Lipid Self-Assemblies under the Atomic Force Microscope
(MDPI, 2021-09-18)
Lipid model membranes are important tools in the study of biophysical processes such as lipid self-assembly and lipid–lipid interactions in cell membranes. The use of model systems to adequate and modulate complexity helps ...
CHO/LY-B Cell Growth under Limiting Sphingolipid Supply: Correlation between Lipid Composition and Biophysical Properties of Sphingolipid-Restricted Cell Membranes
(Wiley, 2021-06)
Sphingolipids (SL) are ubiquitous in mammalian cell membranes, yet there is little data on the behavior of cells under SL- restriction conditions. LY- B cells derive from a CHO linein whichserine palmitoyl transferase ...
Erythrocyte Membrane Nanomechanical Rigidity Is Decreased in Obese Patients
(MDPI, 2022-02-08)
This work intends to describe the physical properties of red blood cell (RBC) membranes in obese adults. The hypothesis driving this research is that obesity, in addition to increasing the amount of body fat, will also ...
Plasma membrane effects of sphingolipid-synthesis inhibition by myriocin in CHO cells: a biophysical and lipidomic study
(Nature Research, 2022)
[EN] Suppression of a specific gene effect can be achieved by genetic as well as chemical methods. Each approach may hide unexpected drawbacks, usually in the form of side effects. In the present study, the specific inhibitor ...
Phase behaviour of C18-N-acyl sphingolipids, the prevalent species in human brain.
(Elsevier, 2022-11)
Lipidomic analysis of the N-acyl components of sphingolipids in different mammalian tissues had revealed that brain tissue differed from all the other samples in that SM contained mainly C18:0 and C24:1N-acyl chains, and ...
Liquid-crystalline, liquid-ordered, rippled and gel lipid bilayer phases as observed with nile red fluorescence
(Elsevier, 2022-10)
The basic matrix of cellular membranes consists of a double layer (bilayer) of phospholipids. Semisynthetic lipid bilayers are commonly used in biophysical studies of membranes. According to tem-perature and composition, ...
LC3 subfamily in cardiolipin-mediated mitophagy: a comparison of the LC3A, LC3B and LC3C homologs
(Taylor & Francis, 2022-12)
Externalization of the phospholipid cardiolipin (CL) to the outer mitochondrial membrane has been proposed to act as a mitophagy trigger. CL would act as a signal for binding the LC3 macroauto-phagy/autophagy proteins. As ...
Patches and Blebs: A Comparative Study of the Composition and Biophysical Properties of Two Plasma Membrane Preparations from CHO Cells
(MDPI, 2020-04-10)
This study was aimed at preparing and characterizing plasma membranes (PM) from Chinese Hamster Ovary (CHO) cells. Two methods of PM preparation were applied, one based on adhering cells to a poly-lysine-coated surface, ...
Nucleophosmin interaction with APE1: Insights into DNA repair regulation
(Elsevier, 2020-01-30)
[EN] Nucleophosmin (NPM1), an abundant, nucleolar protein with multiple functions affecting cell homeostasis, has also been recently involved in DNA damage repair. The roles of NPM1 in different repair pathways remain ...
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 ...
