Overview

Alkylating agents are chemotherapy drugs that damage DNA, killing cancer cells. They can be effective against brain tumors, but some tumor cells develop resistance due to their ability to repair DNA damage. This study focuses on the role of DNA repair mechanisms in resistance to alkylating agents, particularly methylating agents. The study highlights the importance of the enzyme MGMT in repairing methylated DNA damage and its potential as a predictive marker for treatment response. Other DNA repair pathways, such as mismatch repair and homologous recombination, are also discussed. The study explores the potential of targeting DNA repair pathways to overcome resistance and improve treatment outcomes.

Original Abstract of the Article :
Alkylating agents have been used since the 60ties in brain cancer chemotherapy. Their target is the DNA and, although the DNA of normal and cancer cells is damaged unselectively, they exert tumor-specific killing effects because of downregulation of some DNA repair activities in cancer cells. Agents...See full text at original site
