This suggests that energetic stress is associated with elevated progesterone levels and may be the cause of the non-crop-raiding troop's lower reproductive output.
Cell dissociation, a pre-requisite for cell transplantation, leads to energetic stress, which is mediated by Akt dephosphorylation, downregulation of glucose uptake, and glycolysis.
"We rarely see bacula with sign of fractures, but it could easily occur," said Sonne, "especially when the bears also suffer from energetic stress [food shortage] due to the shrinking in sea ice extension".

Depending upon the energetic stress levels, cells undergo either autophagy or cell death.
Furthermore, no increase in levels of Caspase-7 was evident under energetic stress in cells with reduced IFI16 protein levels.
At present, it is not clear how ATM protein kinase is phosphorylated in response to the energetic stress.
However, in response to energetic stress, AMPKα is phosphorylated in an ATM-dependent and LKB1-independent manner [3].
Glucose restriction in cells increases the AMP/ATP ratio (energetic stress), which activates the AMPK/p53 pathway.
Of special interest, Mirouse and coworkers (2009) have shown that DG is required under conditions of energetic stress.
However, under severe glucose restriction, which results in higher energetic stress, autophagy may lead to cell death [22].
