Hypertension:实验设计时选雄性还是雌性动物?

2016-10-20 xing.T MedSci原创

由此可见,雄性和雌性大鼠之间142个表型的变异是相似的,这表明,不同治疗专门区分雄性和雌性个体的实验设计的目的是没有必要的,除非,有确切证据需要区分雄雌个体,否则,属于自找麻烦。

尽管雄性和雌性生理之间存在显著差异,而且雌性生理仍处在研究中。对此,美国国家卫生研究院(NIH)颁布的新政策以期提高雌性个体在临床前研究的比例。由于受月经周期的影响,雌性个体通常被认为比雄性有更大的变异,但最近心血管权威杂志《Hypertension》上发表研究文章对这种认识提出了质疑。

研究者通过遥感测压和阴道细胞学检查等手段评估月经周期对雌性大鼠平均动脉压的影响,研究者发现月经周期不影响平均动脉压的大小或变异程度。从基因组应用计划的子计划PhysGen中提取数据,比较雄性和雌性大鼠的心脏、肺脏、血管、肾脏以及血型等142个表型的变异情况和变异系数,每个表型都是从来自50多个近交系大鼠成百上千的个体上进行测量。从这个数据集中发现142个表型中有74个存在性别差异,而且这些存在性别差异表型中有59%雄性个体变异比雌性个体更为明显。值得注意的是,回顾性分析表明,在74个存在性别差异的表型中只有16个表型需要使用足够大的实验性队列才能检测到有统计学意义的变异幅度。在整体分析这142种表型时,雄性和雌性大鼠的变异系数并不存在总体差异。

由此可见,雄性和雌性大鼠之间142个表型的变异是相似的,这表明,不同治疗专门区分雄性和雌性个体的实验设计的目的是没有必要的,除非,有确切证据需要区分雄雌个体,否则属于自找麻烦。
