The role of human cytochrome P450 2E1 in liver inflammation and fibrosis. [PDF]

open access: yes, 2017
Cytochrome P450 2E1 (CYP2E1) plays an important role in alcohol and toxin metabolism by catalyzing the conversion of substrates into more polar metabolites and producing reactive oxygen species.

Opposing roles of DGAT‐mediated lipid droplet biogenesis in the regulation of ferroptosis sensitivity

open access: yesThe FEBS Journal, EarlyView.
Ferroptosis is driven by unrestricted peroxidation of polyunsaturated fatty acyl (PUFA) chains in membrane phospholipids. In triple‐negative breast cancer cells, lipid droplets (LDs) sequester dietary PUFAs, limiting their incorporation into membrane phospholipids, preventing mitochondrial damage, and reducing lipid peroxidation and ferroptosis.

Evaluation of Cysteinyl Leukotriene Signaling as a Therapeutic Target for Colorectal Cancer

open access: yesFrontiers in Cell and Developmental Biology, 2016
Colorectal cancer is the third most common cancer worldwide and is associated with significant morbidity and mortality. Current pharmacotherapy options include cytotoxic chemotherapy, anti-VEGF and anti-EGFR targeting drugs, but these are limited by ...

Steroidogenic compensation and lipid deficiency with enhanced NAD+ salvage in small‐for‐gestational‐age placenta

open access: yesThe FEBS Journal, EarlyView.
Fetal growth restriction is associated with placental metabolic adaptations. In small‐for‐gestational‐age placenta (SGA), cholesterol receptors and steroidogenic enzymes are upregulated, enhancing steroidogenesis. NAD salvage pathway is also increased to support NADP+/NADPH requirements.

Eicosapentaenoic acid induces DNA demethylation in carcinoma cells through a TET1-dependent mechanism [PDF]

open access: yes, 2018
In cancer cells, global genomic hypomethylation is found together with localized hypermethylation of CpG islands within the promoters and regulatory regions of silenced tumor suppressor genes.

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

open access: yesThe FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

Evaluation of the performance of ChatGPT‐4 and ChatGPT‐4o as a learning tool in endodontics

open access: yesInternational Endodontic Journal, EarlyView.
Abstract Aims The aim of this study was to evaluate the accuracy and consistency of responses given by two different versions of Chat Generative Pre‐trained Transformer (ChatGPT), ChatGPT‐4, and ChatGPT‐4o, to multiple‐choice questions prepared from undergraduate endodontic education topics at different times of the day and on different days ...

Dietary chia seed (Salvia hispanica L.) rich in a-linolenic acid improves adiposity and normalises hypertriacylglycerolaemia and insulin resistance in dyslipaemic rats [PDF]

open access: yes, 2009
The present study investigates the benefits of the dietary intake of chia seed (Salvia hispanica L.) rich in α-linolenic acid and fibre upon dyslipidaemia and insulin resistance (IR), induced by intake of a sucrose-rich (62.5 %) diet (SRD).

Larval Arctic cod (Boreogadus saida) exhibit stronger developmental and physiological responses to temperature than to elevated pCO2

open access: yesJournal of Fish Biology, EarlyView.
Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Inflammatory Resolution Triggers a Prolonged Phase of Immune Suppression through COX-1/mPGES-1-Derived Prostaglandin E2

open access: yesCell Reports, 2017
Acute inflammation is characterized by granulocyte infiltration followed by efferocytosing mononuclear phagocytes, which pave the way for inflammatory resolution.
