Researchers develop new antibody against breast cancers

Researchers at Cold Spring Harbour Laboratory have developed an antibody that can inhibit an enzyme called PTPRD, which is overexpressed in some breast tumors. The antibody binds to two PTPRD molecules and draws them together into an inactive configuration, preventing the enzyme from working and leading to its destruction. This has shown promising results in reducing the invasiveness of breast cancer cells in the lab, indicating that the antibody could be a potential therapeutic treatment for certain breast tumors.
