T. Ortiz et al., T4 DNA-LIGASE REDUCES CHROMOSOME-DAMAGE AND ENHANCES CELL-SURVIVAL INCHO CELLS TREATED WITH BLEOMYCIN, Cytogenetics and cell genetics, 78(3-4), 1997, pp. 197-201
The effect of DNA ligase from T4 phage on the modulation of the damage
induced by bleomycin was studied. CHO6 cells were electroporated with
either bleomycin alone or bleomycin plus T4 DNA ligase, and both cyto
genetic and clonogenic assays were carried out in parallel. Our result
s show that T4 DNA ligase is able to decrease the frequency of chromos
ome aberrations in bleomycin-treated cells while increasing cell survi
val.
