Micro-RNAs differentially expressed in comparative analysis of sperm samples wi...
Silva, Ricardo Tomaz da; Gomes, Matheus de Souza; Fujimura, Patrícia Tiemi; Ueira-Vieira, Carlos; Amaral, Laurence Rodrigues do; Beletti, Marcelo EmílioInfertility or subfertility in bovine males may be related to spermatic microRNAs (miRNAs), whose function seems to be associated with the regulation of gene expression, degradation or storage of messenger RNAs (mRNAs) for later translation into early embryonic development. Thus, the purpose of this study was to identify differentially expressed miRNAs in semen samples from bulls (Bos taurus) with low and high ...
Proteoma nuclear e micro-RNAs de espermatozoides de bovinos férteis e subférteis
Silva, Ricardo Tomaz daRESUMO - A compreensão da composição e fisiologia do espermatozoide é importante para compreender a subfertilidade transitória ou permanente em touros. Assim, objetivou-se com este trabalho avaliar as proteínas nucleares e micro-RNAs de espermatozoides de bovinos férteis e subférteis, na tentativa de se identificar marcadores moleculares de fertilidade e subfertilidade em touros. Para a avaliação de micro-RNAs ...
Correlação da morfometria e da compactação da cromatina de espermatozóides de t...
Silva, Ricardo Tomaz da38 PIVs carried through in two laboratories of the Uberaba MGBRASIL had been used in this work with the objective to evaluate the relationship between condensation chromatin and head morphometry of spermatozoa and cleavages and blastocyst formation rates using semen of zebu bulls with normal routine tests of fertility. Smears of semen stained with of Toluidine Blue and computer image analysis had been used to e...
