title: [Effect of 5-azacytidine on the frequency of polycentric chromosomes in cells with micronuclei during exposure to 5-bromodeoxyuridine].
abstract: Telomeric fusion of metaphase chromosomes was studied in conditions of DNA hypomethylation induced with 5-azacytidine. It was shown that the increased number of dicentric chromosomes was statistically significant in experiments when 5-azacytidine was used together with colcemid and 5-bromodeoxyuridine. These data demonstrate that DNA hypomethylation plays an important role in the manifestation of this phenomenon.
