The ability of antibodies to extravasate out of blood vessels is critical for therapeutic activity, because molecular targets for most diseases are located outside of the endothelial lining. By performing detailed biodistribution studies with a novel IL9-armed cancer-specific antibody, we

Transcription errors occur in all living cells; however, it is unknown how these errors affect cellular health. To answer this question, we monitor yeast cells that are genetically engineered to display error-prone transcription. We discover that these cells suffer from

In mammalian spermiogenesis, haploid round spermatids undergo dramatic biochemical and morphological changes and transform into motile mature spermatozoa. A majority of the histones are replaced by transition proteins during mid-spermiogenesis and later replaced by protamines, which occupy the sperm chromatin.

Traditionally viewed as an autodigestive pathway, autophagy also facilitates cellular secretion; however, the mechanisms underlying these processes remain unclear. Here, we demonstrate that components of the autophagy machinery specify secretion within extracellular vesicles (EVs). Using a proximity-dependent biotinylation proteomics strategy
