首先，他们用基因手段禁止了细胞受体的活动——细胞受体即那些向其他细胞发送和从其他细胞接受信号的分子们——因为雌激素和雄激素存在于正在发育的老鼠胚胎的肢芽中。

First, they used genetic tools to deactivate cell receptors-molecules that send and receive signals to and from other cells-for testosterone and estrogen in the developing limb buds of mouse embryos.

此外，在ER+/PR+（雌激素受体阳性/孕激素受体阳性）恶性肿瘤和接受阿那曲唑作为内分泌治疗的患者中，发现了（大豆异黄酮和绝经妇女乳腺癌复发率之间）相反的关联。

Additionally, inverse associations were found in those who wee diagnosed with ER+/PR+ malignancy and those who receiving anastrozole as endocrine therapy.

载体经修改后包括带有一合成的剪接供体的一个异种内含子， 此供体经促性腺激素a亚单位基因（含有一个剪接受体）的内含子A中某片段的上游改造。

The vector was modified to include a heterologous intron with a synthetic splice donor engineered upstream of a fragment from intron A of the gonadotropin a subunit gene(containing a splice acceptor).
