• Maerker et al. Imeya 99J Dark Red Lace Front wigs For Women Long Burgundy Body 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.

    Many thanks to the organizers, speakers, presenters, and participants.


  • 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.

  • Krneta-Stankic et al. show that the Wnt/PCP formin Daam1 regulates cytoskeletal membrane dynamics and E-cadherin localization within developing nephrons.


    Published in Cell Reports.
