282 Cytoplasmic polyadenylation activates quiescent transcripts for translation by selective poly(A)-tail extension. An approach involving a clickable adenosine derivative permits capture of newly polyadenylated transcripts, and next-generation sequencing reveals mRNA sequence motifs that are linked to polyadenylation.

281 The kinase Mst1, which acts in the Hippo pathway, controls cell proliferation, differentiation and apoptosis. Junichi Sadoshima and his colleagues show that Mst1 in cardiomyocytes phosphorylates the protein Beclin1 to coordinately suppress autophagy and promote apoptosis, thereby having deleterious effects on the heart.
