Title: Nucleic Acid Compounds for Inhibiting VEGF Family Gene Expression and Uses Thereof

Application Number: 20100047909

Filed: Feb. 28, 2008 PCT Filed: Feb. 28, 2008

Lead Inventor: Steven Quay, MDRNA

The invention, the patent application's abstract states, comprises "meroduplex ribonucleic acid molecules capable of decreasing or silencing one or more VEGF family gene expression. An mdRNA of this disclosure comprises at least three strands that combine to form at least two non-overlapping double-stranded regions separated by a nick or gap wherein one strand is complementary to one or more VEGF family mRNA. In addition, the meroduplex may have at least one uridine substituted with a 5-methyluridine and optionally other modifications or combinations thereof. Also provided are methods of decreasing expression of one or more VEGF family gene in a cell or in a subject to treat one or more VEGF family-related disease."


Title: siRNA Targeting Tumor Protein 53

Application Number: 20100048425

Filed: Sept. 18, 2009

Lead Inventor: Anastasia Khvorova, Dharmacon (Thermo Fisher Scientific)

"Efficient sequence-specific gene silencing is possible through the use of siRNA technology," the patent application's abstract states. "By selecting particular siRNAs by rational design, one can maximize the generation of an effective gene-silencing reagent, as well as methods for silencing genes. Methods, compositions, and kits generated through rational design of siRNAs are disclosed."

Title: Role of miRNA in T Cell Leukemia

Application Number: 20100048674

Filed: June 8, 2009

Lead Inventor: Chang-Zheng Chen, Stanford University

"The ability of miR-181a to support active signaling between Notch and pre-TCR pathways by coordinately dampening negative regulators of these pathways allows the use of miR-181a as a therapeutic target for T-ALL," the patent application's abstract states.


Title: miRNA Triplex Formations for the Down-Regulation of Viral Replication

Application Number: 20100048675

Filed: July 30, 2009

Inventor: Omar Bagasra, Claflin University

"As discovered herein, using miRNAs having high homology with both HIV-1 and a co-infecting virus such as HHV-6, HHV-7, or GVB-C, one can inhibit viral replication, more particularly HIV-1 replication, using such mutually homologous miRNAs that give rise to the creation of stable triplex formations effective in the down-regulation and/or inhibition of viral replication," the patent application's abstract states.
