Thank you for this comprehensive contribution to our understanding of pre-hibernation remodeling in the Syrian hamster. Our studies in the arctic ground squirrel suggest that pre-hibernation remodeling and torpor onset involves increased sensitivity of A1 adenosine receptors with a subsequent inhibition of thermogenesis. See Olson et al., Circannual rhythm in body temperature, torpor, and sensitivity to A₁ adenosine receptor agonist in arctic ground squirrels. J Biol Rhythms. 2013 Jun;28(3):201-7. doi: 10.1177/0748730413490667. PubMed PMID: 23735499; PubMed Central PMCID: PMC4423736.
