title: [Transposition of chromosome loci in bystander cells upon exposure to an adaptive dose of ionizing radiation].
abstract: During the process of the realization of the bystander effect the trans of the Signal from irradiated cells to the intact cell (bystander cells) happens. So both type of cells (irradiated and intact cells) have the same damages and reactions. There are new data about bystander effect as the transduction mechanism of the adaptive response and we have investigated this phenomenon. There are an incubation of the intact (bystander cells) and the exposed (X-radiation of 10 cGy) human lymphocytes and we analyze the location of the centromeric loci of the first chromosome. We observed hat for the first time that after X-ray exposition of the adaptive doses the transposition of the chromosome loci from the peripheral to the central parts of the nucleus in intact (bystander cell) G0-lymphocytes which were incubated in the growth environment cells with irradiated cells removal. We support that the starting states of the adaptive response is the loci extrication of the matrix, the transposition and the approach homologous chromosomes. This process is necessary for the DNA double strand breaks reparation (in the case of injured dose X-radiation) with the participation of the homologous recombination.
