肝细胞核因子1β(HNF1β)是一个转录因子,在早期器官发生中具有重要的作用,尤其是胰胆和泌尿生殖道。另外,HNF1β还是卵巢癌不同诊断方法的成熟的标记,且在透明细胞肾细胞癌中表现出不同的核表达。

最近,有研究人员阐释了HNF1β在卵黄囊瘤中的情况。卵黄囊瘤许多非精原细胞生殖细胞肿瘤中常见的类型。由于其具有广泛的组织学多样性,该疾病的诊断具有挑战性,其他的工具在检查生殖细胞瘤中也是很有用的。研究人员使用免疫组化染色研究了601个睾丸生殖细胞肿瘤中HNF1β在组织芯片(TMA)中的表达情况,其中包括了精原细胞瘤、胚胎癌、卵黄囊瘤、绒毛膜癌、畸胎瘤、原位生殖细胞瘤和正常组织。其表达模式与两个目前用于检测卵黄囊瘤的标记-磷脂酰肌醇聚糖3(GPC3)和α-胎蛋白(AFP)进行了比较。研究发现,HNF1β(细胞核染色)表现出了与GPC3和AFP(细胞质染色)不同的染色模式。HNF1β的敏感性和特异性分别为85.4%和96.5%,GPC3分别为83.3%和90.7%,AFP分别为62.5%和97.7%。

最后,研究人员指出,HNF1β是卵黄囊瘤的一个特异标记。因此,研究人员推荐HNF1β作为睾丸生殖细胞瘤的一个新的和强大的生物标记。
