  Evaluation Summary:

  Lucas, Himes et al. present multiple practical improvements to the 2D high-resolution template-matching (2DTM) routine for cryo-EM images originally described by Rickgauer et al., eLife 2017. GPU-acceleration and integration into cisTEM make the approach substantially faster and easier to use than the previous CPU-based Matlab implementation. The strengths and weaknesses of the 2DTM are clearly presented and the comparison with 3DTM is thorough. At present the 2DTM approach is likely only suitable for analysis of large assemblies (e.g., ribosomes, proteasomes,etc.) in situ, but future improvements in microscope hardware and the 2DTM routine itself will likely allow application of this approach to smaller complexes.

  Evaluation Summary:

  This paper is of interest for cell biologists studying mitochondrial fission as well as stem cell biologists studying neoplastic transformation. The work helps to clarify how variable levels of the master regulator of mitochondrial fission can have substantially different effects on gene regulation and mitochondrial network properties. A combination of complementary methods is used to support the key findings although aspects of data analysis and quantification could be improved.

• Curated by eLife

  Evaluation Summary:

  This manuscript reports a robust and well-characterized expansion method that achieves 10X expansion with a single expansion step using a simple, easy-to-use protocol. The new protocol leads to an enabling methodology for super-resolution imaging of various sub-cellular structures and organelles and is likely to have a high impact.

Long-range migration of centrioles to the apical surface of the olfactory epithelium

• Curated by eLife

  Evaluation Summary:

  Analyzing the long-distance migration of centrioles to the dendrite tip of multicilated olfactory neurons in mice, Ching et al. use expansion microscopy to show that centrioles migrate as clusters, which mature as they reach the apical surface. The super-resolution data are impressive and the claims are generally supported by the data. Although the manuscript is largely descriptive, it is an important addition to the field, and will be of broad interest to cell biologists.

  Evaluation Summary:

  The authors investigate the role of the PI3P 5-kinase protein (PIKfyve) in endosome to cell surface recycling. They report that PIKfyve function is necessary for cell migration and endsomal recycling of integrin proteins via the SNX17-Retriever pathway. The findings will be of interest to the endosomal research community.
