  • Patent number: 11866476
    Abstract: Provided herein are cytokines or functional fragments thereof that, in some embodiments, are engineered to be masked by a masking moiety at one or more receptor binding site(s) of the cytokine or functional fragment thereof. In some embodiments, the cytokines are engineered to be activatable by a protease at a target site, such as in a tumor microenvironment, by including a proteolytically cleavable linker. In some embodiments, the proteolytically cleavable linker links the cytokine to the masking moiety, links the cytokine to a half-life extension domain, and/or links the masking moiety to a half-life extension domain. The masking moiety blocks, occludes, inhibits (e.g., decreases) or otherwise prevents (e.g., masks) the activity or binding of the cytokine to its cognate receptor or protein. Upon proteolytic cleavage of the cleavable linker at the target site, the cytokine becomes activated, which renders it capable of binding to its cognate receptor or protein with increased affinity.

  • Patent number: 7556796
    Abstract: A method of producing a tumorigenic mouse cell, the tumorigenicity of which depends on a recombinant gene of interest is disclosed. The method involves: (a) providing a conditionally tumorigenic mouse cell containing a recombinant oncogene operably linked to an inducible promoter, wherein (i) expression of the recombinant oncogene is necessary and sufficient for the tumorigenicity of the tumorigenic mouse cell, and (ii) the inducible promoter is in the uninduced state; and (b) introducing into the cell a recombinant gene of interest that functionally complements the oncogene, thereby restoring tumorigenicity without expression of the inducible recombinant oncogene. Also disclosed is a method of testing a compound for anti-tumor effects.

  • Patent number: 7544476
    Abstract: The disclosure provides a method for identifying cancer tissue sensitive to treatment with an inhibitor of Notch receptor activation. The method comprises determining the level of HeyL gene expression in a sample derived from the cancer tissue, wherein an elevated level of HeyL gene expression alone in the sample indicates sensitivity to the cancer tissue to treatment with an inhibitor of Notch receptor activation.
