In what neurobiologist Jean-Pierre Changeux describes as the homeostatic regulation of mental processing (Physiology 238), a set of culturally-derived social rules, independent of any innate regulatory systems in the organism, determine many of the epigenetically developed (that is, environmentally-triggered) synaptic connections in the brain that we establish as we mature (250).
Identical twins are epigenetically identical at birth, but become increasingly epigenetically distinct as they become subject to different they become subject to different environmental influences.
Telomere length is epigenetically regulated by DNA and histone methylation of telomeric and subtelomeric regions, possibly by controlling the access of telomere-elongating proteins to telomeric regions.
Yamanaka's discovery altered the way scientists think about the processes that control activation and repression of genes: only three factors are sufficient to epigenetically "erase and re-mark" the entire genome.
Thus, these miRNAs were suppressive miRNAs for HCC that could be silenced epigenetically.
Typically, the substances acted epigenetically, which is to say they turned metastasis suppressor genes on or off.
Peters, like the wisdom approach to Jesus' creation theology, encourages us to think about theology and the doctrine of creation epigenetically and not archonically.
The primary way that cells 'play' the genes epigenetically is through a process called DNA methylation, which adds little chemical flags on the DNA sequence that affect gene activity.
During this process, the NF-[kappa]B-mediated inflammatory response activates a positive feedback loop, which maintains a stable epigenetically transformed state for many generations, even in the absence of the initial signal that started the process.
Wnt inhibitory factor 1 is epigenetically silenced in human osteosarcoma, and targeted distruption accelerates osteosarcomagenesis in mice.
