  • Publication number: 20220356452
    Abstract: The present invention relates to an indirect three-dimensional co-culture. The indirect co-culture may comprise bone marrow niche cells, tumor cells and a culture medium. The bone marrow niche cells and the tumor cells may be incubated in the culture medium without direct contact between the bone marrow niche cells and the tumor cells. The tumor cells may be dormant or reactivated. Also provided are a method for preparing the indirect co-culture and a method for screening for an agent capable of inhibiting reactivation of dormant tumor cells or promoting dormancy of proliferating tumor cells.

  • Patent number: 8450374
    Abstract: Disclosed herein are novel antagonists of the androgen receptor and androgen receptor mutations associated with clinical failure of currently prescribed anti-androgens and use of said antagonists in the treatment of conditions associated with inappropriate activation of the androgen receptor.
    Type: Grant

  • Patent number: 6596534
    Abstract: A therapeutic agent based on a recombinant adenovirus which employs an osteocalcin promoter for the expression of thymidine kinase can be administered intravascularly to treat metastatic cancer, including osteosarcoma, breast cancer, prostate cancer, ocular melanoma or brain cancer. Systemic administration of this agent provides a preferred route over previous disclosure of local direct administration. The same therapeutic agent can be effectively employed in the treatment of benign conditions, including benign prostatic hypertrophy and arteriosclerosis.
    Type: Grant
    Filed: March 23, 2000
    Date of Patent: July 22, 2003
    Assignee: The University of Virginia Patent Foundation
    Inventors: Leland W. K. Chung, Chinghai Kao, Robert A. Sikes, Song-Chu Ko, Jun Cheon
  • Publication number: 20020155119
    Abstract: The invention comprises methods for identifying biomarkers useful for prognostic or diagnostic assays of human prostate disease, and for identifying those fetal genes which are differentially expressed between prostate cancers versus normal or benign prostate.

  • Patent number: 5772993
    Abstract: A recombinant adenovirus Ad-OC-TK was constructed, with cell specific gene expression, which contains osteocalcin (OC) promoter that drives the expression of herpes simplex virus thymidine kinase (TK); the addition of acyclovir (ACV), a pro-drug for the inhibition of cell proliferation, to Ad-OC-TK resulted in the induction of osteoblast-specific cell death in vitro. The Ad-OC-TK virus plus ACV treatment is highly selective in blocking the growth of both murine and human osteosarcoma cell lines in vitro and murine osteosarcoma in vivo.
