Brief Summary:The female ovary is essential for reproduction. Oocytes are stored in it for more than a year in mice, and for more than four decades in humans. This study investigated proteostasis in oocytes and ovaries of mice by combining quantitative mass spectrometry (MS), pulseĀchase labelling, single-cell RNA-seq and nanoscale secondary ion MS (NanoSIMS). They found extraordinary stability of hundreds of proteins. Long-lived proteins were enriched in diverse cellular...
