Epigenetic stochasticity
WebIn light of recent whole-genome screens for novel metastable epialleles, we point out the need to reassess their biological relevance in multi-generational studies and we highlight their value as a model to study repeat element silencing as well as the mechanisms and consequences of mammalian epigenetic stochasticity. WebMar 16, 2012 · Epigenetic Stochasticity in Development and Cancer When discussing the role of epigenetic mechanisms in cancer, one immediately considers abnormal methylation resulting in the inappropriate regulation of oncogenes and tumor suppressor genes.
