Lipid‐protein interactions in membranes [PDF]

FEBS Letters, 1990
The interactions of lipids with integral and peripheral proteins can be studied in reconstituted and natural membranes using spin label electron spin resonance (ESR) spectroscopy. The ESR spectra reveal a reduction in mobility of the spin‐labelled lipid chains on binding of peripheral proteins to negatively‐charged lipid bilayers.

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

Molecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

Surfactant-free purification of membrane protein complexes from bacteria: application to the staphylococcal penicillin-binding protein complex PBP2/PBP2a. [PDF]

, 2014
Surfactant-mediated removal of proteins from biomembranes invariably results in partial or complete loss of function and disassembly of multi-protein complexes. We determined the capacity of styrene-co-maleic acid (SMA) co-polymer to remove components of

Interaction of HS1BP3 with cortactin modulates TKS5 localisation, cell secretion and cancer malignancy

Molecular Oncology, EarlyView.
Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...

The effect of membrane active agents on human leukaemia cells [PDF]

, 1998
This Thesis investigates the effect of membrane-active agents, such as synthetic ether lipids (SEL), local anaesthetics and polyunsaturated fatty acids (PUFAs) on human leukaemia cells.

Protein-lipid interactions: paparazzi hunting for snap-shots

, 2009
Photoactivatable groups meeting the criterion of minimal perturbance allow the investigation of interactions in biological samples. Here, we review the application of photoactivatable groups in lipids enabling the study of protein-lipid interactions in ...

DPD simulation to reproduce lipid membrane microdomains based on fragment molecular orbital calculations

Applied Physics Express
Lipid domains play a critical role in signal transduction and transport across cell membranes. The formation of domains in “HLC” ternary lipid bilayers composed of high transition temperature (high- Tm ) lipids, low- Tm lipids, and cholesterol (Chol) has

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Energetics of lipid bilayers with applications to deformations induced by inclusions

, 2013
A new energy for the description of large deformations of lipid bilayers is formulated with mathematical rigor. This energy is derived by considering the smectic A liquid crystalline nature of lipid bilayers and the coupling between the deformations of ...

Detergent-protein and detergent-lipid interactions : implications for two-dimensional crystallization of membrane proteins and development of tools for high throughput crystallography [PDF]

, 2006
2.1 Scope of this Thesis This thesis represents an attempt to enlighten the role of the detergent in reconstitution and more specifically in two-dimensional (2D) crystallogenesis of membrane proteins. The construction of a tool for precise and routine
