More than a decade of research shows that the nucleolus—the largest structure in the eukaryotic nucleus—plays a pivotal role in aging. Now, a new study analyzing yeast cells suggests both that ...

As an outgrowth of former studies of transport along the secretory path, mitochondrial inheritance, the causes of aneuploidy and export from the nucleus, we are presently investigating the functional ...
