  • Publication number: 20060029984
    Abstract: In the serum, PSP94 occurs as a free form or is associated with a carrier protein. PSP94 in its bound form has been quantified in the blood of prostate cancer patients and these measurements have shown utility as evaluation or prognosis of prostate cancer. Diagnostic assays, methods, and kits for detecting a free form of PSP94, and reagents such as antibodies able to bind to a free form of PSP94 are disclosed herein.

  • Publication number: 20050147601
    Abstract: Matrix metalloproteinases (MMPs) play an important role in morphogenesis, angiogenesis, wound healing, and in certain disorders such as rheumatoid arthritis, tumor invasion and metastasis. MMPs are thought to be regulated by a variety of cytokines, growth factors, hormones and phorbol esters. This regulation occurs on three levels; alteration of gene expression, activation of the latent zymogen and inhibition by the tissue inhibitors of metalloproteinases (TIMP). We report here a new agent that regulates the level of MMPs.

  • Publication number: 20050096273
    Abstract: Matrix metalloproteinases (MMPs) play an important role in morphogenesis, angiogenesis, wound healing, and in certain disorders such as rheumatoid arthritis, tumor invasion and metastasis. MMPs are thought to be regulated by a variety of cytokines, growth factors, hormones and phorbol esters. This regulation occurs on three levels; alteration of gene expression, activation of the latent zymogen and inhibition by the tissue inhibitors of metalloproteinases (TIMP). We report here a new agent that regulates the level of MMPs in patient. More particularly, members of the PSP94 family, when administered to patients having metastatic hormone resistant prostate cancer, promote a significant decrease in MMP plasma levels. The invention therefore relates to the use of a PSP94 family member for the treatment of a condition related to the activity or expression of MMPs.

  • Publication number: 20050026833
    Abstract: The present invention discloses the use of PSP-94, PCK3145 and other derivatives and biologically active analogues for treating a patient having a condition such as metastasis, metastatic cancer, a condition associated with elevated levels of parathyroid hormone-related protein (PTHrP), PTHrP-induced osteolysis and/or hypercalcemia of malignancy. These compounds were found to be effective treatment modalities for bone metastasis caused by prostate cancer. Furthermore, decrease in cellular and plasma PTHrP levels as well as plasma calcium levels observed by treatment with such compound can serve as useful biochemical markers for monitoring the efficacy of these anti-metastatic compounds.
