Defining the role of microRNA in chronic pain development following trauma exposure (Linnstaedt, PI)

 

MicroRNA are small post-transcriptional regulators of gene expression, which have been shown to play critical roles in a variety of diseases, from cancer to heart disease.  However, their role in post-trauma pain development is poorly understood.  This study aims to show a) that microRNA are important mediators in the transition from acute to chronic pain following trauma such as motor vehicle collision and sexual assault and b) that microRNA regulate a number of gene-transcripts that are integral to pain pathogenesis.  The ultimate goal of this research is to define novel targets for therapeutic intervention.  Sarah Linnstaedt, PhD is PI of this study.
