Frédérick Antoine Mallette, PhD, heads the Chromatin Structure and Cellular Senescence Research Unit. He is also an associate professor in the Department of Biochemistry and Molecular Medicine at Université de Montréal and the Canada Research Chair in Epigenetics of Aging and Cancer (Tier 2).
The research of Frédérick Antoine Mallette and his team aim to elucidate the molecular mechanisms of cancer formation to identify new pathways that limit tumour progression. The team is interested in senescence (a form of premature cell aging), which provides significant anti-tumour protection. The team also studies genetic defects that inactivate the cell's natural cancer defence mechanisms. In 2016, Frédérick Antoine Mallette and his colleague Marc-Étienne Huot from Université Laval published a study in the prestigious scientific journal Nature Communications. The findings from this study have led to a better understanding of the molecular causes of brain cancer and leukemia and opened the door to more effective personalized chemotherapy.

Chromatin Structure and Cellular Senescence
Research interests
- Investigate the role of lysine methylation in senescence and cancer by studying the JUMONJI family of lysine demethylases.
- The regulatory mechanisms of lysine demethylases as well as the biological role of demethylation during different cellular processes including proliferation, transcriptional regulation, the DNA damage response, and tumorigenesis.
- Identify new therapeutic targets to treat cancer. To achieve this goal, the laboratory integrates different systems and approaches [in genomics (ChIP-chip, ChIP-seq, RNA-seq and microarray chips), proteomics (MS/MS), cytology (fluorescent microscopy, immunohistochemical markers), and genetics (cell and mouse lines)] to elucidate the role of demethylases in different biological pathways.
- Analyze the effects of the deregulated expression of demethylases on heterochromatin formation during oncogene-induced senescence (a tumour suppression mechanism).
- Determine the signalling pathways regulated by demethylases and their role in cell transformation.
