A neuronal relay mediates a nutrient responsive gut/fat body axis regulating energy homeostasis in adult Drosophila [PDF]

open access: yes, 2019
The control of systemic metabolic homeostasis involves complex inter-tissue programs that coordinate energy production, storage, and consumption, to maintain organismal fitness upon environmental challenges.

Lipid phosphate phosphatases and signaling

open access: yesJournal of Lipid Research, 2009
Lipid phosphate phosphatases (LPPs) regulate cell signaling by modifying the concentrations of lipid phosphates versus their dephosphorylated products. The ecto-activity regulates the availability of extracellular lysophosphatidate (LPA) and sphingosine 1-phosphate (S1P) and thereby signaling by their respective receptors.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Novel endogenous N-acyl amides activate TRPV1-4 receptors, BV-2 microglia, and are regulated in brain in an acute model of inflammation

open access: yesFrontiers in Cellular Neuroscience, 2014
A family of endogenous lipids, structurally analogous to the endogenous cannabinoid, N-arachidonoyl ethanolamine (Anandamide), and called N-acyl amides have emerged as a family of biologically active compounds at TRP receptors.

A live-cell ergosterol reporter for visualization of the effects of fluconazole on the human fungal pathogen Candida albicans

open access: yesmBio, 2023
Ergosterol, an essential plasma membrane amphipathic lipid, is a major component of the fungal plasma membrane. Most fungal pathogens are susceptible to azole drugs that target ergosterol biosynthesis, and resistance/tolerance to azoles is increasingly ...

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Regulation of podocyte survival and endoplasmic reticulum stress by fatty acids and its modification by Stearoyl-CoA desaturases and cyclic AMP [PDF]

open access: yes, 2011
Podocyte apoptosis is a hallmark in the development and progression of diabetic nephropathy (DN). Several factors of the diabetic milieu are known to induce podocyte apoptosis. Currently, the role of free fatty acids (FFAs) for podocytopathy and podocyte

Nuclear lipid signalling Symposium

open access: yesEuropean Journal of Histochemistry, 2009
Since 46 years ago, when Hokin and Hokin presented the first evidence of an enhanced incorporation of [32P] orthophosphate only into phosphatidylinositol (PI) after stimulation of tissue slices with acetylcholine, the biological role of phospholipids has been confined to the structural organisation of cellular membranes. Stemming from this pionieristic

Lipid Signaling in Pathogenic Fungi [PDF]

open access: yesAnnual Review of Microbiology, 2009
Lipid signaling in pathogenic fungi has been studied to determine the role of these pathways in fungal biology and human infections. Owing to their unique nature, they may represent targets for future antifungal treatments. Farnesol signaling was characterized as a quorum-sensing molecule, with exposure inhibiting filamentation.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
