DHA altered gene expression patterns in a similar way, as it changed the secretion of the respective proteins: IL-6 expression and, to a lesser extent, IL-1 β and IL-10 expression were augmented by DHA (at 20 μmol/L).
There are reasons to believe that changes in the secretion rate of saliva as well as changes in its protein and electrolyte composition promote the growth of micro-organisms associated with oral disorders.
Because of the rapid changes in the secretion of the hormones, particularly just before and after ovulation, when daily changes of 30 50% are usual, it is necessary to monitor ovarian activity frequently, ideally daily.
In addition, changes in the secretion of hormones regulated by the hypothalamus, such as prolactin, growth hormone and cortisol are found in patients affected by CH [7 9], and functional imaging studies showed the activation of hypothalamic gray matter during headache attacks [6, 10].
Additional studies in laboratory animals have demonstrated that BPA exposures in the womb are associated with abnormalities in adult female reproductive tissues and exposures shortly after birth have been associated with changes in the secretion of sex hormones from the brain and with the development of mammary (breast) cancer.
Aging was also associated with changes in the secretion activity of both Fp and Fr.
Changes in the secretion by fibroblasts of growth factor such as KGF throughout aging may partly explain the delayed wound healing observed in elderly people [54], [55].
Indeed, the changes in liver gene expression (Per1, Per2, GluT2 and PEPCK) observed after nocturnal light exposure are dependent on an intact input from the ANS and do not depend on changes in the secretion of corticosterone or melatonin.
Hippocampal slice cultures stimulated with UCB show no changes in the secretion profiles of the pro-inflammatory cytokines, interleukin-1β and tumor necrosis factor-α, or the propidium ioide uptake.
Significant changes in the secretion of gastric and intestinal peptides such as glucagon-like peptide-1 (GLP-1), ghrelin, and peptide YY have also been demonstrated following RYGB [7], [8].
