Marc Fabian obtained his Ph.D. from York University, Toronto, Canada. He completed post-doctoral training with Dr. Nahum Sonenberg (McGill University) where he investigated how microRNAs post-transcriptionally regulate gene expression. Specifically, he focused on investigating how microRNAs inhibit the translation and subsequently promote the degradation of target mRNAs. In 2013, he joined the Lady Davis Institute as an independent investigator and obtained an Assistant Professor position in the Department of Oncology, McGill University.
Major Research Activities
Post-transcriptional control (PTC) programs regulate protein production after a messenger (m) RNA is transcribed from its DNA template. Many PTC programs control protein production by repressing mRNA translation and/or initiating mRNA destabilization, events collectively referred to as ‘silencing’. These programs are in general mediated by RNA binding proteins and ribonucleoprotein complexes that are recruited to specific mRNAs in order to engender silencing. Given their pervasive use, it is not surprising that many human cancers, as well as many other disorders, are associated with defects in gene silencing networks.
The overall theme of my research program is to investigate how microRNAs, RNA binding proteins and ribonucleoprotein complexes translationally repress and/or destabilize target mRNAs in mammalian cells. Ultimately, we wish to use this knowledge to develop new biotechnologies and to identify how aberrant post-transcriptional regulation of gene expression is linked to human disease.
