Lysine-specific demethylase 1 regulates differentiation onset and migration of trophoblast stem cells. Zhu D, Hölz S, Metzger E, Pavlovic M, Jandausch A, Jilg C, Galgoczy P, Herz C, Moser M, Metzger D, Günther T, Arnold SJ, Schüle R Propagation and differentiation of stem cell populations are tightly regulated to provide sufficient cell numbers for tissue formation while maintaining the stem cell pool. Embryonic parts of the mammalian placenta are generated from differentiating trophoblast stem cells (TSCs) invading the maternal decidua. Here w... |
Histone modifications at the blastocyst Axin1(Fu) locus mark the heritability of in vitro culture-induced epigenetic alterations in mice. Fernandez-Gonzalez R, Ramirez MA, Pericuesta E, Calle A, Gutierrez-Adan A For epigenetic phenotypes to be passed on from one generation to the next, it is required that epigenetic marks between generations are not cleared during the two stages of epigenetic reprogramming: mammalian gametogenesis and preimplantation development. The molecular nature of the chromatin marks involved in these... |
Phosphorylation of histone H3T6 by PKCbeta(I) controls demethylation at histone H3K4. Metzger E, Imhof A, Patel D, Kahl P, Hoffmeyer K, Friedrichs N, Müller JM, Greschik H, Kirfel J, Ji S, Kunowska N, Beisenherz-Huss C, Günther T, Buettner R, Schüle R Demethylation at distinct lysine residues in histone H3 by lysine-specific demethylase 1 (LSD1) causes either gene repression or activation. As a component of co-repressor complexes, LSD1 contributes to target gene repression by removing mono- and dimethyl marks from lysine 4 of histone H3 (H3K4). In contrast, durin... |
