Abstract: Methods for treating a subject with cancer, including administering to the subject an effective amount of an inhibitor of DNAse1L3 and an effective amount of radiation therapy are provided. In some examples, the methods involve enhancing or inducing response of tumor-associated immune cells in the subject, including administering to the subject an effective amount of radiation therapy, and administering to the subject an effective amount of an inhibitor of DNAse1L3, thereby enhancing or inducing the response of tumor-associated immune cells in the subject. In some examples, the tumor-associated immune cells comprise dendritic cells or macrophages.

Abstract: The present invention features compositions and methods for enhancing an anti-tumor response by administering an OX40 agonist (e.g., an anti-OX40 antibody) and/or an anti-CTLA4 antibody (e.g., a CTLA4-blocking antibody) in combination with a cancer therapy.

Abstract: Disclosed herein are methods of treating or inhibiting a pre-malignant condition, a benign neoplasia, or a virally-induced growth in a subject. The methods include administering a composition including an effective amount of one or more Stimulator of Interferon Genes (STING) agonists, or a pharmaceutically acceptable salt or prodrug thereof, to the subject. In particular embodiments, the methods include administering one or more STING agonists that are a cyclic dinucleotide or a derivative thereof to the subject, for example cyclic diadenylate monophosphate, cyclic diguanylate monophosphate, or a derivative thereof.
