Abstract
We have studied the lethality produced in pBR322 DNA after PUVA treatment (8-MOP+UVA). As recipients, we used a collection of E. coli strains differing in their repair capacities and analysed the involvement of several DNA repair pathways in the removal of plasmid lesions. We have also studied the effect of UVA radiation alone, in order to determine more precisely the effect attributable only to psoralen molecules. Results showed a strong lethal effect derived from PUVA treatment; however, some plasmid recovery was achieved in bacterial hosts proficient in Excision repair and SOS repair. Another repair pathway, only detectable at high density of lesions, appeared to be relevant for the removal of 8-MOP:DNA adducts.(Author) 11 refs.
