Finding a Needle in a Haystack: Identifying Tumor Suppressors

Head & Neck squamous cell carcinoma and triple negative breast cancer is the leading cause of death due to cancer in men and women. Advances in genome sequencing technology are helping clinicians to identify the hundreds of somatic mutations accumulated in patient’s tumor cells. However, not all of them are driver mutations responsible for cancer progression and metastasis. Most of those somatic mutations in genes are mere bystanders. Only the driver genes cause cancer, while the bystander genes do not cause cancer. Finding the driver genes among the hundreds of other mutations in a patient tumor is like finding a needle in a haystack.

Using our lab’s novel in utero technique in mouse models of cancer, we investigate hundreds of genes simultaneously to find out the real driver genes. Once these driver genes are identified, they can be studied further and targeted specifically to improve the cancer treatment.
