How RNA decay promotes transcriptional rewiring during DNA replication stress
Raphael Loll-Krippleber from the Brown lab describes how yeast cells exposed to DNA replication stress induced by the anti-cancer drug hydroxyurea use RNA decay to reprogram gene expression. Using complementary functional genomics approaches Raphael found that a specific mRNA encoding the transcriptional repressor Yox1 is degraded at P-bodies sites to prevent accumulation of the Yox1 repressor in the nucleus. Up-regulation of YOX1 expression, as observed when P-body function is […]
