[Radiation mapping as one of main methods of creating high resolution maps of human and animal genomes].
Radiation hybrid mapping (RH mapping) is considered as one of the main methods of constructing physical maps of mammalian genomes. In introduction, theoretical prerequisites of developing of the RH mapping and statistical methods of data analysis are discussed. Comparative characteristics of universal commercial panels of the radiation hybrid somatic cells (RH panels) are shown. In experimental part of the work, RH mapping is used to localise nucleotide sequences adjacent to NotI sites of human chromosome 3 with the aim to integrate contig map of NotI clones to comprehensive maps of human genome. Five nucleotide sequences adjacent to the sites of integration of papilloma virus in human genome and expressed in the cells of cervical cancer were localised. It was demonstrated that the region 13q14.3-q21.1 was enriched with nucleotide sequences involved in the processes of oncogenesis. RH mapping can be considered as one of the most perspective applications of the modern radiation biology in the field of molecular genetics, that is, in constructing physical maps of mammalian genomes with high resolution level.
