1Type 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
2A long-form α-neurotoxin from cobra venom produces potent opioid-independent analgesia显示文摘Aim:In light of the antinociceptive activity of the short-chain neurotoxin,cobrotoxin,and other acetylcholine antagonists,the antinociceptive activity andmechanisms of cobratoxin(CTX),a long-chain postsynaptic α-neurotoxin,wasinvestigated in rodent pain models.Methods:CTX was administered intraperito-neally(30,45,68 μg/kg),intra-cerebral ventricularly(4.5 μg/kg)or microinjectedinto periaqueductal gray(PAG;4.5 μg/kg).The antinociceptive action was testedusing the hot-plate and acetic acid writhing tests m mice and rats.The involve-ment of the cholinergic system and opioid system in CTX-induced analgesia wasexamined by pretreatment of animals with atropine(0.5 mg/kg,im;or 10 mg/kg,ip)or naloxone(1 and 5 mg/kg,ip).The effect of CTX on motor activity was testedusing the Animex test.Results:CTX exhibited a dose-dependent analgesic ac-tion in mice as determined by both the hot-plate and acetic acid writhing tests.The peak effect of analgesia was seen 3 h after administration.In the mouse aceticacid writhing test,the intra-cerebral ventricular administration of CTX at 4.5 μg/kg(1/12th of a systemic dose)produced marked analgesic effects.Microinjection ofCTX(4.5 μgkg)into the PAG region did not elicit an analgesic action in rats in thehot-plate test.Atropine at 0.5 mg/kg(im)and naloxone at 1 and 5 mg/kg(ip)bothfailed to block the analgesic effects of CTX,but atropine at 10 mg/kg(ip)didantagonize the analgesia mediated by CTX in the mouse acetic acid writhing test.Acetylsalicylic acid(300 mg/kg)did not enhance the analgesic effects of CTX.Atthe highest effective dose of 68 μg/kg the neurotoxin did not change the sponta-neous mobility of mice.Conclusion:CTX has analgesic effects,which are medi-ated in the central nervous system though not through the PAG.The centralcholinergic system but not opioid system appears to be involved in theantinociceptive action of CTX.Zhi-xin CHEN Hui-ling ZHANG Zhen-lun GU Bo-wen CHEN Rong HAN Paul F REID Laurence N RAYMOND Zheng-hong QIN 2006Acta Pharmacologica Sinica2006,27,4:7

5东方蜜蜂高效的卫生行为机制对于西方蜜蜂抗病育种的启示显示文摘西方蜜蜂(Apismellifera)在世界各地大范围的蜂群损失现象已引起科学界和公众的广泛关注,其健康状况与东方蜜蜂(Apis cerana)相比明显较劣。东方蜜蜂群内可检测到的病原体和寄生虫相对较少,即它们对于生物威胁具有更强的抵抗力,即便是面对异种入侵的新病原(如蜜蜂残翅病毒)。Lin Z Page P Li L Qin Y Zhang Y Hu F Neumann P Zheng H Dietemann V 蔺哲广 郑火青 胡福良 2016中国蜂业2016,67,12:5

10Common non-synonymous polymorphisms in the BRCA1 Associated RING Domain (BARD1) gene are associated with breast cancer susceptibility:a case-control analysis显示文摘The BRCA1 Associated RING Domain(BARD1) gene has been identified as a high penetrance gene for breast cancer, whose germline and somatic mutations were reported in both non-BRCA1/2 hereditary site-specific and sporadic breast cancer cases. BARD1 plays a crucial role in tumor repression, along with its heterodimeric partner BRCA1. In the current study, we tested the hypothesis that common non-synonymous polymorphisms in BARD1 are associated with breast cancer susceptibility in a case-control study of 507 patients with incident breast cancer and 539 frequency-matched cancer-free controls in Chinese women. We genotyped all three common(minor allele frequency (MAF) > 0.10) non-synonymous polymorphisms(Pro24Ser, Arg378Ser, and Val507Met) in BARD1. We found that the BARD1 Pro24Ser variant genotypes(24Pro/Ser and 24Ser/Ser) and Arg378Ser variant homozygote 378Ser/Ser were associated with a significantly decreased breast cancer risk, compared with their wild-type homozygotes, respectively. Furthermore, a significant locus-locus interaction was evident between Pro24Ser and Arg378Ser (P-int = 0.032). Among the 378Ser variant allele carriers, the 24Pro/Pro wild-type homozygote was associated with a significantly increased breast cancer risk (adjusted OR = 1.81, 95% CI = 1.11-2.95), but the subjects having 24Pro/Ser or Ser/Ser variant genotypes had a significantly decreased risk(adjusted OR = 0.74, 95% CI = 0.56-0.99). In stratified analysis, this locus-locus interaction was more evident among subjects without family cancer history, those with positive estrogen receptor (ER) and individuals with negative progesterone receptor(PR). These findings indicate that the potentially functional polymorphisms Pro24Ser and Arg378Ser in BARD1 may jointly contribute to the susceptibility of breast cancer.Huo, X Hu, Z. B Zhai, X.
