Epigenetics and genomic imprinting
WebGrossniklaus’ group made seminal contribution to understanding the epigenetic mechanisms that control of seed development, in particular gene regulation by Polycomb-group proteins and genomic imprinting. Raffaella Santoro is Professor of Epigenetics and Chromatin Dynamics at the University of Zurich. WebImprinting defects can involve isolated or multilocus epigenetic changes that may have no evident genetic cause, or imprinting disruption can be traced back to alterations of cis-acting elements or trans-acting factors that control the establishment, maintenance and erasure of germline epigenetic imprints.

This process is initiated in the germline, and the parental epigenetic memories can be maintained following fertilization and induce further allele-specific transcription and chromatin modifications of single or multiple neighboring …

There are two well-characterised features that are treated differently during epigenetic reprogramming; imprinted genes and repeats. WebEpigenetics is an area of increasing importance in human and medical genetics because epigenetic silencing of gene expression is a phenomenon that explains such widely diverse phenomena as X inactivation; genomic imprinting in well-known syndromes like Prader–Willi, Angelman, and Beckwith–Wiedemann; and carcinogenesis.
