  1. 16. The role of polysaccharide modifications during Drosophila development

    Författare :Florian Lüders; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ontogeni; growth animal ; embryologi; Development biology; Decapentaplegic; Hedgehog; Wingless; Sulfation; Pipe; Glycosaminoglycan; Glycosyltransferase; ontogeny; embryology; Utvecklingsbiologi;

    Sammanfattning : Glucosides attached to proteins and lipids have been shown to modulate the activity of signal transduction pathways regulating growth and patterning processes during animal development. In particular, O-linked glycans such as glycosaminoglycans (GAGs) have been implicated in modulation of growth factor signaling pathways. LÄS MER

  3. 17. The function of Smc5/6 in Drosophila development and at the heterochromatin-like locus HMR in budding yeast

    Författare :Martin Tran; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The structural maintenance of chromosome 5/6 (Smc5/6) complex is one out of many factors in the cell that maintain genome stability. Smc5/6 has been implicated in processes such as DNA double-strand break (DSB) repair, replication progression, and chromosome segregation. LÄS MER

    Sammanfattning : Neuroblastoma is a tumor of the sympathetic nervous system, and arises during early childhood. The tumor is highly heterogeneous and evidence, such as expression of genes normally only expressed during embryonic and fetal stages, suggests that the tumor is of embryonic origin and that the tumor arises as a consequence of perturbed differentiation during the development of the sympathetic nervous system.

  5. 19. Gene expression in carcinogenesis

    Författare :Heléne Fischer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : It is important to understand the processes of carcinogenesis and to find out which genes are involved . One way to study the process on a molecular basis is to identify differences in gene expression. LÄS MER
