Shortening of dioestrus in female dogs using cloprostenol sodium at different stages of dioestrus

Journal of Veterinary and Animal Sciences, 2021
A study was conducted in 18 healthy, fertile, non-pregnant, dioestrous female dogs to evaluate the efficacy of PGF2α analogue (cloprostenol sodium) in shortening the dioestrus.

The corpora lutea proangiogenic state of VEGF system components is turned to antiangiogenic at the later phase of the oestrous cycle in cows

Animal, 2015
Blood vessel expansion and reduction in the corpus luteum (CL) is regulated by the vascular endothelial growth factor (VEGF) system and linked to the maintenance of the CL. The VEGF system has both angiogenic and antiangiogenic ligands and receptors. Our

Luteal phospholipase A2 activity increases during functional and structural luteolysis in pregnant rats [PDF]

, 1999
We determined cytosolic phospholipase A2 activity of the corpus luteum during luteolysis in pregnant and post-partum rats. Phospholipase A2 activity and its metabolite prostaglandin F2α in the corpus luteum remarkably increased just before parturition ...

Roles of prostaglandin F2alpha and hydrogen peroxide in the regulation of Copper/Zinc superoxide dismutase in bovine corpus luteum and luteal endothelial cells

Reproductive Biology and Endocrinology, 2012
Background Prostaglandin F2alpha (PGF) induces luteolysis in cow by inducing a rapid reduction in progesterone production (functional luteolysis) followed by tissue degeneration (structural luteolysis).

Mechanisms of angioregression of the corpus luteum

Frontiers in Physiology, 2023
The corpus luteum is a transient ovarian endocrine gland that produces the progesterone necessary for the establishment and maintenance of pregnancy. The formation and function of this gland involves angiogenesis, establishing the tissue with a robust ...

New Aspects of Corpus Luteum Regulation in Physiological and Pathological Conditions: Involvement of Adipokines and Neuropeptides

Cells, 2022
The corpus luteum is a small gland of great importance because its proper functioning determines not only the appropriate course of the estrous/menstrual cycle and embryo implantation, but also the subsequent maintenance of pregnancy.

Histomorphometric and immunohistochemistry studies of the corpus luteum of bedouin goats reared in arid environment [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2023
The aim of this work was to study the histomorphometry and the immunohistochemistry of the Corpus luteum (CL) of Bedouin goat living in arid zones. Pregnant and non-pregnant females ovaries were collected from slaughterhouses, weighed, measured and then ...

Inhibition of luteolysis and embryo-uterine interactions during the peri-implantation period in pigs.

Society of Reproduction and Fertility supplement, 2019
Inhibition of luteolysis and establishment of pregnancy in pigs results from oestrogen secretion by the conceptuses and requires progesterone produced by the corpus luteum (CL).

Transcriptome analysis reveals differences in mechanisms regulating cessation of luteal function in pregnant and non-pregnant dogs

BMC Genomics, 2017
Background In the domestic dog, corpora lutea (CL) are the only source of progesterone (P4), both in pregnant and non-pregnant cycles because there is no placental steroidogenesis.

Supplementation with long-acting progesterone in early diestrus in beef cattle: I. effect of artificial insemination on onset of luteolysis.

Domestic Animal Endocrinology, 2019
Progesterone (P4) supplementation in early diestrus advances changes in the endometrial transcriptome, stimulating embryonic development. However, it also induces early onset of luteolysis.
