    • 摘要: Objective This study was designed to determine the methylation profile of four CpGs and the genotypes of two CpG-SNPs located in promoter region of DIO2 in patients with Kashin-Beck disease(KBD).We also analyzed the interaction between the CpGs methylations and CpG-SNPs.Methods Whole blood specimens were collected from 16 KBD patients and 16 healthy subjects.Four CpGs and two CpG-SNPs in the promoter regions of DIO2 were detected using matrix-assisted laser desorption ionization time of flight mass spectrometry(MALDI-TOF-MS).The CpGs methylation levels were compared between samples from KBD patients and healthy subjects.The methylation levels were also analyzed in KBD patients with different CpG-SNP genotypes.Results The mRNA expression of DIO2 in whole blood of KBD patients was significnatly lower than in healthy controls(P<0.05).The methylation levels of DIO2-1_CpG_3 in KBD patients were significantly higher than those in healthy controls(P<0.05).The methylation levels of four CpGs were not significantly different between KBD patients and healthy controls.The methylation level of DIO2-1_CpG_3 in the promoter region of DIO2 in KBD patients with GA/AA genotype was significantly higher than that of KBD patients with GG genotype(P<0.05).Conclusion The methylation level of DIO2 increases in KBD patients.Similar trends exist in KBD carriers of variant genotypes of CpG-SNPs DIO2 rs955849187.

    • 摘要: 为了预防和应对新型鸭呼肠孤病毒引起的综合疾病,本研究利用分离到的新型鸭呼肠孤病毒,制备了具有良好中和活性的高效价IgY。中和试验结果显示:三免后第14天抗体滴度达到峰值,而后趋于平稳(>26),且添加CpG和IL-2分子佐剂的组别提取的IgY比未添加分子佐剂的组别中和滴度提高约3倍;将抗体注入SPF鸡胚进行攻毒保护试验,结果显示中和组的保护率最高,预防组的略高于治疗组的,且CpG组所提取的IgY预防效果(83%)和治疗效果(75%)最佳。本研究提取的高效价IgY能应用到临床防控中,可有效预防及治疗新型鸭呼肠孤病毒病。

    • 摘要: 中枢模式发生器(Central pattern generators, CPG)是动物运动神经网络的重要组成部分。大量研究表明CPG在节律运动(行走、呼吸、吞咽等)中发挥着至关重要的作用。本文主要总结归纳了过去CPG与节律运动相关的研究,可为了解或深入研究CPG提供参考借鉴。

    • 摘要: Macrophages are important antigen-presenting cells to combat tumor via both innate and adaptive immunity,while they are programmed toM2 phenotype in established tumors and instead promote cancer development and metastasis.Here,we develop a nanomedicine that can re-educate M2 polarized macrophages to restore their anti-tumor activities.The nanomedicine has a core-shell structure to co-load IPI549,a PI3Kγinhibitor,and CpG,a Toll-like receptor 9 agonist.Specifically,the hydrophobic IPI549 is self-assembled into a pure drug nano-core,while MOF shell layer is coated for CpG encapsulation,achieving extra-high total drugs loading of 44%.Such nanosystem could facilitate intracellular delivery of the payloads but without any cytotoxicity,displaying excellent biocompatibility.After entering macrophages,the released IPI549 and CpG exert a synergistic effect to switch macrophages from M2 to M1 phenotype,which enables anti-tumor activities via directly engulfing tumor cells or excreting tumor killing cytokines.Moreover,tumor antigens released from the dying tumor cells could be effectively presented by the re-educated macrophages owing to the up-regulation of various antigen presenting mediators,resulting in infiltration and activation of cytotoxic T lymphocytes.As a result,the nanosystem triggers a robust antitumor immune response in combination with PD-L1 antibody to inhibit tumor growth and metastasis.This work provides a non-cytotoxic nanomedicine to modulate tumor immune microenvironment by reprograming macrophages.

    • 摘要: 目的 寻找肺栓塞患者差异甲基化CpG位点、甲基化区域及其所对应的目的基因,探讨DNA甲基化在肺栓塞发生中的作用.方法 收集2019年1月至2019年12月新疆医科大学附属肿瘤医院确诊的单纯肺栓塞患者和正常对照人群外周血标本各10例,提取DNA,采用Illumina Infinium Methylation EPIC Bead Chip芯片(850K芯片)甲基化检测平台于全基因组水平检测肺栓塞组及正常对照组甲基化位点,利用R包Limma进行两组差异甲基化位点分析,采用Bumphunter的方法寻找两组差异甲基化区域.结果 ①肺栓塞组与正常对照组对比分析,共筛选到95286个有意义的差异C pG位点(P<0.05),其中37983个为高甲基化,57303个为低甲基化;对应28273个目的基因,其中13785个为高甲基化,14488个为低甲基化.显著差异CpG位点在CpG岛的分布情况为:CpG岛29%(27483)、Shore 18%(16700)、Shelf 6%(6011)、Open sea 47%(45092).②采用Bumphunter的方法寻找差异甲基化区域,结果筛选出两组差异甲基化区域DMR-1、DMR-2,分别位于3号染色体(195489708-195490309)和6号染色体(49681178-49681774)上(均P<0.05).DMR-1宽度601 bp,DMR-2宽度596 bp,DMR-1包含8个CpG位点(cg23170091、cg18918831、cg16034541等),其所属的簇包含8个CpG位点,DM R-2包含11个CpG位点(cg01706515、cg14997592、cg26715042等),其所属的簇包含11个CpG位点,且肺栓塞组DM R-1与DM R-2所有CpG位点甲基化水平均较正常对照组高.DM R-1目的基因为MUC4,DMR-2目的基因为CRISP2.结论 DNA的高甲基化可能参与了肺栓塞的发生,差异较大的CpG位点cg06417478、cg18105134及其目的基因HOOK2、PROZ和DM R-1、DM R-2中包含的差异CpG位点及其目的基因M UC4、CRISP2的异常甲基化,或许在肺栓塞的发生中起到重要的作用.
