METHODS AND COMPOSITIONS FOR PREDICTING RESISTANCE TO ANTICANCER TREATMENT WITH PROTEIN KINASE INHIBITORS

摘要

The instant application provides methods and related compositions pertaining to the identification of resistance to anticancer treatment in a patient. In a particular embodiment, the invention provides biomarkers for the identification of resistance to anticancer treatment in a lung cancer patient, wherein a reduced expression of a MEDIATOR and/or SW1/SNF complex gene in the lung cancer cells of the patient indicates that the lung cancer cells in the patient may be resistant to treatment with a receptor tyrosine kinase inhibitor, such as gefitinib and/or erlotinib. In some embodiments, the invention relates to methods and related compositions for predicting resistance to anticancer treatment by detecting the expression levels of one or more TGF-beta pathway nucleic acids and/or proteins.
