  • Publication number: 20130101513
    Abstract: The present invention describes methods of identifying, detecting, imaging, isolating and locating cancer cells in a subject. The method invokes the use of near-infrared (NIR) organic carbocyanine dyes, particularly, near infrared heptamethine cyanine dyes and the detection of the fluorescence of these NIR dyes. The uptake of these dyes by cancer cells and not by normal cells, as well as their high intensity, among other things, allow for the detection of cancerous cells in a subject and facilitate their subsequent isolation. Further, detection of many tumor types and tumor cell populations under cell culture and in vivo conditions are described.

  • Publication number: 20100015148
    Abstract: A method for interfering with osteomimetic properties of a cell includes introducing into the cell an osteomimecry-interfering compound, wherein said osteomimecry-interfering compound prevents or ameliorates the expression of the osteomimetic properties of said cell. A method for treating or ameliorating an osteotropic-related cancer or disorder in a subject includes administering to the subject an osteomimecry interfering compound. A method for identifying a compound that modulates the osteomimetic potential of a cell includes contacting a cell exhibiting osteomimetic potential with a test compound; measuring expression levels of one or more osteomimetic gene products in the cell in the presence and in the absence of the test compound; and identifying a compound that modulates the osteomimetic potential, wherein the compound changes the expression levels of one or more osteomimetic gene products in the cell.

  • Publication number: 20070015149
    Abstract: The compositions and methods of the present invention are based, in part, on a gene designated prostate leucine zipper (PrLZ) and the sequences that mediate its expression. The presence of the leucine zipper indicates that PrLZ encodes a protein that interacts with other proteins. Methods to inhibit the activity of PrLZ by identifying and inhibiting the interaction between PrLZ and such binding partners are within the scope of the invention, as are methods of inhibiting PrLZ in other ways (by, for example, inhibiting its expression with antisense molecules or siRNAs or inhibiting its activity with, for example, anti-PrLZ antibodies). Such inhibition is useful in the treatment of cancers or dysplasias affecting PrLZ-positive tissues, such as those in the prostate.

  • Publication number: 20040101840
    Abstract: The present invention relates to the isolation, cloning, and characterization of a prostate-specific PC-1 gene differentially expressed by prostate cells and tissues. The present invention additionally relates to replication-competent adenovirus vectors which are specific for cells which allow a PC-1 transcriptional regulatory sequence to function, such as prostate cancer cells, prostate stromal cells, breast cancer cells, renal cells, bladder cells, and cells of the endometrium, and methods of use of such viruses are provided. These viruses comprise an adenoviral gene under control of a PC-1 transcriptional regulatory sequence. Such replication-competent adenovirus vectors are useful in the treatment of prostate cancer, brain cancer, ovarian cancer, thyroid cancer, tumors, renal carcinoma, bladder cancer, lung cancer, or breast cancer.

  • 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.

  • Publication number: 20030078224
    Abstract: The present invention provides methods and compositions for the delivery and expression of therapeutic genes for treating prostate and non-prostate tumors in a gene therapy setting with therapeutic genes driven by a super PSA promoter. This approach enhances the capability of increasing the size of therapeutic gene inserts and maintaining specificity and efficiency of genes expression. This form of gene therapy strategy can be applied either alone or in combination with other adjuvant therapies or used in combination with various gene therapy strategies to achieve the maximum effect in cancer treatment, and in normal and benign tissues to enhance therapeutic gains.
