Radiation-Enhanced Survival of a Human Virus in Normal and Malignant Rat Cells

Journal Article · · Experimental Biology and Medicine
The repair phenomena of host-cell reactivation (HCR), uv reactivation (UVR) and X-ray reactivation (X-ray R) were studied in normal embryonic (OMRE) and malignant (RMT) rat cells of the same strain by examining the survival of uvirradiated herpes simplex virus (HV-1). Experiments indicated that HCR was present to the same extent in both OMRE and RMT cells as evidenced by similar e-1 values for both components of the virus survival curve as well as similar extrapolation numbers for the resistant component. UVR and X-ray R were demonstrated in RMT cells as indicated by enhanced survival of irradiated virus; however, both of these repair processes were absent in OMRE cells. The amount of UVR in RMT cells increased with virus uv dose and cell uv exposure. Finally, t was evident that HCR and radiation enhanced reactivation (UVR and X-ray R) may operate independently in these mammalian virus–host cell systems.
