Described herein are mutations that confer resistance to treatment with a BTK inhibitor. Described herein are modified BTK polypeptides that exhibit decreased inhibition (i.e. are resistant) to a covalent and/or irreversible BTK inhibitor. Also described herein modifications of PLCy2 and CARD 11 polypeptides that confer resistance to treatment with a BTK inhibitor. Described herein are diagnostic methods for detecting the modified polypeptides and nucleic acids encoding the modified polypeptides and applications of the methods thereof. Described herein are compositions, combinations, and kits containing the modified polypeptides and methods of using the modified polypeptides. Also described herein are methods of using modified BTK polypeptides as screening agents for the identification and design of second-generation BTK inhibitors.

Mutations associated with resistance to inhibitors of Bruton's Tyrosine Kinase (BTK)

The invention relates to methods of treating cancer, with a combination of an arginase inhibitor and a chemotherapeutic agent. The invention further relates to methods of assessing efficacy of a cancer treatment by measuring arginine levels in a tumor.

Compositions and methods for inhibiting arginase activity

The invention relates to methods of treating cancer, myeloproliferative diseases, or immunological or neurological diseases with a combination of a glutaminase inhibitor and an anticancer agent such as an enzyme inhibitor (such as a kinase inhibitor), a mitotic inhibitor, a DNA-modifying agent, or a cytidine analog. The invention further relates to methods of treating cancer, myeloproliferative diseases, or immunological or neurological diseases that are resistant to one or more anticancer agents.
