Abstract:
:Aberrant neutrophil (PMN) infiltration of the intestinal mucosa is a hallmark of inflammatory bowel diseases, including Crohn's disease and ulcerative colitis. While the genotoxic function of PMNs and its implications in carcinogenesis have been primarily associated with oxidative stress, recent work by Butin-Israeli and colleagues has defined a novel mechanism where PMN-derived microparticles through the delivery and activity of specific miRNAs promoted formation of double-strand breaks (DSBs), and in parallel, suppressed DSB repair through the downregulation of lamin B1 and Rad51. Respective downregulation of these two proteins compromised the nuclear envelope and high-fidelity repair by homologous recombination, increasing DSB accumulation and aneuploidy. This discovery defined a novel mode of action where PMN-mediated suppression of DSB repair leading to genomic instability in the injured mucosa may facilitate progression toward colorectal cancer.
