Exploitation of DarT/DarG biology for a rational design of antimicrobial agents

Antibiotic resistant "superbugs" represent a major public health concern of the last 21th century, with an expected number of ten million deaths per year by 2050. Antimicrobial resistance occurs in a wide range of infectious diseases and it is promoted by the activation…

The DarT/DarG Toxin-Antitoxin ADP-Ribosylation System as a Novel Target for a Rational Design of Innovative Antimicrobial Strategies

Abstract The chemical modification of cellular macromolecules by the transfer of ADP-ribose unit(s), known as ADP-ribosylation, is an ancient homeostatic and stress response control system. Highly conserved across the evolution, ADP-ribosyltransferases and ADP-ribosylhydrolases control ADP-ribosylation signalling and cellular responses. In addition to proteins,…

microRNA-949 Favors H0-1 Expression in Neuroblastoma Cells Exposed to Oxidative Stress in a Bach1-Independent Way

Abstract Heme oxygenase 1 (HO-1) is crucially involved in cell adaptation to oxidative stress and has been demonstrated to play an important role in cancer progression and resistance to therapies. We recently highlighted that undifferentiated neuroblastoma (NB) cells are prone to counteract oxidative…
