    Bmp一2 、 afra 、 vd3和dex對神經幹細胞分化的誘導作用與ra受體mrna表達量的改變沒有相關性
  4. The ratio of ( s + g2 ) / ( g2 + m + s ) and pi value of mc - 3t3 - el cells increased in the condition of 1um / l e2. the effects of e2 on igfbp - 6 and igf - 2 gene expressions were suppressed by tcdd and ra. the binding of ere at higfbp - 6 5 " - utr ( dna sequence : aactctgacc, + 94 to + 103 ) was enhanced by tcdd

    第三部分igfbp一6基因5 』一utr中ere的鑒定及功能分析目的:骨骼組織起源於胚胎期中胚層，維持正常的胚胎期骨骼發育需要多種生長因子、細胞因子和激素的參與，其中雌激素可通過多種途徑作用子中胚層內間
  5. Tcdd influence the activity of diverse hormones, hormone receptors, mitogens, and other biological response modifiers and these interactions undoubtedly play an important role in the toxicity of these response. retinoic acid ( ra ) is ramification of vitamin a, having extensive biological effect on controlling conformation genesis, proliferation, differentiation, growth, metabolism of kinds of tissues and cells and stabilization of internal environment

    第一部分igfs家族成分在維甲酸誘導馬蹄內翻足畸形中的調控機制目的：維甲酸（ retinoicacid ， ra ）類物質是維生素a的衍生物，在調控多種組織和細胞的形態發生、增殖分化、生長發育、代謝及維持內環境的穩定等方面具有廣泛的生物學活性。
  6. Recent studies indicate that the mechanism to this process is complicated and needs further exploration with sophisticated microarray approaches. on the bases of this model, we prepared cdna microarray with restriction display ( rd ) technique and studied the gene expression profile changes of sh - sy5y cells after treatment with ra with our self - made microarrays

    本課題根據這一線索，採用馬文麗、鄭文嶺等建立的rd技術制備sh - sy5y細胞基因表達譜晶元，在基因晶元的制備上做了一些研究，同時應用自製的基因表達譜晶元，研究了ra誘導sh - sy5y細胞分化的基因表達變化。
  7. Retinoic acid ( ra ), as a non - specific inducer, has been implied into the research on induction of es cells

    維甲酸（ retinoicacid ， ra ）作為一種非特異性的誘導劑被廣泛用於es細胞誘導研究中。
  8. Via suspension culture and 0. 5 mol l ra induction, we established an in vitro system to differentiate es cells directly into neuron - like cells. in this system, neuron - like cells first appeared within 48h after the embryoid bodies were plated, and were most abundant 4 - 6 days after plating, while decreased 8 - 10 days later. neuron - like cells differentiated from es cells had typical morphologic properties, and specifically reacted with nf antibodies

    通過懸浮培養和0 . 5mol l ra誘導，建立了定向誘導es細胞向神經元樣細胞分化的體系。在該體系中，神經元樣細胞于類胚貼壁后48h之內出現， 46d時達到最多， 810d后減少。由es細胞分化而來的神經元樣細胞具有典型的形態特徵，並且可以與nf抗體發生特異反應。
  9. The ebs of different days gained by means of hanging, suspending and suspending following hanging were processed by all - trans retinoic acid ( ra ) for 4 days. during this period, we observed the differentiation process and compared the differentiation ratio of es cells processed by means of hanging, suspending for several days. based on this study, we induced the ebs by ra of different concentration in order to study the effect of ra on the differentiation of es cells into neuron - like cells

    首先從胚體（ ebs ）本身探討es細胞內部調控誘導分化的機制，用懸浮培養、懸滴培養、懸浮轉懸滴培養的方法培養出不同時間的ebs ，再加以ra處理，觀察比較ebs對es細胞神經分化的影響；在此基礎上，用不同濃度的ra處理ebs ，分析誘導劑ra對es細胞神經分化的影響。
  10. In vitro model system, they found that stable - transfected cell lines which are over - express wnt - 1 or n - cadherin gene could differentiate into neuron - like cells without ra induction

    目前從事的主要研究工作有：小鼠巢蛋白基因表達調控的分子機制；胚胎性癌細胞
  11. The laboratory animal studies on tcdd and ra exposure indicated high incidences of congenital developmental malformations. in our previously study, we analyzed gene expression profile in igf gene family of tcdd - and ra - reduced fetal rats as well as cells and found antiestrogenic effect of tcdd and ra on igf genes

    我們應用ra對不同發育時期的胎鼠進行誘導，構建骨骼發育畸形大鼠動物模型，研究遺傳因素決定的先天畸形個體間對環境因素作用的易感性，闡明igfs家族成員在骨骼發育畸形大鼠中的作用。
