Rate My Professor Guillaume Chanfreau

Chanfreau's research employs genome-wide and systems biology approaches to investigate the integration of transcription and post-transcriptional processes that control eukaryotic gene expression, with a focus on Biology-related mechanisms of RNA metabolism. Using Saccharomyces cerevisiae as a primary model organism, his laboratory studies RNA degradation pathways mediated by ribonucleases such as the RNA exosome, quality control of aberrant transcripts, splicing efficiency and fidelity, transcription termination, coordination between 3'-end processing and splicing, and the role of RNA secondary structures in gene regulation. His work has elucidated novel pathways for RNA surveillance, stress-induced degradation, and cellular homeostasis, with implications for diseases involving RNA dysregulation. Key publications include "Sphingolipid signaling mediates iron toxicity" (Cell Metabolism, 2012), "Widespread impact of nonsense-mediated mRNA decay on the yeast intronome" (Molecular Cell, 2008), "Functions of the exosome in rRNA, snoRNA and snRNA synthesis" (EMBO Journal, 1999), "Transcription termination promotes splicing efficiency and fidelity in a compact genome" (PNAS, 2025), and "Trafficking of mitochondrial double-stranded RNA from mitochondria to the cytosol" (Life Science Alliance, 2024). With over 7,000 citations, his contributions have significantly influenced the understanding of RNA processing and its links to cellular physiology and pathology.
