Abstract: The present disclosure describes methods of treating lymphoma that expresses a short histone H2A variant. In some embodiments, the method can comprise collecting a sample from a subject having or suspected of having lymphoma, detecting a short histone H2A variant (sH2A) expression level in the sample collected from the subject, and administering to the subject a therapeutically effective dose of an anthracycline agent, if the subject has sH2A variant expression level that is detectable. In other embodiments, the sH2A is the H2A.B variant. In other embodiments, the anthracycline agent can be aclarubicin.

Abstract: DUX4 can be used as a biomarker for predicting a patient's response to immunotherapy, and inhibition of DUX4 can be used in therapeutic methods for treating DUX4+ cancers. Accordingly, aspects of the disclosure relate to a method for treating cancer in a patient comprising administering a DUX4 inhibitor to the patient. Further aspects of the disclosure relate to a method for treating a DUX4+ cancer in a patient, the method comprising administering a checkpoint inhibitor to the patient. Other aspects relate to a composition comprising a DUX4 inhibitor and a checkpoint inhibitor.
