METHOD FOR MODULATING EICOSANOID MEDIATED IMMUNE RESPONSES IN ARTHROPODS [PDF]
The invention is directed to compositions which alter the health of invertebrate organisms by affecting eicosanoid mediated immune responses, and methods of using the compositions.

Effect of Cyclooxygenase(COX)-1 and COX-2 inhibition on furosemide-induced renal responses and isoform immunolocalization in the healthy cat kidney [PDF]
BACKGROUND: The role of cyclooxygenase(COX)-1 and COX-2 in the saluretic and renin-angiotensin responses to loop diuretics in the cat is unknown. We propose in vivo characterisation of isoform roles in a furosemide model by administering non-steroidal ...

Flipping the cyclooxygenase (Ptgs) genes reveals isoform-specific compensatory functions1,2[S]
Two prostaglandin (PG) H synthases encoded by Ptgs genes, colloquially known as cyclooxygenase (COX)-1 and COX-2, catalyze the formation of PG endoperoxide H2, the precursor of the major prostanoids.

High eosinophil (EOS) counts are a key feature of eosinophilic asthma. EOS notably affect asthmatic response by generating several lipid mediators. Mice have been utilized in hopes of defining new pharmacological targets to treat asthma.

This study identifies Pirin (PIR), an iron‐binding protein, as a critical ferroptosis suppressor in colorectal cancer through lipid membrane remodeling. PIR, induced by NRF2 during ferroptotic stress, transcriptionally regulates PLA2G4A to shift cellular lipid composition away from ferroptosis‐permissive polyunsaturated phospholipids.

Cholesterol-sensing liver X receptors stimulate Th2-driven allergic eosinophilic asthma in mice [PDF]
Introduction: Liver X receptors (LXRs) are nuclear receptors that function as cholesterol sensors and regulate cholesterol homeostasis. High cholesterol has been recognized as a risk factor in asthma; however, the mechanism of this linkage is not known.

Both cyclooxygenase (COX)-1 and COX-2, encoded by Ptgs1 and Ptgs2, function coordinately during inflammation. But the relative contributions and compensations of COX-1 and COX-2 to inflammatory responses remain unanswered.

BackgroundEicosanoids are a group of the oxygenated C20 polyunsaturated fatty acids and play crucial roles in mediating various insect physiological processes. Catalytic activity of phospholipase A2 (PLA2) provides an initial substrate, arachidonic acid (

This study demonstrates that BNNT exposure disrupts lipid homeostasis in bronchial epithelial cell cultures and activates eicosanoid lipid biosynthesis, producing inflammatory lipid mediators like leukotrienes. These effects are more pronounced in asthmatic cell cultures compared to healthy ones.

Substrate-Specific Inhibition Constants for Phospholipase A2 Acting on Unique Phospholipid Substrates in Mixed Micelles and Membranes Using Lipidomics. [PDF]
Assaying lipolytic enzymes is extremely challenging because they act on water-insoluble lipid substrates, which are normally components of micelles, vesicles, and cellular membranes.
