Abstract: Embodiments of the disclosure concern the use of expression constructs in which at least one polyA signal is embedded upstream of an expressible transcript, such as within a 5? UTR for the transcript, for example. In certain embodiments, the polyA signal is comprised within a ligand-binding aptamer, and the binding of the ligand to the aptamer, or lack thereof, dictates the outcome for the expressible transcript. In specific embodiments, absence of the ligand causes the expressed transcript having a polyA in its 5? UTR to be expressed but then degraded, whereas presence of the ligand causes inhibition of degradation upon expression of the expressible transcript. More than one ligand-binding aptamer may be present on the same expression construct.

Abstract: Embodiments of the disclosure include methods and compositions in which two inter-chromosomal or intra-chromosomal genomic DNA regions are rearranged upon exposure of the genomic DNA to a chimeric RNA that produces fusion of the two regions. The chimeric RNA hybridizes to the two different parts of the genomic DNA and forms a DNA/RNA hybrid in a sequence-specific manner, thereby facilitating genomic rearrangement. In particular embodiments this mechanism is utilized to produce directed gene fusion in targeted genomic DNA regions.

Abstract: Embodiments of the disclosure include compositions and methods for generating RNA nanostructures, particularly in a cell. In particular embodiments, RNA subunits comprising at least one three-way junction and at least one kissing loop are configured such that multiple RNA subunits can polymerize into a specific structure. In particular embodiments, the RNA subunits are configured such that sequence of at least one kissing loop is complementary to sequence of another kissing loop, such as on another RNA subunit, and the summation of multiple RNA subunits having specific individual structures results in a combined polymerized structure of a defined shape. In specific embodiments, an RNA nanostructure generated from methods herein is utilized for an application, such as manufacturing or genetic modifications in a cell.
