Starting from these data, it is reasonable to conclude that one effect of DJ-1 inactivation by genetic alterations is to impair its prevention of oxidative stress, thus exposing dopaminergic neurons to exogenous or endogenous deleterious stimuli.
This report suggests that the absence of ATX-3 activates the DAF-16 pathway leading to an overexpression of molecular chaperones, which yields knockout animals with an improved capacity for dealing with deleterious stimuli.
Since plants are immobile, they face a myriad of possible deleterious stimuli without any possibility to depart.
During the development of peripheral nerve damage, the amount of endoneurial fluid may increase at the site due to irritation or other deleterious stimuli (4).
Autophagy is a response by eukaryotic cells to a number of deleterious stimuli, and it plays a critical role in the regulation of survival of H. pylori.
AMPK has pleiotrophic effects that may be anti-atherogenic, including the suppression of reactive oxygen species production induced by deleterious stimuli, such as hyperglycemia or high levels of free fatty acids [ 14, 31].
Physical well-being is achieved through the instrumental goals of stimulation [activities producing arousal, e.g., mental and sensory stimulation, physical effort and (competitive) sports–although prolonged physical effort can become unpleasant] [ 2, 5- 7] and comfort (absence of deleterious stimuli, such as fear, pain, hunger, and thirst).
Activation or deactivation of genes in response to various deleterious environmental stimuli may be important in the development of common complex diseases [ 3, 4].
On the contrary, persistent or excessive inflammatory stimuli may have deleterious effects, by decreasing EPC circulating numbers [ 28, 29].
Dysfunctional mitochondria may originate from deleterious effects of specific toxic stimuli or by a series of fusion fission events that characterize the mitochondrial life cycle (12– 12).
