Proteomic identification of necrozoospermia-related proteins / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To compare the proteomic differences between normal and necrozoospermic human spermatozoa.</p><p><b>METHODS</b>We isolated proteins from 30 ejaculates of 10 healthy donors and 3 specimens of a necrozoospermia patient by two-dimensional gel electrophoresis (2-DE), analyzed their 2-DE maps and identified some differentially expressed proteins by mass spectrometry.</p><p><b>RESULTS</b>A total of (905 +/- 57) and (792 +/- 28) proteins were isolated from the spermatozoal maps of the normal and necrozoospermic men, respectively, and 178 found to be differentially expressed in that of the necrozoospermia patient. The 6 missing protein spots in the necrozoospermic map were identified as sperm protein (human, accession No. 060904), zinc finger protein 174 (AW-1), F-actin capping protein alpha-3 subunit, testis-specific inhibitor of apoptosis, death domain receptor 3 soluble form (fragment) and peptide similar to the activator of CREM in the testis.</p><p><b>CONCLUSION</b>Six missing protein spots were identified in the necrozoospermic spermatozoal map which may be associated with the development of necrozoospermia.</p>
