How cells repair dangerous DNA breaks using homologous recombination

Molecular mechanisms of DNA double strand break repair by homologous recombination

NIH-funded research Dana-Farber Cancer Inst · NIH-11262319

This project aims to understand how cells fix severe DNA breaks using a precise repair process, with the goal of helping people whose cancers are linked to DNA-repair problems such as some breast and ovarian cancers.

What this research studies

You will be hearing about work that breaks down, step by step, how cells mend the most dangerous kind of DNA damage, double-strand breaks, using the homologous recombination pathway. The team will study how broken DNA ends are processed into single-stranded tails, how the RAD51 protein finds matching DNA and forms invasion structures (D-loops), and how new DNA is copied and rejoined. Researchers will use purified proteins and laboratory reconstitutions that recreate these molecular events so they can watch and measure each step. The goal is to reveal detailed mechanisms that could point to new therapeutic targets for cancers caused by defective DNA repair.

Who could benefit from this research

Good fit: People with breast or ovarian cancers linked to inherited or acquired defects in homologous recombination (for example BRCA1/2-related tumors) would be most relevant to the findings of this work.

Not a fit: Patients whose cancers are unrelated to DNA repair defects or people with non-cancer conditions are unlikely to see direct benefit from this specific project.

Why it matters

Potential benefit: If successful, this work could reveal new drug targets or strategies that improve treatments for cancers driven by defective DNA repair, such as some breast and ovarian cancers.

How similar studies have performed: Previous genetic and biochemical studies of homologous recombination have clarified key steps and helped lead to therapies like PARP inhibitors, but detailed reconstitutions of the entire mechanism remain an active and advancing area of research.
