本文提出将秀丽线虫作为研究多世代化学效应的模式生物。我们调查了线虫是否对脊椎动物类固醇激素有反应。我们发现雌激素类类固醇,特别是雌二醇(E2),在支持线虫繁殖方面具有类胆固醇的效力。相比之下,睾酮(TS)和己烯雌酚(DES)则没有表现出这种效力。另一方面,当用胆固醇进行培养时,E2、TS和DES抑制了线虫的繁殖率。此外,与所测试的其他化学物质相比,TS的效果随着世代积累而增加。这些数据表明,线虫具有繁殖力等方便的生物标志物,可能是研究包括繁殖中断在内的化学反应的有效模式生物。
In this paper, Caenorhabditis elegans (C. elegans) is proposed as a model organism for studying chemical effects over multiple generations. We investigated whether C. elegans responds to vertebrate steroid hormones. We found that estrogenic steroids, especially estradiol (E2), have a cholesterol-like potency in supporting the reproduction of C. elegans. In contrast, testosterone (TS) and diethylstilbestrol (DES) did not display this potency. On the other hand, E2, TS and DES supressed the fecundity rate of C. elegans, when culture carried out with cholesterol. Moreover effect of TS accumulated over generation, in contrast to the other chemicals tested. These data suggested that with convenient biomarkers such as fecundity, C. elegans might be an effective model organism for studying chemical actions, including the disruption of reproduction.
