As reported earlier in similar experiments (Fridell et al., 2005), the level of uncoupling may be important for lifespan effects.
Of note, the increased O2− production in MAECS of Lacz-infected DOCA-salt-treated mice was decreased significantly by PEG SOD or apocynin or L-NNA, suggesting mitochondria, NADPH oxidase and eNOS uncoupling may be the main source of O2−.
ROS production is very sensitive to mild uncoupling in isolated Drosophila mitochondria (Miwa et al., 2003) and mild mitochondrial uncoupling may be neuroprotective.
Therefore, targeting mitochondrial uncoupling may be considered as a novel treatment strategy for cancer.
We did not have the data necessary to calculate ventriculoarterial uncoupling, which may be relevant to cardiac dysfunction in sepsis.
So far, the challenge in animal science has been that resistance and tolerance are difficult to uncouple, and the traits may be confounded in trait recording.
Proton leakage, which partially uncouples the oxidative phosphorylation, may be associated with the presence of UCPs and ANT (Andreyev et al., 1989; Brand and Esteves, 2005; Krauss et al., 2005).
Nonetheless, evidence that β-catenin phosphorylated at S33/37/T41 incompletely overlaps with β-catenin phosphorylated at T41/S45 raises the possibility that phosphorylation of β-catenin at the CK1α site may be spatially uncoupled from phosphorylations within the GSK-3β cassette.
This indicates that in the colon, it may be difficult to uncouple the anti-cancer and calcium homeostatic effects of vitamin D. Although, in other studies we show that some vitamin D partial antagonists will activate the vitamin D receptor in cells which express high levels of activated β-catenin (cancer cells) but not in normal cells and may have the potential to do this [2].
The advantage may be that miRNA-guided translational repression can uncouple the ongoing translation.
