Recent evidence also suggests that epigeneticmodification of gene expression may be a key factor and that this has the potential to produce transgenerational effects. As with many examples of epigeneticmodification, ' reversions ' occur sporadically that restore the standard phenotype. Regions of parental-allele-specific epigeneticmodification such as this are associated with genes regulated by genomic imprinting and expressed from only one parental chromosome. However, these effects are also likely to involve epigeneticmodification of the genome. Another cause of difference between monozygotic twins is epigeneticmodification, caused by differing environmental influences throughout their lives.

Studies have suggested other signalling pathways that could affect epigenetic modifications and therefore provide suitable therapeutic targets. Epigenetic modifications during oocyte growth correlates with extended parthenogenetic development in the mouse. It has been shown that epigenetic modifications can also regulate telomere length through the modulation of the chromatin environment of the telomeres themselves. In vitro fertilization causes epigenetic modifications to the onset of gene expression from the zygotic genome in mice. Here we examine the human orthologues of mouse genes imprinted only in the placenta, assaying allele-specific expression and epigenetic modifications. In mature oligodendrocytes, the expression of inhibitory molecules is silenced by additional epigenetic modifications, including histone methylation and chromatin compaction. Data establishing epigenetic processes as important regulators of senescence and tumourigenesis also suggest that such epigenetic modifications may be useful as prognostic markers. Environmental cues, including dietary components, present in the in utero environment can induce significant changes in the expression of the genome through epigenetic modifications.
