Bacterial intoxication evokes cellular senescence with persistent DNA damage and cytokine signalling
Original language description
Cytolethal distending toxins (CDT) are proteins produced and secreted by facultative pathogenic strains of gram-negative bacteria with potentially genotoxic effects. We found both normal and cancer human cells exposed to CDT, surviving the acute phase ofintoxication by Haemophilus ducreyi CDT, possess the main hallmarks of cellular senescence including persistently activated DNA damage signalling, expansion of promyelocytic leukaemia nuclear compartment and induced expression of several cytokines (e.g.IL-6, IL-8 and IL-24). We conclude that analogous to oncogenic, oxidative and replicative stresses, bacterial toxins represent another pathophysiological stimulus that induces premature senescence. Thus, the activation of cellular senescence as the anticancer barrier, together with evidence of chromosomal defects reported here, support the emerging genotoxic and potentially oncogenic effects of this group of bacterial toxins, and warrant further research of their role in human disease.
