We analyzed the mRNA diversity of genes after inducing neuronal differentiation in human NT2 teratocarcinoma cells using all-trans retinoic acid (RA). DNA microarray analyses of cells treated with RA identified 358 RA-responsive genes. mRNA diversity analysis revealed that 274 genes produced multiple protein-coding transcripts by alternative splicing. Among these 274 genes, we chose 26 genes that showed AS in their C-terminus and 12 transcription factor genes for further analysis. By using transcript-specific primers, we performed quantitative real-time PCR analysis to examine the expression profiles of all the protein-coding transcripts. Consequently, we identified genes which showed different RA-induced changes in the expression of their protein-coding transcripts.
我们使用全反式视黄酸(RA)诱导人 NT2 畸胎瘤细胞向神经元分化,分析了神经元分化后基因的 mRNA 多样性。用 RA 处理的细胞的 DNA 微阵列分析鉴定出 358 个 RA 反应基因。mRNA 多样性分析显示,274 个基因通过选择性剪接产生多个蛋白编码转录本。在这 274 个基因中,我们选择了在 C 端具有 AS 的 26 个基因和 12 个转录因子基因进行进一步分析。通过使用转录物特异性引物,我们进行了定量实时 PCR 分析,以检查所有蛋白编码转录物的表达谱。结果,我们确定了基因,其蛋白编码转录物的表达在 RA 诱导下表现出不同的变化。
