Abstract
We have isolated cDNA sequences from TPA‐treated primary human fibroblasts, which indicate RNA species that are coordinately regulated after treatment of these cells with either ultraviolet light, mitomycin C, the UV‐induced factor EPIF, or TPA. The levels of RNA are elevated in Bloom syndrome (cells of two out of three patients). After transformation with SV40 one of the sequences is overexpressed while another one is reduced. Both genes maintain their inducibility by the agents mentioned.
