Unbiased proteomics and molecular analysis revealed a new role for S6K1 in regulating DNA repair through the orchestrated phosphorylation of CDK1 and MSH6. The findings may explain why RPS6KB1 gene amplification contributed to breast cancer drug resistance.

Class-A penicillin-binding proteins are dispensable for rod-like cell-shape but essential for mechanical integrity by sensing and repairing cell-wall defects locally, as investigated in the model system Escherichia coli.
An acetyl-CoA-mediated metabolic and epigenetic network has been elucidated that stimulates histone acetylation and anti-oxidative stress gene expression for heart repair after myocardial infarction.

Topoisomerase VI selectively catalyzes strand passage of DNA molecules juxtaposed at close to a right angle, which explains the observed chiral-dependent activity and preferential DNA decatenation versus supercoil relaxation.
Predictable patterns of fitness evolution observed in microbial evolution experiments can emerge generically as a consequence of widespread epistatic interactions between mutations.

The meiotic recombination landscape in vertebrates was re-engineered via the co-evolution of a dual histone H3K4/H3K36 methylation 'writer' PRDM9 and its 'reader' ZCWPW1 that facilitates efficient double strand break repair.
ZCWPW1 is a histone modification reader that localizes to DMC1-labelled double-strand break hotspots in a largely PRDM9-dependent manner, where it facilitates completion of synapsis by mediating DSB repair process.
