  • Patent number: 8507646
    Abstract: The present application features methods and compositions for treating patients suffering from atherosclerosis or at risk for developing atherosclerosis. The treatment includes administering to the patient a pharmaceutical composition that includes an agent capable of blocking the interaction between uPA and its receptor uPAR, e.g., an ATF or a fragment thereof, an anti-uPA antibody, a uPAR or a fragment thereof, or an antibody that specifically binds to uPAR.

  • Publication number: 20100234274
    Abstract: The present invention provides a method of treating diabetes by increasing peripheral nesfatin-1. Peripheral nesfatin-1 can be increased by administration of nesfatin-1, conjugated nesfatin-1 that would not penetrate the blood-brain barrier, or plasmin inhibitors. The present invention also provides a method of screening for an agent that would increase peripheral or brain nesfatin-1.

  • Publication number: 20090226410
    Abstract: It has now been discovered that certain mutant forms of pro-urokinase (“pro-UK”), such as so-called pro-UK mutant “M5” (Lys.sup.300.fwdarw.His)-, perform in the manner of pro-UK in lysing “bad” blood clots (those clots that occlude blood vessels), while sparing hemostatic fibrin in the so-called “good” blood clots (those clots that seal wounds, e.g., after surgery or other tissue injury). Thus, these pro-UK mutants are excellent and safe thrombolytic agents. These advantages allow them to be used in a variety of new methods, devices, and compositions useful for thrombolysis and treating various cardiovascular disorders in clinical situations where administration of other known thrombolytic agents has been too risky or even contraindicated.

  • Patent number: 5472692
    Abstract: The invention relates to thrombolytically active pro-urokinase (pro-UK) mutants comprising the amino acid sequence of native pro-UK, but including a mutation which causes the pro-UK mutants to induce less fibrinogenolysis and non-specific plasminogen activation than native pro-UK, to have at least a 10-fold lower intrinsic activity than native pro-UK, and to have substantially the same fibrin promotion and thrombolytic activity after plasmin activation compared to native pro-UK when administered to a patient.
