DNA damage enhancement

DNA damage enhancement" refers to a **therapeutic principle or process** rather than a specific molecular target. The goal is to increase the amount or frequency of DNA damage within cells, commonly to potentiate the effects of anti-cancer therapies or to weaken tumor cells' ability to repair their genome, thereby driving them toward cell death. Approaches for DNA damage enhancement include the use of DNA-damaging chemotherapy or radiation, as well as **inhibition of endogenous DNA repair pathways** (such as with PARP, ATR, or ATM inhibitors), thereby escalating genomic instability in cancer cells beyond a survivable threshold. While effective in cancer therapy, this strategy is **not a receptor or molecule itself** and thus does not have aliases, a molecular classification, or a canonical abbreviation. It also raises notable **safety concerns** due to potential collateral damage to healthy dividing cells and induction of genomic instability.

Induction of DNA strand breaks (single or double); Inhibition of DNA repair pathways (e.g., PARP, ATR/Chk1, ATM/Chk2, DNA-PK); Overcoming cell cycle checkpoints to force cells with unrepaired DNA into mitosis (mitotic catastrophe)
