Abstract: Provided herein are, inter alia, methods useful for delivering nucleic acids and kinase inhibitors to a cell. The methods provided herein include the delivery of therapeutic nucleic acids to cancer cells by contacting a cancer cell with a kinase inhibitor and a therapeutic nucleic acid. The methods provided herein are therefore, inter alia, useful for the treatment of cancer.

Abstract: A composition of phosphodiester oligonucleotides of various defined sizes has been created that mimics the effects of defibrotide. The composition essentially consists of mixtures of synthetic phosphodiester oligonucleotides comprising Nmers ranging from 40 mers to 65 mers. The phosphodiester oligonucleotides are preferably heteropolymers composed of either A, G, C, and T at each position but may also be homopolymers, i.e. the same base may be present at each position in the oligonucicotidc. These mixtures are effective in the treatment of cancer and other diseases.
