Lysophosphatidic Acids Induce Contraction of Rat Isolated Colon by Two Different Mechanisms

open access: yes, 1991
Lysophosphatidic acids (1-linoleoyl-, 1-linolenoyl, 1-arachidonoyl- and 1-O-hexadecyl-sn-glycero-3-phosphate) induced rapid contraction of rat isolated colon which was dependent on external Ca2+, 1-linolenoyl-lysophosphatidic acid having the greatest ...

Formation of phosphatidic acid in stressed mitochondria

open access: yesArchives of Biochemistry and Biophysics, 2008
Mitochondria are an important intracellular source of ROS as well as a sensitive target for oxidative damage under certain pathological conditions such as iron or copper overload. Mitochondrial membranes are rich in the tetraacyl phospholipid cardiolipin. Its integrity is important for efficient oxidative phosphorylation.

Putting the pH into phosphatidic acid signaling [PDF]

open access: yesBMC Biology, 2011
Abstract: The lipid phosphatidic acid (PA) has important roles in cell signaling and metabolic regulation in all organisms. New evidence indicates that PA also has an unprecedented role as a pH biosensor, coupling changes in pH to intracellular signaling pathways. pH sensing is a property of the phosphomonoester headgroup of PA.

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.

Biochemistry of ungerminated and germinated spores of the vesicular-arbuscular mycorrhizal fungus, Glomus caledonius: changes in neutral and polar lipids.

open access: yesJournal of Lipid Research, 1980
Neutral and polar spore lipids of the vesicular-arbuscular (VA) endophyte Glomus caledonius, were identified and quantitatively determined during spore germination, germ tube growth, and germ tube senescence.

Pangenome analysis reveals the genetic mechanism underlying high‐altitude adaptation in Qinghai–Xizang (Tibet) Plateau Rhododendron

open access: yesJournal of Integrative Plant Biology, EarlyView.
Pan‐genome analysis reveals that high‐altitude Rhododendron species resist alpine cold stress by rapidly sensing and engaging the chilling response pathway and genes that directly and indirectly protect the plant from UV radiation. Heritable genomic features such as long terminal repeats contribute to the adaptive diversification of Rhododendron ...

Phospholipid metabolism during bacterial growth

open access: yesJournal of Lipid Research, 1969
Haemophiius parainjuenzae incorporates glycerol and phosphate into the membrane phospholipids without lag during logarithmic growth. In phosphatidyl glycerol (PG), the phosphate and unacylated glycerol moieties turn over and incorporate radioactivity ...

Mutants in pathways converging on dicacylglycerol and phosphatidic acid.

open access: yes, 2013
(A) Phenotype of mutants related to triglyceride metabolism under screening conditions. Cells of the indicated mutants were grown and subjected to vacuole fragmentation as in Figure 1. Pictures show an overlay of the fluorescence and brightfield channels.

Decoding MAPK cascades in plant immunity: Activation, regulation, integration, and pathogen manipulation

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review focuses on mitogen‐activated protein kinase (MAPK) activation and summarizes how plants regulate and integrate MAPK signaling in modulating plant immune responses. It also examines the effectors pathogens have evolved to manipulate MAPK activation and thereby inhibit plant immunity.
