Efflux pumps and microbial biofilm formation

Infection, Genetics and Evolution, 2023
Biofilm-related infections are resistant forms of pathogens that are regarded as a medical problem, particularly due to the spread of multiple drug resistance. One of the factors associated with biofilm drug resistance is the presence of various types of efflux pumps in bacteria.

Vibrio cholerae VexH encodes a multiple drug efflux pump that contributes to the production of cholera toxin and the toxin co-regulated pilus. [PDF]

PLoS ONE, 2012
The resistance-nodulation-division (RND) efflux systems are ubiquitous transporters that function in antimicrobial resistance. Recent studies showed that RND systems were required for virulence factor production in Vibrio cholerae. The V. cholerae genome

Efflux Pumps and These Inhibitors

VNU Journal of Science: Medical and Pharmaceutical Sciences, 2019
 In this era of multi-drug resistance, efflux pump is one of the major problems which is increasingly concerned by scientists. The structure and mechanism activity of the efflux pumps on both bacteria and eurakyotes that are gradually being clarified. Since then, efflux pump inhibitors have also been studied and initially applied in clinic, that makes ...

The MRP family of drug efflux pumps [PDF]

Oncogene, 2003
The MRP family is comprised of nine related ABC transporters that are able to transport structurally diverse lipophilic anions and function as drug efflux pumps. Investigations of this family have provided insights not only into cellular resistance mechanisms associated with natural product chemotherapeutic agents, antifolates and nucleotide analogs ...

Introduction: Transporters, Porins, and Efflux Pumps [PDF]

Chemical Reviews, 2021
All living cells are surrounded by lipidic membranes that separate metabolic and macromolecular biosynthetic processes from external environments. Biological membranes vary dramatically in their composition and structures and are optimized by mega-annum of evolution to effectively carry out diverse biological functions including energy production ...

Fluorescence-Based Flow Sorting in Parallel with Transposon Insertion Site Sequencing Identifies Multidrug Efflux Systems in Acinetobacter baumannii

mBio, 2016
Multidrug efflux pumps provide clinically significant levels of drug resistance in a number of Gram-negative hospital-acquired pathogens. These pathogens frequently carry dozens of genes encoding putative multidrug efflux pumps.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Fighting back against bacterial resistance: Harnessing nanocarrier strategies to counter antibiotic efflux pumps

Next Materials
The global rise of multidrug-resistant (MDR) bacterial infections poses a significant threat to public health, mainly driven by antibiotic efflux pumps that actively expel drugs from bacterial cells and lower intracellular antibiotic concentrations below

Efflux Pump-mediated Drug Resistance in Burkholderia

Frontiers in Microbiology, 2015
Several members of the genus Burkholderia are prominent pathogens. Infections caused by these bacteria are difficult to treat because of significant antibiotic resistance.
