Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Analysis of Jmjd6 cellular localization and testing for its involvement in histone demethylation. [PDF]

, 2010
Methylation of residues in histone tails is part of a network that regulates gene expression. JmjC domain containing proteins catalyze the oxidative removal of methyl groups on histone lysine residues.

Phosphatidylserine-dependent structure of synaptogyrin remodels the synaptic vesicle membrane [PDF]

, 2023
Synaptic vesicles are small membrane-enclosed organelles that store neurotransmitters at presynaptic terminals. The uniform morphology of synaptic vesicles is important for brain function, because it enables the storage of well-defined amounts of ...

Induction of Suicidal Erythrocyte Death by Nelfinavir

Toxins, 2015
The HIV protease inhibitor, nelfinavir, primarily used for the treatment of HIV infections, has later been shown to be effective in various infectious diseases including malaria. Nelfinavir may trigger mitochondria-independent cell death.

The effect of addition protein, phosphatidylcholine, phosphatidylserine, and inulin on GFAP levels of acute ischemic stroke patients at Dr. Kariadi Hospital, Semarang

Jurnal Gizi Indonesia: The Indonesian Journal of Nutrition, 2021
Background: The occurrence of ischemia causes a loss of energy to switch to anaerobic processes resulting in acidosis due to reduced Adenosina Triphosphate (ATP). This condition makes neuron cells apoptotic. Apoptotic of several biochemical substrates in

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Role of Phosphatidylserine Receptors in Enveloped Virus Infection [PDF]

, 2014
We recently demonstrated that a soluble protein, Gas6, can facilitate viral entry by bridging viral envelope phosphatidylserine to Axl, a receptor tyrosine kinase expressed on target cells.

Stimulation of Erythrocyte Cell Membrane Scrambling by Mushroom Tyrosinase

Toxins, 2014
Background: Mushroom tyrosinase, a copper containing enzyme, modifies growth and survival of tumor cells. Mushroom tyrosinase may foster apoptosis, an effect in part due to interference with mitochondrial function.

Ex Vivo Activation of Red Blood Cell Senescence by Plasma from Sickle-Cell Disease Patients: Correlation between Markers and Adhesion Consequences during Acute Disease Events

Biomolecules, 2021
BACKGROUND: Blood transfusion remains a key treatment for managing occlusive episodes and painful crises in sickle-cell disease (SCD). In that clinical context, red blood cells (RBCs) from donors and transfused to patients, may be affected by plasma ...

Characterization of Phosphatidylserine Transport to the Locus of Phosphatidylserine Decarboxylase 2 in Permeabilized Yeast [PDF]

Journal of Biological Chemistry, 2001
In yeast, nascent phosphatidylserine (PtdSer) can be transported to the mitochondria and Golgi/vacuole for decarboxylation to synthesize phosphatidylethanolamine (PtdEtn). In strains with a psd1Delta allele for the mitochondrial PtdSer decarboxylase, the conversion of nascent PtdSer to PtdEtn can serve as an indicator of lipid transport to the locus of
