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

, 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-mediated resistance in chemotherapy

Annals of Medical and Health Sciences Research, 2012
Efflux pump mechanisms perform important physiological functions such as prevention of toxin absorption from the gastrointestinal tract, elimination of bile from the hepatocytes, effective functioning of the blood-brain barrier and placental barrier, and renal excretion of drugs.

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections 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

Beyond Antimicrobial Resistance: Evidence for a Distinct Role of the AcrD Efflux Pump in Salmonella Biology

mBio, 2016
For over 20 years, bacterial multidrug resistance (MDR) efflux pumps have been studied because of their impact on resistance to antimicrobials. However, critical questions remain, including why produce efflux pumps under non-antimicrobial treatment ...

Triclocarban Influences Antibiotic Resistance and Alters Anaerobic Digester Microbial Community Structure [PDF]

, 2016
Triclocarban (TCC) is one of the most abundant organic micropollutants detected in biosolids. Lab-scale anaerobic digesters were amended with TCC at concentrations ranging from the background concentration of seed biosolids (30 mg/kg) to toxic ...

Predictors of response and rational combinations for the novel MCL‐1 inhibitor MIK665 in acute myeloid leukemia

Molecular Oncology, EarlyView.
This study characterizes the responses of primary acute myeloid leukemia (AML) patient samples to the MCL‐1 inhibitor MIK665. The results revealed that monocytic differentiation is associated with MIK665 sensitivity. Conversely, elevated ABCB1 expression is a potential biomarker of resistance to the treatment, which can be overcome by the combination ...

Contribution of efflux to the emergence of isoniazid and multidrug resistance in Mycobacterium tuberculosis. [PDF]

PLoS ONE, 2012
Multidrug resistant (MDR) tuberculosis is caused by Mycobacterium tuberculosis resistant to isoniazid and rifampicin, the two most effective drugs used in tuberculosis therapy.

Draft Genome Sequence of the Biofilm-Forming Stenotrophomonas maltophilia Strain 53 [PDF]

, 2015
A clinical strain of Stenotrophomonas maltophilia (designated strain 53) was obtained, and a whole-genome sequence was generated. The subsequent draft whole-genome sequence demonstrated the presence of a number of genes encoding for proteins involved in ...
