Molecular Mechanisms Regulating the DNA Repair Protein APE1: A Focus on Its Flexible N-Terminal Tail Domain
(MDPI, 2021-06-11)
APE1 (DNA (apurinic/apyrimidinic site) endonuclease 1) is a key enzyme of one of the major DNA repair routes, the BER (base excision repair) pathway. APE1 fulfils additional functions, acting as a redox regulator of ...
Membrane lipid modifications and therapeutic effects mediated by hydroxydocosahexaenoic acid on Alzheimer's disease
(Elsevier, 2013-12-27)
[EN] Alzheimer's disease (AD) is a neurodegenerative pathology with relevant unmet therapeutic needs. Both natural aging and AD have been associated with a significant decline in the omega-3 polyunsaturated fatty acid ...
Ceramide-enriched membrane domains in red blood cells and the mechanism of sphingomyelinase-induced hot-cold haemolysis
(American Chemical Society, 2008-10-28)
Hot-cold hemolysis is the phenomenon whereby red blood cells, preincubated at 37 °C in
the presence of certain agents, undergo rapid hemolysis when transferred to 4 °C. The mechanism of this
phenomenon is not understood. ...
Changes in Membrane Organization upon Spontaneous Insertion of 2‑Hydroxylated Unsaturated Fatty Acids in the Lipid Bilayer
(American Chemical Society, 2014-02-03)
Recent research regarding 2-hydroxylated fatty acids (2OHFAs) showed clear evidence of their benefits in the treatment of cancer, inflammation, and neurodegenerative disorders such as Alzheimer’s disease. Monolayer ...
G protein-membrane interactions II: Effect of G Protein-linked Lipids on Membrane Structure and G Protein-membrane Interactions
(Elsevier, 2017-07-03)
[EN] G proteins often bear myristoyl, palmitoyl and isoprenyl moieties, which favor their
association with the membrane and their accumulation in G Protein Coupled Receptor-rich
microdomains. These lipids influence the ...
Imaging the early stages of phospholipase C/sphingomyelinase activity on vesicles containing coexisting order-disorder and gel-fluid domains
(Elsevier, 2011-04)
[EN] The binding and early stages of activity of a phospholipase C/sphingomyelinase from Pseudomonas aeruginosa on giant unilamellar vesicles (GUV) have been monitored using fl uorescence confocal microscopy. Both the ...
The triacylglycerol, hydroxytriolein, inhibits triple negative mammary breast cancer cell proliferation through a mechanism dependent on dihydroceramide and Akt
(Impact Journals, 2019-04-02)
The plasma membrane is an attractive target for new anticancer drugs, not
least because regulating its lipid structure can control multiple signaling pathways
involved in cancer cell proliferation, differentiation and ...
Accumulated Bending Energy Elicits Neutral Sphingomyelinase Activity in Human Red Blood Cells
(Elservier, 2012-05-02)
[EN] We propose that accumulated membrane bending energy elicits a neutral sphingomyelinase (SMase) activity in human erythrocytes. Membrane bending was achieved by osmotic or chemical processes, and SMase activity was ...
The effect of hydroxylated fatty acid-containing phospholipids in the remodeling of lipid membranes
(Elsevier B.V., 2014-01-24)
The synthetic fatty acid 2-hydroxyoleic acid (2OHOA) is an antitumor drug that regulates membrane lipid composition and structure. An important effect of this drug is the restoration of sphingomyelin (SM) levels in cancer ...
Conformational stabilization as a strategy to prevent nucleophosmin mislocalization in leukemia
(Nature Research, 2017-10-24)
Nucleophosmin (NPM) is a nucleolar protein involved in ribosome assembly and cell homeostasis. Mutations in the C-terminal domain of NPM that impair native folding and localization are associated with acute myeloid leukemia ...
