Project Description/Abstract

This project will focus on harnessing the power of bacteria to generate heat by turning on and off gene expression and ultimately overexpressing one of the uncoupling proteins involved in deregulating oxidative phosphorylation.

Members of the TRP family, specifically TRPM8 and TRPV4, regulate oxidative phosphorylation via uncoupling protein 1 (UCP1). TRPM8 positively regulates UCP1 and TRPV4 negatively regulates it via inhibition of PGC1-alpha. Uncoupling protein 1 is a major source of thermogenesis, and overexpression of this protein has provided hope for treating obesity and other metabolic conditions. However, the thermogenesis potential of this protein may itself be used as a local heating source, if overexpressed to an appropriate extent. We propose seeding bacteria in a cell and overexpressing UCP1 via TRPV4 inhibition and TRPM8 activation. We believe that this will increase heat production in bacteria, which can be used in a variety of applications.
