C‐Terminal Nucleobase Modification Amplifies Peptide‐Mediated Liposome Fusion

Chemistry – A European Journal, EarlyView.
Let's come together right now. Cationic peptides are known to promote aggregation of negatively charged liposomes through electrostatic interaction. The process is reversible: once neutrality is achieved, liposomes disaggregate. Here, we demonstrate that end‐capping peptides with nucleobases turns the process into irreversible fusion.

PHOSPHO1 Suppresses Ferroptosis in Retinal Pigment Epithelial Cells by Reducing the Levels of Phosphatidylethanolamine Molecular Species

Advanced Science
Iron‐induced lipid peroxidation of phosphatidylethanolamine (PE) species is a key driver of ferroptosis in retinal pigment epithelial (RPE) cells, a process closely associated with age‐related macular degeneration (AMD).

Enzymatic Prenylation of Proteins and Peptides: From Cysteine S‐Prenylation to Tryptophan‐Selective Biocatalysis

Chemistry – A European Journal, EarlyView.
This review highlights biocatalytic prenylation as a versatile strategy for tailoring the functional properties of peptides and proteins. By comparing branched isoprenoids with linear lipids, we illustrate how specific prenyl architectures modulate the behaviors of lipidated proteins within membrane environments.

Localization of the PE methylation pathway and SR-BI to the canalicular membrane

Journal of Lipid Research, 2003
To better understand the regulation of biliary phospholipid and cholesterol excretion, canalicular membranes were isolated from the livers of C57BL/6J mice and abundant proteins separated by SDS-PAGE and identified by matrix-assisted laser desorption ...

Pss knockdown in the midgut causes growth retardation in Drosophila similar to that in human LMHD

Developmental Dynamics, EarlyView.
Abstract Background Phosphatidylserine synthase (PSS), localized in the mitochondrial membrane, synthesizes phosphatidylserine. In humans, mutations in Pss lead to Lenz–Majewski hyperostotic dwarfism, a disorder affecting growth and development. The effects of Pss mutations on the growth of Drosophila melanogaster are not fully known. Hence, this study

Cross-Platform Comparison of Untargeted and Targeted Lipidomics Approaches on Aging Mouse Plasma. [PDF]

, 2018
Lipidomics - the global assessment of lipids - can be performed using a variety of mass spectrometry (MS)-based approaches. However, choosing the optimal approach in terms of lipid coverage, robustness and throughput can be a challenging task.

The Feasibility of Imaging Myocardial Ischemic/Reperfusion Injury Using \u3csup\u3e99m\u3c/sup\u3eTc-labeled Duramycin in a Porcine Model [PDF]

, 2015
When pathologically externalized, phosphatidylethanolamine (PE) is a potential surrogate marker for detecting tissue injuries. 99mTc-labeled duramycin is a peptide-based imaging agent that binds PE with high affinity and specificity.
