abstract：:In this issue of Molecular Cell, Basak et al. (2008) identify Prl-3 as a p53-inducible gene acting in DNA damage-induced cell-cycle arrest. Both deletion and overexpression of Prl-3 can be cytostatic, adding to a growing list of genes whose expression must be carefully titrated for proper cell proliferation. ...

abstract：:The Mre11-Rad50-Nbs1 (MRN) complex is a primary sensor of DNA double-strand breaks (DSBs). Upon recruitment to DSBs, it plays a critical role in catalyzing 5' --> 3' single-strand resection that is required for repair by homologous recombination (HR). Unknown mechanisms repress HR in G1 phase of the cell cycle during ...
