    Breast cancer new development for HER2+

    New Nanoparticles to Stop Growth of HER2-Positive Breast Cancer

    HER2 (human epidermal growth factor receptor 2) is a protein that is associated with some particularly aggressive forms of breast cancer. The presence of high concentrations of this protein seems to lead to the growth of tumors, so inactivating HER2 may help to stop the spread of certain strains of cancer in the body.

    An existing technique involves introducing an antibody that can block HER2 from binding to other things, but now researchers at Nanjing University in China have developed a polymer nanoparticle that can bind to HER2 just as well as antibodies. These nanoparticles can halt the normal functionality of HER2 and reduce the number of new tumor cells that sprout. Their advantage is that, unlike antibodies, they’re cheap to manufacture, easy to handle, and can be kept chemically stable.
