To explore the functions of SPANXA1 in cancerous phenotypes CL1-5 cells were transfected with a SPANXA1 expressing vector and evaluated by cell proliferation, cell migration, Matrigel invasion and colony formation assays in vitro as well as mouse metastasis assays in vivo. The results indicated that the induction of SPANXA1 could reduce cell invasiveness. In the other hand, immunostaining showed that SPANXA1 was predominately located at the nucleoplasm.

经RT-PCR验证得知SPANXA1在CL1-0的表现量比CL1-5多100倍以上，於是我们将SPANXA1转染在CL1-5细胞株中，并测量活体外的细胞生长速度试验、细胞迁徙实验、Matrigel侵袭实验、癌细胞群落形成实验及小鼠活体内细胞转移能力，探讨SPANXA1对癌细胞性状的影响，结果发现增加SPANXA1会降低癌细胞的转移能力，在另一方面，我们利用免疫萤光染色法侦测出SPANXA1是存在於核质中，并以西方点墨法再次证实SPANXA1是存在於核质中。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
