Ravindra Singh, Professor and Salsbury Chair, Biomedical Sciences.
Singh group works on the interface of fundamental and translational biology. General interest of his group has been to understand the mechanism of alternative splicing, a vital process that increases the coding potential of genome in all higher eukaryotes. Alternative splicing is also associated with a growing number of diseases including neurological and neuromuscular disorders, cardiovascular disorders and cancer. Particular focus of his group has been to understand the molecular basis of Spinal Muscular Atrophy (SMA), a debilitating genetic disease of infants and children. His award-winning discovery relates to finding a unique regulatory element located within the non-coding region (or intron) of Survival Motor Neuron (SMN) gene. He has termed this novel regulatory element as Intronic Splicing Silencer N1, which is abbreviated as ISS-N1. Currently, his group is working on the mechanistic details of how ISS-N1 could be used as a therapeutic target. His other interests include RNA-protein interactions and isolation of RNA aptamers as detection and diagnostic tools.
