A comprehensive review of cancer‐induced cardiac wasting

British Journal of Pharmacology, EarlyView.
Cancer is frequently accompanied by cachexia, a systemic syndrome characterized by progressive loss of skeletal muscle mass, with or without loss of fat mass. Increasing evidence indicates that cancer can also induce cardiac muscle wasting, which is associated with structural cardiac remodelling, impaired contractile function and the development of ...

Opposing roles of DGAT‐mediated lipid droplet biogenesis in the regulation of ferroptosis sensitivity

The FEBS Journal, EarlyView.
Ferroptosis is driven by unrestricted peroxidation of polyunsaturated fatty acyl (PUFA) chains in membrane phospholipids. In triple‐negative breast cancer cells, lipid droplets (LDs) sequester dietary PUFAs, limiting their incorporation into membrane phospholipids, preventing mitochondrial damage, and reducing lipid peroxidation and ferroptosis.

Formation of electrophilic oxidation products from mitochondrial cardiolipin in vitro and in vivo in the context of apoptosis and atherosclerosis

Redox Biology, 2014
Emerging evidence indicates that mitochondrial cardiolipins (CL) are prone to free radical oxidation and this process appears to be intimately associated with multiple biological functions of mitochondria.

Cryo‐EM structures of multiple‐peptide resistance factor (MprF) from Pseudomonas aeruginosa

The FEBS Journal, EarlyView.
Cryo‐EM analysis of MprF from Pseudomonas aeruginosa reveals a dimeric enzyme, distinct from Rhizobium homologues. The soluble GNAT domain contains a dynamic amphipathic helix (TTH) that adopts different positions in detergent micelle and nanodisc, relative to the membrane.

Aptamer‐mediated outer membrane destabilization overcomes low permeability resistance in Pseudomonas aeruginosa

The FEBS Journal, EarlyView.
DNA aptamers, Apt 60 and Apt 173, target the BamA protein to compromise outer membrane integrity in Pseudomonas aeruginosa, making it susceptible to Azithromycin, an antibiotic that is otherwise poorly effective due to the low‐permeability membrane.

Dysfunctional copper homeostasis in Caenorhabditis elegans affects genomic and neuronal stability

Redox Biochemistry and Chemistry
While copper (Cu) is an essential trace element for biological systems due to its redox properties, excess levels may lead to adverse effects partly due to overproduction of reactive species. Thus, a tightly regulated Cu homeostasis is crucial for health.

Subcellular organelle lipidomics in TLR-4-activated macrophages1[S]

Journal of Lipid Research, 2010
Lipids orchestrate biological processes by acting remotely as signaling molecules or locally as membrane components that modulate protein function. Detailed insight into lipid function requires knowledge of the subcellular localization of individual ...

Toward understanding the catalytic mechanism for two classes of bacterial phospholipid N‐methyltransferases

The FEBS Journal, EarlyView.
Phospholipid N‐methyltransferases (Pmts) synthesize phosphatidylcholine in many bacteria. In this study, we compared the catalytic mechanisms of two bacterial Pmt classes: the Rhodobacter (R‐) and the Sinorhizobium (S‐) type. Representative enzymes for each class were derived from Rubellimicrobium thermophilum and Agrobacterium tumefaciens ...

Focal Targeting of the Bacterial Envelope by Antimicrobial Peptides

Frontiers in Cell and Developmental Biology, 2016
Antimicrobial peptides (AMPs) are utilized by both eukaryotic and prokaryotic organisms. AMPs such as the human beta defensins, human neutrophil peptides, human cathelicidin, and many bacterial bacteriocins are cationic and capable of binding to anionic ...

Design and Implementation of an Automated Interpretation Algorithm for Lupus Anticoagulant Functional Testing

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction Lupus anticoagulant (LA) testing is essential, albeit complex, in the laboratory diagnosis of antiphospholipid syndrome (APS). Given the multi‐step workflow and the variability introduced by anticoagulant therapy, reagent differences, and interpretive approaches, result interpretation requires expert evaluation.
