A greater understanding of the dynamics that mediate an individual's predisposition to stress-induced neuropathology has major human health benefits and is an important area of research.
Importantly, such a genetic predisposition to stress-induced breast cancer development is supported by the observation that a highly polymorphic dinucleotide CA repeat (D5S207), suspected to occur in linkage disequilibrium with a polymorphism within the GR locus, is associated with an increase in breast cancer risk [ 69].
The hypothesis is that T2D and MetS are not merely disorders affecting glucose levels, lipid levels, and blood pressure, rather they are complex disorders characterized by increased predisposition to stress-related hyperactivity and abnormal psychological traits leading to abnormal behavioral and compensatory mechanisms.
These data suggest that both early life stress (MS) and a genetic predisposition (WKY) to stress affect the expression of key sentinels of the innate immune system which may have direct relevance for the molecular pathophysiology of IBS.
It is not known whether the changes in the cortical responses to hypoglycemia are part of the hypoglycemia-induced syndrome of unawareness and counterregulatory deficit, in which case they should be reversible, or whether they reflect a predisposition to respond to stress in this manner.
33 While some subjects thrive and some break down under similar adverse circumstances due to neuroendocrine stress-related psychopathology, differential genetic predisposition to neuroendocrine stress response is expected.
In the case of Muse-AT cells, CXCL2 is expressed 770 folds higher than in neighboring ASCs, which could therefore explain their genetic predisposition to cellular stress resistance [22].
It has also been shown that genetic predisposition to oxidative stress may determine susceptibility to glaucoma [ 18] and the response to antioxidants as ocular hypotensive agents seems to be influenced by genetic background.
One example is the link between gestational stress and subsequent anxiety in offspring [ 17], where the effects are thought to be mediated by exposure to glucocorticoids in utero, but for which the association might be accounted for by genetic pathways, that influence both maternal predisposition to experiencing stress and offspring anxiety.
