  2. 1. Epigenetic Regulation by Noncoding RNA

    Author : Tanmoy Mondal; Chandrasekhar Kanduri; Jérôme Cavaillé; Uppsala universitet; []
    Keywords : Genomic Imprinting; Noncoding RNA; Epigenetics; DNA methylation; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : High throughput transcriptomic analyses have realized us with the fact that eukaryotic genome encodes thousands of noncoding RNAs (ncRNAs) with unknown function. In my thesis, I sought to address epigenetic regulation of transcription by ncRNA using the Kcnq1 imprinted cluster as a model system. READ MORE

  4. 2. Epigenetic Regulation of Genomic Imprinting and Higher Order Chromatin Conformation

    Author : Gholamreza Tavoosidana; Rolf Ohlsson; Job Dekker; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Epigenetic; Imprinting; Chromatin; CTCF; H19 ICR; 4C; Utvecklingsbiologi; Biology; Biologi;

    Abstract : The genetic information encoded by the DNA sequence, can be expressed in different ways. Genomic imprinting is an epigenetic phenomenon that results in monoallelic expression of imprinted genes in a parent of origin-dependent manner. Imprinted genes are frequently found in clusters and can share common regulatory elements. READ MORE

  5. 3. Enzymatic Regulation of Steroidogenesis and Nuclear Receptor Activation : Special Focus on Vitamin D and Sex Hormones

    Author : Johan Lundqvist; Kjell Wikvall; Maria Norlin; Magnus Ingelman-Sundberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenal steroidogenesis; CYP7B1; vitamin D; calcitriol; enzymatic regulation; transcriptional regulation; CYP21A2; aromatase; sex hormone; estrogen; androgen; nuclear receptor; Pharmaceutical biochemistry; Farmaceutisk biokemi; Farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Abstract : Enzyme-catalyzed reactions are important to regulate steroidogenesis and nuclear receptor activation. The present investigation examines the role of steroid metabolism catalyzed by CYP7B1 for regulation of hormone receptor activation and the effects of vitamin D on enzymatic regulation of steroidogenesis.

  6. 4. Genetic and Genomic Analysis of Transcriptional Regulation in Human Cells

    Author : Mehdi Motallebipour; Claes Wadelius; Gunnar Westin; Dirk Schübeler; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transcription; ChIP-chip; ChIP-seq; genome-wide; transcription factors; microsatellite; epigenetic; Medical genetics; Medicinsk genetik;

    Abstract : There are around 20.000 genes in the human genome all of which could potentially be expressed. However, it is obvious that not all of them can be active at the same time. Thus, there is a need for coordination achieved through the regulation of transcription. READ MORE

  7. 5. Epigenetic regulation of transcription and cellular development

    Author : Farzaneh Shahin Varnoosfaderani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Epigenetic machinery can regulate different biological processes via different mechanisms. In this thesis, we explore the effects of the epigenetic system on transcription and how it can differ during cellular development in different human cell lines models, with focus on hematopoiesis.
