Deyun Feng Jifang Wen | 2009 | Acta Biochimica et Biophysica Sinica2009，41，7： | 1 |
