Title: Polymeric Carrier for Delivery of Small Interfering RNA

Patent Number: 7,740,880

Filed: March 3, 2006

Lead Inventor: Won Jong Kim, University of Utah

"A carrier for delivering small interfering RNA into cells includes a cholesterol residue covalently bonded to oligoarginine," the patent's abstract states. "Mixing the siRNA with the carrier produces a complex-containing composition … [while] contacting a cell with the complex-containing composition results in delivery of the siRNA into the cell. Delivery of an siRNA targeted to vascular endothelial growth factor is a treatment for cancer. Methods of making the carrier and complex are also disclosed."

Filed: Aug. 16, 2005

Lead Inventor: Elena Feinstein, Quark Pharmaceuticals (Silence Therapeutics)

The invention, the patent's abstract states, "provides novel molecules, compositions, methods, and uses for treating microvascular disorders, eye diseases, and respiratory conditions based upon inhibition of the RTP801 gene and/or protein."


Title: Regulation of Oncogenes by microRNAs

Patent Number: 7,741,306

Filed: Dec. 4, 2009

Lead Inventor: Phillip Frost, Opko Health

The invention, the patent application's abstract states, comprises "siRNA compositions and methods useful for inhibiting expression of vascular endothelial growth factor isoforms. Such compositions and methods further involve siRNA capable of selectively targeting angiogenic VEGF isoforms while selectively sparing anti-angiogenic isoforms. Diseases which involve angiogenesis stimulated by over-expression of VEGF, such as diabetic retinopathy, age-related macular degeneration, and many types of cancer, can be treated by administering small interfering RNAs."


Title: siRNA Targeting BCL2L1

Application Number: 20100152064

Filed: Jan. 15, 2010

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."


Title: RNA Interference-Mediated Inhibition of Cyclic Nucleotide Type 4 Phosphodiesterase Gene Expression Using Short Interfering Nucleic Acid

Application Number: 20100152278

Filed: May 2, 2008 PCT Filed: May 2, 2008

Lead Inventor: Vasant Jadhav, Sirna Therapeutics (Merck)

The invention, the patent application's abstract states, "relates to compounds, compositions, and methods for the study, diagnosis, and treatment of traits, diseases, and conditions that respond to the modulation of cyclic nucleotide type 4 phosphodiesterase gene expression and/or activity, including PDE4B1, PDE4B2, and PDE4B3 gene expression and/or activity. The … invention is also directed to compounds, compositions, and methods relating to traits, diseases, and conditions that respond to the modulation of expression and/or activity of genes involved in cyclic nucleotide type 4 phosphodiesterase gene expression pathways or other cellular processes that mediate the maintenance or development of such traits, diseases, and conditions, including but not limited to IL-6, IL-1, IL-8, IL-15, TNF-alpha, and matrix metalloproteinases such as MMP-1, MMP -2, MMP-3, MMP-9, and MMP-12.

"Specifically, the invention relates to double-stranded nucleic acid molecules including small nucleic acid molecules … capable of mediating RNA interference against cyclic nucleotide type 4 phosphodiesterase gene expression, including cocktails of such small nucleic acid molecules and lipid nanoparticle formulations of such small nucleic acid molecules," the abstract adds. The invention also relates to "small nucleic acid molecules … that can inhibit the function of endogenous RNA molecules or RNAi pathway components … or that can inhibit the function of RISC to modulate PDE4B gene expression. ... Such small nucleic acid molecules are useful, for example, in providing compositions to prevent, inhibit, or reduce inflammatory, respiratory, and autoimmune diseases, traits, and conditions, and/or other disease states associated with PDE4B gene expression or activity in a subject or organism."

Application Number: 20100152282

Filed: Jan. 29, 2008 PCT Filed: Jan. 29, 2008

Lead Inventor: Patrick Arbuthnot, University of Witwatersrand

The invention, the patent application's abstract states, comprises a "DNA polynucleotide … having a modified sequence of a target gene, wherein any one type of nucleotide in the target gene sequence has been chemically modified to another type of nucleotide; and a complementary sequence of the unmodified target gene, wherein either one of the modified sequence or the complementary sequence is in a reverse orientation to the other sequence … and the RNA sequence transcribed from the DNA polynucleotide forms a duplex between the modified sequence and the complementary sequence so that a long double-stranded RNA duplex forms between the modified and complementary sequences with base pair mismatches where the nucleotides have been modified."

The duplex, it adds, is capable of "inhibiting expression of the target gene. RNA polynucleotides and … duplexes transcribed by the DNA polynucleotide are also described, as is a method for producing the … duplexes," which can be used in gene silencing.
