多能性转录调控因子POU5F1 (OCT4)、NANOG和SOX2在胚胎癌(EC)中高表达。与OCT4和NANOG相比,SOX2尚未在早期人类生殖细胞谱系或原位癌(CIS)中被证实,原位癌是睾丸生殖细胞肿瘤(tgct)的前体。在这里,我们使用三种不同的抗体,通过原位杂交和免疫组织化学分析了SOX2在CIS和显性tgct中的表达,以及正常的妊娠中期和晚期胎儿、青春期前和成年睾丸中的表达。与早期研究相反,我们在大多数CIS细胞中检测到SOX2 mRNA。我们还检测到一种一抗在CIS细胞中具有斑点状核SOX2免疫反应性,而其他一抗则不明显。这些结果首次证实了SOX2基因在CIS中的表达,并提出了转录后调控的可能性,最有可能的是sumoylation是限制SOX2在这些细胞中的作用的机制。
The transcriptional regulators of pluripotency, POU5F1 (OCT4), NANOG and SOX2, are highly expressed in embryonal carcinoma (EC). In contrast to OCT4 and NANOG, SOX2 has not been demonstrated in the early human germ cell lineage or carcinoma in situ (CIS), the precursor for testicular germ cell tumours (TGCTs). Here, we have analysed SOX2 expression in CIS and overt TGCTs, as well as normal second and third trimester fetal, prepubertal and adult testes by in situ hybridisation and immunohistochemistry using three different antibodies. In contrast to earlier studies, we detected SOX2 mRNA in most CIS cells. We also detected speckled nuclear SOX2 immunoreactivity in CIS cells with one primary antibody, which was not apparent with other primary antibodies. The results demonstrate SOX2 gene expression in CIS for the first time and raise the possibility of post-transcriptional regulation, most likely sumoylation as a mechanism for limiting SOX2 action in these cells.
