Follistatin secretion by the ovary is not directly related to PGF2α induced luteolysis in the ewe

, 2010
Follistatin is a monomeric glycoprotein, expressed ubiquitously, and found in greatest levels in ovarian tissue. Our previous studies have demonstrated that ovarian venous follistatin levels are elevated at the same time as spontaneous luteolysis in ...

Efficacy of Supplementary Guanidinoacetic Acid at Different Dietary Crude Protein Levels on the Productive Performance, Egg Quality, Intestinal Morphology, Antioxidative Status, and Serum Metabolites of Aged Laying Hens Exposed to High Ambient Temperatures

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
0.15% GAA supplementation enhanced body weight and productive performance in heat‐stressed aged hens. Serum creatine, nitric oxide, and antioxidant capacity increased with GAA, while egg quality remained unaffected. One percent reduced protein diet with GAA maintained performance, whereas 2% reduction caused losses.

Rapid accumulation of polymorphonuclear neutrophils in the Corpus luteum during prostaglandin F(2α)-induced luteolysis in the cow. [PDF]

PLoS ONE, 2012
Prostaglandin F(2α) (PGF(2α)) induces luteolysis within a few days in cows, and immune cells increase in number in the regressing corpus luteum (CL), implying that luteolysis is an inflammatory-like immune response.

Antimicrobial prescribing guidelines for horses in Australia

Australian Veterinary Journal, Volume 103, Issue 12, Page 781-889, December 2025.
The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.

Specific effects on the reproductive function including fertility relevant for cumulative risk assessment of pesticide residues

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract According to the ‘EFSA‐SANTE Action Plan on Cumulative Risk Assessment for pesticides residues’, EFSA, with the support of a working group, undertook the identification of specific effects on male and female reproductive function, including fertility, that are considered relevant for grouping pesticide residues and for assessing ...

Estrogen Promotes Luteolysis by Redistributing Prostaglandin F2α Receptors Within Primate Luteal Cells

Reproduction, 2015
Prostaglandin F2α (PGF2α) has been proposed as a functional luteolysin in primates. However, administration of PGF2α or prostaglandin synthesis inhibitors in vivo both initiate luteolysis.

Disruption of ovarian function and induction of apoptosis in female mice by Brefeldin A: Mechanistic insights into reproductive toxicity

Animal Models and Experimental Medicine, Volume 8, Issue 11, Page 2053-2068, November 2025.
Brefeldin A (BFA) significantly inhibits oocyte release and induces apoptosis in ovarian granulosa cells by disrupting follicular development. It downregulates proliferation‐associated genes, reduces SIRT1/SIRT6 proteins, and upregulates cell cycle inhibitors P21 and P16. Additionally, BFA impairs estrogen synthesis and affects ovarian function through

Table_1_The Interaction Between Nodal, Hypoxia-Inducible Factor 1 Alpha, and Thrombospondin 1 Promotes Luteolysis in Equine Corpus Luteum.DOCX

, 2019
The regulation of corpus luteus (CL) luteolysis is a complex process involving a myriad of factors. Previously, we have shown the involvement of Nodal in functional luteolysis in mares.

Penicillin and Gentamicin Concentrations in the Uterine Fluid of Non‐Pregnant Mares Following a Single Intrauterine Infusion

Journal of Veterinary Pharmacology and Therapeutics, Volume 48, Issue 5, Page 389-396, September 2025.
ABSTRACT Despite their widespread clinical use, there is limited pharmacokinetic data for many equine intrauterine antimicrobials. This study aimed to measure the concentration of gentamicin and penicillin in the uterine fluid of mares following infusion of either a standard (PPGent) or long‐acting (LA‐PPGent) compounded formulation.
