The present invention concerns methods and compositions for forming anti-cancer vaccine DNL complexes using dock-and-lock technology. In preferred embodiments, the anti-cancer vaccine DNL complex comprises an antibody moiety that binds to dendritic cells, such as an anti-CD74 antibody or antigen-binding fragment thereof, attached to an AD (anchoring domain) moiety and a xenoantigen, such as CD20, attached to a DDD (dimerization and docking domain) moiety, wherein two copies of the DDD moiety form a dimer that binds to the AD moiety, resulting in the formation of the DNL complex. The anti-cancer vaccine DNL complex is capable of inducing an immune response against xenoantigen expressing cancer cells, such as CD138negCD20+ MM stem cells, and inducing apoptosis of and inhibiting the growth of or eliminating the cancer cells.

Immunogenic compositions, cancer vaccines and methods for treating cancer are provided. Compositions comprising: (a) a glycan such as Globo H or an immunogenic fragment thereof, wherein the glycan is conjugated with a carrier protein by a linker such as para-nitrophenyl; and (b) an adjuvant comprising glycolipid capable of binding CD1d on a dendritic cell, such as an α-galactosyl-ceramide derivative, wherein the immunogenic composition induces an immune response that induces a higher relative level of IgG isotype antibodies as compared to IgM isotype antibodies, are provided. Immunogenic compositions comprising the carrier protein diphtheria toxin cross-reacting material 197 (DT-CRM197) and the adjuvant C34 are provided. Antibodies generated by immunogenic compositions disclosed herein further neutralize at least one of the antigens Globo H, stage-specific embryonic antigen-3 (SSEA-3) and stage-specific embryonic antigen-4 (SSEA-4). Therapeutics against breast cancer stem cells comprising immunogenic compositions comprising Globo H, SSEA-3 or SSEA-4 conjugated with DT-CRM197.

An isolated binding partner of a Cripto-1 protein, Pim-1 protein or an antigen present in a colon cancer cell lysate is described. The binding partner inhibits growth of one or more cancer cell types and may be used in an anti-cancer agent for treating cancer in a subject. The binding partner may also be used in a method of inducing apoptosis in a cancer cell, as well as in a method of sensitizing a cancer cell to a cytotoxic compound. In addition, a cancer vaccine is described wherein the vaccine comprises a Cripto-1 protein (or an antigenic fragment thereof), Pim-1 protein (or an antigenic fragment thereof) or an antigen present in a colon cancer cell lysate or, alternatively, comprises an expressible DNA molecule encoding a Cripto-1 protein (or an antigenic fragment thereof), Pim-1 protein (or an antigenic fragment thereof) or an antigen present in a colon cancer cell lysate.

Compositions for the diagnosis and therapy of prostate and colon cancer, derived from or based on a novel prostate-specific, androgen-related, cell membrane associated and secreted serine protease termed 20P1F12 / TMPRSS2 are described. A full length cDNA comprising the entire coding sequence of the 20P1F12 / TMPRSS2 gene (also designated 20P1F12-GTC1 herein) is provided (FIG. 1). Among the compositions provided are antibodies that bind to 20P1F12 / TMPRSS2 proteins and polypeptide fragments thereof, including antibodies labeled with a detectable marker or toxin or therapeutic composition. The invention also provides prognostic and diagnostic methods of examining a biological sample for evidence of disregulated cellular growth by comparing the status of 20P1F12 / TMPRSS2 in the biological sample to the status of 20P1F12 / TMPRSS2 in a corresponding normal sample, wherein alterations in the status of 20P1F12 / TMPRSS2 in the biological sample are associated with disregulated cellular growth. The invention further provides various therapeutic compositions and strategies for treating prostate cancer, including particularly, 20P1F12 / TMPRSS2 polypeptide and anti-20P1F12 / TMPRSS2 antibody therapy methods and compositions, cancer vaccines, and small molecule therapy.

Cancer antigen peptides derived from WT1 which have an in vivo efficacy, particularly a clinical usefulness, and cancer vaccines as dosage forms suitable for said cancer antigen peptides, are provided.The invention relates to water-in-oil emulsions which comprise as an effective ingredient either one or both of peptides selected from the group consisting of a peptide having an amino acid sequence of Cys Met Thr Trp Asn Gln Met Asn Leu (SEQ ID NO: 2), and a peptide having an amino acid sequence of Cys Tyr Thr Trp Asn Gln Met Asn Leu (SEQ ID NO: 3), as well as processes for preparation of said emulsion.

HLA-A24-restricted peptides derived from WT1 which have an activity to induce CTLs in vivo, polynucleotides encoding said peptides, cancer vaccines using those peptides or polynucleotides in vivo or in vitro, or the like are provided. The cancer vaccines of the present invention may be used to treat many cancer patients.
