The aims of the present study were to evaluate expression levels of \u00df-tubulin 2C (TUBB2C), heat shock protein 10 (HSP10), hexokinase 1 (HXK1) and superoxide dismutase 1 (SOD1) in spermatozoa from Holstein bulls with varying fertility using western blotting and to analyse the biological networks of these key sperm proteins using a bioinformatics software (Metacore; Thomson-Reuters, Philadelphia, PA, USA). The rationales behind this study were that the sperm proteins play crucial roles in fertilisation and early embryonic development in mammals and ascertaining the biological networks of the proteins helps us better understand sperm physiology and early mammalian development. The results showed that expression of SOD1 was higher in spermatozoa from high fertility bulls (P &amp;lt; 0.05) and that SOD1 is the best protein to diagnose bulls based on the fertility index (P &amp;lt; 0.05). Using Metacore analysis, we identified an SOD1 network with pathways and linkages with other relevant molecules. We concluded that SOD1 sperm expression is associated with in vivo bull fertility. The findings are important because they illuminate molecular and cellular determinants of sperm viability and the identified protein markers can be used to determine bull fertility.<\/jats:p>","DOI":"10.1071\/rd14399","type":"journal-article","created":{"date-parts":[[2015,4,21]],"date-time":"2015-04-21T00:24:09Z","timestamp":1429575849000},"page":"1405-1413","source":"Crossref","is-referenced-by-count":12,"title":["Sperm superoxide dismutase is associated with bull fertility"],"prefix":"10.1071","volume":"28","author":[{"given":"Kamilah E.","family":"Grant","sequence":"first","affiliation":[{"name":"ADepartment of Animal and Dairy Sciences, Mississippi State University, 4025 Wise Center, Mississippi State, MS 39762, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodrigo V.","family":"de Oliveira","sequence":"additional","affiliation":[{"name":"ADepartment of Animal and Dairy Sciences, Mississippi State University, 4025 Wise Center, Mississippi State, MS 39762, USA."},{"name":"BDepartment of Animal Science, Federal University of Ceara, Fortaleza, 60355-970, Brazil."},{"name":"HPresent address: Department of Animal Production \u2013 Animal Sciences Institute, Federal Rural University of Rio de Janeiro \u2013 UFRRJ, Serop\u00e9dica-RJ, 23890-000, Brazil."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bettye Sue","family":"Hennington","sequence":"additional","affiliation":[{"name":"CTougaloo College, Department of Biology, 500 W County Line Rd, Tougaloo, MS 39174, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aruna","family":"Govindaraju","sequence":"additional","affiliation":[{"name":"ADepartment of Animal and Dairy Sciences, Mississippi State University, 4025 Wise Center, Mississippi State, MS 39762, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andy","family":"Perkins","sequence":"additional","affiliation":[{"name":"DDepartment of Computer Science and Engineering, 665 George Perry Street, Mississippi State, MS 39762, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Stokes","sequence":"additional","affiliation":[{"name":"EDepartment of Basic Sciences, Mississippi State University, 240 Wise Center Drive, Mississippi State, MS 39762, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dennis","family":"Rowe","sequence":"additional","affiliation":[{"name":"FDepartment of Plant and Soil Sciences, Mississippi State University, 32 Creelman Street, Mississippi State, MS 39762, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Einko","family":"Topper","sequence":"additional","affiliation":[{"name":"GAlta Genetics, N8350 High Road, Watertown, WI 53094, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdullah","family":"Kaya","sequence":"additional","affiliation":[{"name":"GAlta Genetics, N8350 High Road, Watertown, WI 53094, USA."},{"name":"IPresent address: Department of Reproduction and Artificial Insemination, Selcuk University, Konya, 42030, Turkey."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arlindo","family":"Moura","sequence":"additional","affiliation":[{"name":"BDepartment of Animal Science, Federal University of Ceara, Fortaleza, 60355-970, Brazil."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erdogan","family":"Memili","sequence":"additional","affiliation":[{"name":"ADepartment of Animal and Dairy Sciences, Mississippi State University, 4025 Wise Center, Mississippi State, MS 39762, USA."},{"name":"JCorresponding author.
