Dangerous liaisons: interplay between SWI/SNF, NuRD, and Polycomb in chromatin regulation and cancer

Genes & Development, Journal Year: 2019, Volume and Issue: 33(15-16), P. 936 - 959

Published: May 23, 2019

Changes in chromatin structure mediated by ATP-dependent nucleosome remodelers and histone modifying enzymes are integral to the process of gene regulation. Here, we review roles SWI/SNF (switch/sucrose nonfermenting) NuRD (nucleosome remodeling deacetylase) Polycomb system regulation cancer. First, discuss basic molecular mechanism remodeling, how this controls transcription. Next, provide an overview functional organization biochemical activities SWI/SNF, NuRD, complexes. We describe how, metazoans, balance these is central proper expression cellular identity during development. Whereas counteracts Polycomb, facilitates repression on chromatin. Finally, disruptions regulatory equilibrium contribute oncogenesis, new insights into biological functions Polycombs opening avenues for therapeutic interventions a broad range cancer types.

Genomic imprinting in plants—revisiting existing models

Genes & Development, Journal Year: 2020, Volume and Issue: 34(1-2), P. 24 - 36

Published: Jan. 1, 2020

Genomic imprinting is an epigenetic phenomenon leading to parentally biased gene expression. Throughout the years, extensive efforts have been made characterize marks underlying in animals and plants. As a result, DNA methylation asymmetries between parental genomes emerged as primary factor controlling status of many genes. Nevertheless, data accumulated so far suggest that this process cannot solely explain all In review, we revisit current models explaining regulation plants, discuss novel regulatory mechanisms could function independently establishment imprinting.
