  This paper is a fundamental work in developmental biology that supports its findings with compelling evidence drawn from both theoretical and experiment insights. This work will be of interest to researchers in the fields of developmental and stem cell biology as it provides a potentially general mechanism for the control of a proliferative cell population.

  Evaluation Summary:

  The research presented in this manuscript is focused on testing the role of peroxiredoxin (Prdx5) and heterogeneous nuclear ribonucleoprotein K (hnRNPK) in bone biology and osteoporosis. Using cell-base and animal models, as well as various experimental methodologies the authors demonstrated that Prdx5 is upregulated during osteogenesis but suppressed during osteoclastogenesis. This novel function Prdx5 was found to be associated with binding and regulation of hnRNPK which controls the expression of genes involved in osteoclastogenesis, such as osteocalcin (Ocn).

  Evaluation Summary:

  The paper provides fundamental information through the identification of an E3 ligase and kinase/phosphatase regulatory machinery that regulates the inner nuclear membrane protein SUN2 using a GFP-based assay. The data reveal a model involving extraction of ubiquitylation of SUN2 from the membrane by p97, which is an important contribution to the field. Although the biochemical evidence is solid on the GFP-tagged SUN2 protein, one question is the extent to which this pathway works on endogenous SUN2 and the extent to which this is a quality control mechanism for turnover of unassembled SUN2 or whether it acts on the fully assembled complex.

  Evaluation Summary:

  Deposition of hyperphosphorylated misfolded tau is a hallmark of many neurodegenerative diseases, but the exact mechanisms by which misfolded tau spreads to adjacent areas of the brain are not known. In this manuscript, which will be of broad interest to cell biologists and neuroscientists, the authors suggest that tau fibrils that translocate directly through the cell membrane induce aggregation of cytosolic tau. While the results appear stunning, there are alternative explanations to the authors' hypothesis that require further investigation.
