JCSMR School Seminar Series - Mechanisms of regulating gene expression via selective mRNA transport

Dr Vihandha Wickramasinghe, Head - RNA Biology and Cancer Laboratory, Peter MacCallum Cancer Centre, Melbourne, VIC

Dr  Wickramasinghe's research interests lie in understanding the molecular basis of how messenger RNA (mRNA) is selectively processed and exported from the nucleus into the cytoplasm and how deregulation of these processes contributes to human cancer. He was awarded a Melbourne National Scholarship to undertake his undergraduate and honours degrees in Biomedical Science at the University of Melbourne. Following this, he was awarded a prestigious Medical Research Council pre-doctoral fellowship to undertake his PhD studies at the University of Cambridge in the United Kingdom.

During his subsequent post-doctoral studies at the MRC Cancer Unit in Cambridge, he demonstrated for the first time that selective mRNA export from the nucleus can regulate a fundamental biological process, namely DNA repair. The RNA Biology and Cancer Laboratory aims to characterise novel mechanisms of regulating gene expression via selective mRNA transport and to use these insights to identify potential new therapeutic targets for the treatment of cancer.
