[Fluorescence in situ hybridization in studying the human genome].

Physical chromosome mapping by fluorescence in situ hybridization (FISH) is among the major lines of research on the human genome (as well as genomes of numerous other organisms). To localize particular genes or anonymous DNA sequences on individual chromosomes or chromosome regions, FISH was developed in the late 1980s and early 1990s, when the International Human Genome Project and the Russian program Human Genome were launched. Now FISH continues to play a prominent part in studies of the human genome. The review considers the major steps of FISH development in Russia with special emphasis on the key roles of the Institute of Cytology and Genetics (Novosibirsk) and Engelhardt Institute of Molecular Biology (Moscow). Physical mapping of human chromosomes 3 and 13 by FISH is described in detail. The promotion of FISH in Russia contributed to the progress in the related fields such as comparative animal genomics (ZOO-FISH) and studies of plant chromosomes.
