Recombination activating gene of mammalian origin (RAG-1), cDNA of RAG-1 of mammalian origin, mRNA expressed by RAG-1, the encoded recombinase and antibodies specific for the recombinase, as well as the use of the same for a diagnostic or therapeutic purpose.
Abstract:
The present invention relates to methods for producing transgenic animals using retroviral constructs engineered to carry a transgene(s) of interest.
Abstract:
The present disclosure relates to regulation of functions of hematopoietic stem cells (HSCs) by delivering of miRNAs, including miR-125b, miR-126, and miR-155, to HSCs. For example, in some embodiments, blood output in a mammal can be increased by administering miR-125b, miR-126, and/or miR-155 oligonucleotides. Also disclosed are methods for promoting hematopoietic stem cell engraftment and method for treating a myeloproliferative disorder.
Abstract:
Methods and compositions are provided for delivering a polynucleotide encoding a gene of interest to a target cell using a virus. The virus envelope comprises a cell-specific binding determinant that recognizes and binds to a component on the target cell surface, leading to endocytosis of the virus. A separate fusogenic molecule is also present on the envelope and facilitates delivery of the polynucleotide across the membrane and into the cytosol of the target cell. The methods and related compositions can be used for treating patients having suffering from a wide range of conditions, including infection, such as HIV; cancers, such as non-Hodgkin's lymphoma and breast cancer; and hematological disorders, such as severe combined immunodeficiency.
Abstract:
Methods and compositions are provided for delivery of a polynucleotide encoding a gene of interest, typically an antigen, to a dendritic cell (DC). The virus envelope comprises a DC-SIGN specific targeting molecule. The methods and related compositions can be used to treat patients suffering from a wide range of conditions, including infection, such as HIV/AIDS, and various types of cancers.
Abstract:
The invention provides methods and compositions for the expression of small RNA molecules within a cell using a lentiviral vector. The methods can be used to express doubles stranded RNA complexes. Small interfering RNA (siRNA) can be expressed using the methods of the invention within a cell, which are capable of down regulating the expression of a target gene through RNA interference. A variety of cells can be treated according to the methods of the invention including embryos, embryogenic stem cells, allowing for the generation of transgenic animals or animals constituted partly by the transduced cells that have a specific gene or a group of genes down regulated.
Abstract:
A system and method for analyzing a biological substance, the device comprising: a specimen input device; at least one pumping device in flow communication with a chemical reservoir and said specimen input device; and at least one flow cell in flow communication with said at least one pumping device via at least one flow valve, wherein said at least one flow cell is configured to contain said specimen and includes a sensing device configured to sense at least one characteristic of said specimen.

Abstract:
Sam68 plays a role in TNF-dependent signaling, including NF-kB signaling and extrinsic activation of apoptosis. In some embodiments, inhibitors of Sam68 are administered to inhibit TNF-dependent signaling, for example to inhibit NF-kB signaling or apoptosis in a patient in need. In some embodiments, functional Sam68 is administered to increase TNF-dependent signaling, for example to induce apoptosis in a patient in need. In some embodiments, methods are provided determining whether the TNF-dependent or TNF-independent branch of a signaling pathway is active in a cell or cells, or for drug screening applications.
Abstract:
The present disclosure relates to the finding that microRNA-155 plays a role in the development and activity of CD4+ T cells. CD4+ T cell development and function, particularly TH17 and TH1 T cell development, can be modulated by delivery of microRNA-155 (miR-155) or antisense miR-155 to target CD4+ cells or precursor cells. In some embodiments, antisense miR-155 is used to reduce tissue specific autoimmune inflalmmation and to treat autoimmune disease. In addition, miR155 and antisense miR-155 can be used to modulate expression of cytokines from dendritic cells.
