Abstract: The present invention provides a novel composition of matter useful for the treatment of neoplastic diseases. The novel composition is synergistic and comprised of galectin-3C in combination with a proteasome inhibitor, the combination having a pharmacologic activity greater than the expected additive effect of its individual components. Other embodiments of the invention provide novel synergistic compositions of galectin-3C with a proteasome inhibitor capable of reducing or overcoming resistance that develops to the proteasome inhibitor or reducing the adverse side effects from the proteasome inhibitor through increasing the therapeutic efficacy of lower doses.

Abstract: Cancer vaccines were demonstrated to be promising strategies for cancer treatment; however these strategies are limited by the paucity of target antigens that provoke an effective immune response. The Inventors of the present patent application propose that sperm fibrous sheet proteins constitute a new class of potential antigens for use in the development of effective, durable cancer vaccines. This hypothesis is supported by the expression of the sperm fibrous sheath protein, known as Sperm protein 17 (Sp17), which is detected in tumors of unrelated histological origin. It has the ability to induce T-cell based immune responses. The expression of the Sperm protein 17 (Sp17) in tumors of unrelated histological origin, and its' natural localization in the human sperm fibrous sheath (FS), led the Inventors to hypothesize that FS proteins might represent a new potential class of target antigens useful for developing cancer vaccines, as well as diagnostic and therapeutic treatments.

Abstract: The present invention includes a method for the treatment of an advanced ovarian cancer, comprising: identifying a patient with advanced ovarian cancer; and administering to the patient an effective amount of truncated, dominant negative form of Galectin-3 sufficient to reduce the advanced ovarian cancer. In certain aspects, the truncated, dominant negative form of Galectin-3 is provided in an amount sufficient to reduce at least one of growth, motility, invasion, angiogenesis, or prevents Akt/NF-?B activation of the ovarian cancer.
