The ALPK1/TIFA/NF-κB axis links a bacterial carcinogen to R-loop-induced replication stress

The bacterial pathogen Helicobacter pylori is known for its ability to induce DNA double-strand breaks in the genome of its target cells. Here, we show that H. pylori-induced DNA damage and replication stress occurs in S-phase cells as a result of R-loop-mediated transcription/replication conflicts...

Description
Summary:The bacterial pathogen Helicobacter pylori is known for its ability to induce DNA double-strand breaks in the genome of its target cells. Here, we show that H. pylori-induced DNA damage and replication stress occurs in S-phase cells as a result of R-loop-mediated transcription/replication conflicts that are triggered by activation of the ALPK1/TIFA/NF-κB signaling axis.
