Through this work Dr. Gunaratne’s group has also established a framework for defining unique microRNA-regulated gene signatures that can be used for personalizing cancer treatments based on underlying genetic mutations in tumors as defined by Whole Exome or Whole Genome sequencing (WES or WGS). To rapidly translate their findings into clinical practice Dr. Gunaratne co-founded NEXTmiRNA Technologies a company dedicated to harnessing tumor suppressor microRNAs as the Next Generation cancer drugs – acting as circuit breakers of multiple oncogenic pathways driving cancer.
