Description
The striking PNS regenerative response to injury rests on the plasticity of adult Schwann cells and their ability to transit between differentiation states, a highly unusual feature in mammals. Using mice with inactivation of Schwann cell c-Jun, we show that the injury response involves c-Jun dependent natural reprograming of differentiated cells to generate a distinct Schwann cell state specialized to promote regeneration. Transected distal stumps of c-Jun mutants show 172 disregulated genes, resulting in abnormal expression of growth factors, adhesion molecules and cytoskeletal changes that lead to neuronal death, inhibition of axon growth and striking failures of functional repair after injury. These observations provide a molecular basis for understanding Schwann cell plasticity and nerve regeneration. They offer conclusive support for the notion that Schwann cells control repair in the PNS, using dedicated transcriptional controls to generate a distinct repair cell, a transition that shows similarities to transdifferentiation seen in other systems.

Description
During oogenesis, DNA methyltransferase 3-like (Dnmt3l) is required for the establishment of the maternal germline DNA methylation imprints that in the offspring, govern the parent-of-origin-specific expression of most known imprinted genes (Science 2001, 294:2536-9). Dnmt3l-deficient dams were crossed with wildtype sires to obtain Dnmt3l-/+ embryos that lack maternal methylation imprints. Gene expression was measured in Dnmt3l-/+ and wildtype embryos and is expected to differ for imprinted genes that are under the control of a maternal methylation mark.

Description
Based on the differential comparison of transcriptomes of Homo-, hetero-zygote (Het) and wild type (Wt), in vivo protein-trap mutagenesis system, we have produced series of expression codex of the zebrafish. Here , we reported the transcriptomic characteristic of a line with stable deficits found in homozygote (Homo) expressing the strongest signal of red fluorescent protein (mRFP) in the central neural system and vascular system.

Description
The genetic mechanism governing the spatial patterning of teeth still remains to be elucidated. Sonic hedgehog (Shh) is one of key signaling molecules involved in the spatial patterning of teeth. By utilizing maternal transfer of 5E1 (an IgG1 monoclonal antibody against Shh protein) through the placenta to block Shh signaling, we investigated the changes in tooth patterning and in gene expression.
