What would you highlight as the most important finding of this paper?
The conventional view of adipocyte thermogenesis activation is through adrenergic receptor (encoded by ADRB3) stimulation, signaling through cyclic AMP, and thermogenesis by uncoupling protein 1 (UCP1). We find that activation of the alpha-adrenergic receptor (encoded by ADRA1A) potentiates thermogenesis by the cyclic AMP-UCP1 axis by triggering a parallel pathway of thermogenesis called the Futile Creatine Cycle.
How is this finding helping to advance the science of cancer?
Since thermogenesis requires the combustion of metabolic fuels, activating brown fat thermogenesis may compete for nutrients that cancer cells use to promote their proliferation.
