Methods for obtaining structural data from RNA in a sample, and RNA probes for performing the same, are provided. Methods of reversibly modifying RNA is a sample, in vitro or in vivo, and reversible probes for performing the same, are provided. The RNA probes may be SHAPE probes that include aryl or heteroaryl acyl imidazoles. The RNA probes may be reversible probes that include an aryl or heteroaryl ring substituted with a hydroxyl-reactive group and an azido-containing group. Also provided are methods of comparing in vitro and in vivo RNA structural data. Also provided are methods of diagnosing a cellular proliferative disease condition, e.g., by probing HOTAIR RNA. Aspects of the invention further include compositions, e.g., probes and kits, etc., that find use in methods of the invention.
本发明提供了从RNA样品中获取结构数据的方法以及执行相同操作的RNA探针。本发明还提供了可逆修饰RNA的方法,包括体外或体内修饰RNA的方法,以及执行相同操作的可逆探针。RNA探针可以是包括芳基或杂环芳基酰基咪唑的SHAPE探针。RNA探针可以是包括芳基或杂环芳基环并含有羟基反应基团和含有叠氮基团的可逆探针。本发明还提供了比较体外和体内RNA结构数据的方法。本发明还提供了诊断细胞增生性疾病状态的方法,例如通过探测HOTAIR RNA。本发明的方面还包括在本发明方法中使用的组合物,例如探针和试剂盒等。
