DESCRIPTION (provided by applicant): When a gene is activated, it is copied ("transcribed") from DNA into a string of molecules called a messenger RNA (mRNA). The middle section of each mRNA encodes the information that is translated into the corresponding protein sequence; the two ends, called untranslated regions (UTRs), play a number of other important roles. This proposal concerns the tail end of the mRNA, known as the 3' UTR, which helps to regulate the stability and location of the mRNA and the amount of the corresponding protein that is produced. The point at which the transcription of a given mRNA ends is determined by the presence of a sequence called a polyadenylation site. Some genes have more than one such site, meaning that there can be two or more different forms of the corresponding mRNA, with different 3' UTRs and therefore different levels of activity. Changes in the ratio of the different forms are thought to contribute to the development of a range of disorders, including some cancers. The methods currently used to study polyadenylation require an extra set of experiments to be run, which is expensive and slow. However, Drs. Birol and Karsan and their teams have obtained evidence that polyadenylation can be studied alongside other important types of transcriptional regulation, using data from experiments that are already performed as part of standard analysis. This will make studies of polyadenylation sites affordable by more laboratories, and will add value to existing data.

描述（由申请人提供）：当基因被激活时，它会从 DNA 复制（“转录”）成一串称为信使 RNA (mRNA) 的分子。每个mRNA的中间部分编码翻译成相应蛋白质序列的信息；两端称为非翻译区 (UTR)，发挥着许多其他重要作用。该提案涉及 mRNA 的尾端，即 3' UTR，它有助于调节 mRNA 的稳定性和位置以及产生的相应蛋白质的量。给定 mRNA 转录的结束点由称为聚腺苷酸化位点的序列的存在决定。有些基因具有多个这样的位点，这意味着可能存在两种或多种不同形式的相应 mRNA，具有不同的 3' UTR，因此具有不同的活性水平。不同比例的变化 人们认为这些形式会导致一系列疾病的发生，包括一些癌症。目前用于研究聚腺苷酸化的方法需要进行一组额外的实验，这是昂贵且缓慢的。然而，博士。 Birol 和 Karsan 及其团队已经获得证据，表明多腺苷酸化可以与其他重要类型的转录调控一起研究，使用已经作为标准分析一部分进行的实验数据。这将使更多的实验室能够负担得起对聚腺苷酸化位点的研究，并将增加现有数据的价值。
