OY-TES-1 is a member of the cancer/testis antigen family that is expressed in healthy testis tissue and certain types of cancerous tissue. The present study aimed to analyze the expression pattern of OY-TES-1 and serum anti-OY-TES-1 antibody concentration in patients with glioma. OY-TES-1 mRNA was detected in 28/36 (78%) of glioma cases using conventional reverse transcription polymerase chain reaction (RT-PCR) analysis. RT-quantitative-PCR revealed that OY-TES-1 was expressed at a higher level in glioma tissues compared with normal adult tissues (with the exception of testis tissue). Anti-OY-TES-1 antibodies were present in the serum of 5/36 (14%) of patients with glioma, but absent in all the serum samples from 107 healthy donors. Immunohistochemical analysis demonstrated that OY-TES-1 protein was expressed in all glioma tissues from patients with anti-OY-TES-1 antibody seropositivity. These results suggest that OY-TES-1 is a novel candidate for glioma immunotherapy.
OY-TES-1是癌症/睾丸抗原家族的成员，在健康的睾丸组织和某些类型的癌组织中表达。本研究旨在分析胶质瘤患者中OY-TES-1的表达模式及血清抗OY-TES-1抗体浓度。使用传统逆转录聚合酶链反应（RT-PCR）分析在36例胶质瘤病例中的28例（78%）检测到OY-TES-1 mRNA。逆转录定量PCR显示，与正常成人组织（睾丸组织除外）相比，OY-TES-1在胶质瘤组织中表达水平更高。36例胶质瘤患者中有5例（14%）血清中存在抗OY-TES-1抗体，但107名健康供者的所有血清样本中均未检测到。免疫组织化学分析表明，抗OY-TES-1抗体血清阳性患者的所有胶质瘤组织中均表达OY-TES-1蛋白。这些结果表明，OY-TES-1是胶质瘤免疫治疗的一个新候选物。
