Prostaglandin pathways in equine myometrium regulations: endometrosis progression [PDF]
IntroductionProstaglandins (PG) are important regulators of the myometrial contractility in mammals. Endometrosis, a condition characterized by morphological changes in the equine endometrium, also affects endometrial secretory function.

Prostaglandin Endoperoxide H Synthases [PDF]
The cyclooxygenase (COX) activity of prostaglandin endoperoxide H synthases (PGHSs) converts arachidonic acid and O2 to prostaglandin G2 (PGG2). PGHS peroxidase (POX) activity reduces PGG2 to PGH2. The first step in POX catalysis is formation of an oxyferryl heme radical cation (Compound I), which undergoes intramolecular electron transfer forming ...

Prostaglandin endoperoxide synthase contains an EGF‐like domain [PDF]
Prostaglandin endoperoxide synthase was subjected to the computer‐assisted homology search in the protein primary structure database, in order to investigate the regulation mechanism of the expression of prostaglandin endoperoxide synthase. As a result of that, it turned out that prostaglandin endoperoxide synthase shares sequence homology with ...

The orientation of prostaglandin endoperoxide synthases-1 and -2 in the endoplasmic reticulum.
Prostaglandin endoperoxide H synthases (PGHS)-1 and -2 are integral membrane proteins of the endoplasmic reticulum (ER). The luminal versus cytoplasmic orientations of several epitopes of PGHS-1 and PGHS-2 were determined by immunocytofluorescent staining of cells following treatment with membrane-selective permeants.

Unraveling the Mechanism of Xiaochaihu Granules in Alleviating Yeast-Induced Fever Based on Network Analysis and Experimental Validation [PDF]
Xiaochaihu granules (XCHG) are extensively used to treat fever. Nevertheless, the underlying mechanism remains elusive. This study aimed to explore the potential of XCHG in mitigating yeast-induced fever and the underlying metabolic pathways.

Topography of the Prostaglandin Endoperoxide H2 Synthase-2 in Membranes [PDF]
The topology of association of the monotopic protein cyclooxygenase-2 (COX-2) with membranes has been examined using EPR spectroscopy of spin-labeled recombinant human COX-2. Twenty-four mutants, each containing a single free cysteine substituted for an amino acid in the COX-2 membrane binding domain were expressed using the baculovirus system and ...
