  eLife Assessment

  In their valuable study, Lee et al. explore a role for the Hippo signaling pathway, specifically wts-1/LATS and the downstream regulator yap, in age-dependent neurodegeneration and microtubule dynamics using C. elegans mechanosensory neurons as a model. The authors demonstrate that disruption of wts-1/LATS leads to age-associated morphological and functional neuronal abnormalities, linked to enhanced microtubule stabilization, and show a genetic connection between yap and microtubule stability. Overall, the study employs robust genetic and molecular approaches to reveal a convincing link between the Hippo pathway, microtubule dynamics, and neurodegeneration.

  This important study investigates the different mechanisms that provide instructions for a missing body part to regenerate its appropriate identity. The authors use two species of planarians to identify a key role for bodywide canonical Wnt gradients in controlling the outcome of regeneration. The study provides convincing evidence for variable regeneration efficiency among planarian species that will be of interest to developmental biologists interested in regeneration. However, some of the results are over-interpreted and the additional experiments could provide better support for the authors' claims.

  Lu and colleagues developed an important imaging protocol that combines expansion microscopy, light-sheet microscopy, and image segmentation for use with the planarian Schmidtea mediterranea, a powerful model system for regeneration. This represents a substantial improvement on current standards and enables more rapid data acquisition. The utility of this solid protocol is demonstrated by quantifying several aspects of this flatworm's neural anatomy and musculature during homeostasis and regeneration. This work will be of interest to researchers looking to implement more systematic approaches towards imaging and quantifying intact specimens.

  eLife Assessment

  This valuable manuscript uses mathematical modeling to address the synchrony of the vertebrate segmentation clock with the developmental processes. The authors use convincing arguments to support the idea that this would allow the evolution of flexible body plans and a variable number of segments. This manuscript could be of interest to developmental biologists and systems biologists.

Extracellular adenosine deamination primes tip organizer development in Dictyostelium

1. Pavani Hathi

• Curated by eLife

  eLife Assessment

  This valuable study identifies a protein called adenosine deaminase-related growth factor (ADGF) as a key regulator of tip formation in the slime mold Dictyostelium discoideum. The authors convincingly show that ADGF catalyses the formation of ammonia from adenosine, allowing ammonia to initiate tip formation, and then elucidate pathways upstream and downstream from ADGF. The authors discuss the intriguing possibility that mammalian ADGF may also similarly regulate development.
