Prostanoid Signaling in Cancers: Expression and Regulation Patterns of Enzymes and Receptors

open access: yesBiology, 2022
Cancer-associated disturbance of prostanoid signaling provides an aberrant accumulation of prostanoids. This signaling consists of 19 target genes, encoding metabolic enzymes and G-protein-coupled receptors, and prostanoids (prostacyclin, thromboxane ...

Trypanosoma cruzi infection and endothelin-1 cooperatively activate pathogenic inflammatory pathways in cardiomyocytes. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2013
Trypanosoma cruzi, the causative agent of Chagas' disease, induces multiple responses in the heart, a critical organ of infection and pathology in the host.

Modeling of biological doses and mechanical effects on bone transduction [PDF]

open access: yesJournal of Theoretical Biology 274, 1 (2011) 36-42, 2011
Shear stress, hormones like parathyroid and mineral elements like calcium mediate the amplitude of stimulus signal which affects the rate of bone remodeling. The current study investigates the theoretical effects of different metabolic doses in stimulus signal level on bone.

Aldo-keto reductases 1B in adrenal cortex physiology

open access: yesFrontiers in Endocrinology, 2016
Aldose reductase proteins are cytosolic monomeric enzymes, belonging to the aldo-keto reductase (AKR) superfamily. They perform oxidoreduction of carbonyl groups from a wide variety of substrates such as aliphatic and aromatic aldehydes or ketones.

The physiological basis with uterine myometrium contractions from electro-mechanical/hormonal myofibril function to the term and preterm labor

open access: yesHeliyon, 2023
Background: Most labor-related problems can be attributed to the uterine myometrium muscle, as this irritable tissue must suppress its irritability potential during pregnancy.

Aldo keto reductase 1B7 and prostaglandin F2alpha are regulators of adrenal endocrine functions. [PDF]

open access: yesPLoS ONE, 2009
Prostaglandin F(2alpha) (PGF(2alpha)), represses ovarian steroidogenesis and initiates parturition in mammals but its impact on adrenal gland is unknown.

2-(4-Methylsulfonylphenyl)pyrimidines as Prospective Radioligands for Imaging Cyclooxygenase-2 with PET—Synthesis, Triage, and Radiolabeling

open access: yesMolecules, 2018
Cyclooxygenase 2 (COX-2) is an inducible enzyme responsible for the conversion of arachidonic acid into the prostaglandins, PGG2 and PGH2. Expression of this enzyme increases in inflammation.

Ixodes ricinus tick lipocalins: identification, cloning, phylogenetic analysis and biochemical characterization. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: During their blood meal, ticks secrete a wide variety of proteins that interfere with their host's defense mechanisms. Among these proteins, lipocalins play a major role in the modulation of the inflammatory response.

Effects of arachidonic acid supplementation in maturation diet on female reproductive performance and larval quality of giant river prawn (Macrobrachium rosenbergii) [PDF]

open access: yesPeerJ, 2016
The giant river prawn (Macrobrachium rosenbergii) is one of the most farmed freshwater crustaceans in the world. Its global production has been stalling in the past decade due to the inconsistent quality of broodstock and hatchery-produced seeds.

Increased cyclooxygenase-2-derived prostanoids contributes to the hyperreactivity to noradrenaline in mesenteric resistance arteries from offspring of diabetic rats. [PDF]

open access: yesPLoS ONE, 2012
This study analyzed the effect of in utero exposure to maternal diabetes on contraction to noradrenaline in mesenteric resistance arteries (MRA) from adult offspring, focusing on the role of cyclooxygenase (COX)-derived prostanoids.
