中文摘要：

人的 Elongator 建筑群显著地类似于它在几个方面的酵母对应物。在以前的研究，我们分析了人的延伸蛋白质的功能 3 (hELP3 ) 由使用的人的 Elongator 的子单元一在里面 vivo 酵母 complementationsystem.However，为在在人的房间调整基因表达的 hELP3 功能的直接证据没被获得。在这研究，我们使用了 hELP3 反感觉寡核苷酸禁止者将 hELP3gene 表示击倒在人的 293T 房间调查它的函数。结果证明 hELP3 mRNA 和蛋白质的那特定的减小引起了 HSP70-2 基因表达的重要抑制，并且这被伴随由嘘一 H3 hypoacetylation 和减少的 RNA 聚合酶 II 在 theHSP70-2 的密度基因。而且，数据也证明 hELP3 施加了 transcriptional 规章在 HSP70-2 基因上通过它的存在直接工作。在这份报告介绍的数据在人的房间在 HSP70-2 基因 transcriptionalelongation 提供进一步的卓见和 hELP3 的函数的直接证据。

英文摘要：

The human Elongator complex is remarkably similar to its yeast counterpart in several aspects. In a previous study, we analyzed the functions of the human elongation protein 3 （hELP3） subunit of the human Elongator by using an in vivo yeast complementation system. However, direct evidence for hELP3 functions in regulating gene expression in human cells was not obtained. In this study, we used hELP3 antisense oligonucleotide inhibitors to knock down hELP3 gene expression to investigate its function in human 293T cells. The results showed that specific reduction of hELP3 mRNA and protein caused a significant suppression of HSP70-2 gene expression, and this was accompanied by histone H3 hypoacetylation and decreased RNA polymerase Ⅱ density at the HSP70-2 gene. Moreover, the data also showed that hELP3 exerted the transcriptional regulatory function directly through its presence on the HSP70-2 gene. Data presented in this report provide further insight and direct evidence of the functions of hELP3 in：HSP70-2 gene transcriptional elongation in human cells.
