  2. 1. Jack of all trades, master of none : the multifaceted nature of H3K36 methylation

    Author : Henrik Lindehell; Jan Larsson; Anders Byström; Peter B. Becker; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; H3K36; histone methylation; dosage compensation; chromosome-specific gene regulation; transposable elements; PIWI piRNA biosynthesis; Set2; Ash1; NSD; Histone 3.3; post-translational modifications; histone modifications; epigenetics; proximity ligation assay; Drosophila; Genetics; genetik; molekylärbiologi; Molecular Biology; Biopharmaceutics; biofarmaci;

    Abstract : Post-translational modifications of histones enable differential transcriptional control of the genome between cell types and developmental stages, and in response to environmental factors. The methylation of Histone 3 Lysine 36 (H3K36) is one the most complex and well-studied histone modifications and is known to be involved in a wide range of molecular processes. READ MORE

  4. 2. Expression and function of Suppressor of zeste 12 in Drosophila melanogaster

    Author : Sa Chen; Åsa Rasmuson-Lestander; Jan Larsson; Mattias Mannervik; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Epigenetics; histone; polycomb; Drosophila; Suppressor of zeste 12; Genetics; Genetik; genetik; Genetics;

    Abstract : The development of animals and plants needs a higher order of regulation of gene expression to maintain proper cell state. The mechanisms that control what, when and where a gene should (or should not) be expressed are essential for correct organism development. READ MORE

  5. 3. Biosynthesis and physiological functions of N-acyl amino acids

    Author : Dominik Paweł Waluk; Mary C. Hunt; David Merkler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molekylärgenetik; Molecular Genetics;

    Abstract : N-acyl amino acids are lipid signalling molecules that have recently been identified in biological systems. These lipids are structurally related to the endocannabinoids, although they do not activate cannabinoid receptors. READ MORE

  6. 4. Epigenomic landscape of Arabidopsis thaliana

    Author : Trejo Minerva; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The basal unit of information storage in the cell is at the level of the DNA sequence. Dynamic packaging of DNA into chromatin allows additional regulatory layers. Two pairs of each histones H3, H4, H2A and H2B constitute an octamer around which about 146 base pairs of DNA are wrapped to build the basic unit of chromatin: the nucleosome. READ MORE

  7. 5. Methyltransferase Ash1, histone methylation and their impact on Polycomb repression

    Author : Eshagh Dorafshan Esfahani; Yuri B. Schwartz; Jan Larsson; Dale Dorsett; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Trithorax Group proteins; Polycomb Group proteins; PRC1; PRC2; PRE; histone methylation; histone ubiquitylation; Ash1; SET domain; H3K36; H3K27; Drosophila;

    Abstract : Antagonistic interactions between Polycomb Group (PcG) and Trithorax Group (TrxG) proteins orchestrate the expression of key developmental genes. Distinct maternally loaded repressors establish the silenced state of these genes in cells where they should not be expressed and later PcG proteins sense whether a target gene is inactive and maintain the repression throughout multiple cell divisions.
