| 1 | Complement C7 is a novel risk gene for Alzheimer's disease in Han Chinese显示文摘Alzheimer's disease is the most common neurodegenerative disease,and has a high level of genetic heritability and population heterogeneity.In this study,we performed the whole-exome sequencing of Han Chinese patients with familial and/or early-onset Alzheimer's disease,followed by independent validation,imaging analysis and function characterization.We identified an exome-wide significant rare missense variant rs3792646(p.K420Q)in the C7 gene in the discovery stage(P=1.09×10^(-6),odds ratio=7.853)and confirmed the association in different cohorts and a combined sample(1615 cases and 2832 controls,P_(combined)=2.99×10^(-7),odds ratio=1.930).The risk allele was associated with decreased hippocampal volume and poorer working memory performance in early adulthood,thus resulting in an earlier age of disease onset.Overexpression of the mutant p.K420Q disturbed cell viability,immune activation and β-amyloid processing.Electrophysiological analyses showed that the mutant p.K420Q impairs the inhibitory effect of wild type C7 on the excitatory synaptic transmission in pyramidal neurons.These findings suggested that C7 is a novel risk gene for Alzheimer’s disease in Han Chinese. | Deng-Feng Zhang Yu Fan Min Xu Guihong Wang Dong Wang Jin Li Li-Li Kong Hejiang Zhou Rongcan Luo Rui Bi Yong Wu Guo-Dong Li Ming Li Xiong-Jian Luo Hong-Yan Jiang Liwen Tan Chunjiu Zhong Yiru Fang Chen Zhang Nengyin Sheng Tianzi Jiang Yong-Gang Yao | 2019 | National Science Review2019，6，2： | 6 |
| 2 | Rapid Access to Oxabicyclo[2.2.2 ]octane Skeleton through Cu(I)- Catalyzed Generation and Trapping of Vinyl-o-quinodimethanes (Vinyl-0-QDMs)显示文摘Summary of main observation and conclusion A Cu(I)-catalyzed three-component reaction of terminal enynals/enynones,diazo compounds,and al kenes has been developed.With this method,a series of oxabicyclo[2.2.2]octanes were effectively synthesized in high yields under mild reaction condi-tions.This transformation is proposed to proceed through trapping of the cyclic vinyl-o-quinodimethanes(vinyI-o-QDMs)species,which were generated from terminal enynals/enynones and diazo compounds by alkenes.The obvious advantages of wide substrate scopes,mild reaction conditions,and high seteroselectivity and atom eficiency make this reaction highly appealing for construction of highly rigid[2.2.2]octane skeleton. | Hejiang Luo Chuan He Huanfeng Jiang Shifa Zhu | 2020 | Chinese Journal of Chemistry2020，38，10： | 0 |
