Characterization and ligand identification of a membrane progesterone receptor in fungi: existence of a novel PAQR in Sporothrix schenckii

open access: yesBMC Microbiology, 2012
Background Adaptive responses in fungi result from the interaction of membrane receptors and extracellular ligands. Many different classes of receptors have been described in eukaryotic cells. Recently a new family of receptors classified as belonging to

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 ...

N-glycans of human amniotic fluid transferrin stimulate progesterone production in human first trimester trophoblast cells in vitro [PDF]

open access: yes, 2004
Aims: During pregnancy, the placenta produces a variety of steroid hormones and proteins. Several of these substances have been shown to exert immunomodulatory effects.

Non-genomic mechanisms of progesterone action in the brain

open access: yesFrontiers in Neuroscience, 2013
Progesterone is a gonadal steroid hormone whose physiological effects extend well beyond the strict confines of reproductive function. In fact, progesterone can have important effects on a variety of tissues, including the bone, the heart and the brain ...

Effect of oxytocin on free intracellular Ca2+ levels and progesterone release by human granulosa-lutein cells [PDF]

open access: yes, 1993
Oxytocin and its receptor are found in the corpus luteum in a variety of species, including the human. In the present study we used fura-2 microfluorimetry to investigate whether activation of the oxytocin receptor of cultured human granulosa-lutein ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

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 ...

Concerted action of human chorionic gonadotropin and norepinephrine on intracellular-free calcium in human granulosa-lutein cells [PDF]

open access: yes, 1993
Luteal cells are known to possess receptors for LH/hCG and receptors of the beta-adrenergic type. Interactions of specific agonists with either receptor lead to the activation of adenylate cyclase and subsequently to an increase of cAMP.
