为了证明在成形过程中是否也具有相似的分子机制，我们通过原位杂交同体内表达比对的方法来检查小鼠胚胎中调节内胚层和肠道发育的转录因子的表达模式。

To date, three kinds of reverse genetics systems, in vitro transcription system, system induced by endogeny T7 RNA polymerase and system induced by RNA polymeraseⅡ, were used to research IBDV. But these systems have some shortcomings in the efficiency and convenience of virus rescue.

目前用于IBDV研究的体外转录、基于T7RNA聚合酶的体内转录、RNA聚合酶Ⅱ体内转录等反向遗传操作系统在病毒拯救效率和操作简便性等方面仍然存在着一些问题。

Methods Expressions of MMP2 and TGF-β1 gene from 43 human suprarenal epithelioma patients' carcinoma and tumor-adjacent tissues were detected by semi-quantitative reverse transcription polymerase chain reaction.

应用半定量逆转录－聚合酶链反应检测43例肾透明细胞癌患者癌与癌旁组织MMP2和TGF-β1的表达水平。

Methods: Three aspects were studied in the epithelization of skin of PAI-3 with the techniques of Immunohistochemistry,Immunocytochemistry,RT-PCR and the analysis of PAI-3 in cornified envelope.

采用免疫组织化学(Immunohistochemistry，IHC)、(Immunocytochemistry，ICC)和逆转录-聚合酶链反应(reverse transcription PCR，RT-PCR )技术及KC角质壳的提取，从三个方面研究了PAI-3 在人皮肤上皮化中的表达及作用。

Erratum to: Characterization of transcription factor gene SNAC2 conferring cold and salt tolerance in rice.

An O2-labile protein (hypoxia-inducible factor 1, HIF-1) has been identified that is hydroxylated and degraded under normoxic conditions but actie in hypoxia, where it enhances Epo gene transcription resulting in eleated hemoglobin leels and O2 capacity of the blood. The stimulation of Epo production at lowered arterial O2 tension can be maladaptie, if erythrocytosis deelops such as seen in high altitude habitants.

此途径因提高了体内血红蛋白水平，加强了epo基因转录和氧运输能力。epo 在动脉低氧情况下的产生使机体不适应－－这种情况就如同世居高原人群中的细胞因子发生变化一样。

Erythropoiesis is a complicated process, which is controlled by the combined effects of growth factors and transcription factors.

红细胞的生成是一个颇为复杂的过程，其和谐调控是多因素共同作用的结果，包括造血生长因子，转录因子等。

With the supplementation of ethanolamine, the transcription efficiency of HBsAg gene decreased but the antigen unit expressed was improved.

优化操作条件提高重组酿酒酵母发酵生产HBsAg的效率已有许多文献报道[1～5]，本文通过对HBsAg表达中的几

Euchromatin is thought to be actively involved in transcription and therefore protein synthesis, while heterochromatin is inavtive.

异染色质由于折叠压缩程度高，所以被碱性染料染色时着色较深。

Most genes reside in euchromatin, which is of relatiely low density and where the DNA is more accessible to the machinery of gene transcription.

大多数基因位于常染色质，结构相对疏松，DNA更易被转录。
