复旦大学Ting Ni研究团队揭示人类癌症中内含子多聚腺苷酸化的状况和临床意义。相关论文于2024年5月11日在线发表在《遗传学报》上。

研究人员应用IPAFinder对癌症基因组图谱(TCGA)项目中涵盖所有33种癌症类型的10383个样本中的,内含子多腺苷酸化(IPA)事件进行了鉴定和量化。研究人员一共识别出21835个IPA事件,其中近一半是泛在表达的。研究人员在不同癌症类型中发现了2761个独特的动态变化IPA事件。此外,研究人员还观察到8855个与临床相关的非冗余IPA事件,这些事件有可能被用作预后指标。
 
这些分析还揭示了癌症信号通路中动态IPA的使用可能会影响药物反应。最后,研究人员开发了一个用户友好型数据门户网站IPACancer Atlas (http://www.tingni-lab.com/Pancan_IPA/),用于搜索和探索癌症中的IPA。
 
据了解,IPA是一种RNA 3'端加工过程,据报道在癌症的发生发展中起着重要作用。然而,目前还缺乏对各种癌症类型中IPA事件的全面了解。

Abstract: Intronic polyadenylation (IPA) is an RNA 3' end processing event which has been reported to play important roles in cancer development. However, the comprehensive landscape of IPA events across various cancer types is lacking. Here, we apply IPAFinder to identify and quantify IPA events in 10,383 samples covering all 33 cancer types from The Cancer Genome Atlas (TCGA) project. We totally identify 21,835 IPA events, almost half of which are ubiquitously expressed. We identify 2,761 unique dynamically changed IPA events across cancer types. Furthermore, we observe 8,855 non-redundant clinically relevant IPA events, which could potentially be used as prognostic indicators. Our analysis also reveals that dynamic IPA usage within cancer signaling pathways may affect drug response. Finally, we develop a user-friendly data portal, IPACancer Atlas (http://www.tingni-lab.com/Pancan_IPA/), to search and explore IPAs in cancer.
