Research Interests

Welcome to the Aye Lab! Our business is understanding reactive small-molecule-driven cellular communication processes. We are most well-known for our studies into electrophile signalling, but we also study nucleotide signalling pathways. Our work is slowly bringing both eclectic forms of cellular communication into focus. Critically, we have proven that electrophile signalling impinges on all aspects of cellular processes, and we have uncovered hidden aspects of nucleotide signalling pathways that serve to guard the genome. We pioneered the use of photocaged electrophiles (REX technologies) to bypass many of the limitations associated with the use of reactive electrophiles in cells and whole organisms. These technologies that can trigger protein specific electrophile-mediated signalling or can map the best electrophile sensors are proving to be uniquely useful. We have also used biochemistry, cell biology, genetics approaches to uncover novel roles of one of the most ancient enzymes, ribonucleotide reductase. Unsurprisingly, we are a multidisciplinary lab that uses organic chemistry, biochemistry, chemical, cell and molecular biology, genetics, and a number of model organisms to solve complex life processes. Our work is of significant relevance to human health. Through our united team effort, we strive to develop novel therapeutic and technological interventions, and to better understanding of current drugs through active collaborations with industrial scientists.

Biography

Yimon Aye is Professor of Chemistry & Chemical Biology at the University of Oxford, and tutorial fellow at Pembroke College. Aye was born and raised in Burma. She received a full scholarship to attend Cambridge Tutors College, UK (high school equivalent) and read chemistry at Somerville College, Oxford University, UK, as an international student scholar (2000-2004), during which time she worked with Prof. Stephen L. Buchwald (MIT, USA) and Prof. Stephen G. Davies (Oxford University, UK) as an undergraduate research assistant and Part-II thesis student, respectively. Aye subsequently moved to Harvard University (USA) and achieved her Ph.D. in organic chemistry under the supervision of Prof. David A. Evans (2004-2009). She then moved to MIT (USA) to research the cellular and biochemical regulatory mechanisms of the enzyme ribonucleotide reductase with Prof. JoAnne Stubbe. In her independent career that began in mid-2012, Aye set out to understand the detailed mechanisms of electrophile signaling. This impetus culminated in the development of “REX” technologies (T-REX™ delivery and G-REX™ profiling). In a parallel research program distinct from redox-dependent cell signaling, she studies proteins/pathways involved in mammalian genome maintenance and nucleotide signaling, including the mechanisms of anticancer agents in clinical use. Since January 2022, Aye has been serving as an associate editor of ACS Chemical Biology.
