Phosphatidylinositol phosphate kinase type 1 gamma splice variants as biomarkers and drug targets for epithelial cancers

摘要

The present invention relates generally to the field of phosphatidylinositol based signaling pathways, and more specifically to the use of novel members of these pathways for disease prognosis and treatment. In some aspects, the present invention relates to the use of novel splice variants of type I phosphatidylinositol phosphate kinase γ, named PIPKIγ 700 and PIPKIγ 707, to determine breast cancer and breast cancer prognosis.
