| 1 | The ER membrane protein complex subunit Emc3 controls angiogenesis via the FZD4/WNT signaling axis显示文摘The endoplasmic reticulum(ER) membrane protein complex(EMC) regulates the synthesis and quality control of membrane proteins with multiple transmembrane domains. One of the membrane spanning subunits, EMC3, is a core member of the EMC complex that provides essential hydrophilic vestibule for substrate insertion. Here, we show that the EMC subunit Emc3 plays critical roles in the retinal vascular angiogenesis by regulating Norrin/Wnt signaling. Postnatal endothelial cell(EC)-specific deletion of Emc3 led to retarded retinal vascular development with a hyperpruned vascular network, the appearance of bluntended, aneurysm-like tip endothelial cells(ECs) with reduced numbers of filopodia and leakage of erythrocytes at the vascular front. Diminished tube formation and cell proliferation were also observed in EMC3 depleted human retinal endothelial cells(HRECs). We then discovered a critical role for EMC3 in expression of FZD4 receptor of β-catenin signaling using RNA sequencing, real-time quantitative PCR(RT-q PCR) and luciferase reporter assay. Moreover, augmentation of Wnt activity via lithium chloride(Li Cl) treatment remarkably enhanced β-catenin signaling and cell proliferation of HRECs. Additionally, Li Cl partially reversed the angiogenesis defects in Emc3-c KO mice. Our data reveal that Emc3 plays essential roles in angiogenesis through direct control of FZD4 expression and Norrin/β-catenin signaling. | Mu Yang Shujin Li Wenjing Liu† Xiao Li Yunqi He Yeming Yang Kuanxiang Sun Lin Zhang Wanli Tian Lixin Duan Huafu Chen Dezhong Yao Zhenglin Yang Xianjun Zhu | 2021 | Science China(Life Sciences)2021，64，11： | 2 |

| 3 | Variants in the Wnt co-receptor LRP6 are associated with familial exudative vitreoretinopathy显示文摘Familial exudative vitreoretinopathy(FEVR),an inherited eye disease,is characterized by abnormal retinal vascular development,such as neovascularization,vitreous hemorrhage,exudation,and retinal detachment(Criswick and Schepens,1969;Robitaille et al.,2002).FEVR is inherited as autosomal dominant,autosomal recessive,and X-linked patterns(de Crecchio et al.,1998). | Shujin Li Mu Yang Yunqi He Xiaoyan Jiang Rulian Zhao Wenjing Liu Lulin Huang Yi Shi Xiao Li Kuanxiang Sun Yeming Yang Periasamy Sundaresan Peiquan Zhao Zhenglin Yang Xianjun Zhu | 2022 | Journal of Genetics and Genomics2022，49，6： | 1 |
| 4 | Loss of Wtap results in cerebellar ataxia and degeneration of Purkinje cells显示文摘N^(6)-methyladenosine(m^(6)A)modification,which is achieved by the METTL3/METTL14/WTAP methyltransferase complex,is the most abundant internal mRNA modification.Although recent evidence indicates that m^(6)A can regulate neurodevelopment as well as synaptic function,the roles of m^(6)A modification in the cerebellum and related synaptic connections are not well established.Here,we report that Purkinje cell(PC)-specific WTAP knockout mice display early-onset ataxia concomitant with cerebellar atrophy due to extensive PC degeneration and apoptotic cell death.Loss of Wtap also causes the aberrant degradation of multiple PC synapses.WTAP depletion leads to decreased expression levels of METTL3/14 and reduced m^(6)A methylation in PCs.Moreover,the expression of GFAP and NF-L in the degenerating cerebellum is increased,suggesting severe neuronal injuries.In conclusion,this study demonstrates the critical role of WTAP-mediated m^(6)A modification in cerebellar PCs,thus providing unique insights related to neurodegenerative disorders. | Yeming Yang Guo Huang Xiaoyan Jiang Xiao Li Kuanxiang Sun Yi Shi Zhenglin Yang Xianjun Zhu | 2022 | Journal of Genetics and Genomics2022，49，9： | 1 |
| 5 | Long-term outcomes in COVID-19 patients who recovered from the first wave of the pandemic显示文摘This cross-sectional study evaluated the long-term health effects of coronavirus disease 2019(COVID-19)in Jianghan District(Wuhan,China).The results showed that 61.4%of COVID-19 patients reported at least one symptom and 8.8%had depressive symptoms at the 17-month follow-up.The proportion of patients with chest radiographic abnormalities in Fangcang shelter hospitals and designated COVID-19hospitals was 31.6%and 41.1%,respectively,and the proportion of patients with impaired pulmonary diffusion capacity in these hospitals was 52.8%and 60.9%,respectively.Female sex(odds ratio[OR]=1.48,95%confidence interval[CI]:1.16–1.88),severe disease(OR=1.46,95%CI:1.01–2.10)and a higher number of initial symptoms(OR=1.31,95%CI:1.23–1.40)were associated with the development of sequelae symptoms at 17 months.This study involving community-dwelling COVID-19adults may help determine the long-term effects of COVID-19 during the first pandemic wave.Nonetheless,larger follow-up studies are needed to characterize the post-COVID-19 condition. | Dan Cui Simiao Chen Luzhao Feng Mengmeng Jia Yeming Wang Weijun Xiao Yanxia Sun Qiangru Huang Libing Ma Zhiwei Leng Hao Wang Bin Cao Weizhong Yang Juntao Yang Chen Wang | 2022 | National Science Review2022，9，11： | 0 |
