项目摘要
To identify Pet-1 (serotonergic neuron-specific transcription factor)-binding sites in rat raphe nucleus-derived RN46A cells, chromatin-immunoprecipitation (ChIP) assays were performed. It was revealed that Pet-1 binding was inhibited through the neuron-restrictive silencer factor(NRSF)-NRSF binding element(NRSE) system or the potential repressor proteins independent of NRSF. Additionally, the detection of Pet-1 binding to target genes was occasionally difficult even under conditions where Pet-1 was overexpressed. Taken together, to exclude the function of repressor proteins including NRSF may be necessary to identify the Pet-1 binding to its target genes by ChIP assays in RN46A cells. To overcome these difficulties should be required to use RN46A cells as a proper model of central serotonergic neurons and characterize the Pet-1-mediated transcriptional network in serotonergic neurons.
为了鉴定大鼠raphe核源性的RN46A细胞中的PET-1(血清素能特异性转录因子) - 结合位点,进行了染色质免疫沉淀(芯片)测定。 据表明,PET-1结合通过神经限制性的消音器因子(NRSF)-NRSF结合元件(NRSE)系统抑制了PET-1结合,或独立于NRSF的潜在抑制蛋白。 另外,即使在PET-1过表达的条件下,DET-1与靶基因的结合也有时也很困难。 综上所述,为排除包括NRSF在内的阻遏蛋白的功能,对于通过RN46A细胞中的CHIP分析鉴定PET-1与其靶基因的结合可能是必要的。 为了克服这些困难,应使用RN46A细胞作为中央血清素能神经元的正确模型,并表征PET-1介导的转录网络中的5-羟色源性神经元中的转录网络。
