  Evaluation Summary:

  This manuscript describes the regulation of ERK1/2, two protein kinases that play important roles in cell signaling, by protein cysteine palmitoylation. The intriguing observations reported here could be of broad interest to colleagues in the field of cell signaling and protein post-translational modifications. Mechanistic understanding is, however, still limited and the work would benefit from additional experimental evidence.

  Evaluation Summary:

  This report describes a new technique to detect the surface proteome of normal and myc-transformed cells in relation to extracellular vesicles from the same cells. The data obtained from this comparison may be useful in evaluating cell surface and extracellular vesicle marker proteins that may be of diagnostic value. The article could possibly be more interesting if the actual proteomic results of control vs Myc and cells vs extracellular vesicles were more extensively exploited.

  Evaluation Summary:

  This paper examines the effects of amylospheroids, highly neurotoxic assemblies of β-amyloid, on aortic function and on cultured cells. The authors propose that the interaction of amylospheroids with the sodium pump in endothelial cells induces production of reactive oxygen species to ultimately comprise nitric oxide generation. The study provides some new insight into mechanisms underlying brain blood vessel dysfunction and will be interesting neuroscientists who study neurovascular contribution to neurodegenerative diseases. The conclusions of the manuscript are supported by the data, but alternative approaches would make the study stronger.
