The compositions and methods of the invention provide compositions and methods for preferential targeting of tissues to delivery therapeutic or diagnostic agents. For example, such compounds are useful in the treatment of joint disorders those affecting articulating joints, e.g., injury-induced osteoarthritis as well as autoimmune diseases affecting joint tissue such as rheumatoid arthritis.

The present invention provides RNAi agents, e.g., double stranded RNAi agents, that target the transthyretin (TTR) gene and methods of using such RNAi agents for treating or preventing TTR-associated diseases.

The current invention provides a method of activating fibroblast and myofibroblast apoptosis in a tissue of a mammal, comprising administering to the tissue a therapeutically effective amount of a composition comprising an siRNA molecule that binds to an mRNA that codes for TGFB1 protein in a mammalian cell, an siRNA molecule that binds to an mRNA that codes for COX-2 protein in a mammalian cell, and a pharmaceutically acceptable carrier comprising a pharmaceutically acceptable histidine-lysine polymer. The invention also provides additional methods for using this composition.

The present invention provides compositions comprising therapeutic nucleic acids such as siRNA that target ApoC3 and ANGPTL3 expression, lipid particles comprising one or more (e.g., a combination) of the therapeutic nucleic acids, and methods of delivering and/or administering the lipid particles (e.g., for treating hypertriglyceridemia in humans).

Provided are gRNA that can direct a Cas enzyme to target a CTGF gene and the use thereof, which belongs to the technical field of gene editing. The gRNA may direct the Cas enzyme to perform targeted cleavage on an SMAD binding site region of a CTGF gene promoter, or the gRNA may direct the Cas enzyme to perform targeted cleavage on a CTGF gene exon 2 region. The gRNA can reduce the overexpression of the human CTGF gene via a CRISPR-Cas gene editing system. The above-mentioned gRNA is used for preparing a drug for use against fibrotic diseases.

The present invention relates to a small activating nucleic acid molecules and uses thereof for treating diseases and conditions, such as thrombocytopenia, related to THPO protein deficiency or insufficiency. As described herein, small activating nucleic acid molecules can be double-stranded or single-stranded RNA molecules targeting the promoter region of the Thpo/THPO gene through an RNA activation mechanism and comprise a first nucleic acid strand and a second nucleic acid strand. The double-stranded RNA molecule targeting the promoter region of the Thpo/THPO gene comprises two nucleic acid strands of 16 to 35 nucleotides in length, wherein one nucleic acid strand has at least 75% homology or complementarity to a target selected from the promoter region of the Thpo/THPO gene. The present invention also relates to pharmaceutical compositions and formulations comprising the small activating nucleic acid molecules and methods for up-regulating the expression of the Thpo/THPO gene in a cell and treating diseases and conditions, related to THPO protein deficiency or insufficiency, by administering small activating nucleic acid molecules, pharmaceutical compositions, and formulations thereof.

The present disclosure relates to compositions of oligonucleotide (e.g., SMAD7 antisense oligonucleotide diastereomers) and methods of manufacturing, assessing efficacy, and using the compositions.

The present invention relates to a product comprising (i) an anti-VEGF entity; and (ii) a negative complement regulator, or nucleotide sequences encoding therefor, as a combined preparation for simultaneous, separate or sequential use in therapy. In particular, the anti-VEGF entity is an anti-VEGF antibody, preferably aflibercept and the negative complement regulator is Complement Factor I (CFI) or Complement Factor H Like Protein 1 (FHL1). The main uses are for the treatment of eye diseases, in particular age-related macular degeneration (AMD).

Provided is a double stranded RNA (dsRNA) compound comprising a guide strand and a passenger strand, the guide strand and the passenger strand each having a length of at least 300 basepairs (bp), the guide strand comprising a segment complementary to a target nucleic acid sequence of a target gene transcript. Also provided are methods of silencing a target gene transcript in a vertebrate cell or subject, of treating a pathogen infection in a subject, and of reducing replication or infectivity of a pathogen infection in the vertebrate cell or subject, respectively, comprising administering to the subject or cell a dsRNA compound, vector, conjugate or composition herein disclosed.
