RND-type Drug Efflux Pumps from Gram-negative bacteria: Molecular Mechanism and Inhibition

Frontiers in Microbiology, 2015
Drug efflux protein complexes confer multidrug resistance on bacteria by transporting a wide spectrum of structurally diverse antibiotics. Moreover, organisms can only acquire resistance in the presence of an active efflux pump.

The potential impact of H1 antihistamines on clinical outcomes in NSCLC patients undergoing EGFR‐TKIs treatment

British Journal of Clinical Pharmacology, EarlyView.
Background Epidermal growth factor receptor–tyrosine kinase inhibitors (EGFR‐TKIs) have substantially improved outcomes in non‐small cell lung cancer (NSCLC); however, the development of treatment resistance remains a major clinical challenge. This study examines the association between concomitant prescriptions of H1‐antihistamines (H1AHs) and ...

Subfunctionalization influences the expansion of bacterial multidrug antibiotic resistance

BMC Genomics, 2017
Background Antibiotic resistance is a major problem for human health. Multidrug resistance efflux pumps, especially those of the Resistance-Nodulation-Cell Division (RND) family, are major contributors to high-level antibiotic resistance in Gram-negative

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Efflux Pump Gene Expression in Erwinia chrysanthemi Is Induced by Exposure to Phenolic Acids

Molecular Plant-Microbe Interactions, 2007
Salicylic acid (SA) is an important signaling molecule in local and systemic plant resistance. Following infection by microbial pathogens and the initial oxidative burst in plants, SA accumulation functions in the amplification of defense gene expression.

How to Measure Export via Bacterial Multidrug Resistance Efflux Pumps [PDF]

, 2016
Bacterial multidrug resistance (MDR) efflux pumps are an important mechanism of antibiotic resistance and are required for many pathogens to cause infection. They are also being harnessed to improve microbial biotechnological processes, including biofuel

Labeling Strategies for Monitoring Cytoskeleton Dynamics in Cultured Epithelial Cells

Cytoskeleton, EarlyView.
ABSTRACT Collective cell migration relies on coordinated cytoskeletal remodeling, yet the impact of live‐cell actin filament probes on these dynamics remains poorly characterized. Here, we systematically compared the performance and cellular effects of fluorogenic jasplakinolide‐based probes, SiR‐actin and SiR‐XActin, with the genetically encoded ...

Quantitative Systems Toxicology Model Predicts Obeticholic Acid‐Associated Liver Injury in Metabolic Dysfunction‐Associated Steatotic Liver Disease

Clinical Pharmacology &Therapeutics, EarlyView.
Obeticholic acid (OCA), a synthetic analog of chenodeoxycholic acid, was approved in 2016 for the treatment of primary biliary cholangitis. Early clinical trials revealed elevated liver biomarkers in healthy subjects receiving supratherapeutic OCA doses (100–250 mg).

An allosteric transport mechanism for the AcrAB-TolC multidrug efflux pump

eLife, 2017
Bacterial efflux pumps confer multidrug resistance by transporting diverse antibiotics from the cell. In Gram-negative bacteria, some of these pumps form multi-protein assemblies that span the cell envelope.

Integrated assessment of rifampicin‐mediated induction of transporters and drug‐metabolizing enzymes in a long‐term human liver tissue chip system

Clinical Pharmacology &Therapeutics, EarlyView.
Rifampicin is a prototypical clinical inducer used in drug–drug interaction (DDI) studies. However, the clinical relevance and predictability of rifampicin‐mediated hepatic transporter induction remain poorly defined. Conventional hepatocyte culture models fail to capture clinically relevant regulation of transporters and drug‐metabolizing enzymes ...
