Detection of tetracyclines and efflux pump inhibitors [PDF]
Antimicrobial Agents and Chemotherapy, 1993 Screening assays for the detection of tetracyclines and inhibitors of tetracycline efflux pumps are described. The tetracycline assay is based on the observation that the tetA(B) gene encoding the efflux pump of transposon Tn10 is induced by tetracycline.

Mechanisms of RND multidrug efflux pumps [PDF]
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2009 RND (Resistance-Nodulation-Division) family transporters are widespread especially among Gram-negative bacteria, and catalyze the active efflux of many antibiotics and chemotherapeutic agents. They have very large periplasmic domains, and form tripartite complexes with outer membrane channels and periplasmic adaptor proteins.

Insight into the AcrAB-TolC Complex Assembly Process Learned from Competition Studies
Antibiotics, 2021 The RND family efflux pump AcrAB-TolC in E. coli and its homologs in other Gram-negative bacteria are major players in conferring multidrug resistance to the cells.

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 ...

Efflux pump proteins in antifungal resistance [PDF]
Frontiers 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 ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

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
