Soumitra Basu
Biography
Dr. Basu received his PhD from Sidney Kimmel Cancer Center in Philadelphia in Prof Eric Wickstrom鈥檚 lab. He did his post-doctoral research in Prof Scott Strobel鈥檚 lab at Yale University鈥檚 Molecular Biophysics and Biochemistry department. Following which Dr. Basu joined as an assistant professor at University of Pittsburgh鈥檚 Center for Pharmacogenetics. In 2005 Dr. Basu moved to 澳门六合彩资料鈥檚 department of Chemistry and Biochemistry. In 2013 Dr. Basu obtained an MBA just for fun!
Research
One of the major goals of the Basu lab is to understand structure-function relationship of nucleic acids, that adopt non-canonical structures. Of particular interest is studying a secondary non-canonical structure known as a G-quadruplex (GQ) that both DNA and RNA sequences rich in guanosine residues can adopt. The lab is interested in learning the role of such structures in regulation of fundamental cellular processes and strives to utilize such knowledge for development of therapeutics. Recently, we have expanded our interests to how CRSPR/Cas9 function is affected when placed in the vicinity of GQ structures and understanding of the role of RNA oxidation in various neurological disorders, especially multiple sclerosis and Parkinson鈥檚 disease as it relates to mitochondrial energy production. Finally, we study the 鈥淧ing-Pong鈥 cycle, a secondary biogenesis pathway for piRNAs. Overall, we want to contribute to the understanding and appreciation of the amazing versatility of RNA as a class of molecule.
Overall goal of my laboratory is to understand structure-function relationship of nucleic acids, which primarily adopt non-canonical structures. We are interested in learning the role of such structures in regulation of fundamental cellular processes, and utilize such molecules for therapeutic purposes.
We are particularly interested in studying a structural form known as G-quadruplex that both DNA and RNA sequences rich in guanosine residues can adopt. We intend to learn how the DNA G-quadruplexes regulate transcription and how the RNA G-quardruplexes can control translation. We will utilize biochemical and biophysical along with molecular biology and cell biology techniques to achieve these objectives.
