  1. 1. Studies of genes involved in regulating flowering time in Arabidopsis

    Författare :Maria Svensson; Högskolan i Skövde; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; flowering time; fold recognition; GA biosynthesis; promoter trapping; RNA-binding; T-DNA tagging; Biology; Biologi; Naturvetenskap; Natural sciences;

    Sammanfattning : Transition from a vegetative growth phase to flowering in plants occurs in response to both environmental conditions and endogenous signals. Identification of genes that are involved in regulating the time of flowering is of great importance in agri- and horticulture. LÄS MER

  3. 2. Modifying xenogeneic immune recognition and engraftment by genetic engineering

    Författare :Zhong He; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Xenotransplantation; gene therapy; gene transfer; endothelium; promoters; monocytes; NK cells; alpha-Gal; lentivirus vectors; pancreatic islets;

    Sammanfattning : Transplantation using xenogenic organs, tissues and cells (i.e. xenotransplantation) is a potential solution to the shortage of those from human sources. Vascular endothelial cells (ECs) are the most immediate barrier between the xenogeneic donor organ and the host defense systems. LÄS MER

  4. 3. Molecular mechanisms for transcription in mammalian mitochondria

    Författare :Martina Gaspari; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :mitochondria; oxidative phosphorylation; mtDNA; transcription; TFAM; TFB1M TFB2M; POLRMT; promoter recognition; CSB II;

    Sammanfattning : The circular double stranded mitochondrial genome (mtDNA), which is about 16,600 bp in humans and 16,300 bp in mice, encodes 13 of the -90 different proteins present in the respiratory chain of mammalian mitochondria. The remaining components of the respiratory chain are encoded by nuclear genes and imported into the mitochondrial network. LÄS MER

  5. 4. Regulation of Adenoviral Gene Expression by the L4-33K and L4-22K Proteins

    Författare :Ellenor Backström; Göran Akusjärvi; Francoise Raffalli-Mathieu; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virology; Virologi; Medical Virology; Medicinsk virologi;

    Sammanfattning : The splicing pattern during an adenovirus infection is shifted at the late phase towards using weaker splice sites, splicing out larger introns. Splicing of weak 3´ splice sites usually requires recognition of the 3´AG dinucleotide before the first catalytic step of splicing. LÄS MER

  7. 5. Human insulin-like growth factor binding protein-4 and -6 : gene structure and transcription regulation

    Författare :Henric Zazzi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :IGF binding proteins IGFBP ; DNA sequencing; chromosomal localization; gene expression; Sp I; NF-kappa-B; methylation;

    Sammanfattning : Insulin-like growth factors (IGF-I and IGF-II) are among the more abundant growth factors isolated from bone tissue and are synthesized by various bone cells including osteoblasts. The activity of IGFs is controlled by a family of binding proteins (IGFBPs) divided into subfamilies depending on their individual affinity for IGFs. LÄS MER
