Active efflux systems in the solvent-tolerant bacterium Pseudomonas putida S12 [PDF]

, 2002
The aim of the research presented in this thesis was to study the molecular mechanisms of organic solvent tolerance in Pseudomonas putida S12. This bacterium is capable of growth at saturated solvent concentrations, which are lethal to normal bacteria ...

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Efflux pumps positively contribute to rifampin resistance in rpoB mutant Mycobacterium tuberculosis

Annals of Clinical Microbiology and Antimicrobials
Background While several recent studies have documented the importance of efflux pumps as mediators of rifampin (RIF) resistance, it remains uncertain which efflux pumps play major roles in rifampin-resistant Mycobacterium tuberculosis strains harboring ...

Expression of homologous RND efflux pump genes is dependent upon AcrB expression:implications for efflux and virulence inhibitor design [PDF]

, 2015
OBJECTIVES: Enterobacteriaceae have multiple efflux pumps that confer intrinsic resistance to antibiotics. AcrB mediates clinically relevant multidrug resistance and is required for virulence and biofilm formation, making it an attractive target for the ...

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

Advanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

6-gingerol enhances ciprofloxacin efficacy by inhibiting NorA efflux pump in Staphylococcus aureus

The Microbe
The drug efflux mechanism adopted by Staphylococcus aureus helps it in its survival under antibiotic pressure. The efflux pump NorA, a member of the MFS superfamily, effluxes out fluoroquinolones, biocides, quaternary ammonium compounds, and anti ...

Discovery of Novel Symmetrical 1,4-Dihydropyridines as Inhibitors of Multidrug-Resistant Protein (MRP4) Efflux Pump for Anticancer Therapy

Molecules, 2020
Despite the development of targeted therapies in cancer, the problem of multidrug resistance (MDR) is still unsolved. Most patients with metastatic cancer die from MDR.
