    Primary cilia deficiency in neural crest cells models anterior segment dysgenesis in mouse

    Céline Portal et al.
    Primary cilia of neural crest-derived cells mediate Indian hedgehog-induced signal transduction in the periocular mesenchyme and are required for normal anterior segment development.

    TERRA regulate the transcriptional landscape of pluripotent cells through TRF1-dependent recruitment of PRC2

    Rosa María Marión et al.
    Telomeric TRF1 controls the transcriptional programmes of pluripotent stem cells by recruiting PRC2 to pluripotency and differentiation genes by controlling the expression of those gene sites and the binding of TERRA RNAs to them.

    Nuclear receptor NR4A is required for patterning at the ends of the planarian anterior-posterior axis

    Dayan J Li et al.
    NR4A is a broadly conserved transcription factor that is required for concordance of patterning information and anatomy at both ends of the planarian anterior-posterior axis.
