  • Noncanonical Modulation of the eIF2 Pathway Controls an Increase in Local Translation during Neural Wiring

    Cagnetta et al. published in Molecular Cell Sema3A triggers the phosphorylation of eIF2α in axons through an initial wave of local protein synthesis. eIF2α phosphorylation upregulates global translation, via differential eIF2B activity, and is required for neural wiring.

  • Rapid Cue-Specific Remodeling of the Nascent Axonal Proteome

    Cagnetta et al. published in Neuron a highly sensitive proteomics approach characterizing the nascent proteome of axons on a rapid timescale. Different extrinsic cues trigger distinct signatures of up-/down-regulated nascent protein changes within 5 minutes.

  • Evolutionarily conserved Tbx5-Wnt2/2b pathway orchestrates cardiopulmonary development

    Steimle et al. published in PNAS the evolutionary conservation of tbx5-wnt2/2b driving a bidirectional signaling loop between cardiopulmonary mesoderm and the foregut endoderm. This specifies endodermal pulmonary specification and mesodermal cardiac atrial septation.

  • Xenopus animal cap transcriptome

    Building a mucociliary epithelium.

    Angerilli et al.published in Nucleic Acids Research the dynamic transcriptional landscape in X. tropicalis Animal Cap explants during differentiation into mucociliary epithelium.

    Providing an online Web Tool, they detail global changes in mRNA expression, an unanticipated diversity of mRNA splicing isoforms, expression of repetitive DNA elements, and the complexity of circular RNAs.

  • Gene expression during Xenopus embryogenesis measured at single-cell resolution

    Briggs et al. performed single-cell RNA sequencing at 10 embryonic stages 5 to 22 hours post fertilization. Gene activity data read from the mRNA of 137,000 cells show that while the frog embryo appears to be in an undifferentiated state, cells begin to take on their eventual identities. Their findings are published in Science.
