TI - Circulating DNA-markers in lung cancer: changes in retrotrasposons methylation status in response therapy and during the post-treatment follow-up KW - онкомаркеры KW - рак легкого KW - циркулирующая опухолевая ДНК KW - метилирование KW - статьи в сборниках N1 - Библиогр.: 4 назв N2 - Malignant cell transformation is accompanied by two processes of DNA methylation changes: hypermethylation in CpG islands of tumor suppressor genes and global hypomethylation in repetitive DNA sequences (retrotransposons) [1, 2]. The composition of circulating DNA (cirDNA) from plasma and cell-surface-bound cirDNA (csb-cirDNA) was shown earlier to be altered in the blood of cancer patients due to accumulation of tumor-specific aberrantly methylated DNA fragments, which are currently considered valuable cancer markers [3, 4] UR - http://vital.lib.tsu.ru/vital/access/manager/Repository/vtls:000662058 ER -
