Ablation of the HNF4α gene in fetal mouse colon resulted in failure to produce normal crypts and influencing the expression of several intestinally expressed genes [ 27].
Water temperature and dietary protein play an important role in influencing the expression of somatotropic gene.
For herbal extracts, several mechanisms of interference with the production or activity of eicosanoids have been described including the regulation of enzyme expression [8 10] and enzyme activity [11], but also by influencing the expression of eicosanoid receptors [8, 12].
"While we have discovered an association between these genes and body size in childhood we need to carry out further studies to establish whether influencing the expression of these genes by altering epigenetic patterns is indeed a trigger to obesity".
Here, we explore the role of the maternal environment in influencing the expression of a novel resource-use phenotype.
The overall goal of our study was to determine the proximate mechanisms underlying a maternal effect influencing the expression of resource polymorphism in S. multiplicata.
By influencing the expression of novel resource-use phenotypes, maternal effects may play a largely underappreciated role in the origins of novelty.
VDRE is shown to have subtle sequence differences and different HLA alleles may have different VDRE sequences in their promoter regions influencing the expression of HLA alleles [26].
Another possibility would be that these linkage disequilibrium blocks may contain regulatory variants which are influencing the expression level of these genes.
The nucleosomes formed on CG containing sequences may well have an "epigenetic" property [16], their stability and positions being modulated by the CG methylation, this way possibly influencing the expression level of genes located nearby.
The results of this study, both in vivo and in vitro, clearly demonstrate that all doses of DEHP strongly impair oocyte maturation and ovulation by influencing the expression of factors involved in these processes.
