Abstract: A method for suppressing or inhibiting the growth of a cancer cell or tumor cell that expresses one or more integrins on its cell surface in a subject in need thereof is disclosed, herein, the method comprising administering to the subject an effective amount of contortrostatin (CN) and/or vicrostatin (VCN) or an equivalent of each thereof and wherein the CN and/or VCN or the equivalent of each thereof is conjugated to a therapeutic radioisotope.

Abstract: A method of treating ovarian cancer (OC) includes administering to a subject in need thereof an effective amount of a pharmaceutical composition comprising vicrostatin and/or a protein substantially similar to vicrostatin. The administration is preferably performed intraperitoneally. The methods may include concurrently or sequentially administering to the patient one or more additional treatments for ovarian cancer. A pharmaceutical composition used in connection with the methods of the present invention comprise vicrostatin loaded in a viscoelastic gel comprising polyethylene oxide (PEO) and carboxymethyl cellulose (CMC).

Abstract: Provided herein are methods for expressing proteins with disulfide bridges such as Vicrostatin (VCN), a chimeric variant of native snake venom disintegrin Contortrostatin (CN). The methods include what is believed to be a more efficient natural selection process that results in generating increased amounts of correctly-folded active conformers of proteins with disulfide bridges. In an aspect, this is achieved by growing Origami B cells in a more optimal redox environment during the induction of heterologous recombinant protein production.

Abstract: Provided herein are compositions and methods for treating soft tissue injuries using a patch having a polymer on its surface linked to polypeptides having a disintegrin domain. The polypeptides having a disintegrin domain can include contortrostatin, vicrostatin, and ADAM derived polypeptides. Compositions of the invention can be used for the treatment of injuries to soft tissues that include the eye, liver and brain.
