Cell paper combines computational and experimental biology to demonstrate new regulatory mechanism
Department of Biological Sciences faculty member Partho Sarothi Ray has recently co-authored a paper in the prestigious journal Cell [Yao P., Potdar A.A., Arif A., Ray P.S., Mukhopadhyay R., Willard B., Xu Y., Yan J., Saidel G.M. and Fox, P.L. (2012) Coding region polyadenylation generates a truncated tRNA synthetase that counters translation repression. Cell 149, 88-100] which describes a new mechanism of generating new proteins by converting a stop codon into an amino acid-encoding codon by adding an alternative poly-adenine tail to an mRNA. The significance of the study lies in the fact that the discovery is based on computational modeling of a translation regulatory system which was observed to give a constant low level of translation of a protein, vascular endothelial growth factor (VEGF), even when the synthesis of the protein was inhibited. This is one of the first studies which have utilized computational modeling together with experimental validation to discover a new molecular mechanism, emphasizing the interdisciplinary nature of scientific discovery today.
Rahul Basu receives Du Pré grant
Rahul Basu, a PhD student of Dr. Jayasri Das Sarma at the Department of Biological Sciences, IISER- Kolkata, is the recipient of the 2012 Du Pré grant. This prestigious research grant is awarded by the Multiple Sclerosis International Federation (MSIF) to young researchers from emerging countries to enable them to undertake short visits to established multiple sclerosis research centers, either to learn more from each other or to carry out parts of joint research projects. Rahul will use his £5000 grant to travel to the University of Pennsylvania, USA to spend 3 months working under the supervision of Dr Kenneth Shindler, looking at the role of conventional T cells and B cells in mouse hepatitis virus induced demyelination.
