Abstract: Nucleic acid molecules configured to specifically express a sequence of interest in a cancer cell, comprising: a transcription factor binding region comprising 3-10 repeats of a transcription factor binding site, a minimal promoter and the sequence of interest operatively linked to the transcription factor binding region and minimal promoter, wherein the transcription factor is selected from SOX9, GATA10, TCF7L1, LEF1, MYBL2 and MYB are provided. Nucleic acid molecule systems and compositions comprising the nucleic acid molecules are also provided as are methods of treating cancer.

Abstract: The present disclosure describes compositions and methods for selection functional aptamers. In certain embodiments, provided herein are methods of using aptamer cluster-containing particles to identify functional aptamers from an aptamer library. In certain embodiments, provided herein are functionally enriched populations of aptamers. In certain embodiments, provided herein are methods for selecting an aptamer for use in personalized cancer treatment and methods for preparing a tumor delivery system. In certain embodiments, provide herein are compositions comprise the aptamer cluster-containing particles, target cells (e.g., cancer cells, immune cells, etc.) and/or a detectable indicator of cellular function (e.g., a fluorescent indicator of apoptosis, cell proliferation, gene or protein expression, etc.).

Abstract: Provided herein are bispecific personalized aptamers that induce the cell death of cancer cells and methods of use thereof.

Abstract: Provided herein are aptamers that target cytotoxic T-lymphocyte and methods of use thereof.
