• Medial floor plate formation in zebrafish consists of two phases and requires trunk-derived Midkine-a
• Metal-responsive transcription factor(MTF-1) handles both extremes, copper load and copper starvation, by activating different genes
• Wnt signaling in the intestinal epithelium: from endoderm to cancer
• Kissing complex RNAs mediate interaction between the Fragile-X mental retardation protein KH2 domain and brain polyribosomes
• Delayed, asynchronous, and reversible T-lineage specification induced by Notch/Delta signaling
• TFIIIB subunit Bdp1p is required for periodic integration of the Ty1 retrotransposon and targeting of Isw2p to S. cerevisiae tDNAs
• Genome-wide identification of Isw2 chromatin-remodeling targets by localization of a catalytically inactive mutant
• WUSCHEL is a primary target for transcriptional regulation by SPLAYED in dynamic control of stem cell fate in Arabidopsis
• An MT1-MMP-PDGF receptor- axis regulates mural cell investment of the microvasculature
• The nucleolus as a stress sensor: JNK2 inactivates the transcription factor TIF-IA and down-regulates rRNA synthesis
• Replication checkpoint kinase Cds1 regulates Mus81 to preserve genome integrity during replication stress
