| 1 | Seasonal variation effects on the formation of trihalomethane during chlorination of water from Yangtze River and associated cancer risk assessment显示文摘For the system of water samples collected from Yangtze River,the effects of seasonal variation and Fe(III) concentrations on the formation and distribution of trihalomethanes (THMs) during chlorination have been investigated.The corresponding lifetime cancer risk of the formed THMs to human beings was estimated using the parameters and procedure issued by the US EPA.The results indicated that the average concentration of THMs (100.81 μg/L) in spring was significantly higher than that in other seasons,which was related to the higher bromide ion concentration resulted from the intrusion of tidal saltwater.The total cancer risk in spring reached 8.23 × 10 ?5 and 8.86 × 10 ?5 for males and females,respectively,which were about two times of those in summer under the experimental conditions.Furthermore,it was found that the presence of Fe(III) resulted in the increased level of THMs and greater cancer risk from exposure to humans.Under weak basic conditions,about 10% of the increment of THMs from the water samples in spring was found in the presence of 0.5 mg/L Fe(III) compared with the situation without Fe(III).More attention should be given to the effect of the coexistence of Fe(III) and bromide ions on the risk assessment of human intake of THMs from drinking water should be paid more attention,especially in the coastland and estuaries. | Shaogang Liu Zhiliang Zhu Chenfeng Fan Yanling Qiu Jianfu Zhao | 2011 | Journal of Environmental Sciences2011，23，9： | 6 |
| 2 | Population genomic analysis reveals domestication of cultivated rye from weedy rye显示文摘Rye(Secale cereale)is an important crop with multiple uses and a valuable genetic resource for wheat breeding.However,due to its complex genome and outcrossing nature,the origin of cultivated rye remains elusive.The geneticist N.I.Vavilov proposed that cultivated rye had been domesticated from weedy rye,rather than directly from wild species like other crops.Unraveling the domestication history of rye will extend our understanding of crop evolution and upend our inherent understanding of agricultural weeds.To this end,in this study we generated the 8.5 Tb of whole-genome resequencing data from 116 worldwide accessions of wild,weedy,and cultivated rye,and demonstrated that cultivated rye was domesticated directly from weedy relatives with a similar but enhanced genomic selection by humans.We found that a repertoire of genes that experienced artificial selection is associated with important agronomic traits,including shattering,grain yield,and disease resistance.Furthermore,we identified a composite introgression in cultivated rye from the wild perennial Secale strictum and detected a 2-Mb introgressed fragment containing a candidate ammonium transporter gene with potential effect on the grain yield and plant growth of rye.Taken together,our findings unravel the domestication history of cultivated rye,suggest that interspecific introgression serves as one of the likely causes of obscure species taxonomy of the genus Secale,and provide an important resource for future rye and wheat breeding. | Yanqing Sun Enhui Shen Yiyu Hu Dongya Wu Yu Feng Sangting Lao Chenfeng Dong Tianyu Du Wei Hua Chu-Yu Ye Jinhuan Zhu Qian-Hao Zhu Daguang Cai Lidia Skuza Jie Qiu Longjiang Fan | 2022 | Molecular Plant2022，15，3： | 1 |
| 3 | Glycogen synthase kinase 3 controls T-cell exhaustion by regulating NFAT activation显示文摘Cellular immunity mediated by CD8+T cells plays an indispensable role in bacterial and viral clearance and cancers.However,persistent antigen stimulation of CD8+T cells leads to an exhausted or dysfunctional cellular state characterized by the loss of effector function and high expression of inhibitory receptors during chronic viral infection and in tumors.Numerous studies have shown that glycogen synthase kinase 3(GSK3)controls the function and development of immune cells,but whether GSK3 affects CD8+T cells is not clearly elucidated.Here,we demonstrate that mice with deletion of Gsk3αand Gsk3βin activated CD8+T cells(DKO)exhibited decreased CTL differentiation and effector function during acute and chronic viral infection.In addition,DKO mice failed to control tumor growth due to the upregulated expression of inhibitory receptors and augmented T-cell exhaustion in tumor-infiltrating CD8+T cells.Strikingly,anti-PD-1 immunotherapy substantially restored tumor rejection in DKO mice.Mechanistically,GSK3 regulates T-cell exhaustion by suppressing TCR-induced nuclear import of NFAT,thereby in turn dampening NFAT-mediated exhaustion-related gene expression,including TOX/TOX2 and PD-1.Thus,we uncovered the molecular mechanisms underlying GSK3 regulation of CTL differentiation and T-cell exhaustion in anti-tumor immune responses. | Yubing Fu Jinjia Wang Chenfeng Liu Kunyu Liao Xianjun Gao Ronghan Tang Binbin Fan Yazhen Hong Nengming Xiao Changchun Xiao Wen-Hsien Liu | 2023 | Cellular & Molecular Immunology2023，20，10： | 0 |
