The importance of an integrated analysis of clinical, molecular, and functional data for the genetic diagnosis of familial hypercholesterolemia
(Nature, 2015-12)
Purpose
Familial hypercholesterolemia (FH) is one of the most common monogenic disorders, and the high concentrations of low-density lipoprotein (LDL) cholesterol presented since birth confers on these patients an increased ...
The T1D-associated lncRNA Lnc13 modulates human pancreatic β cell inflammation by allele-specific stabilization of STAT1 mRNA
(National Academy of Sciences, 2020-03-05)
The vast majority of type 1 diabetes (T1D) genetic association signals lie in non-coding regions of the human genome. Many have been predicted to affect the expression and secondary structure of long non-coding RNAs ...
The three lives of viral fusion peptides
(Elsevier, 2014-04)
Fusion peptides comprise conserved hydrophobic domains absolutely required for the fusogenic activity of glycoproteins from divergent virus families. After 30 years of intensive research efforts, the structures and functions ...
Conjugative Coupling Proteins and the Role of Their Domains in Conjugation, Secondary Structure and in vivo Subcellular Location
(Frontiers Media, 2020-08-11)
Type IV Coupling Proteins (T4CPs) are essential elements in many type IV secretion systems (T4SSs). The members of this family display sequence, length, and domain architecture heterogeneity, being the conserved ...
The Binding of Aβ42 Peptide Monomers to Sphingomyelin/Cholesterol/Ganglioside Bilayers Assayed by Density Gradient Ultracentrifugation
(MDPI, 2020-02-29)
The binding of Aβ42 peptide monomers to sphingomyelin/cholesterol (1:1 mol ratio) bilayers containing 5 mol% gangliosides (either GM1, or GT1b, or a mixture of brain gangliosides) has been assayed by density gradient ...
Exploring Polar Headgroup Interactions Between Sphingomyelin and Ceramide with Infrared Spectroscopy
(Nature, 2020-10-19)
Ceramide is a major actor in the sphingolipid signaling pathway elicited by various kinds of cell stress. Under those conditions ceramide (Cer) is produced in the plasma membrane as a product of sphingomyelin (SM) hydrolysis, ...
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 ...
