“Combined application of BCNU and Res caused more apoptosis in 5-FU sensitive cells in comparison to individual treatment.”
“Fifty percent cell death were noted in parental cells when 18 μmol/L of Res was associated with fixed concentration (20 μmol/L) of BCNU , but a much lower concentration of Res (8 μmol/L) was needed to achieve the same effect in 5-FU resistant cells.”
“In addition, the combined application of BCNU and Res caused a significant decrease of major DNA base excision repair components in 5-FU sensitive cells.”
“Increased genotoxicity and apoptosis were observed in resistant cells after combined application of BCNU and Res in comparison to untreated or parental cells.”
