The significant role of C-type natriuretic peptide (CNP) and its receptor 2 (NPR2) in regulating oocyte meiotic maturation facilitating communication between oocytes surrounding cumulus cells has been well-documented various mammalian species, including mice, cattle swine. However, further investigation is needed to ascertain whether receptors (NPRs) are involved other essential ovarian functions. Hence, this study aimed explore the potential involvement NPRs regulation expansion bovine...

Summary The Grb14 protein is a member of the Grb7 family. This family acts by binding to tyrosine kinase receptors, promoting cell proliferation and differentiation. There evidence involvement factors in bovine oocyte maturation process. However, has not been studied for cumulus–oocyte complexes (COCs). aim present study was characterize mRNA expression COCs during follicular development. Furthermore, we demonstrated that regulated estradiol. assessed 480 from follicles different sizes (1–3,...

The objective of this study was to investigate the mRNA expression and protein localization Grb10 gene in bovine cumulus-oocyte complexes (COCs) from different follicle sizes. Firstly, it investigated correlate with maturation rates. COCs follicles at 1-3, 4-6, 6-8 >8mm were used evaluate by qRT-PCR assay nuclear It observed that more competent oocytes (from >8mm; P>0.05), had lower levels when compared 1-3 4-6mm (P>0.05). After performed an immunofluorescence...

Cursos extracurriculares são uma oportunidade de praticar e aprender assuntos muitas vezes não abordados no decorrer um curso. Este trabalho objetivou verificar a percepção dos discentes do início final Curso Técnico em Agropecuária Colégio Politécnico da UFSM relação aos cursos extracurriculares. Por meio questionário foi observado que os estudantes consideram importantes para formação profissional. Também grande parte já participou atividades semelhantes. Os resultados obtidos demonstram...
