Transcriptional and post-transcriptional regulation of autophagy in the yeast Saccharomyces cerevisiae .

Autophagy is a highly conserved catabolic pathway that is vital for development, cell survival, and the degradation of dysfunctional organelles and potentially toxic aggregates. Dysregulation of autophagy is associated with cancer, neurodegeneration, and lysosomal storage diseases. Accordingly, autophagy is precisely regulated at multiple levels (transcriptional, post-transcriptional, translational, and post-translational) to prevent aberrant activity. Various model organisms are used to study autophagy, but the baker's yeast Saccharomyces cerevisiae continues to be advantageous for genetic and biochemical analysis of non-selective and selective autophagy. In this Minireview, we focus on the cellular mechanisms that regulate autophagy transcriptionally and post-transcriptionally in S. cerevisiae .
