PREDICTIVE MARKER OF DNMT1 INHIBITOR THERAPEUTIC EFFICACY AND METHODS OF USING THE MARKER

摘要

Provided herein are methods for predicting efficacy of a DNA (cytosine-5)methyltransferase1 (DNMT 1) inhibitor treatment in a subject having a cancer, methods of identifying a subject having a cancer that is more likely to respond to a DNMTI inhibitor treatment, and methods of selecting a treatment for a subject having a cancer that include determining a level of SOX9 in a sample containing cells from a subject having a cancer. Also provided are methods of treating a subject having a cancer that include selectively administering a DNMTI inhibitor to a subject having cancer determined to have an elevated level of SOX9 in cells from the subject compared to a reference level. Also provided are antibodies and antigen-binding antibody fragments that specifically bind to SOX9, and nucleic acid sequences that contain at least 10 nucleotides complementary to a contiguous sequence present in a SOX9 nucleic acid for use in these methods.
