O8G RNA oxidative modification, also known as 8-oxoguanine oxidation, is a new type of RNA modification. O8G-Seq is another hot spot technology in epitranscriptomics after m6A-Seq. O8G is a kind of RNA modification produced by reactive oxygen species attacking guanine in mRNA in cells, which can pair with adenine and induce guanine-thymine (G>T) mutation. This process is a modification in pathophysiology that leads to disease phenotypes through reactive oxygen species oxidation.
CD Genomics offers O8G RNA oxidation detection by O8G-IP-Seq technology. The technical principle is as follows: Co-incubate O8G-specific antibodies with randomly interrupted RNA fragments, grabbing the O8G-modified fragments for sequencing; A control (Input) sample is sequenced in parallel, and the control sample only contains interrupted RNA fragments and is incubated without O8G-specific antibody. The control sample is used to eliminate the background of non-specifically captured O8G fragments; Compare the sequence fragments of the co-immunoprecipitation (IP) sample with the control sample (Input), locate the O8G oxidation modification site on the transcriptome, and calculate the degree of O8G oxidation in the sample and its RNA expression level according to the RNA-seq data.
CD Genomics not only performs O8G whole-transcriptome sequencing, which can simultaneously detect O8G oxidized circular RNA, lncRNA, mRNA and more, but also detects the O8G oxidation of RNA in mRNA, lnRNA and cricRNA, respectively. With professional bioinformatics analysis platform, we can further provide high-precision O8G oxidation mapping to help customers study the biological functions and potential mechanisms of O8G oxidation. Featured analyses include: identification of O8G RNA oxidation-enriched regions, O8G RNA oxidation region annotation, GO analysis and KEGG signaling pathway analysis of O8G RNA oxidation.
