Both vectors were stable in host cells tested and could be generally useful for expressing heterologous genes.

两种载体在宿主细胞中是稳定的，应可用于异源基因的表达。

A method for the recombinant production of a heterologous polypeptide in a eukaryotic host cell is described.

本发明描述了用于在真核宿主细胞中重组产生异源多肽的方法。

TGF-βbinds to a heteromeric complex of type I and type II receptors. The constitutively active type II receptor phosphorylates and activates the type I receptor which phosphorylates Smad2 and Smad3 (receptor-associated Smads). Receptor-associated Smads bind the common mediator Smad4 and are translocated to the nucleus, where they associate with DNA-binding cofactors to modulategene transcription.

TGF-β与其效应细胞表面的Ⅱ型受体TβRⅡ和Ⅰ型受体TβRⅠ形成的异源二聚体结合，相继激活TβRⅡ和TβRⅠ，活化的TβRⅠ再进一步活化Smad2和Smad3，磷酸化的Smad2/3必须与Smad4结合形成复合物，才能进入细胞核，调节靶基因的转录[6]。

As a test of cell growth potential a hyperplastic reaction of the tissues of salivary glands on isoproterenol was used (mass increase in 24 hours).

以测试的细胞生长潜力，对在使用异丙肾上腺素时唾液腺组织的增生反应（大规模增加在 24小时内）。

In addition,the number of idioblastic cells in the stem slices of transgeinic L.bicolor with antisense 4CL-BADH was more than those of wild-type L.bicolor.

此外，转入反义4CL-BADH的二色胡枝子茎段皮层组织中含有的异形细胞数量明显比对照多。

These results suggested that LMP1-CTAR3 is the important activating domain of inducing cellular proliferation and the domain probably plays the role of mediating to regulate the expression of G-protein, isocitric enzyme, and so on.

以上结果说明，LMP1-CTAR3是其发挥促细胞增殖的重要活性部位，可能通过参与调节G蛋白和异柠檬酸脱氢酶等蛋白质的表达而起作用。

Objective To analyse the vasodilative mechanism of isocorydine, its effects on the increasing of the cytosolic free Ca 2+ level ([Ca 2+ ]i) induced by noradrenaline and high potassium in the blood vessel smooth muscle cells were investigated.

目的 观察扩血管药异紫堇啡碱对去甲肾上腺素和高钾所致血管平滑肌细胞内游离钙浓度([Ca2 + ]i)增高的影响，分析该药扩血管作用的原理。

Objective To analyse the antiarrhythmic mechanism of isocorydine,its effects on the increasing of the cytosolic free Ca 2+ level ([Ca 2+ ] i) induced by noradrenaline and high potassium in the cultural newborn rat beart cells were investigated.

目的 观察异紫堇啡碱对去甲肾上腺素和高钾所致培养乳鼠心肌细胞内游离钙浓度([Ca2 + ]i)增高的影响，初步分析该药心脏效应的作用原理。

Objective To investigate whether novel isoflavone and steroid derivatives have better antitumor activity.

目的 研究改构后的异黄酮及甾体类化合物是否具较好的体外抗细胞增殖的活性。

In their new work, the researchers established a genetic connection between male sexuality of an oogamous multicellular green algae species, Pleodorina starrii, and one of the mating types of its isogamous ancestor, the unicellular alga Clamydomonas reinhardtii.

在这项最新研究中，研究人员让一种异配生殖多细胞绿藻（Pleodorina starrii藻）与其同配生殖单细胞祖先（Clamydomonas reinhardtii藻）的其中一种配子类型进行雄性配子结合，从而建立两种藻类的遗传学联系。
