When the most potent combination of antibiotics selects for the greatest bacterial load: the smile-frown transition.

open access: yesPLoS Biology, 2013
Conventional wisdom holds that the best way to treat infection with antibiotics is to 'hit early and hit hard'. A favoured strategy is to deploy two antibiotics that produce a stronger effect in combination than if either drug were used alone.

Acute antagonism in three-drug combinations for vaginal HIV prevention in humanized mice

open access: yesScientific Reports, 2023
Adolescent girls and young women in low- to middle-income countries are disproportionately at risk of becoming HIV-1 infected. New non-vaccine biomedical products aimed at overcoming this global health challenge need to provide a range of safe, effective,

Prevalence and patterns of higher-order drug interactions in Escherichia coli. [PDF]

open access: yes, 2018
Interactions and emergent processes are essential for research on complex systems involving many components. Most studies focus solely on pairwise interactions and ignore higher-order interactions among three or more components.

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Molecular tuning of farnesoid X receptor partial agonism

open access: yesNature Communications, 2019
The ligand-activated transcription factor farnesoid X receptor (FXR) acts as a cellular sensor for bile acids and is of interest as a drug target. Here the authors employ X-ray crystallography and NMR to characterize the molecular determinants of FXR ...

Potency of vancomycin against Mycobacterium tuberculosis in the hollow fiber system model

open access: yesJournal of Global Antimicrobial Resistance, 2021
Objectives: To determine whether an inhaled vancomycin formulation resulting in high intrapulmonary 24-h area under the concentration–time curve (AUC0–24) could be optimised for tuberculosis treatment.

Modulation of neural cell membrane conductance by the herbal anxiolytic and antiepileptic drug aswal [PDF]

open access: yes, 2000
To evaluate the effects of aswal on ionic fluxes and neuronal excitation, we performed extracellular and whole cell patch clamp recordings on CA1 pyramidal neurons of guinea pigs and Long-Evans rats.

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization

open access: yesFEBS Letters, EarlyView.
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

In vivo screening for toxicity-modulating drug interactions identifies antagonism that protects against ototoxicity in zebrafish

open access: yesFrontiers in Pharmacology
Introduction: Ototoxicity is a debilitating side effect of over 150 medications with diverse mechanisms of action, many of which could be taken concurrently to treat multiple conditions.
