Effects of therapeutic hypothermia on white matter injury from murine neonatal hypoxia-ischemia. Trends Endocrinol Metab. Identification of a lipokine, a lipid hormone linking adipose tissue to systemic metabolism. Palmitic acid treatment did not affect oxygen consumption in any of the conditions studied. In the next step, we investigated if palmitoleic acid could enhance FA beta-oxidation and oxygen consumption. White adipose tissue WAT stores triacylglycerol TAG and its metabolic feature involves lipogenesis and lipolysis, which are associated with changes in the volume of mature adipocytes. We next sought to more closely examine the effect of temperature upon mitochondrial function in mouse brain by examining the V max of CS and complexes I-V of the ETS at our two experimental temperatures Fig 2.
If mitochondria are incubated in an oxygraph apparatus (oxygen electrode) in an causes a sudden burst of oxygen uptake as the ADP is converted into ATP: The addition of an uncoupling agent (such as dinitrophenol or CCCP) leads to a.
The first of these determines the mitochondrial oxygen consumption associated ATP production directly, so allowing calculation of the ATP: O ratio. than UCP is believed to be the principal mitochondrial uncoupler . Liver mitochondrial ATP production and oxygen consumption values ATP production in tissue homogenates and calculation of effective P/O ratios.
Exercise efficiency is reduced by mitochondrial uncoupling in the elderly.
We hypothesized that the effect of temperature on mitochondrial function would scale predictably with temperature coefficient relationships Q 10 ; i.

In the equation, α is the absorption coefficient of O. Oxygen consumption, proton motive force (PMF) and proton leak are that allows dissipation of mitochondrial membrane potential (MMP) by uncoupling oxidative The overall goal of measuring mitochondrial oxygen consumption and proton. Example calculation based on concentrations in protocol.
Effects of cold on murine brain mitochondrial function
respirometry, mitochondrial oxygen affinities (1/P50) are reviewed with particular emphasis on the turnover effect the uncoupled respiration observed under control by ADP, as shown by relationships derived oxygen consumed, i.e. a diminished ADP/O2 flux . (B) Transition periods of ADP-injection and calculation of.

After adding n-heptane 1. Mitochondrial function particularly OXPHOS uncoupling and FA oxidation is considered a crucial factor to improve systemic insulin sensitivity [ 56575859 ]. Respiratory flux through the ETS was measured in permeabilized brain cells using a substrate-uncoupler-inhibitor-titration SUIT protocol described previously [ 1516 ].

|For respirometry data, significance was evaluated using a repeated-measures 2-way ANOVA to test for significant interactions between the two independent variables: i the substrate or inhibitor injected e.
Besides, this lipokine enhanced glucose uptake and GLUT4 content associated with AMPK activation in these cells, favoring cellular glucose utilization towards energy production [ 19 ].

Mitochondrial metabolism in hibernation: metabolic suppression, temperature effects, and substrate preferences.
These species also tend to be very tolerant of clinically relevant ischemic stresses in vivo and ex vivo and exhibit minimal oxidative stress and also avoid cell death pathway initiation during ischemia [ 811 — 13 ].
