Arq. bras. med. vet. zootec. (Online); 73 (1), 2021

The objective of this study was to quantify the superovulatory response and embryo production of Brazilian Bergamasca sheep and to evaluate the link to the follicular condition before superovulatory treatment, as a reference for selection of donors with potential for superovulation. Follicular population...

Biol. Res; 54 (), 2021

BACKGROUND: PGF2α is essential for the induction of the corpus luteum regression which in turn reduces progesterone production. Early growth response (EGR) proteins are Cys2-His2-type zinc-finger transcription factor that are strongly linked to cellular proliferation, survival and apoptosis. Rapid eleva...

Endometrial prostaglandin F2α in vitro production and its modulation regarding dominant follicle position in cattle

Bressan, Fabiana Fernandes; Membrive, Claudia Maria Bertan; Goissis, Marcelo Demarchi; Marques, Vanessa Belentani; Cunha, Pauline Martins da; Binelli, Mario.

Braz. J. Vet. Res. Anim. Sci. (Online); 55 (2), 2018

Prostaglandin F2α (PGF2α) determines luteolysis in cattle, and the ability to manipulate its endogenous synthesis is indispensible for large-scale animal breeding. Estradiol (E2) and progesterone (P4) modulate several molecular pathways in endometrial cells, including the synthesis of PGF2α; however, ...
