During tumorigenesis loss of p53 not only abrogates cell cycle arrest and apoptosis, but also suppresses the induction of replication-stress-induced DNA double-stranded breaks.
Distinct interactions of AP endonuclease 1 with single-stranded DNA gaps and ATRIP and RPA protein complex address an outstanding question in the field of genome integrity regarding how ATR/ATRIP complex recruits onto damage site for ATR DNA damage response signaling.
After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.
Innate antiviral factors do not always perfectly distinguish between self and foreign, and potential adverse effects of antiviral defense mechanisms for the host have been discussed.

Conflicts between CRISPR-Cas systems and antibiotic resistance plasmids can be exploited to selectively eliminate antibiotic resistance from Enterococcus faecalis populations.
HOAP is a telomere-binding protein that has a conserved role in Drosophila, but it also needs to evolve quickly to restrict telomeric retrotransposons.
Multicellular and socially aggregating prokaryotes contain previously undescribed, chaperone-based systems predicted to mediate defensive biological conflicts, several components of which are thematically similar antecedents of eukaryotic apoptosis pathways.
The pervasive transcription environment alters the efficiency of firing of replication origins, which are 'protected' by roadblock termination due to origin recognition complex (ORC) and pre-RC complexes.
