Models of Endocrine‐Disrupting Effects: Human Placental Steroidogenesis

Basic &Clinical Pharmacology &Toxicology, Volume 137, Issue 2, August 2025.
ABSTRACT Endocrine disruption during pregnancy has gained increasing interest as epidemiological studies report associations of exposures and adverse effects on fetal growth, followed by effects on the growing child and ultimately in the adult. When studying endocrine disruption during pregnancy, the placental steroidogenesis is difficult to model, as ...

Plasma Estradiol and Endometrial Edema Profile in Acyclic Mares After Single Administration of 17‐β Estradiol, Estradiol Benzoate and Estradiol Cypionate

Reproduction in Domestic Animals, Volume 60, Issue 8, August 2025.
ABSTRACT A longer endometrial exposure to estradiol before progesterone has been shown to be beneficial in cyclic and acyclic recipient mares. Therefore, the selection of an estradiol ester that promotes longer endometrial exposure to estradiol using a single administration would be advantageous when preparing acyclic mares as embryo recipients.

Mutant mouse models and their contribution to our knowledge of corpus luteum development, function and regression

Reproductive Biology and Endocrinology, 2003
The corpus luteum is a unique organ, which is transitory in nature. The development, maintenance and regression of the corpus luteum are regulated by endocrine, paracrine and autocrine signaling events.

Biosynthesis of retinal in bovine corpus luteum

Journal of Lipid Research, 1974
Bovine corpus luteum tissue was sliced and incubated with β-[15,15′-3H]carotene. The conversion of radioactive β-carotene into radioactive retinal was substantiated utilizing column chromatography, thin-layer chromatography, high-speed liquid ...

Molecular mechanism of anti-luteolysis during the maternal recognition of pregnancy in cows [PDF]

Eurasian Journal of Veterinary Sciences
Maintenance of secretion of progesterone from the ovarian corpus luteum (CL) is essential for establishment of pregnancy in cows. The luteolytic prostaglandin (PG) is PGF2ot in cows causing regression of the corpus luteum and cessation of progesterone ...

Follicular Development Dynamics and Plasma Progesterone Profile during the Estrous Cycle of Dairy Cows

Animal Production: Indonesian Journal of Animal Production, 2008
A total of five local Friesian cows, 4 to 5 years, healthy, reproductively sound, were used in the study to understand the development dynamics of dominant follicles and plasma progesterone profile during estrous cycle.

Macrophages regulate corpus luteum development during embryo implantation in mice.

Journal of Clinical Investigation, 2013
Macrophages are prominent in the uterus and ovary at conception. Here we utilize the Cd11b-Dtr mouse model of acute macrophage depletion to define the essential role of macrophages in early pregnancy.

A potential function of RLIP76 in the ovarian corpus luteum

Journal of Ovarian Research, 2019
s Ral interacting protein of 76 kDa (RLIP76) is multifunctional protein localized and distributed in the plasma membrane, cytosol, and nucleus of the cell. In tumorigenesis, RLIP76 emerges as a common feature for the solid tumor growth.
