Radiation Resistance in Lipovirus-Altered Human Cells.
Human cells altered by infection with the "lipovirus," a transmissible cytopathic agent, are highly resistant to ionizing radiation. Whereas about 500 roentgens will inhibit cell multiplication in normal cells, more than 500,000 roentgens are required to produce a similar effect in the altered cells. This gross change in cellular radiosensitivity may provide a useful system for studying in vitro the mechanisms of inhibition of cell division by radiation.
