    Abstract:
    During last three years, the mobile dispersed genetic elements (mdg) were isolated from the genome of Drosophila melanogaster, yeasts and mammals. According to a number of their properties, mdg elements are quite similar to endogenous pro-retroviruses. It is known that in many cases oncogeneity of retroviruses depends on the incorporation of the certain host genes (potential oncogenes) into the viral genome. We suggest that in some cases mdg elements could entrap the potential oncogenes in the course of transposition. As a result, oncogenes become uncontrollable by host regulatory systems and may induce cell transformation. Another possible mechanism underlying switch off of the gene responsible for differentiation control may be mdg transposition to a region in close vicinity of the gene. As transposition of mdg elements seems to occur rather often, they may be regarded as one of the most important factors of genome rearrangements leading to cell transformation.
