The Pivotal Role of GR‐CAR Pathway in Fetal Programming of Hepatic Cytochrome P450 3A Alteration in Adulthood

open access: yesAdvanced Science, EarlyView.
Prenatal dexamethasone exposure (PDE) persistently upregulates hepatic CYP3A1/CYP2B1 in offspring via glucocorticoid receptor (GR) activation. In vivo and in vitro studies show GR promotes P300/CBP binding to the constitutive androstane receptor (CAR) promoter, sustaining histone acetylation (H3K9/K27ac) and enhancing CYP expression. The GR–CAR pathway

Arachidonic Acid Production by Fungi [PDF]

open access: yesApplied and Environmental Microbiology, 1991
After preliminary screening, Mortierella alpina and Mortierella elongata were compared with respect to arachidonic acid content. M. alpina ATCC 16266 produced 2.1 g of arachidonic acid per liter in media containing 10% glucose while the highest percentage of ...

Inhibitory effect of calotropis gigantea extract on ovalbumin-induced airway inflammation and arachidonic acid induced inflammation in a murine model of asthma [PDF]

open access: yes, 2011
The root of Calotropis gigantea has been reported as a traditional folkloric medicine in treatment of asthma in the Indian literature. Root contain α-and β-amyrin are reported to possess anti-lipoxygenase activity.

Inhibition of Calcium‐Dependent Lipid Droplets Relocation of ACSL4‐PKCβ‐ALOX15 Complex Alleviates Ferroptosis and Acute Pancreatitis

open access: yesAdvanced Science, EarlyView.
This study identifies L‐type calcium channel blockers as novel ferroptosis inhibitors. It reveals that PKCβ, activated in calcium dependent manner, phosphorylates and activates ACSL4 and ALOX15, relocating them to lipid droplets to promote lethal lipid peroxidation and ferroptosis.

Level of Arachidonic Acid and State of Peroxidation Processes in Patients with Aspirin-Intolerant Polypous Rhinosinusitis

open access: yesGalician Medical Journal, 2016
The main peculiarity of aspirin-intolerant polypous rhinosinusitis pathogenesis is the presence of “genetic block” of constitutive cyclooxygenase being the key enzyme of the arachidonic acid metabolism.

Expression of mRNA for phospholipase A(2), cyclooxygenases, and lipoxygenases in cultured human umbilical vascular endothelial and smooth muscle cells and in biopsies from umbilical arteries and veins [PDF]

open access: yes, 1998
Arachidonic acid (AA) is released by phospholipase A(2) (PLA(2)) and then converted into vasoactive and inflammatory eicosanoids by cyclooxygenases (COX) and lipoxygenases (LOX).

Pirin Transcriptionally Regulates PLA2G4A To Inhibit Ferroptosis in Colorectal Cancer via Lipid Profile Remodeling

open access: yesAdvanced Science, EarlyView.
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.

Conversion of eicosapentaenoic acid to chain-shortened omega–3 fatty acid metabolites by peroxisomal oxidation1

open access: yesJournal of Lipid Research, 1998
Human skin fibroblasts can convert arachidonic acid to 14- and 16-carbon polyunsaturated fatty acid products by peroxisomal β-oxidation. The purpose of this study was to determine whether similar products are formed from eicosapentaenoic acid (EPA) and ...
