PIK3CA H1047R KNOCK-IN NON-HUMAN ANIMAL BREAST CANCER MODEL

摘要

The invention concerns the development of a PIK3CA H1047R knock-in non-human animal breast cancer model, and its use for identification of a spontaneous loss-of-function TP53 mutation involved in spindle cell tumor formation. The invention further concerns the identification of additional somatic mutations and copy number aberrations in the breast tumors using this model, and methods and means for the diagnosis and treatment of breast cancer.
