Proteomic analyses of ram (Ovis aries) testis during different developmental stages
چکیده انگلیسی
Male reproductive capacity is essential for animal breeding and reproduction. In males, the testes produce sperm and secrete androgen, processes which require precise regulation by multiple proteins. The composition of proteins in the ram testes has not yet been studied systematically, thus, the application of proteomics to explore differential protein regulation during ram testes development is of great significance. In the present study, ram testes were studied at five different developmental phases to assess postnatal differences in protein regulation. Two dimensional electrophoresis (2-DE) was used to separate ram testes proteins at each developmental phase, yielding 45 different proteins, 37 of which were identified by Matrix Assisted Laser Desorption Ionization-Time of Flight-Time of Flight-Mass Spectrometry (MALDI-TOF/TOF-MS). Gene Ontology (GO) was used to specifically annotate the biological process, cellular composition, and molecular function of each identified protein. Most of the identified proteins were involved in structural formation, development, reproduction, and apoptosis of the testicular spermatogenic tissue and spermatozoa. Quantitative real time PCR (qRT-PCR), western blot and immunohistochemical methods were used to verify the proteins, and the results were consistent with that of 2-DE. The proteins that were different in abundance that were identified in this study can be used as biomarkers in future studies of ram reproduction.
