Plasma adiponectin concentrations were quantified before and during cold exposure.
Sympathetic nerve activation is recognized at the adipose tissue level during cold exposure.
Consistent with that, its activity pattern is opposite to that of VRN1--going down, not up, during cold exposure.
Accidental hypothermia is defined as an unintentional decrease in core temperature during cold exposure in individuals without intrinsic thermoregulatory dysfunction [1].
In study 2, adiponectin levels increased by approximately 70% during cold exposure after both low- and high-CHO diets (effect of time, P <.05).
This is underlined by our finding that UCP-3 protein expression was not upregulated during cold exposure.
This suggested that the shallow heterothermia phases observed in adult mouse lemurs allowed water savings during cold exposure.
However, aging was associated with increased levels of energy expenditure during cold exposure, in concomitance with impaired energy balance.
In fact, water was available ad libitum what maybe did not contribute to evidence the role of heterothermia in the reduction of water turnover during cold exposure.
All the zucp isoforms were expressed in every region of the brain, and only the zucp1 mRNA expression was not induced during cold exposure.
As shown in our concept in Fig. 16, we inferred that the excess of ROS or lipid peroxidation products accumulating in fish brain during cold exposure up-regulate some ucp genes.
