01

Overview

Tumor site-specific DNA damage refers to the targeted induction or exploitation of DNA lesions within tumor cells, leveraging their unique vulnerabilities in DNA repair pathways. This concept is central to many cancer therapies that aim to selectively kill cancer cells by overwhelming their compromised ability to repair genetic damage, while sparing normal tissues.

02

Mechanism of action

Induction of DNA lesions (strand breaks, crosslinks); inhibition of DNA repair pathways; exploitation of synthetic lethality
