Fluorescent light induces malignant transformation in mouse embryo cell cultures.

Fluorescent light induced a dose-dependent malignant transformation in mouse C3H10T1/2 cells. A plateau in the dose-response curve for transformation was correlated with that observed with ultraviolet light exposure. The similarity in the two dose-response patterns suggests that similar molecular processes may be involved in the induction of malignant transformation by the two types of radiation.
