  The present invention relates to high-throughput methods comprising direct infusion electrospray ionization mass spectrometry (ESI-MS), multistep tandem mass spectrometry (MSn), consecutive reaction monitoring (CRM), ion mobility spectrometry mass spectrometry (IMS-MS), high-resolution MS, and IMS-MS, for genome-wide (whole cell or tissue) profiling of DNA and RNA nucleotides/nucleosides having a wide variety of variant structural modifications. In particular, these methods are contemplated for providing a specific profile of variant DNA and/or RNA chemically modified nucleic acids (i.e. structures) associated with specific medical conditions. Medical conditions may include, but are not limited to: cancer; including prostate, lung, uterus, larynx, ovary, breast, kidney, and many other types of cancers; specific stages of cancer; bacterial infections; viral infections; genetic and metabolic disorders; and any condition involving changes in DNA and/or RNA structural modifications.

  本发明涉及高通量方法，包括直接注入电喷雾离子化质谱（ESI-MS）、多步串联质谱（MSn）、连续反应监测（CRM）、离子迁移谱质谱（IMS-MS）、高分辨率 MS 和 IMS-MS，用于对具有多种变异结构修饰的 DNA 和 RNA 核苷酸/核苷进行全基因组（全细胞或组织）分析。特别是，这些方法可用于提供与特定病症相关的变异 DNA 和/或 RNA 化学修饰核酸（即结构）的特定概况。病症可包括但不限于：癌症；包括前列腺癌、肺癌、子宫癌、喉癌、卵巢癌、乳腺癌、肾癌和许多其他类型的癌症；癌症的特定阶段；细菌感染；病毒感染；遗传和代谢紊乱；以及任何涉及 DNA 和/或 RNA 结构修饰变化的病症。
