  • RSPO2 inhibition of RNF43 and ZNRF3 governs limb development independently of LGR4/5/6
    - 2018-06-14

    Four R-spondin secreted ligands (RSPO1-RSPO4) act through their LGR4, LGR5 and LGR6 receptors amplifying WNT signalling. An allelic series of recessive RSPO2 mutations in humans causes tetra-amelia syndrome, characterized by lung aplasia and a total absence of the four limbs. Szenker-Ravi et al. published in Nature that RSPO2, without the LGR4/5/6 receptors, serves as a direct antagonistic ligand to RNF43 and ZNRF3, constituting a master switch that governs limb specification.

  • miR-182 Regulates Slit2-Mediated Axon Guidance by Modulating the Local Translation of a Specific mRNA
    - 2017-04-05

    Bellon et al. published in Cell Reports the role of microRNAs in mRNA-specific translation during axonal pathfinding of Xenopus laevis retinal ganglion cells (RGCs). They found that miR-182 targets cofilin-1 mRNA, silencing its translation. Slit2 rapidly relieves this repression without causing miR-182 degradation. Their data support a model where miR-182 reversibly gates the selection of certain mRNAs for fast translation depending on extrinsic cues.

  • Mechanosensing is critical for axon growth in the developing brain
    - 2016-11-16

    Koser et al. identify mechanical signals as important regulators of axon pathfinding. In vitro, substrate stiffness determined growth patterns of Xenopus retinal ganglion cell axons. In vivo atomic force microscopy revealed a noticeable pattern of stiffness gradients in the embryonic brain.

  • A simple and efficient method to visualize and quantify the efficiency of chromosomal mutations from genome editing
    - 2016-11-14

    Fu et al. published in Science Reports a simple and efficient method to visualize and quantify the efficiency of genomic mutations induced by genome-editing. Their approach is based on the expression of a two-color fusion protein in a vector that allows the insertion of the edited region in the genome in between the two color moieties.

  • Direct reprogramming of fibroblasts into renal tubular epithelial cells by defined transcription factors
    - 2016-11-14

    Kaminski et al. identified 4 factors that are able to directly reprogram fibroblasts into renal tubule cells.

    Induced renal tubule epithelial cells (iRECs) are similar to their native counterparts with respect to their transcriptional profile and morphological features, and can integrate into kidney organoids and decellularized kidneys.

    Their research is published in Nature Cell Biology.
