Abstract:
This invention relates to the therapeutic induction of apoptosis in activated inflammatory cells, or cells at a site of inflammation, by introducing into those cells a chimeric gene containing an apoptosis-inducing gene (AIG) driven by a promoter of an inducible gene activated in inflammation and a promoter enhancer such that the inflammatory cells are targeted. In one embodiment, the chimeric gene comprises at least one TNF&agr; promoter enhancer attached to a functional copy of a minimal TNF&agr; promoter and further attached to at least one copy of an apoptosis-inducing gene, wherein expression of the gene is driven by the TNF&agr; promoter. Attachment can be direct, distal, proximal or combinations thereof. Example apoptosis-inducing genes include caspase 3, caspase 4, caspase 5, Granzyme B. Advantageously, the TNFp-AIG chimeric gene is expressed in only those cells producing the inflammatory cytokine, TNF&agr;. In addition, the TNFp-AIG chimeric gene also sequesters inducible TNFp transcription factors, thereby reducing endogenous production of TNF&agr;. The invention also relates to methods of making and using self-regulated apoptosis chimeric genes and pharmaceutical compositions containing them for treating inflammatory diseases.

Abstract:
This invention relates to phosphotyrosine mimics which, when incorporated into an appropriate molecular structure, are capable of inhibiting the binding of tyrosine kinase-dependent regulatory proteins to the native phosphotyrosine-containing receptors. This invention also relates to methods and kits for identifying and using phosphotyrosine mimics. The compounds, kits and methods of this invention are useful for identifying and designing antagonists of tyrosine-kinase dependent regulatory proteins, such as signal transduction proteins containing SH.sub.2 binding domains.

Abstract:
This invention relates to chimeric nucleic acids and to the therapeutic induction of apoptosis in activated inflammatory cells, or cells at a site of inflammation, by introducing into those cells the chimeric nucleic acid. The chimeric nucleic acid having at least one TNF&agr; promoter enhancer attached to a functional copy of a TNF&agr; promoter and further attached to at least one copy of an apoptosis-inducing gene, which is further attached to a 3′UTR. The apoptosis-inducing gene is Granzyme B. The invention also relates to methods of making and using self-regulated apoptosis chimeric nucleic acids and pharmaceutical compositions containing them for treating inflammatory diseases.
