Radioresistance induced by oncogenic transformation

Radiat Res. 1989 Nov;120(2):267-79.


Rat embryo cells at various stages of oncogenic transformation are obtained by a combination of X irradiation and transfection with the ras and the myc oncogenes. Transfection with either the ras or the myc oncogenes can lead to increased radioresistance, relative to the parental cells. X-ray-transformed clones of the transfected cells do not show additional alteration in radioresponse. Incorporation of the two oncogenes appears to lead to a higher degree of radioresistance.
