摘要:
The present invention provides methods for preventing or treating a fibrotic disease in a subject. In some embodiments, the fibrotic disease is fatty liver disease, non-alcoholic fatty liver disease, or non-alcoholic steatohepatitis. In particular aspects, the methods comprise administering an inhibitor of Shc gene expression to achieve genetic suppression of Shc activity in the subject. In other aspects, the methods comprise administering a peptide, peptoid, or peptide-peptoid hybrid inhibitor of Shc to achieve pharmacological suppression of Shc protein activity in the subject.
摘要:
This invention relates to polynucleotides comprising a nucleotide sequence encoding a PPT1 polypeptide or a fragment thereof, vectors (viral or non-viral vectors) comprising the same, and methods of using the same for delivery of the open reading frame to a cell or a subject and to treat infantile neuronal lipofuscinosis (infantile Batten disease). The polynucleotides comprise an optimized CLN1 open reading frame.
摘要:
One embodiment is directed to a system for altering the function of a sensory unit that innervates a targeted tissue region in an animal, the sensory unit being configured to express a light-responsive protein, comprising a light delivery element configured to direct radiation to at least a portion of a targeted tissue structure; and a light source configured to provide light to the light delivery element; wherein the targeted tissue structure is illuminated transcutaneously with radiation such that a membrane potential of cells comprising the targeted tissue structure is modulated at least in part due to exposure of the light-responsive protein to the radiation.
摘要:
mRNAs containing an exogenous open reading frame (ORF) flanked by a 5' untranslated region (UTR) and a 3' UTR is provided, wherein the 5' and 3' UTRs are derived from a naturally abundant mRNA in a tissue. Also provided are methods for identifying the 5' and 3' UTRs, and methods for making and using the mRNAs.
摘要:
The invention provides genetic constructs and recombinant vectors comprising such constructs. The constructs and vectors can be used in gene therapy methods for treating a range of disorders, including glaucoma and deafness, or for promoting nerve regeneration and/or survival.
摘要:
The invention provides models of various conditions including but not limited to intestinal inflammation and/or fibrosis, inflammatory bowel disease, colitis, acute colitis, and chronic colitis, and methods of using such models for designing, screening and developing therapeutics for those conditions. The invention also provides methods, compositions, and kits for treating those conditions.
摘要:
Disclosed herein, are compositions and methods for the treatment of human immunodeficiency virus infection. The compositions comprise engineered transcription activator like effector nucleases (TALENs) comprising a TALE DNA binding domain flanked by two spacer sequences, and a Fokl nuclease catalytic domain. Also, described herein, are methods of using TALENs to cleave nucleic acids; and methods of administering the TALENs to subjects at risk for or having an HIV infection.
摘要:
The present invention relates generally to the field of RNA Control Devices and/or destabilizing elements (DE) combined with Chimeric Antigen Receptors (CARs) in eukaryotic cells. The present invention also relates to split CARs (Side-CARs) in eukaryotic cells. More specifically, the present invention relates to DEs, RNA Control Devices, and/or side-CARs combined with Chimeric Antigen Receptors to make small molecule actuatable CAR polypeptides. The present invention also relates to DE-CARs, Smart CARs (Smart = small molecule actuatable RNA trigger), Smart-DE-CARs, and/or Side-CARs for use in the treatment of disease.
摘要:
The present invention relates to nucleic acid expression cassettes and vectors containing liver- specific regulatory elements and codon-optimized factor IX or factor VIII transgenes, methods employing these expression cassettes and vectors and uses thereof. The present invention is particularly useful for applications using liver-directed gene therapy, in particular for the treatment of hemophilia A and B.
摘要:
The invention provides a platform and methods of using the platform for the regulation of the expression of a target gene using exposure to an aptamer ligand (for example, a small molecule). The platform features a polynucleotide gene regulation cassette that is placed in the target gene and includes a synthetic riboswitch positioned in the context of a 5' intron-alternative exon-3' intron. The riboswitch comprises an effector region and a sensor region (e.g., an aptamer that binds a small molecule ligand) such that the alternative exon is spliced into the target gene mRNA when the ligand is not present thereby preventing expression of the target gene. When the ligand is present, the alternative exon is not spliced into the target gene mRNA thereby providing expression of the target gene.
