The present invention relates to a double-helix oligonucleotide construct comprising a double-stranded miRNA and a composition for preventing or treating cancer comprising the same. More particularly, the present invention relates to a double-helix oligonucleotide construct comprising miR-544a characterized by a method that effectively inhibits the proliferation of cancer cells or induces a voluntary death of cancer cells, and an anticancer composition comprising the construct.

The invention relates to a double-stranded ribonucleic acid (dsRNA) for inhibiting the expression of a RRM2 gene. The invention also relates to a pharmaceutical composition comprising the dsRNA or nucleic acid molecules or vectors encoding the same together with a pharmaceutically acceptable carrier; methods for treating diseases caused by the expression of a RRM2 gene using said pharmaceutical composition; and methods for inhibiting the expression of RRM2 in a cell.

In certain aspects, provided herein are RNA complexes (e.g., asymmetric RNA complexes, such as asiRNAs or cell penetrating asiRNAs) that inhibit CTGF expression and are therefore useful for treating idiopathic pulmonary fibrosis.

The present invention provides ribosomal RNA origami nanostructures and in particular nanostructures comprising RNA staples, composition comprising such origami nanostructures as well as methods for manufacturing such origami structures.

Compositions and methods for conditionally regulating activities of CRISPR-Cas systems. In some embodiments, the methods comprise providing an inactive guide RNA comprising a regulatory domain bound by a lock nucleic acid different from the guide RNA; and displacing the lock nuclei acid from the regulatory domain by a trigger nucleic acid, thereby activating the guide RNA, wherein the activated guide RNA forms a complex with a Cas enzyme.

The invention relates to double-stranded ribonucleic acid (dsRNA) compositions targeting the ALAS1 gene, and methods of using such dsRNA compositions to alter (e.g., inhibit) expression of ALAS1.

A process is provided of introducing an RNA into a living cell to inhibit gene expression of a target gene in that cell. The process may be practiced ex vivo or in vivo. The RNA has a region with double-stranded structure. Inhibition is sequence-specific in that the nucleotide sequences of the duplex region of the RNA and of a portion of the target gene are identical. The present invention is distinguished from prior art interference in gene expression by antisense or triple-strand methods.

The invention relates to double-stranded ribonucleic acid (dsRNA) compositions targeting the ALAS1 gene, and methods of using such dsRNA compositions to alter (e.g., inhibit) expression of ALAS1.

PVT1 exon 9 is overexpressed in aggressively tumorigenic prostate cancer cell lines and prostate tumor tissues. This exon provides a diagnostic tool for the detection and monitoring of aggressive prostate cancer. Several small interfering ribonucleic acids (siRNAs) are disclosed that are useful for treating prostate cancer.

The invention discloses the use of single-stranded RNA toeholds of different lengths to promote the re-association of various RNA-DNA hybrids, which results in activation of multiple split functionalities inside human cells. Previously designed RNA/DNA nanoparticles employed single-stranded DNA toeholds to initiate re-association. The use of RNA toeholds is advantageous because of the simpler design rules, the shorter toeholds, and the smaller size of the resulting nanoparticles compared to the same hybrid nanoparticles with single-stranded DNA toeholds. Moreover, the co-transcriptional assemblies result in higher yields for hybrid nanoparticles with ssRNA toeholds.
