  2. 6. Regulation of chloroplast gene expression in higher plants

    Author : Anna Furo Tullberg; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein tyrosine kinase; plastoquinone pool; redox; Pisum sativum; Sinapis alba; petB; psaB; chloroplast; gene expression; Physiological biophysics; Växtfysiologi; light harvesting complex II;

    Abstract : Chloroplast gene expression is regulated by developmental and environmental signals. It has been proposed that there is a direct coupling between electron transport in biological membranes and gene expression (J. F. Allen, 1992, Biochim. READ MORE

  4. 7. Epigenetic Regulation of Higher Order Chromatin Conformations and Gene Transcription

    Author : Anita Göndör; Reinald Fundele; Thomas Graf; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Genomic imprinting; Chromatin; Epigenetics; Cancer; Developmental biology; Utvecklingsbiologi;

    Abstract : Epigenetic states constitute heritable features of the chromatin to regulate when, where and how genes are expressed in the developing conceptus. A special case of epigenetic regulation, genomic imprinting, is defined as parent of origin-dependent monoallelic expression. READ MORE

  5. 8. The Epigenetics of Gene Transcription and Higher Order Chromatin Conformation

    Author : Vijay Kumar Tiwari; Rolf Ohlsson; Terumi Kohwi-Shigematsu; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; DNA-protein interactions; Nuclear organization; Transcriptional regulation; Higher order chromatin conformations; Epigenetic reprogramming; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi;

    Abstract : It is becoming increasingly clear that long-range control of gene expression is mediated through direct physical interactions between genes and regulatory elements, either intra- or interchromosomally. In addition to transcriptional initiation, formation of active chromatin hubs seem to be crucial for increased transcriptional efficiency as well as insulation from neighbouring heterochromatic environment.

  6. 9. Epigenetic Regulation of the H19 Chromatin Insulator in Development and Disease

    Author : Claes Holmgren; Rolf Ohlsson; Tomas Ekstöm; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Developmental Biology; Miljömedicinsk utvecklingsbiologi;

    Abstract : The coordinated regulation of gene expression must be tightly controlled for normal development to occur. In mammals, this issue is further complicated by the requirement of both the maternal and paternal genomes for normal development, reflecting the fact that a subset of genes are monoallelically expressed depending on parental inheritance, a phenomenon known as genomic imprinting.

  7. 10. Long Noncoding RNA Mediated Regulation of Imprinted Genes

    Author : Faizaan Mohammad; Chandrasekhar Kanduri; Kristian Helin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Genomic imprinting; noncoding RNA; epigenetics; chromatin; DNA methylation; Developmental biology; Utvecklingsbiologi; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : Genomic imprinting is an epigenetic phenomenon that causes a subset of mammalian genes to be expressed from only one allele in a parent-of-origin manner. The defects in the imprinting regulation result in disorders that affect development, growth and metabolism. READ MORE
