(H,I) Effect of MPC inhibition on adipocyte fuel preference towards fatty acid. (H) Schematic representation of metabolite tracing using [U-13C16] palmitate. (I) [U-13C16] palmitate tracing in fully differentiated primary brown adipocytes treated with 5 µM UK5099 or vehicle for 24 h. Data shows mole percent enrichment (MPE) of isotope labeled substrate into respective metabolite.
