Limbic progesterone receptors regulate spatial memory

open access: yesScientific Reports, 2023
Progesterone and its receptors (PRs) participate in mating and reproduction, but their role in spatial declarative memory is not understood. Male mice expressed PRs, predominately in excitatory neurons, in brain regions that support spatial memory, such ...

Activity of 3β-hydroxysteroid dehydrogenase associated with progesterone production in bovine granulosa cells cultured under different concentrations of serum, insulin-like growth factor I, and gonadotropin [PDF]

open access: yes, 2014
Three-β-hydroxysteroid dehydrogenase (3β-HSD) is the enzyme responsible for progesterone production. This study aimed to determine whether 3β-HSD activity can be shown to reflect progesterone production by granulosa cells cultured under different serum

Effect of hyperthyroidism on circulating prolactin and hypothalamic expression of tyrosine hydroxylase, prolactin signaling cascade members and estrogen and progesterone receptors during late pregnancy and lactation in the rat [PDF]

open access: yes, 2017
Hyperthyroidism (HyperT) compromises pregnancy and lactation, hindering suckling-induced PRL release. We studied the effect of HyperT on hypothalamic mRNA (RT-qPCR) and protein (Western blot) expression of tyrosine hydroxylase (TH), PRL receptor (PRLR ...

Estrogen and Progesterone Receptors in the Endometrium

open access: yesAnnals of the New York Academy of Sciences, 1997
The endometrium, as a target of estrogens and progestins, possesses the respective receptor proteins. These receptors belong to the superfamily of nuclear receptors, having important functional domains required for steroid ligand binding, for dimer formation, for interaction with HREs of DNA, for transcription modulation, for association with other ...

Immunohistochemical studies of the uterine wall in bitches with different states of the reproductive system [PDF]

open access: yesBIO Web of Conferences
Dysfunctions of the reproductive system in bitches are a severe problem. Studies were conducted to understand the main differences in the receptor activity of immunocompetent cells in the different conditions of the reproductive system to determine the ...

The value of the expression of endometrial receptors for steroid hormones in patients with endometriosis

open access: yesJournal of Education, Health and Sport, 2020
Aim: To elucidate the nature of the expression of progesterone receptors (PR) and estrogen receptors (ER) of the endometrium in patients with endometriosis in order to study the effect of endometriosis therapy on endometrial receptors while taking ...

Estrous behavior in dairy cows: identification of underlying mechanisms and gene functions [PDF]

open access: yes, 2010
Selection in dairy cattle for a higher milk yield has coincided with declined fertility. One of the factors is reduced expression of estrous behavior. Changes in systems that regulate the estrous behavior could be manifested by altered gene expression ...

Temporal changes in the expression of the translocator protein TSPO and the steroidogenic enzyme 5a-reductase in the dorsal spinal cord of animals with neuropathic pain: effects of progesterone administration [PDF]

open access: yes, 2016
Neuropathic pain is a frequent complication of spinal cord injury (SCI), still refractory to conventional treatment. The presence and biological activity of steroidogenic regulatory proteins and enzymes in the spinal cord suggests that neurosteroids ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Unique expression patterns of the embryonal stem cell marker SOX2 and hormone receptors suggest the existence of a subpopulation of epithelial stem/progenitor cells in porcine and bovine endometrium

open access: yesVeterinary Medicine and Science, 2022
Background There are currently insufficient data on the population of endometrial epithelial stem/progenitor cells in farm animals. Objectives With the aim of identifying a potential population of epithelial stem/progenitor cells in the porcine and ...
