Abstract

In the fight against cancer, new and more specific targets are needed. Here, we offer an example of a potential target that has not been widely studied, namely the syncytin protein. Syncytin is expressed mainly in the human placenta and is implicated in placental syncytiotrophoblast cell fusion. Not much is known about the role of syncytin in cancer, but the existing data call for more intense research. Its retroviral origin and particular tissue distribution make syncytin an interesting potential target in cancer therapy.

摘要

在对抗癌症的斗争中,需要新的、更具特异性的靶点。在此,我们提供一个尚未得到广泛研究的潜在靶点的例子,即合胞素蛋白。合胞素主要在人胎盘中表达,并与胎盘合体滋养层细胞融合有关。关于合胞素在癌症中的作用知之甚少,但现有数据表明需要进行更深入的研究。其逆转录病毒起源和特殊的组织分布使合胞素成为癌症治疗中一个有趣的潜在靶点。
