New models of drug-resistant breast cancer hint at better treatments

Breast cancer that spreads to other organs is extremely difficult to treat. Doctors can buy patients time, but a cure remains elusive. Now, researchers at the School of Medicine have shown that human breast tumors transplanted into mice are excellent models of metastatic cancer and could be valuable tools in the search for better treatments. Shown are human breast cancer cells (red) growing amid mouse cells (green).

Breast cancer expert Matthew Ellis, MD, PhD, works with the Genome Institute at Washington University to sequence entire breast cancer genomes — the billions of “letters” making up a person’s DNA. The goal is to unlock the mysteries of breast cancer and tailor treatments to individual patients.
