Fragmentation shows a persistent bias with regard to the cleavage rates of various dinucleotides. With the exception of CpG dinucleotides the previously described biases were consistent with results of the DNA cleavage in solution. Here we computed cleavage rates of all dinucleotides including the methylated CpG and unmethylated CpG dinucleotides using data of the Whole Genome Sequencing datasets of the 1000 Genomes project. We found that the cleavage rate of CpG is significantly higher for the methylated CpG dinucleotides. Using this information, we developed a classifier for distinguishing cancer and healthy tissues based on their CpG islands statuses of the fragmentation. A simple Support Vector Machine classifier based on this algorithm shows an accuracy of 84%. The proposed method allows the detection of epigenetic markers purely based on mechanochemical DNA fragmentation, which can be detected by a simple analysis of the NGS sequencing data."}],"department":[{"_id":"FyKo"}],"day":"25","type":"journal_article","file":[{"relation":"main_file","checksum":"099e51611a5b7ca04244d03b2faddf33","content_type":"application/pdf","file_name":"2020_ScientificReports_Uroshlev.pdf","creator":"dernst","access_level":"open_access","date_updated":"2020-07-14T12:48:05Z","file_id":"7947","date_created":"2020-06-08T06:27:32Z","file_size":1001724}],"date_updated":"2023-08-21T07:00:17Z","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"month":"05","article_processing_charge":"No","status":"public","title":"A method for identification of the methylation level of CpG islands from NGS data","quality_controlled":"1","date_created":"2020-06-07T22:00:51Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","oa_version":"Published Version","oa":1,"scopus_import":"1","publisher":"Springer Nature","article_type":"original","citation":{"ama":"Uroshlev LA, Abdullaev ET, Umarova IR, et al.
