Full textThe aim of this study was to determine the relative expression of genes involved in transport of monocarboxylates (Mct1, Mct2, Mct3 e Mct4) and oogenesis specific genes (Bmp15, Gdf9 and Has2) in immature and mature bovine cumulus-oocyte complexes (COC) after selection by BCB. Immature COCs underwent morphological selection and were stained with 26 mM BCB for 90 min. Based on ooplasm staining, oocytes were distributed in two groups BCB+ (blue color) and BCB- (non-stained). The holding control group was exposed to the same incubation conditions as stained COCs, but without BCB. Control group was submitted to in vitro maturation (IVM) immediately after morphological selection. mRNA expression was investigated by RT-PCR in COCs before and after IVM. No relationship was observed in the relative expression of Has2, Gdf9, Bmp15 or Mct1, 2 and 4 transcripts between BCB- and BCB+ COCs. Transcripts analysis showed that Gdf9 and Bmp15 in BCB+, BCB- and holding groups were upregulated (p < 0.05) before IVM, while Has2 was up-regulated (p < 0.01) after IVM in the control group. Others genes remained stable during maturation (Mct1, 2 and 4). The increase in relative abundance of some transcripts during IVM may be attributed to incubation conditions during the BCB test. Our results showed, for the first time, Mct1, 2 and 4 expression in bovine COCs. Mct1 and Mct4 transcripts were present in denuded oocytes and cumulus cell, while Mct2 was detected only in cumulus cells. These differences between the three isoforms in localization suggest unique roles for each in monocarboxylate transport during maturation.

Full textParacrine factors secreted by the oocyte (oocyte-secreted factors, OSFs) regulate a broad range of cumulus cell functions. The capacity of oocytes to regulate their own microenvironment by OSFs may in turn contribute to oocyte developmental competence. The aim of this thesis was to examine whether cumulus cells exhibit a low incidence of apoptosis due to their close association with oocytes and their exposure to OSFs, and to investigate if OSFs have a direct influence on bovine oocyte developmental competence during in vitro maturation (IVM). This thesis includes a series of studies designed to examine by various means the nature of the paracrine network of bone morphogenetic proteins (BMPs) and their binding proteins involved in the regulation of cumulus cell apoptosis. OSFs, in particular BMP- 15 and BMP-6, but not growth differentiation factor 9 (GDF-9), reduced apoptosis of cumulus cells by following a gradient from the site of the oocytes. Morever, follistatin and a BMP6 neutralizing antibody, which antagonized the anti-apoptotic effects of BMP15 and BMP6, respectively, whether alone or combined, blocked ~50% of the antiapoptotic actions of oocytes. These results demonstrated that OSFs, particularly BMP-15 and BMP-6, maintain the low incidence of apoptosis by establishing a localized gradient of bone morphogenetic proteins. Results from the present thesis also demonstrated that OSFs enhance oocyte developmental competence during IVM, whether in their native form as an uncharacterized mix of growth factors secreted by the oocyte, throughout the oocyte maturation period, or as exogenous BMP-15 and GDF-9, during the first 9 hour of IVM. Also, OSFs improved embryo quality as evident by increased blastocyst total and trophectoderm cell numbers. These results were further verified in neutralization experiments of the exogenous growth factors and of the native OSFs. Follistatin and the kinase inhibitor SB-431542, which antagonize BMP-15 and GDF-9, respectively, neutralized the stimulatory effects of the exogenous growth factors, and impaired the developmental competence of control cumulus-oocyte complexes (COCs). The work presented in this thesis has provided multiple lines of evidence that OSFregulation of the COC microenvironment is an important determinant of cumulus cell apoptosis and oocyte developmental programming.
