The Pkpk and Pksple isoforms of the Prickle protein determine right- or left-handed bristle morphogenesis by coupling Frizzled/Vang signaling to the Fat/Dachsous PCP directional signal in opposite directions.
Building on previous work (Doroquez et al., 2014), it is shown that the centriole core of the basal body degenerates, but the outer wall remodels to template the ciliary axoneme in a subset of C. elegans ciliated sensory neurons.
miR-31 drives proliferation of intestinal stem cells, and protects intestinal stem cells against apoptosis both during homeostasis and regeneration in response to ionizing radiation injury, and promotes intestinal tumorigenesis through regulation of multiple signaling pathways.
FGF signalling is responsible for priming the developmental enhancer ZRS across the distal limb mesenchyme during development, allowing ETS factors to modulate its activity through balancing histone acetylation.
The gene regulatory network controlling directed cell migration in a sea urchin is strikingly similar to a sub-circuit for eye development in Drosophila, suggesting that ancient systems-level controls may be adapted for diverse functions in different animals.
