查询词典 promoter

In present study, we discussed the effects of cell microfilament on the activity of collagen type I alpha 1 chain gene (COL1A1) promoter under microgravity simulated by clinostat and/or cytochalasin B as microfilament depolymerizer in the established EGFP-ROS cell line using the method of fluorescence semi-quantitative analysis and the fluorescent stain of microfilament.

BACKGROUND: Preliminary study shows that the FHL1 gene expression is down-regulated in muscle tissue of patients with clubfoot, and the gel retardation experiments have verified HOXD13 and FHL1 gene promoter region transcription factor predicted binding sites in vitro, but the experimental results are not enough to truly reflect in vivo transcriptional regulatory protein and DNA binding conditions.

摘要背景：前期研究表明，在马蹄内翻足患者肌肉组织中存在FHL1基因表达下调，并利用凝胶阻滞实验在体外初步验证了HOXD13和FHL1基因启动子区转录因子预测位点的结合作用，但凝胶阻滞实验结果不一定能真实地反映体内转录调控蛋白和DNA结合的状况。

Common promoter element in E. coli.
