    摘要: Vectors, such as retroviral vectors and transposon-based nonviral vectors, are disclosed herein that can be used to target transgene expression to the proliferating periosteal cells and cells in the marrow space after bone fracture. In one embodiment, these vectors include a human Cox-2 gene that is modified to improve mRNA stability and protein translation by truncating the 3′ untranslated region (UTR). In addition, in some embodiments, the native translation signal is replaced with an optimized Kozak sequence. These vectors can be used alone or with vectors expressing BMP2/4, FGF-2, or LMP-1 gene to repair bone fractures and increase prostaglandin secretion. Methods for identifying agents that accelerate bone repair are also disclosed.

    摘要: The present invention features compositions and methods for the inducible expression of a polypeptide, especially a polypeptide normally cytotoxic to the eukaryotic host cell in which it is to be expressed. A nucleotide sequence encoding a polypeptide of interest is operably linked to an inducible promoter. Expression from the inducible promoter is regulated by a multi-chimeric transactivating factor, composed of a first ligand-binding domain that negatively regulates transcription, a transcriptional activation domain, and a second ligand-binding domain that positively regulates the transcriptional activation function of the transactivator. Transcription of the nucleotide sequence under control of the inducible promoter is activated by the multi-chimeric transactivator when both the ligand that binds the first ligand-binding domain is absent and the ligand that binds the second ligand-binding domain is present. This inducible expression system is particularly useful in the expression of the cytotoxic protein VSV G for the production of pseudotyped retroviral vectors.

    摘要: The present invention features compositions and methods for the inducible expression of a polypeptide, especially a polypeptide normally cytotoxic to the eukaryotic host cell in which it is to be expressed. A nucleotide sequence encoding a polypeptide of interest is operably linked to an inducible promoter (e.g, a promoter composed of a minimal promoter linked to multiple copies of tetO, the binding site for the tetracycline repressor (tetR) of the Escherichia coli tetracycline resistance operon Tn10). Expression from the inducible promoter is regulated by a multi-chimeric transactivating factor, composed of a first ligand-binding domain that negatively regulates transcription (e.g., a prokaryotic tetracycline repressor polypeptide), a transcriptional activation domain, and a second ligand-binding domain that positively regulates the transcriptional activation function of the transactivator (e.g., a ligand-binding domain of a steroid receptor, preferably an estrogen receptor (ER)). Transcription of the nucleotide sequence under control of the inducible promoter is activated by the multi-chimeric transactivator when both the ligand that binds the first ligand-binding domain (e.g., tetracycline) is absent and the ligand that binds the second ligand-binding domain (e.g., a steroid) is present. This inducible expression system is particularly useful in the expression of the cytotoxic protein VSV G for the production of pseudotyped retroviral vectors.

    摘要: The present invention features packaging cell lines and recombinant retroviral particles produced thereby, particularly pseudotyped retroviral particles. Preferably, the packaging cell lines are derived from HeLa, Cf2Th, D17, MDCK, or BHK cells, most preferably from Cf2Th cells. Retroviral particles are produced by inducibly expressing an envelope protein of interest (e.g., a retroviral envelope or the envelope protein of vesicular stomatitis virus (VSV G)). Inducible expression of the envelope protein is accomplished by operably linking an envelope protein-encoding nucleotide sequence to an inducible promoter (e.g., a promoter composed of a minimal promoter linked to multiple copies of tetO, the binding site for the tetracycline repressor (tetR) of the Escherichia coli, tetracycline resistance operon Tn10). Expression from the inducible promoter is regulated by a multi-chimeric transactivating factor, composed of a first ligand-binding domain that negatively regulates transcription from the inducible promoter (e.g., a prokaryotic tetracycline repressor polypeptide (tetR)), a transcriptional activation domain, and a second ligand-binding domain (e.g., a ligand-binding domain of a steroid receptor, preferably an estrogen receptor (ER)).
