For NH3+, an additional acid-mediated contribution had to be included to explain the slight increase of the exchange rate at low pH.
However, this ROS-mediated contribution to hyporesponsiveness requires fairly prolonged ROS exposure since 15-day anti-oxidant treatment does not improve reactivity.
These data suggest that the ROS-mediated contribution to hyporeactivity requires fairly prolonged ROS exposure, and, thus, ROS is clearly not the major factor imposing hyporeactivity on NCD4 cells upon prolonged peripheral residence.
We show that Panx1 mediates endothelial contribution to the adrenergic-induced contractions, thereby modulating vascular tone.
Might the secretory ability of cells within the female reproductive system be linked to their reported high propensity to DNA damage, and so directly mediate their contribution to ovarian cancer?
One consequence of astrocyte dysfunction may be loss of their glutamate transport capacity, which has been widely described in ALS and may underlie glutamate receptor mediated (excitotoxic) contributions to MN injury.
In view of the metabolic links between MTA and SAMe, we measured SAMe levels in control and MTA-treated Mdr2−/− mouse liver but did not observe major differences, indicating that MTA effects were not likely mediated through its potential contribution to the SAMe pool.
The physiological mechanisms that mediates stress and their contribution to illness and manifest disease is not fully understood.
This is in direct contrast to observations made regarding other multidrug binding proteins such as EmrE, MdfA, and BmrR, for which acidic residues have been shown to directly mediate a significant energetic contribution to ligand binding (11– 11).
These effects may be mediated by PFC cerebellum contributions to executive processing.
While we surmise that the domains do not independently mediate membrane interactions, their contribution to membrane-associated configurations, such as multi-domain trans-membrane channels, cannot be formally ruled out.
