Fatty acid stimulation of membrane phosphatidylinositol hydrolysis by brain phosphatidylinositol phosphodiesterase [PDF]

open access: yesBiochemical Journal, 1979
The hydrolysis of membrane-bound phosphatidylinositol in rat liver microsomal fraction by the soluble phosphatidylinositol phosphodiesterase from rat brain was markedly stimulated by oleic acid or arachidonic acid. The stimulation did not require added calcium, although it was abolished by EDTA.

Phosphatidylinositol synthesis at the endoplasmic reticulum [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2020
Phosphatidylinositol (PI) is a minor phospholipid with a characteristic fatty acid profile; it is highly enriched in stearic acid at the sn-1 position and arachidonic acid at the sn-2 position. PI is phosphorylated into seven specific derivatives, and individual species are involved in a vast array of cellular functions including signalling, membrane ...

Exchange of phospholipid classes between liver microsomes and plasma: comparison of rat, rabbit, and guinea pig

open access: yesJournal of Lipid Research, 1971
Rat and guinea pig liver microsomes labeled with phospholipid 32P were incubated with rat, guinea pig, and rabbit plasma in a KC1–Tris–EDTA buffer. A net transfer of microsomal phosphatidylcholine and phosphatidylethanolamine to plasma was observed.

Phosphatidylinositol synthase and phosphatidylinositol/inositol exchange reactions in turkey erythrocyte membranes [PDF]

open access: yesBiochemical Journal, 1991
Unlike human erythrocytes, those from avian species, such as turkeys and chicks, rapidly incorporate myo-[3H]inositol into membrane phospholipids. The mechanisms regulating [3H]Ins labelling of phosphatidylinositol have been investigated using turkey erythrocyte membranes.

Phosphatidylinositol-linked glycans and phosphatidylinositol-anchored proteins of Tetrahymena mimbres

open access: yesJournal of Biological Chemistry, 1991
The insoluble residue from Tetrahymena mimbres cells that had been preincubated in vivo for 2 h with [3H]myristic acid and then exhaustively delipidated with organic solvents retained radioactivity, principally in material which migrated on sodium dodecyl sulfate-polyacrylamide gel electrophoresis with an apparent molecular mass of 10-14 kDa.

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa

open access: yesFEBS Letters, EarlyView.
Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

Quantification of major classes of Xenopus phospholipids by high performance liquid chromatography with evaporative light scattering detection

open access: yesJournal of Lipid Research, 2000
Lipid signaling has become a major research area of cell biology and there is a need for methods that accurately and easily measure substrates and products of lipases involved in cell signaling.

Phosphatidylinositol 4-phosphate and phosphatidylinositol 3-phosphate regulate phagolysosome biogenesis [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
Significance Phagocytes are key to innate immunity, as they ingest, kill, and degrade foreign particles, such as microbes. Particle uptake results in the formation of phagosomes that eventually fuse with lysosomes, the main degradative compartments in cells.

ERBIN limits epithelial cell plasticity via suppression of TGF‐β signaling

open access: yesFEBS Letters, EarlyView.
In breast and lung cancer patients, low ERBIN expression correlates with poor clinical outcomes. Here, we show that ERBIN inhibits TGF‐β‐induced epithelial‐to‐mesenchymal transition in NMuMG breast and A549 lung adenocarcinoma cell lines. ERBIN suppresses TGF‐β/SMAD signaling and reduces TGF‐β‐induced ERK phosphorylation.

Serum phospholipids during aging: A comprehensive systematic review of cross-sectional and case-control studies [PDF]

open access: yesHealth Promotion Perspectives
Background: The lipidome, as a subset of metabolomics, can undergo significant variations due to several factors, including the aging process. Therefore, this study aims to summarize the relationship between aging and alterations in plasma phospholipids.
