PRESENCE OF ENZYME PC4 IN TESTICULAR TUMOR

激素以较大的非活性形式合成，然后被激活 通过酶消化。最近描述的一种酶，PC4，已经被 只在睾丸中发现。它在睾丸中的作用尚不清楚，就像 它所作用的荷尔蒙。本研究旨在测试 PC4在人睾丸肿瘤中的存在及其是否具有 在肿瘤形成中的作用。在接下来的一年里增加睾丸 肿瘤将由GCRC收集。

Hormones are synthesized in larger inactive forms and then are activated by enzymatic digestion. A recently described enzyme, PC4, has been found only in the testis. Its role in the testis is unknown, as is the hormone that it acts upon. The present study is designed to test for the presence of PC4 in human testicular tumors and to see if it has a role in tumor formation. During the coming year additional testicular tumors will be collected by the GCRC.
