The present invention relates to molecules, particularly polypeptides, more particularly immunoglobulins (e.g., antibodies), comprising a variant Fc region, wherein said variant Fc region comprises at least one amino acid modification relative to a wild-type Fc region, which variant Fc region binds FcγRIIIA and/or FcγRIIA with a greater affinity, relative to a comparable molecule comprising the wild-type Fc region. The molecules of the invention are particularly useful in preventing, treating, or ameliorating one or more symptoms associated with a disease, disorder, or infection. The molecules of the invention are particularly useful for the treatment or prevention of a disease or disorder where an enhanced efficacy of effector cell function (e.g., ADCC) mediated by FcγR is desired, e.g., cancer, infectious disease, and in enhancing the therapeutic efficacy of therapeutic antibodies the effect of which is mediated by ADCC.

The present invention is directed to an antigen found on the surface of rat and human pancreatic cancer cells and provides antibodies of high specificity and selectivity to this antigen as well as hybridomas secreting the subject antibodies. Methods for both the diagnosis and treatment of pancreatic cancer are also provided.

Ligase detection reaction is utilized to distinguish minority template in the presence of an excess of normal template with a thermostable ligase. This process can be carried out with a mutant ligase, thermostable ligase, or a modified oligonucleotide probe. This procedure is particularly useful for the detection of cancer-associated mutations. It has the advantage of providing a quantitative measure of the amount or ratio of minority template.

Disclosed herein among other MN/CA IX-related inventions are new MN/CA IX-specific antibodies generated from MN/CA IX-deficient mice, preferably monoclonal antibodies and immunoreactive fragments and engineered variants thereof. Subsets of the new antibodies are to either the proteoglycan-like (PG) domain or to the carbonic anhydrase (CA) domain of MN/CA IX, and methods are provided by which antibodies can be prepared to the other MN/CA IX domains. Such new MN/CA IX-specific antibodies, fragments and variants are useful diagnostically/prognostically and therapeutically for cancer and precancer. Particularly preferred are the new monoclonal antibodies, fragments and variants that are specific for the non-immunodominant epitopes of MN/CA IX, which antibodies are, among other uses, useful to detect soluble MN/CA IX (s-CA IX) in body fluids, alone but preferably in combination with antibodies specific to the immunodominant epitopes of MN/CA IX, for example, in a sandwich assay.

Mutant BNIP3 plays a functionally important role in the development of solid tumors and in resistance to chemotherapy and radiation treatments. The invention relates to methods of detecting cancer, methods of monitoring the progression of cancer, methods of identifying patients with cancer that is resistant to chemotherapy or radiation treatments, and diagnostic kits for performing the methods of the invention.

The present invention discloses methods and materials for delivering a cargo compound into a cancer cell. Delivery of the cargo compound is accomplished by the use of protein transduction domains derived from cupredoxins. The invention further discloses methods for treating cancer and diagnosing cancer.

Disclosed herein is the discovery of a soluble MN/CA IX (s-CA IX) in body fluids, such as, urine and serum. Said s-CA IX comprises the extracellular domain of CA IX or portions thereof. The predominant s-CA IX species is the extracellular domain comprising a proteoglycan-like (PG) domain and carbonic anhydrase (CA) domain, and having a molecular weight of about 50/54 kilodaltons (kd) upon Western blot. A smaller s-CA IX form of about 20 to about 30 kd comprising the CA domain or parts thereof, not linked to the PG domain, has also been found in body fluids. Diagnostic/prognostic methods for precancer and cancer that detect or detect and quantitate said s-CA IX in body fluids, are described. Also disclosed herein is the coexpression of CA IX and HER-2/neu/c-erbB-2 that provides parallel, alternative and potentially synergistic diagnostic/prognostic and therapeutic strategies for precancer and cancer. Further disclosed are new MN/CA IX-specific antibodies generated from MN/CA IX-deficient mice, preferably monoclonal antibodies and immunoreactive fragments and engineered variants thereof. Such new MN/CA IX-specific antibodies, fragments and variants are useful diagnostically/prognostically and therapeutically for cancer and precancer. Particularly preferred are the new monoclonal antibodies, fragments and variants that are specific for the non-immunodominant epitopes of MN/CA IX, which antibodies are, among other uses, useful to detect soluble MN/CA IX (s-CA IX) in body fluids, alone but preferably in combination with antibodies specific to the immunodominant epitopes of MN/CA IX, for example, in a sandwich assay.

The invention relates to members of the SSX family of genes, as well as their uses. Also a part of the invention are peptides derived from SSX molecules and the NY-ESO-1 molecule, which form complexes with HLA molecules, leading to lysis of cells presenting these complexes, by cytolytic T cells.

The present invention provides the isolation and cloning of WWOX, a novel WW domain-containing protein mapping to human chromosome 16q23.3-24.1, a region frequently affected in several cancers. This gene encodes a tumor suppressor with apoptotic functions. The invention provides WWOX nucleic acid- and polypeptide-based cancer therapies. The invention also provides methods for cancer detection, diagnosis and prognosis involving WWOX nucleic acids and polypeptides.

In order to identify genes that can serve as indicators for predicting the effectiveness of drug treatments in cancers and provide novel methods for predicting the effectiveness of treatments with drugs targeting said genes, transcriptome sequencing was performed of diffuse-type gastric cancer. As a result, in-frame fusion transcripts between the CEP55 gene and the RET gene were identified. It was also found that said gene fusions induce activation of RET protein, thereby causing canceration of cells. Further, it was demonstrated that the RET protein activation and canceration caused by said gene fusion can be suppressed by using a RET tyrosine kinase inhibitor, and that treatments with a RET tyrosine kinase inhibitor are effective in patients with detection of said gene fusion.

The present invention provides the following: a method for efficiently producing a reagent for detecting an antibody that specifically binds with an insoluble antigen protein present in a liquid sample; a reagent for antibody detection produced by the production method; and a use of the antibody. In a step for solubilizing an antigen protein, it is possible to efficiently solubilize and recover the antigen protein by using a cationizing agent; therefore, when compared to conventional methods, it is possible to efficiently produce a reagent for detecting an antibody that has bound to multiple antigen protein molecules in a carrier.
