目的:探讨Mirk/Dryk1b(Minibrain-related kinase/Dual specificity tyrosine-phosphorylation-regulated kinase1B)在卵巢组织中的表达及其临床意义。方法:利用免疫组化检测Mirk/Dyrk1b在30例上皮性卵巢癌、20例上皮性卵巢囊腺瘤、10例正常卵巢组织中的表达。结果:Dyrk1b在上皮性卵巢癌中的表达明显高于上皮性卵巢囊腺瘤及正常卵巢组织(P0.05)。结论:Dyrk1b在上皮性卵巢癌中高表达,提示其可能参与了肿瘤的发生和发展,并有望成为临床早期诊断的肿瘤标志物和新的卵巢癌治疗的靶基因

“建筑适应性”主题沙龙

"地域建筑"是当下建筑学界共同尊重的准则,但这一术语的过度使用,也使得其内涵在当代建筑创作中逐渐模糊。本期沙龙主题"建筑适应性",是对"地域建造"这一命题的具体化。"适度"的"适应"是当下应当倡导的地域建筑设计创作原则。"建筑适应性"中的"适应",强调对历史文脉与所处环境的积极回应,研究建筑与环境之间的复杂应答关联;除此,"建筑适应性"还强调对经济、技术、材料的"适度

分子对接预测H5亚型禽流感病毒的广谱中和表位

H5N1禽流感病毒已经在亚洲、欧洲和非洲广泛传播,造成了巨大损失.最近我们鉴定出一株对多种来源的H5N1代表株均有良好中和活性的、识别H5亚型血凝素(hemagglutinin,HA)的广谱单克隆抗体8H5,它对寻找克服禽流感高变性的广谱治疗性抗体、疫苗和药物具有重要价值.本研究应用分子模拟技术,采用"典范结构"方法对8H5抗体Fab片段进行结构模建,并通过能量分析、SAS值分析、"拉曼强传图"检验、profile-3D分析等理论验证,获得较为合理的8H5Fab的三维空间结构.8H5Fab与3种HA蛋白晶体结构的分子对接结果表明,8H5抗体与HA蛋白的作用模式与HA宿主来源无关,但与HA结构的亚型相似性相关.综合抗原同源比对结果,推测8H5抗体识别的广谱中和表位是由HA上的Asp68,Asn72,Glu112,Lys113,Ile114,Pro118,Ser120,Tyr137,Tyr252不连续氨基酸残基组成的构象表位.这一模型将为H5亚型禽流感病毒广谱疫苗和治疗性药物的分子设计提供依据
