    The expression of MAGE-n in HCC and non-cancerous tissues were analyzed by using in-situ hybridization technique.
    然后,用原位杂交技术分析了肝癌组织、肝正常组织及其它非肿瘤组织中MAGE—n基因的表达情况;
    And no expression was detected in normal, liver cirrhosis and non-cancerous tissues, which suggest that MAGE-n could be potentially used as a target for immunotherapy for HCC.
    检测到有 MAGE呗的表达,在正常肝组织、肝硬化组织及其它非肿瘤组织中未检测到MAGE-n的表达。 MAGE-n的这种表达模式,与其他MAGE基因相同,提示其可作为肝癌免疫治疗的靶分子。
