12019新型冠状病毒基因组特征和流行病学:病毒起源和受体结合的意义显示文摘研究者对来自9例新型冠状病毒肺炎住院患者的支气管肺泡灌洗液样本和培养的分离株进行了下一代测序。从这些个体中获得了严重急性呼吸综合征-冠状病毒2(severe acute respiratory syndrome-coronavirus 2,SARS-CoV-2)的完整和部分基因组序列。利用Sanger测序连接病毒重叠群以获得全长基因组,cDNA末端快速扩增确定终端区。对这些SARSCoV-2基因组和其他冠状病毒基因组进行了系统进化分析,以确定该病毒的进化史并有助于推断其可能的起源。刘青(译) 刘莉(审校) Lu R Zhao X Li J Niu P Yang B Wu H Wang W Song H Huang B Zhu N Bi Y Ma X Zhan F Wang L Hu T Zhou H Hu Z Zhou W Zhao L Chen J Meng Y Wang J Lin Y Yuan J Xie Z Ma J Liu WJ Wang D Xu W Holmes EC Gao GF Wu G Chen W Shi W Tan W 2020中华高血压杂志2020,28,3:516
2Type I IFN augments IL-27-dependent TRIM25 expression to inhibit HBV replication显示文摘Hepatitis B virus(HBV)can cause chronic hepatitis B,which may lead to cirrhosis and liver cancer.Type I interferon(IFN)is an approved drug for the treatment of chronic hepatitis B.However,the fundamental mechanisms of antiviral action by type I IFN and the downstream signaling pathway are unclear.TRIM25 is an IFN-stimulated gene(ISG)that has an important role in RIG-I ubiquitination and activation.Whether TRIM25 is induced in liver cells by type I IFN to mediate anti-HBV function remains unclear.Here we report that interleukin-27(IL-27)has a critical role in IFN-induced TRIM25 upregulation.TRIM25 induction requires both STAT1 and STAT3.In TRIM25 knockout HepG2 cells,type I IFN production was consistently attenuated and HBV replication was increased,whereas overexpression of TRIM25 in HepG2 cells resulted in elevated IFN production and reduced HBV replication.More interestingly,we found that TRIM25 expression was downregulated in HBV patients and the addition of serum samples from HBV patients could inhibit TRIM25 expression in HepG2 cells,suggesting that HBV might have involved a mechanism to inhibit antiviral ISG expression and induce IFN resistance.Collectively,our results demonstrate that type I IFN-induced TRIM25 is an important factor in inhibiting HBV replication,and the IFN-IL-27-TRIM25 axis may represent a new target for treating HBV infection.Guangyun Tan Qingfei Xiao Hongxiao Song Feng Ma Fengchao Xu Di Peng Na Li Xiaosong Wang Junqi Niu Pujun Gao F Xiao-Feng Qin Genhong Cheng 2018Cellular & Molecular Immunology2018,15,3:13
3Polymorphisms of MTHFD,plasma homocysteine levels, and risk of gastric cancer in ahigh-risk Chinese population显示文摘Purpose:Accumulative evidence suggests that folate has a protective effect on gastric cancer. The methylenetetrahyd-rofolate dlehydrogenase(MTHFD) plays an important role in folate and homocysteine metabolisms, and polymorphisms of MTHFD may result in disturbance of the folate-mediated homocysteine pathway. The aim of this study is to test the hypothesis that genetic variants of MTHFD and plasma homocysteine levels are associated with risk of gastric cancer and modulated by genotypes of methylenetetrahydrofolate reductase(MTHFR). Experimental Design: We genotyped G1958A and T401C in MTHFD and C677T in MTHFR and detected total plasma homocysteine(tHcy) levels in a case-control study of 589 gastric cancer cases and 635 cancer-free controls in a high-risk Chinese population. Results:The variant genotypes of MTHFD 1958AA and 401CC were associated with a significantly increased risk of gastric canceradjusted odds ratio(OR), 2.05; 95% confidence interval(95% CI),1.34-3.13 for 1958AA; adjusted OR,1.43; 95% CI,1.14-1.80 for 401CC compared with 1958GG/GA and 401TT/TC genotypes, respectively. Both of the effects were more evident in the subjects carrying MTHFR 677CT/TT genotypes. The average tHcy level was significantly higher in gastric cancer cases than in controls(P < 0.01), and the upper quartile of tHcy (> 13.6 mu mol/L) was associated with an 82% significantly increased risk of gastric cancer, compared with the lowest quartile of tHcy(<= 8.0 pmol/L;adjusted OR,1.82; 95% CI,1.20-2.75). Conclusions:The strong associations between MTHFD variants and the plasma tHcy levels and gastric cancer risk suggest, for the first time, a possible gene-environment interaction between genetic variants of folate-metabolizing genes and high tHcy levels in gastric carcinogenesis.Wang, L.
