Product Details

The LX-CT10.5 monoclonal antibody reacts with human melanoma-associated antigen C2 (MAGEC2), also known as CT10 and HCA587. MAGEC2 is one of many cancer/testis (CT)-antigens. CT antigens are thought to repress the expression of some genes necessary for cellular differentiation. Normally, MAGEC2 expression is restricted to male germ cells in the testis however, MAGE-C2 is abnormally expressed in a wide variety of malignancies, including hepatocellular carcinoma, melanoma, bladder cancer, breast cancer, sarcoma, and lung cancer. MAGEC2 positive tumors are associated with reduced overall survival rates in prostate, hepatocellular, breast, and non-small cell lung carcinomas. Since MAGEC2 is highly expressed in cancer cells but absent from normal adult tissues it is considered an ideal target for cancer immunotherapy. The LX-CT10.5 antibody is useful for identifying MAGEC2 expressing cells in immunohistochemical studies.

Hepatocellular carcinoma-associated antigen 587/melanoma antigen gene (HCA587/MAGEC2) is a cancertestis antigen, which is highly expressed in various types of tumors, but not in normal tissues with the exception of male germline cells. HCA587/MAGEC2 has been previously recognized as a tumorspecific target for immunotherapy; however, its biological functions have been relatively understudied. To investigate the function of HCA587/MAGEC2, the amino acid sequence of HCA587/MAGEC2 was analyzed by bioinformatics and it was demonstrated that HCA587/MAGEC2 contains a 9amino acid transactivation domain which may mediate the interaction of most transcription factors with TATAbox binding protein associated factor 9 (TAF9), a general transcription coactivator. Coimmunoprecipitation experiments revealed that HCA587/MAGEC2 interacted with TAF9 in transfected 293T and in A375 melanoma cells endogenously expressing HCA587/MAGEC2, and confirmed the endogenous interaction of HCA587/MAGEC2 and TAF9 within cells. Endogenous HCA587/MAGEC2 and TAF9 were demonstrated to be colocalized principally in the nucleus of tumor cells using immunofluorescence. Glutathione-S-transferase pulldown experiments demonstrated that HCA587/MAGEC2 interacts with TAF9 directly and the conserved region in the TAF9 may becrucial for HCA587/MAGEC2 binding. The present study demonstrated that the cancertestis antigen HCA587/MAGEC2 directly interacted with TAF9, which may provide novel information for identifying the oncogenic functions of HCA587/MAGEC2 in tumor cells.

Mucosal melanoma is a rare disease, which differs from its cutaneous counterpart genetically and for its clinical behaviour. Moreover this is a heterogeneous disease based on the tissue of origin. As CT7 and CT10 are highly expressed in cutaneous melanoma and are immunogenic in this disease, we analysed their expression throughout the different subtypes of mucosal melanoma and tumor development. We detected a frequent expression of CT7 in primaries and corresponding metastases (55%) as well as for CT10 (30%). This expression resulted to be heterogeneous in the same tumor specimen and moreover influenced by the tissue of origin. Our results support the role of these antigens in immunotherapy for mucosal melanoma.

Melanoma-associated gene C2 (MAGEC2) is a recently identified cancer testis antigen expressed in normal testicular and placental tissue. It has been detected in some human carcinomas, but its expression in primary testicular germ cell tumors is unknown. Immunohistochemistry was used to study MAGEC2 protein in 325 primary testicular germ cell tumors, including 94 mixed germ cell tumors. Seminomatous and non-seminomatous components were separately arranged and evaluated on tissue microarrays. MAGEC2 expression was compared with POU5F1 (OCT3/4), SOX2, SOX17, KIT and TNFRSF8 (CD30). The mouse monoclonal anti-MAGEC2 antibody (clone LX-CT10.5) revealed a nuclear MAGEC2 expression with little or no background staining. MAGEC2 expression was found in 238 of 254 seminomas (94%), but not in embryonal carcinomas (n=89). POU5F1 (OCT3/4) was positive in 97% of seminomas and all embryonal carcinomas. In contrast, KIT was positive in 94% of seminoma but also in 8% of embryonal carcinomas. TNFRSF8 (CD30) and SOX2 were negative in seminoma and positive in embryonal carcinoma (96 and 90%, respectively). SOX17 was positive in 94% of seminoma and negative in embryonal carcinoma. We conclude that MAGEC2 allows a reliable distinction of seminoma from embryonal carcinomas. Therefore, MAGEC2 represents an additional tool for the differential diagnosis of testicular germ cell tumors.

Zhuang, R., et al. (2006). "Generation of monoclonal antibodies to cancer/testis (CT) antigen CT10/MAGE-C2" Cancer Immun 6: 7. PubMed

CT10/MAGE-C2 is a recently identified antigen that, typically of cancer/testis (CT) antigens, can be found in various malignant tumors and in normal adult testis. As with many other CT antigens, our knowledge is based mainly on mRNA expression data. In the present study, we describe the generation of mAbs to CT10/MAGE-C2 for the analysis of its protein expression. Newly generated clones were chosen based on their reactivity in ELISA, immunoblotting, and immunohistochemistry (IHC). Emphasis was put on the reactivity of newly generated reagents on formalin-fixed, paraffin-embedded tissue to ensure their applicability to archival material. Eventually we selected two clones, LX-CT10.5 and LX-CT10.9, that showed intense reactivity to CT10/MAGE-C2 protein and CT10/MAGE-C2 mRNA-positive cell lines, but no cross-reactivity with other CT antigens. Both mAbs show superior staining characteristics in IHC and are applicable to frozen and paraffin sections. In testis, CT10/MAGE-C2 displays the typical CT pattern with regard to staining of germ cells, which is intense during the early maturation stages. In tumors, we analyzed a limited number of cases displaying the typical heterogeneous CT expression pattern. Interestingly, immunoreactivity was seen solely in the nucleus: No staining was seen in the cytoplasm of tumor cells.
