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.

Cyclopentenone Prostaglandins of the J Series Inhibit the Ubiquitin Isopeptidase Activity of the Proteasome Pathway*

open access: yesJournal of Biological Chemistry, 2001
Electrophilic eicosanoids of the J series, with their distinctive cross-conjugated α,β-unsaturated ketone, inactivate genetically wild type tumor suppressor p53 in a manner analogous to prostaglandins of the A series.

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.

Inactivation of wild-type p53 tumor suppressor by electrophilic prostaglandins.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2000
The electrophilic eicosanoids prostaglandins A(1) or A(2) impaired p53-dependent transcription of endogenous genes and exogenous p53-luciferase reporter plasmids in RKO and HCT 116 colon cancer cells.

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.

Preparation of Prostaglandin F from Prostaglandin E. Prostaglandins and Related Factors. 6. [PDF]

open access: yesActa Chemica Scandinavica, 1962
Reduction of prostaglandin E (PGE) with sodium borohydride yielded 2 compounds 1 of which is identical with PGF isolated from the prostate of sheep and the other of which had different physical and biological properties but the same elementary composition. The former was designated PGF1 and the latter PGF2.

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.

Endogenous prostaglandins in peptic ulcer disease.

open access: yesGut, 1979
Plasma concentrations of prostaglandins E and F have been measured by radioimmunoassay in patients undergoing diagnostic upper intestinal endoscopy. The results fail to support a previously reported deficiency of plasma PGE in duodenal ulcer patients ...

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.
