Oncogene additivity in the PI3K pathway in cancer

Share

PIK3CA is the most frequently mutated oncogene in cancer and PI3K inhibitors are now a standard treatment in PIK3CA mutant ER+ metastatic breast cancer. In this lecture I will discuss our discovery of double mutant PIK3CA, which functions as a hypermorphic oncogene and results in increased sensitivity to PI3K inhibitors in breast cancer, compared to single mutant PIK3CA. Our studies establish double mutations as a novel mechanism of oncogenesis, leading to a mutational dosage model for the activation and inhibition of oncogenic PI3K. Further dissection of this model will yield new mechanistic insights to broaden the scope of PI3K inhibitors in cancer.
