The melanoma antigen (MAGE) 3 gene may be a useful tumor specific marker since it is expressed in a variety of cancers.
MATERIALS & METHOD: The expression and intracellular location of MAGE 3 gene product were investigated in 40 squamous cell carcinomas, 2 tumor lines, 20 benign diseases, and 20 normal tissues of the head and neck. Immunohistochemical staining with anti-MAGE 3 mAb 57B was conducted from fresh frozen specimens. Correlations between MAGE 3 expression and clinicopathological parameters were also evaluated.
The MAGE 3 gene product was detected in squamous cell carcinomas (18/40, 45%) and in tumor cell lines (2/2, 100%), but not in benign diseases and normal tissues. No significant correlation was drawn between MAGE 3 expression and clinical parameters including clinical stages and metastasis.
These results show MAGE 3 antigen could represent a potential target for immunotherapy in head and neck squamous cell carcinomas.
黑色素瘤抗原(MAGE)3基因可能是一种有用的肿瘤特异性标志物,因为它在多种癌症中表达。
研究了40例头颈部鳞状细胞癌、2种肿瘤细胞系、20种良性疾病以及20种头颈部正常组织中MAGE 3基因产物的表达及细胞内定位。使用抗MAGE 3单克隆抗体57B对新鲜冷冻标本进行免疫组织化学染色。还评估了MAGE 3表达与临床病理参数之间的相关性。
在鳞状细胞癌(18/40,45%)和肿瘤细胞系(2/2,100%)中检测到MAGE 3基因产物,但在良性疾病和正常组织中未检测到。MAGE 3表达与包括临床分期和转移在内的临床参数之间未发现显著相关性。
这些结果表明,MAGE 3抗原可能是头颈部鳞状细胞癌免疫治疗的潜在靶点。
