Associated and independent comparisons between the two largest follicles preceding follicle deviation in cattle
(2003-02-01)
Follicle diameters and concentrations of follicular fluid factors were studied in the two largest follicles (F1 and F2) using F1 diameters in increments of 0.2 mm (equivalent to 4 h intervals) and extending from 7.4 to 8.4 ...

Follicle populations and gene expression profiles of Nelore and Angus heifers with low and high ovarian follicle counts
(2019-02-01)
The number of antral follicles counted (AFC) by ultrasound is associated with fertility in cattle. Cows with higher follicle count (HFC) have higher performance in reproductive-assisted technologies than cows with lower ...
Localization of angiotensin receptor type 2 in fetal bovine ovaries
(Elsevier B.V., 2016-05-01)
In the ovary, angiotensin II (ANGII) acts through the type 2 receptor (AGTR2) to induce ovulation and may play a role in follicle atresia. In this study, we determined the expression of AGTR2 mRNA and protein during follicle ...
Expression of fibroblast growth factor 10 and cognate receptors in the developing bovine ovary
(Elsevier B.V., 2014-06-01)
In the mammalian ovary, FGF10 is expressed in oocytes and theca cells and is a candidate for paracrine signaling to the developing granulosa cells. To gain insight into the participation of FGF10 in the regulation of fetal ...
Evidence that fibroblast growth factor 10 plays a role in follicle selection in cattle
(Csiro Publishing, 2017-01-01)
There is evidence that regulation of follicle selection in cattle involves locally produced growth factors. In the present study, we investigated the expression of members of the fibroblast growth factor (FGF) 7 family ...
PTEN and FOXO3 expression in the prenatal and postnatal human ovary
(Springer/Plenum Publishers, 2020-05)
Purpose: The objective of this study was to analyse the expression and cellular localization of FOXO3, pFOXO3 and PTEN throughout human ovary development both before and after birth. Methods: Foetal, pubertal and adult ...
Temporal interrelationships among luteolysis, FSH and LH concentrations and follicle deviation in mares
(2000-03-01)
The effect of altered LH concentrations on the deviation in growth rates between the 2 largest follicles was studied in pony mares. The progestational phase was shortened by administration of PGF2α on Day 10 (Day 0=ovulation; ...
