Autor: Aline S.M. Cesar, Fernando H. Biase, Paula Ripamonte, Albino Luchiari Filho, Giovana K. Merighe, Flávio V. Meirelles

Publikováno v: Pesquisa Veterinária Brasileira, Vol 30, Iss 9, Pp 783-786 (2010)

Several characteristics are important in a traceability system of animal products, such as age at slaughter, breed composition, besides information of the productive chain. In general, the certification agent records information about the animals and

SummaryThe embryonic developmental block occurs at the 8-cell stage in cattle and is characterized by a lengthening of the cell cycle and an increased number of embryos that stop development. The maternal-embryonic transition arises at the same stage

Regulation and action of fibroblast growth factor 17 in bovine follicles

Autor: I. B. Costa, M. F. Machado, P. Ripamonte, Renée Laufer Amorim, Valério M. Portela, Jose Buratini, Christopher A. Price

Publikováno v: Journal of Endocrinology. 202:347-353

Fibroblast growth factor 17 (FGF17) is a member of the FGF8 subfamily that appears to be relevant to folliculogenesis and oogenesis, as the prototype member FGF8 is an oocyte-derived protein that signals to cumulus cells. FGF8 has structural and rece

Effects of FSH on the expression of receptors for oocyte-secreted factors and members of the EGF-like family during in vitro maturation in cattle

Autor: E. S. Caixeta, Christopher A. Price, Jose Buratini, M. F. Machado, P. Ripamonte

Publikováno v: Reproduction, fertility, and development. 25(6)

FSH induces expansion of bovine cumulus–oocyte complexes (COCs) in cattle, which can be enhanced by oocyte-secreted factors (OSFs). In this study it was hypothesised that FSH stimulates COC expansion in part from direct stimulation of the epidermal

Our objective was to estimate Bos primigenius taurus introgression in American Zebu cattle. One hundred and four American Zebu (Nellore) cattle were submitted to mtDNA, microsatellite and satellite analysis. Twenty-three alleles were detected in micr

Fibroblast growth factor-2 regulation of Sprouty and NR4A genes in bovine ovarian granulosa cells

Autor: P. Ripamonte, Christopher A. Price, Z.L. Jiang, Jose Buratini, Valério M. Portela

Publikováno v: Journal of cellular physiology. 226(7)

Fibroblast growth factors (FGFs) alter ovarian function, at least in part by inhibiting steroid hormone secretion and affecting survival of granulosa cells. The mechanism of action of FGFs in ovarian follicle cells is largely unknown; in the present
