• Pokrovsky et al. publish in PLoS Biology their study investigating the relationship between the propagation of epigenetic information (histone modification profiles) and the developmental cell proliferation during Xenopus embryogenesis.

  • Getwan et al. publish in PNAS their work studying skeletal ciliopathies. A data mining-based in silico screen found ttc30a to be related to known skeletal ciliopathy genes. CRISPR/Cas9 targeting replicated limb malformations and renal cysts identical to the models of established disease genes.

  • Maerker et al. published in Nature Communications show that pkd2-mediated post-transcriptional repression dand5 through bicc1 and dicer is a central process in symmetry breaking. Ciliary activity of the calcium channel Pkd2 is crucial for asymmetric leftward flow sensing at the vertebrate left-right organizer.

  • Animal interphase chromosomes are organized into topologically associating domains (TADs). Niu et al. show that X. tropicalis is a powerful model for chromosome architecture analysis suggesting that chromatin remodeling plays an essential role in de novo TAD establishment. Published in Nature Genetics.

  • An upcoming book to be released by CRC Press.
