When input into cells, short hairpin RNA can be cleavaged into siRNAs by Dicer. ShRNA can keep high

我们在体外合成NS特异性短发夹状RNA并转染HL-60细胞，通过观察细胞形态变化和测定NS抑制

Furthermore, calf thymus DNA damage induced by potassium dichromate in combination with Glutathione was studied by AFM and UV.

这种特异性分子印迹介质的制备，为分离提纯特种结合蛋白提供了一种优良的方法，相信其在分离提纯领域将得到越来越广泛的运用。

These results show that codA gene cloned from E. coli can express specifically in the anther of both monocotyledon and dicotyledon plant species upon induction of 5-FC, and the in vivo expression product of the gene can transform the 5-FC used externally into 5-FU, which leads to all or partial inactivity of anthers and/or pollens.

以上结果表明，codA基因在单子叶植物和双子叶植物花药中的特异性表达，能将外用的5-FC在体内转化为5-FU，导致花药或花粉的部分和全部失活。

Twenty-two of these 143 polymorphic bands were found non-special, accounting for 15.4% of the total. It is assumed that they was caused by difference of the conservative sequence.

在上述143条多态性条带中，22条为非特异性条带，占多态性条带总数的15%，它可能与这2个香蕉野生近缘种中差异的保守序列有关。

To sum up, we first conclude that we can isolate mesenchymal stem cells from human fetal articular cartilage and they can be induced to differentiae into several cells under appropriate induction conditions. Anymore, they have their original tissue speciality. Therefore, we first report that mesenchymal stem cells of articular cartilage origin are superior to mesenchymal stem cells of bone marrow origin as seeding cells of cartilage tissue engineering and we provide a kind of new seeding cells of cartilage tissue engineering for the future clinic application.

综上所述，我们首次报道不仅可从人胚胎的关节软骨中获得间充质干细胞，而且软骨来源的间充质干细胞除具有骨髓来源的间充质干细胞的多向分化能力外，还具有其来源的软骨组织特异性，那么，其作为软骨组织工程的种子细胞要优于骨髓来源的间充质干细胞，从而首次提出了一种新型的软骨组织工程的种子细胞，对于未来的软骨组织工程的临床应用提供理论依据。

Differential expression of the protein was demonstrated by Western blotting. The data indicated that the antibody was specific.

本研究制备的SOX4单克隆抗体具有良好的特异性，为进一步研究SOX4在肿瘤发生中的作用提供了重要的工具。

The differential expression of the desired gene in the target tissue is essential for gene therapy.

目的基因在靶组织中的差异表达在基因治疗中很重要，一种方法是用组织特异性启动子驱动治疗基因表达。

Hybridization signals were identified in the nuclei of tumor cells and the positive cells distributed diffusively or focally. Tag expression was found in 75 human brain tumor tissues out of 96 SV40 DNA positive cases. Tag-RB specific complex was found in all of 75 Tag positive cases.

SV40 DNA定位于肿瘤细胞核，阳性细胞呈弥漫或片灶状分布。96例SV40 DNA阳性脑瘤组织Tag表达阳性75例，所有Tag表达阳性瘤组织均发现Tag与RB形成特异性复合物。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
