Since IPF fibroblasts have been reported to be epigenetically modified (reviewed in ref. 8), we next examined the role of mTOR signaling in IPF-derived fibroblasts.
Moreover, the base sequence can also dictate the relative probability that a region of the genome will be epigenetically modified.
Importantly, BCG-educated HSCs generate epigenetically modified macrophages that provide significantly better protection against virulent M. tuberculosis infection than naïve macrophages.
In this review we discuss microRNA genes that are epigenetically modified in cancer cells, and the role that microRNAs themselves can have as chromatin modifiers.
However, we recently showed that, genome-wide, human TEs can also be epigenetically modified in a manner consistent with their ability to regulate host genes.
All this suggests it is worth investigating the idea that epigenetically modified sperm may be a previously unrecognised source of disease.The other point worth noting is that, although some epigenetic modification takes place when sperm cells form (shortly before they are ejaculated), much of it happens early in embryonic development, when the progenitors of those cells come into being.
Imprinted genes are epigenetically modified genes whose expression is determined according to their parent of origin.
A sequencing method can discriminate epigenetically modified cytosine nucleotides within embryonic stem cell DNA.
The pluripotency-related genes in reprogrammed HFFs were also expressed at higher levels than epigenetically modified HFFs or hESC extract-treated HFFs alone.
XYY and XXX ES lines were absent, suggesting cell death related either to insufficient X-chromosomal gene dosage (XYY) or to inheritance of an epigenetically modified X chromosome (XXX).
Histones can be epigenetically modified by site-specific combinations of phosphorylation, acetylation and methylation, which correlate with specific biological readouts, such as transcriptional activation or repression, chromatin remodelling or stabilization [32].
