Development:利用斑马鱼辨识人类呼吸系统疾病相关的新基因

2014-09-28 佚名 生物谷

在许多热带水族馆中发现的一种小淡水鱼,利用其进行研究可能“解锁”呼吸系统疾病的主要原因。 A*STAR研究所分子和细胞生物学(IMCB)科学家已经在斑马鱼中鉴定出数百个新基因,这些新基因可能在功能上等同于人类基因(后者在运动纤毛,即气道细胞表面上毛发状结构的形成中是必需的)。 运动纤毛有助从人类呼吸道除去灰尘和病原体。该研究表明,这些基因的缺失与运动纤毛缺陷的发生相关,而后者可能是一些呼吸系统疾

在许多热带水族馆中发现的一种小淡水鱼,利用其进行研究可能“解锁”呼吸系统疾病的主要原因。 A*STAR研究所分子和细胞生物学(IMCB)科学家已经在斑马鱼中鉴定出数百个新基因,这些新基因可能在功能上等同于人类基因(后者在运动纤毛,即气道细胞表面上毛发状结构的形成中是必需的)。

运动纤毛有助从人类呼吸道除去灰尘和病原体。该研究表明,这些基因的缺失与运动纤毛缺陷的发生相关,而后者可能是一些呼吸系统疾病的病因。

原发性纤毛运动障碍(PCD)是一种罕见的遗传性疾病,其会导致人体呼吸道内运动纤毛出现缺陷。有缺陷的运动纤毛不能正常运作,即不能从肺中除去灰尘和细菌,这就导致了一系列的呼吸问题,包括慢性肺部感染,如支气管炎和肺炎,并且在严重的情况下,其会导致呼吸道长期损伤。

最近发表在Development杂志上文章中,IMCB研究小组通过斑马鱼基因筛查,确定了数百个与运动纤毛发育有关的新基因。在斑马鱼中,研究者鉴定出近600个基因,其中26个基因为已知的引发PCD的基因。

这一研究发现可以产生有用的信息,以查明与PCD相关的基因。这些基因可能是PCD和运动纤毛其他原因缺陷的有价值的诊断标志物。

目前还没有治愈方法针对PCD开展治疗,医生只能开积极的治疗以减缓气道损伤的进展,并解决PCD导致的呼吸问题,因此重要的是要确定负责PCD的精确基因,同时进行早期诊断。

Chest:呼吸系统疾病焦虑量表可有效评估和筛查COPD患者的焦虑状态

焦虑是慢性阻塞性肺疾病(COPD)患者的常见共病,但这一现象至今仍然被人们所低估。现有的焦虑评估措施多包含有躯体方面的项目,而这些项目常常与COPD本身的症状、及其药物治疗时的副作用症状相重叠,因此有一定的局限性。 为了建立一个具有疾病特异性的非躯体性焦虑量表,用以筛查和评估COPD患者的焦虑状态,来自英国曼彻斯特城市大学医疗卫生系的Abebaw Mengistu Yohannes及其同事进行了
