Mitochondrial Proton Leak Compensates for Reduced Oxidative Power during Frequent Hypothermic Events in a Protoendothermic Mammal, Echinops telfairi
The lesser hedgehog tenrec (Echinops telfairi) displays reptile-like thermoregulatory behavior with markedly high variability in body temperature and metabolic rate. To understand how energy metabolism copes with this flexibility, we studied the bioenergetics of isolated liver mitochondria from cold (20°C) and warm (27°C) acclimated tenrecs. Different acclimation temperatures had no impact on m...
متن کاملBrown fat in a protoendothermic mammal fuels eutherian evolution
Endothermy has facilitated mammalian species radiation, but the sequence of events leading to sustained thermogenesis is debated in multiple evolutionary models. Here we study the Lesser hedgehog tenrec (Echinops telfairi), a phylogenetically ancient, 'protoendothermic' eutherian mammal, in which constantly high body temperatures are reported only during reproduction. Evidence for nonshivering ...
متن کاملMitochondrial proton leak and the uncoupling proteins.
An energetically significant leak of protons occurs across the mitochondrial inner membranes of eukaryotic cells. This seemingly wasteful proton leak accounts for at least 20% of the standard metabolic rate of a rat. There is evidence that it makes a similar contribution to standard metabolic rate in a lizard. Proton conductance of the mitochondrial inner membrane can be considered as having tw...
متن کاملOrganization of sensory cortex in a Madagascan insectivore, the tenrec (Echinops telfairi).
We identified subdivisions of somatosensory cortex, and the borders and extents of auditory and visual cortex in Madagascan tenrecs (Echinops telfairi) by using microelectrode recording techniques and cortical myeloarchitecture. There was evidence for three distinct somatosensory fields. The primary somatosensory area (S1) contained an orderly representation of the contralateral body surface th...
متن کاملMitochondrial proton leak in obesity-resistant and obesity-prone mice.
We quantified uncoupling proteins (UCPs) in molar amounts and assessed proton conductance in mitochondria isolated from interscapular brown adipose tissue (IBAT) and hindlimb muscle [known from prior work to contain ectopic brown adipose tissue (BAT) interspersed between muscle fibers] of obesity-resistant 129S6/SvEvTac (129) and obesity-prone C57BL/6 (B6) mice under conditions of low (LF) and ...
