Cyclic AMP is a global virulence regulator governing inter and intrabacterial signalling in Acinetobacter baumannii.

Acinetobacter baumannii is an opportunistic nosocomial pathogen with high morbidity and mortality rates. Current treatment options for this pathogen are limited due to its increasing resistance to last-resort antibiotics. Despite A.

An improved genome editing system for Sphingomonadaceae.

The sphingomonads encompass a diverse group of bacteria within the family , with the presence of sphingolipids on their cell surface instead of lipopolysaccharide as their main common feature. They are particularly interesting for bioremediation purposes due to their ability to degrade or metabolise a variety of recalcitrant organic pollutants. However, research and development on their full bioremediation potential has been hampered because of the limited number of tools available to investigate and modify their genome.

Design, Synthesis, and Investigation of the Pharmacokinetics and Anticancer Activities of Indenoisoquinoline Derivatives That Stabilize the G-Quadruplex in the Promoter and Inhibit Topoisomerase I.

G-quadruplexes are noncanonical four-stranded DNA secondary structures. is a master oncogene and the G-quadruplex formed in the promoter functions as a transcriptional silencer and can be stabilized by small molecules. We have previously revealed a novel mechanism of action for indenoisoquinoline anticancer drugs, dual-downregulation of MYC and inhibition of topoisomerase I.

Disrupting iron homeostasis can potentiate colistin activity and overcome colistin resistance mechanisms in Gram-Negative Bacteria.

Acinetobacter baumannii is a Gram-negative priority pathogen that can readily overcome antibiotic treatment through a range of intrinsic and acquired resistance mechanisms. Treatment of carbapenem-resistant A. baumannii largely relies on the use of colistin in cases where other treatment options have been exhausted.
