Replicative aging in yeast involves dynamic intron retention patterns associated with mRNA processing/export and protein ubiquitination

February 27, 2024

Saccharomyces cerevisiae has yielded relevant insights into some of the basic mechanisms of organismal aging. Among these are genomic instability, oxidative stress, caloric restriction and mitochondrial dysfunction. Our work uncovers a previously unexplored layer of the transcriptional program of yeast aging and, more generally, expands the knowledge on the occurrence of alternative splicing in baker´s yeast.

Time resolved DNA occupancy dynamics during the respiratory oscillation uncover a global reset point in the yeast growth program

September 1, 2014

Using multiple approaches, this work implies a nucleosome focusing event as a key step that resets transcription during the respiratory oscillation.
