| abstractText | A unique isozyme of angiotensin-converting enzyme (ACE) is produced in large amounts by developing germ cells and is referred to as testis ACE. This protein results from the transcriptional recognition of a sperm-specific promoter during spermatogenesis. The expression within germ cells of testis ACE mRNA was studied using in situ hybridization, ribonuclease (RNase) protection, and Northern analysis. In parallel, testis ACE protein expression was measured through use of Western blot analysis and immunohistochemistry. Although testis ACE protein is first detected in step 10 spermatids, testis ACE mRNA is first detected in a developmentally younger cell population, late pachytene spermatocytes. Thus, testis ACE mRNA is translationally arrested for a period of several days until late in spermiogenesis. |
