氧化的RNA损伤与RNA功能的丧失和许多人类年龄相关疾病的发生有关。因此,需要在全基因组的基础上确定和量化RNA氧化程度的方法。我们将含有8-羟基鸟嘌呤的mRNA的亲和筛选与高通量DNA测序相结合,发展了一种新的方法。我们证明,这种检测方法适用于检测RNA转录本之间氧化程度的差异。我们将这种方法应用于在生理条件下生长的酿酒酵母对过氧化氢的响应,并检测到显著氧化的RNA转录本。
Oxidative RNA damage has been linked to loss of RNA function and to the development of many human age-related diseases. Consequently, a need exists for methods to identify and quantify the extent of RNA oxidation on a genome-wide basis. We developed such a method by combining affinity selection of mRNA containing 8-hydroxyguanine with high throughput DNA sequencing. We demonstrate that this assay is suitable for detecting differences in the extent of oxidation between RNA transcripts. We applied this method to the yeast Saccharomyces cerevisiae grown under physiological conditions and in response to hydrogen peroxide, and detected significantly oxidized RNA transcripts.
