Because progesterone (P4) is essential for pregnancy establishment and maintenance, we investigated the effect of increased concentrations of P4 on embryonic attachment and concentrations of pregnancy-associated glycoproteins (PAG). Additionally, we

Publikováno v: Reproduction. 165:93-101

In brief Endometrial and luteal synthesis of prostaglandin F2alpha (PGF2A) occurs before and during luteolysis and is critical for luteal regression. This study demonstrates that PGF2A stimulates further PGF2A synthesis (autoamplification) apparently

Endometrial and luteal responses to a prostaglandin F2alpha pulse: a comparison between heifers and mares

Autor: Rafael R, Domingues, O J, Ginther, Victor, Gomez-Leon, Thadeu, Castro, Milo C, Wiltbank

Publikováno v: Biology of Reproduction. 106:979-991

In heifers and mares, multiple pulses of prostaglandin F2alpha (PGF) are generally associated with complete luteal regression. Although PGF pulses occur before and during luteolysis, little is known about the role of minor PGF pulses during preluteol

SMAD6 inhibits granulosa cell proliferation and follicle growth rate in carrier and noncarrier heifers of the Trio allele

Autor: Rafael R Domingues, Fabiana S Andrade, Joao Paulo N Andrade, Victor Gomez-Leon, Guilherme Madureira, Sadrollah M Moghbeli, Marco R B Mello, B. W. Kirkpatrick, Milo C. Wiltbank

Publikováno v: Reproduction.

Cattle are generally considered a monovular species; however, recently a bovine high fecundity allele, termed the Trio allele, was discovered. Carriers of Trio have an elevated ovulation rate (3 to 5) while half-sibling noncarriers are monovular. Car
