摘要:
The present invention provides an expression vector for preventing or inhibiting HlV entry, fusion or replication in mammalian cells. In particular, the invention provides a recombinant retroviral vector that encodes an inhibitor of a HlV co-receptor, such as CCR5 or CXCR4, and a protein that inhibits HIV fusion to target cells and/or HIV replication. Pharmaceutical compositions comprising such constructs and methods of use thereof to prevent or treat HIV infection in a patient are also disclosed.
摘要:
The present invention relates to a polynucleotide vector comprising the Simian taste-bud specific gene (STG) promoter operatively linked to a reporter gene. In preferred embodiments, the STG promoter is the murine ortholog of the STG promoter. In other preferred embodiments, the STG promoter is the human ortholog of the STG promoter. In some preferred embodiments, the reporter gene is green fluorescent protein (GFP). Additionally provided are vectors comprising the STG promoter operatively linked to a cre-recombinase gene.

摘要:
The invention provides a nucleic acid construct comprising a promoter sequence derived from microRNA-21 (miR-21) linked to a nucleic acid sequence encoding an anti-cancer agent, an example of which is a toxin. The constructs of the invention are particularly useful for treating tumors expressing miR-21.
摘要:
Regulatory elements for controlling expression of transgenes in angiogenic tissue are provided. One embodiment provides an isolated nucleic acid having at least 80%, 85%, 90%, 95%, 97%, 99% or 100% sequence identity to SEQ ID NO: I, or a fragment thereof that causes expression of a transgene in angiogenic tissue. Vectors containing SEQ ID NO: 1 and one or more transgenes are also provided. A preferred vector is an adenovirus vector. The transgene can encode a cytotoxin, pro-apoptotic polypeptide, or a therapeutic polypeptide. SEQ ID NO:1 regulates the expression of the transgene such that the transgene is only expressed in angiogenic tissue including, but not limited to arteries feeding ischemic tissues. Methods of using vectors containing SEQ ID NO: 1 are also provided.

摘要:
DNA enhancer sequences are provided for use in constructs to identify early stage embryonic cells. The enhancer sequences can be used in parallel with short-hairpin RNA in a vector construct for endogenously regulated gene knockdowns. The disclosed enhancer sequences can be used to isolate a selected population of early stage embryonic cells.
摘要:
The present invention relates to methods and materials useful for systemically delivering polynucleotides to the spinal cord. Use of the methods and materials is indicated, for example, for treatment of lower motor neuron diseases such as SMA and ALS as well as Pompe disease and lysosomal storage disorders.
摘要:
The present invention relates to viral vectors and in particular to adeno-associated viral vectors with enhanced gene transfer capabilities into cells of the central nervous system (CNS). The invention has been developed primarily for gene transfer in glial cells and further for the treatment of diseases associated with glial cell pathology.
摘要:
Methods, compositions, and therapeutic products for use in the field of oncology and specifically, for the treatment of cancer and other diseases in which SARI is ameliorative or therapeutic and/or small molecule screening for anti-cancer drugs are provided. Cancer specific gene expression using the CCN1 promoter, which is negatively regulated by SARI , for targeting therapeutic molecules in tumors is also provided.
