Mutational and X-ray Crystallographic Analysis of the Interaction of Dihomo-γ-linolenic Acid with Prostaglandin Endoperoxide H Synthases

open access: hybridJournal of Biological Chemistry, 2001
Prostaglandin endoperoxide H synthases-1 and -2 (PGHSs) catalyze the committed step in prostaglandin biosynthesis. Both isozymes can oxygenate a variety of related polyunsaturated fatty acids.

Structure of Eicosapentaenoic and Linoleic Acids in the Cyclooxygenase Site of Prostaglandin Endoperoxide H Synthase-1 [PDF]

open access: hybridJournal of Biological Chemistry, 2001
Prostaglandin endoperoxide H synthases-1 and -2 (PGHSs) can oxygenate 18–22 carbon polyunsaturated fatty acids, albeit with varying efficiencies. Here we report the crystal structures of eicosapentaenoic acid (EPA, 20:5 n-3) and linoleic acid (LA, 18:2 n-

The Expression Pattern of Prostaglandin-Endoperoxide Synthase-2 in Immature Oocytes and Surrounding Cumulus Cells May Explain A Disrupted Oocyte Maturation Process

open access: yesGynecology Obstetrics & Reproductive Medicine, 2021
Objective: To evaluate the correlation between the gene expression of prostaglandin-endoperoxide synthase-2 in the cumulus-oocyte complex with the level of prostaglandin-endoperoxide synthase-2 in follicular fluid and follicle diameter, oocyte ...

ATP Synthase: A Moonlighting Enzyme with Unprecedented Functions [PDF]

open access: yesChem. Commun., 2022, 58, 2650-2653, 2021
ATP synthase's intrinsic molecular electrostatic potential (MESP) adds constructively to, and hence reinforces, the chemiosmotic voltage. This ATP synthase voltage represents a new free energy term that appears to have been overlooked. This term is at least roughly equal in order of magnitude and opposite in sign to the energy needed to be dissipated ...

Exosomes and their roles in the chemoresistance of pancreatic cancer

open access: yesCancer Medicine, Volume 11, Issue 24, Page 4979-4988, December 2022., 2022
Despite the development of multiple promising chemotherapeutic agents as recommended first‐line treatment for PC, the therapeutic efficacy is largely limited by unwanted drug resistance.Exploring the relation between exosomes and chemoresistance may be conducive to understanding molecular mechanisms and taking effective measures to reduce the ...

Cyclooxygenase-2 expression in cervical cancer [PDF]

open access: yesVojnosanitetski Pregled, 2014
Background/Aim. Cyclooxygenase (COX) or prostaglandin H2 synthase is the first enzyme that catalyzes the first two steps in the biosynthesis of prostaglandins from arachidonic acid.

Emergence of highly profibrotic and proinflammatory Lrat+Fbln2+ HSC subpopulation in alcoholic hepatitis

open access: yesHepatology, EarlyView., 2022
Lrat+ quiescent hepatic stellate cells (qHSC) give rise to Lrat+Fbln2+ activated HSC (aHSC) in alcohol‐associated hepatitis and this subpopulation is highly profibrotic, inflammatory, and immunoregulatory based on their single cell transcriptomic profile. Abstract Background and Aims Relative roles of HSCs and portal fibroblasts in alcoholic hepatitis (

Dynamic regulation of the transcriptome and proteome of the equine embryo during maternal recognition of pregnancy

open access: yesFASEB BioAdvances, Volume 4, Issue 12, Page 775-797, December 2022., 2022
Abstract During initial maternal recognition of pregnancy (MRP), the equine embryo displays a series of unique events characterized by rapid blastocyst expansion, secretion of a diverse array of molecules, and transuterine migration to interact with the uterine surface.
