  2. 16. Mechanisms and regulations of priming effects in soil

    Author : Jian Li; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Soil organic matter (SOM) plays a significant role in the global carbon (C) and nutrients cycles, not only since SOM is a major storage reservoir of C and plant nutrients, but also since microbial decomposition of SOM releases large quantities of CO2 to the atmosphere. The accelerated or reduced turnover rate of SOM after the input of labile C compounds is a phenomenon known as the priming effect (PE). READ MORE

  4. 17. Cellular pathways and molecular regulation of hematopoietic stem cells

    Author : Kristina Anderson; Stamcellscentrum (SCC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; β-catenin.; lineage commitment; hematopoietic stem cells; lineage priming; Wnt signaling pathway; biphenotypic cells; PAX5;

    Abstract : Hematopoietic stem cells (HSCs) are defined by their unique properties to self-renew and differentiate into all hematopoietic cell lineages. Residing in the bone marrow (BM), adult HSCs are organized in a hierarchy of cells that differ in their self-renewal and proliferative capacity. READ MORE

  5. 18. Replication Fork Stability in Mammalian Cells

    Author : Ingegerd Elvers; Thomas Helleday; Jan H. J. Hoeijmakers; Stockholms universitet; []
    Keywords : replication fork progression; replication fork stability; re-priming; DNA damage signalling; NATURAL SCIENCES; NATURVETENSKAP; molekylärgenetik; Molecular Genetics;

    Abstract : Maintaining replication fork integrity is vital to preserve genomic stability and avoid cancer. Physical DNA damage and altered nucleotide or protein pools represent replication obstacles, generating replicative stress. Numerous cellular responses have evolved to ensure faithful DNA replication despite such challenges. READ MORE

  6. 19. Fungal and bacterial contributions to decomposition in terrestrial and aquatic ecosystems

    Author : Margarida Soares; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fungi; bacteria; microbial carbon use efficiency; litter decomposition; priming effect; heavy metal stress;

    Abstract : Microbial decomposers process a great majority of net primary production in the biosphere and regulate carbon (C) and nutrient cycling. Microbial communities are extremely diverse and often disregarded from global C-cycling models, but one strategy to overcome this challenge is to focus on the major decomposer groups: fungi and bacteria.

  7. 20. Tools for understanding the glycosaminoglycan biosynthesis

    Author : Daniel Willén; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Xylosides; Glycosaminoglycans; Proteoglycans; β4GalT7; Carbohydrate synthesis; GAG priming; GAG inhibition;

    Abstract : For cells to function correctly within an organism, they need different systems to communicate with each other. One crucial part of cell signaling is the proteoglycans (PGs) and glycosaminoglycans (GAGs), which are macromolecules that bind different signaling molecules and proteins necessary for processes such as growth and proliferation.
