Gracjan Michlewski is a Senior Lecturer (Zhejiang) in Biomedical Sciences at The University of Edinburgh. He obtained his PhD and Habilitation from the Institute of Bioorganic Chemistry, Polish Academy of Sciences in Poznan, Poland. Gracjan has been a postdoctoral fellow in the Human Genetics Unit, Medical Research Council in Edinburgh. In 2011, he established his laboratory at The Wellcome Trust Centre for Cell Biology, University of Edinburgh with Medical Research Council Career Development Award.
Gracjan’s main research interests are associated with regulation of gene expression, RNA processing and innate immune response to RNA viruses. He discovered a number of factors and mechanisms that regulate production of miRNAs (short non-coding RNAs that control physiological and pathological gene expression pathways). He demonstrated that E3 ubiquitin ligase TRIM25 (a key player in innate immune response to RNA viruses) is a novel RNA-binding protein. Finally, Gracjan showed that Oleic Acid (a natural ω-9 monounsaturated fatty acid produced by various plants and animal cells) directly stimulates the production of tumour suppressor miRNA. His findings have far reaching consequences for our understanding of how RNA-binding proteins and metabolites regulate gene expression, RNA processing and innate immunity.
Gracjan is involved in developing and delivering undergraduate and postgraduate teaching at the Zhejiang University-University of Edinburgh Institute.
