3. 2. Hypoxic gene regulation and oncogenic pathways in neuroblastoma

   Författare :Erik Fredlund; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microarray; hypoxia; MYCN; gene expression analysis; Neuroblastoma; Myc; pathway analysis; differentiation;

   Sammanfattning : Neuroblastoma patients show remarkable clinical heterogeneity, with courses ranging from spontaneous regression to fatal tumor progression despite intense multi-modal treatment. Previous studies have shown that hypoxia pushes neuroblastoma cells towards a more immature phenotype, which correlates to aggressive disease. LÄS MER

4. 3. 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

5. 4. Novel endogenous mechanisms of complement regulation - A delicate balance

   Författare :Andreas Holmér; Malmö Klinisk kemi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; short leucine rich glycoprotein; factor H; C1q; age-related macular degeneration; C4b-binding protein; prion disease; prion protein; Complement regulation; C-reactive protein;

   Sammanfattning : In this thesis, the biochemical mechanisms for complement activation by endogenous proteins are explored. The short leucine-rich repeat proteins (SLRPs) help organise extracellular matrices. We found that several SLRPs bind C1q and of these, fibromodulin and osteoadherin trigger complement. LÄS MER

7. 5. Bioinformatics studies on the mechanisms of gene regulation in vertebrates

   Författare :Awaisa Ghazal; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Gene regulation implicates an important role in organismal complexity through contributing to phenotypic variation. In my thesis, I studied three diverse components of gene regulatory networks including transcription factors, DNA methylation and microRNAs to elucidate their role in vertebrates. LÄS MER
