Treating cancers by targeting faulty DNA repair

Targeting DNA Repair for Cancer Therapy.

NIH-funded research Yale University · NIH-11261736

What this research studies

This work studies how certain tumors overproduce metabolites (2HG, fumarate, succinate) that impair a key DNA-repair pathway and create a specific weakness. The team uses laboratory experiments, unbiased CRISPR genetic screens, and small-molecule drug screens to identify the chromatin and end-protection factors involved and to find drugs that exploit these defects. They are also probing how tumors become resistant to PARP inhibitors and testing strategies to overcome resistance. Prior findings from this group have already supported early clinical trials that apply these ideas to patients with relevant tumor mutations.

Who could benefit from this research

Good fit: People with cancers known to overproduce oncometabolites—such as tumors with IDH1/2, fumarate hydratase (FH), or succinate dehydrogenase (SDH) mutations—would be the most relevant candidates for these approaches or related trials.

Not a fit: Patients whose tumors lack these oncometabolite-driven DNA repair defects are unlikely to benefit from these specific strategies.

Why it matters

Potential benefit: If successful, this research could produce targeted therapies that improve outcomes for patients whose tumors carry IDH1/2, FH, or SDH mutations by exploiting DNA repair defects.

How similar studies have performed: Prior laboratory work from this group and several early clinical trials have shown promising responses to PARP inhibitors in tumors with these oncometabolite-related DNA repair defects.
