Whiteman J, Harlow H, Durner G, Regehr E, Rourke B, Robles M, et al.
Conserv Physiol
. 2017 Aug;
5(1):cox049.
PMID: 28835844
When reducing activity and using stored energy during seasonal food shortages, animals risk degradation of skeletal muscles, although some species avoid or minimize the resulting atrophy while experiencing these conditions...

J Exp Biol
. 2013 Sep;
216(Pt 24):4678-90.
PMID: 24072796
Deep hibernators such as golden-mantled ground squirrels (Callospermophilus lateralis) have multiple challenges to cardiac function during low temperature torpor and subsequent arousals. As heart rates fall from over 300 beats...

J Mol Evol
. 2011 Sep;
73(3-4):74-93.
PMID: 21915654
Synonymous codon usage bias is a broadly observed phenomenon in bacteria, plants, and invertebrates and may result from selection. However, the role of selective pressures in shaping codon bias is...

Meyer C, Willershauser M, Jastroch M, Rourke B, Fromme T, Oelkrug R, et al.
Am J Physiol Regul Integr Comp Physiol
. 2010 Sep;
299(5):R1396-406.
PMID: 20826705
We compared maximal cold-induced heat production (HPmax) and cold limits between warm (WA; 27°C), moderate cold (MCA; 18°C), or cold acclimated (CA; 5°C) wild-type and uncoupling-protein 1 knockout (UCP1-KO) mice....

Nowell M, Choi H, Rourke B
J Comp Physiol B
. 2010 Aug;
181(1):147-64.
PMID: 20703484
During hibernation, ground squirrels (Spermophilus lateralis) show unusually altered expression of skeletal muscle myosin heavy-chains. Some muscle groups show transitions from fast to slower myosin isoforms despite atrophy, which are...

Am J Physiol Regul Integr Comp Physiol
. 2009 Jun;
297(3):R578-86.
PMID: 19553499
We performed 2 wk of mechanical overload by synergist ablation on plantaris muscles from a small rodent hibernator, Spermophilus lateralis. While this muscle displays prominent myosin heavy-chain (MyHC) isoform shifts...

Eme J, Owerkowicz T, Gwalthney J, Blank J, Rourke B, Hicks J
J Comp Physiol B
. 2009 Jun;
179(8):921-31.
PMID: 19533151
The oxygen transport system in mammals is extensively remodelled in response to repeated bouts of activity, but many reptiles appear to be 'metabolically inflexible' in response to exercise training. A...

J Comp Physiol B
. 2006 Jun;
176(7):709-20.
PMID: 16758215
Hibernating mammals have the remarkable ability to withstand long periods of fasting and reduced activity with dramatic maintenance of skeletal muscle function and protein composition. We investigated several hindlimb muscles...

PMID: 16373434
Oleoylethanolamide (OEA) is an endogenous lipid mediator that inhibits feeding in rats and mice by activating the nuclear receptor peroxisome proliferator-activated receptor-alpha (PPAR-alpha). In rodents, intestinal OEA levels increase about...

PMID: 15744290
Oxygen consumption by carnivorous reptiles increases enormously after they have eaten a large meal in order to meet metabolic demands, and this places an extra load on the cardiovascular system....
