Influence of Histone Variants on Chromatin Structure and Metabolism (Markus Buschbeck)

In this episode of the Epigenetics Podcast, we sat down with Marcus Buschbeck, Group Leader at the Josep Carreras Leukaemia Research Institute in Barcelona, to talk about his work on the histone variant macroH2A, its role in metabolism and how it contributes to the regulation of chromatin structure.\n\xa0\nHistone variants equip chromatin with unique properties and show a specific genomic distribution. The histone variant macroH2A is unique in having a tripartite structure consisting of a N-terminal histone-fold, an intrinsically unstructured linker domain and a C-terminal macro domain. Recent discoveries show that macroH2A proteins have a major role in the nuclear organization which has the potential to explain how these proteins can act as tumor suppressors, promoters of differentiation and barriers to somatic cell reprogramming.\n\xa0\nWe discuss these topics, the mission of the Josep Carreras Leukaemia Research Institute, and much more in this episode.\n\xa0\xa0\nReferences\nhttp://www.carrerasresearch.org/Buschbeck_Marcus\nMarcus Buschbeck, Iris Uribesalgo, \u2026 Luciano Di Croce (2009) The histone variant macroH2A is an epigenetic regulator of key developmental genes (Nature Structural & Molecular Biology) DOI: 10.1038/nsmb.1665\xa0\nJulien Douet, David Corujo, \u2026 Marcus Buschbeck (2017) MacroH2A histone variants maintain nuclear organization and heterochromatin architecture (Journal of Cell Science) DOI: 10.1242/jcs.199216\xa0\nMelanija Posavec Marjanovi\u0107, Sarah Hurtado-Bag\xe8s, \u2026 Marcus Buschbeck (2017) MacroH2A1.1 regulates mitochondrial respiration by limiting nuclear NAD+ consumption (Nature Structural & Molecular Biology) DOI: 10.1038/nsmb.3481\nOriana Lo Re, Julien Douet, \u2026 Manlio Vinciguerra (2018) Histone variant macroH2A1 rewires carbohydrate and lipid metabolism of hepatocellular carcinoma cells towards cancer stem cells (Epigenetics) DOI: 10.1080/15592294.2018.1514239\nContact\nhttps://twitter.com/activemotif\nhttps://twitter.com/epigenetics_pod\nhttps://www.linkedin.com/company-beta/35651/\nhttps://www.facebook.com/ActiveMotifInc/\npodcast@activemotif.com
