Reactions of Prostaglandin Endoperoxide Synthase and Its Compound I with Hydroperoxides [PDF]

Journal of Biological Chemistry, 1996
The reactions of native prostaglandin endoperoxide synthase with structurally different hydroperoxides have been investigated by using kinetic spectrophotometric scan and conventional and sequential mixing stopped-flow experiments. The second order rate constants for compound I formation are (5.9 +/- 0.1) x 10(4) M-1 s-1 using t-butyl hydroperoxide as ...

Bioinformatics analysis of immune‐programmed cell death‐related genes in nasopharyngeal carcinoma

Eye &ENT Research, EarlyView.
Abstract Background Nasopharyngeal carcinoma (NPC) is a prevalent malignant tumor of the head and neck, characterized by a complex pathogenesis. Most newly diagnosed NPC patients are locally advanced, and 20%–30% of advanced NPC patients have poor immunotherapy results.

Uric Acid‐Lowering and Anti‐Hyperuricemia Effects of Plant‐Based Nutraceuticals and Foods: A Review

Food Chemistry International, EarlyView.
Increased UA production and/or decreased UA secretion cause hyperuricemia. Effects and mechanism of flavonoids in reducing UA are summarized. Terpenoids, saponins, alkaloids, vitamin C, polysaccharides, peptides are effective. Plant‐based foods with UA‐lowering ability are reviewed.

Flipping the cyclooxygenase (Ptgs) genes reveals isoform-specific compensatory functions1,2[S]

Journal of Lipid Research, 2018
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.

Pharmacological effects of gastrodin: Insight into neurological diseases and mechanism in ferroptosis and pyroptosis

Ibrain, Volume 11, Issue 1, Page 74-83, Spring 2025.
Pharmacological effects of gastrodin include prevention and treatment of cognitive decline and reperfusion injuries, anticonvulsion, antiepilepsy, antidepressants, and analgesia, which are related to antiferroptosis and antipyroptosis. Abstract Gastrodin, as an effective monomer of gastrodia elata, plays a significant role in anti‐inflammatory ...

Aging Adipose‐Derived Mesenchymal Stem Cells, Cultured on a Native Young Extracellular Matrix, Are Protected From Senescence and Apoptosis Along With Increased Expression of HLA‐DR and CD74 Associated With PI3K Signaling

Aging Cell, EarlyView.
The maintenance of aging mesenchymal stem cells (MSCs) on extracellular matrix synthesized by human amniotic fluid‐derived pluripotent stem cells (ECM Plus), a young microenvironment, remarkably restored their quantity and quality along with up‐regulating HLA‐DR and CD74.

Thirty Years of Autologous Platelet Concentrates: From Platelet‐Rich Plasma to Platelet‐Rich Fibrin

Journal of Periodontal Research, EarlyView.
ABSTRACT Nearly three decades have now passed since autologous platelet concentrates (APCs) were introduced into clinical practice. Harnessing the body's innate intrinsic capacity for healing, the concepts of platelet‐rich plasma (PRP) and platelet‐rich fibrin (PRF) emerged to concentrate growth factors and cells at supra‐physiological levels.

Mitochondria ATP Pro‐Ferroptosis by Adjusting the Conversion of PUFA to PUFA‐PLs

MedComm – Oncology, Volume 4, Issue 3, September 2025.
Glutamine deprivation can promote PUFA oxidation and PTGS2 expression through the upregulation of intracellular ROS, but not ferroptosis. Because glutamine deficiency exhausts mitochondrial ATP, thereby hinders the conversion of PUFA into their active form of PUFA‐CoA needed for lipid synthesis.
