摘要

研究了阿霉素和α-amanitin对小鼠着床前胚胎DNA合成的影响。结果表明,在20 ~ 50 μg/ml浓度下,阿帕迪克林对囊胚和8细胞胚胎中3h -胸腺嘧啶的掺入均有明显的抑制作用。然而,阿菲霉素并没有抑制桑葚胚向囊胚的转化,尽管阿菲霉素处理的囊胚在长时间暴露于药物后失去了囊胚腔并塌陷成致密的形式。8细胞和囊胚胚均易受α-amanitin抑制DNA合成的影响。

The effects of aphidicolin and α-amanitin on DNA synthesis in preimplantation mouse embryos
The effects of aphidicolin and α-amanitin on DNA synthesis by preimplantation mouse embryos were studied. It was found that both blastocyst and 8-cell embryos showed marked inhibition of 3H-thymidine incorporation into DNA by aphidicolin at concentrations of 20–50 μg/ml. However, aphidicolin did not inhibit the conversion of morula embryos to blastocyst embryos, although aphidicolin-treated blastocysts lost their blastocoel and collapsed into a compact form after prolonged exposure to the drug. Both 8-cell and blastocyst embryos were found to be susceptible to inhibition of DNA synthesis by α-amanitin.
