Extensive structure‐activity relationship study of albicidin’s C‐terminal dipeptidic p‐aminobenzoic acid moiety [PDF]

, 2019
Albicidin is a recently described natural product that strongly inhibits bacterial DNA gyrase. The pronounced activity, particularly against Gram‐negative bacteria, turns it into a promising lead structure for an antibacterial drug.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Aqueous Self-Assembly of Block Copolymers to Form Manganese Oxide-Based Polymeric Vesicles for Tumor Microenvironment-Activated Drug Delivery

Nano-Micro Letters, 2020
Highlights The formation of manganese oxide induces self-assembly of block copolymers to form polymeric vesicles. The polymeric vesicles possessed strong stability and high drug loading capacity. The drug-loaded polymeric vesicles have been demonstrated,

Poloxamers for Surface Modification of Hydrophobic Drug Carriers and Their Effects on Drug Delivery [PDF]

, 2014
Tri-block copolymer poloxamers are successfully employed for reducing adsorption of proteinous molecules onto hydrophobic surfaces, which will protect them from quick engulfing by macrophages.

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Designing the ideal perioperative pain management plan starts with multimodal analgesia. [PDF]

, 2018
Multimodal analgesia is defined as the use of more than one pharmacological class of analgesic medication targeting different receptors along the pain pathway with the goal of improving analgesia while reducing individual class-related side effects ...

Effective protocol for continuous pericapsular nerve group block in femur fracture patients undergoing hip surgery: two case reports [PDF]

Kosin Medical Journal
Pericapsular nerve group (PENG) block was introduced as an effective way to control postoperative pain in patients who have undergone hip surgery. Therefore, we would like to discuss how to perform PENG block accurately on the basis of two cases, both of
