Metallochaperones regulate intracellular copper levels. [PDF]

open access: yes, 2013
Copper (Cu) is an important enzyme co-factor that is also extremely toxic at high intracellular concentrations, making active efflux mechanisms essential for preventing Cu accumulation. Here, we have investigated the mechanistic role of metallochaperones

The MRP family of drug efflux pumps [PDF]

open access: yesOncogene, 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 ...

A mass spectrometry-based assay for improved quantitative measurements of efflux pump inhibition.

open access: yesPLoS ONE, 2015
Bacterial efflux pumps are active transport proteins responsible for resistance to selected biocides and antibiotics. It has been shown that production of efflux pumps is up-regulated in a number of highly pathogenic bacteria, including methicillin ...

Terpenes as bacterial efflux pump inhibitors: A systematic review

open access: yesFrontiers in Pharmacology, 2022
Managing antibiotic resistance is a significant challenge in modern pharmacotherapy. While molecular analyses have identified efflux pump expression as an essential mechanism underlying multidrug resistance, the targeted drug development has occurred ...

The porin and the permeating antibiotic: A selective diffusion barrier in gram-negative bacteria [PDF]

open access: yes, 2008
Gram-negative bacteria are responsible for a large proportion of antibiotic resistant bacterial diseases. These bacteria have a complex cell envelope that comprises an outer membrane and an inner membrane that delimit the periplasm.

Antisense PNA accumulates in Escherichia coli and mediates a long post-antibiotic effect [PDF]

open access: yes, 2007
Antisense agents that target growth-essential genes display surprisingly potent bactericidal properties. In particular, peptide nucleic acid (PNA) and phosphorodiamidate morpholino oligomers linked to cationic carrier peptides are effective in time kill ...

Indole contributes to tetracycline resistance via the outer membrane protein OmpN in Vibrio splendidus [PDF]

open access: yes, 2020
As an interspecies and interkingdom signaling molecule, indole has recently received attention for its diverse effects on the physiology of both bacteria and hosts. In this study, indole increased the tetracycline resistance of Vibrio splendidus.

Efflux pump proteins in antifungal resistance [PDF]

open access: yesFrontiers in Pharmacology, 2014
It is now well-known that the enhanced expression of ATP binding cassette (ABC) and major facilitator superfamily (MFS) proteins contribute to the development of tolerance to antifungals in yeasts. For example, the azole resistant clinical isolates of the opportunistic human fungal pathogen Candida albicans show an overexpression of Cdr1p and/or ...
