16. Gene environment-interaction and cardiovascular phenotype in obesity and diabetes
Sammanfattning : Although a large body of evidence supports the notion that genes determine cardio-metabolic traits and outcomes, the non-genetic regulation of these events has recently gained increasing attention. Plastic chemical modifications of DNA-histone complexes defined epigenetic changes regulate gene expression by modifying chromatin accessibility to transcription factors. LÄS MER
17. 24s-Hydroxycholesterol : studies on regulatory mechanisms behind its formation in the brain and its potential use as a marker for neurodegeneration
Sammanfattning : Cholesterol 24-hydroxylase (CYP46A1) belongs to the cytochrome P450 super family and is responsible for conversion of cholesterol to the oxysterol 24S- hydroxycholesterol (24S-OHC). This structural modification allows 24S-OHC to traverse the blood brain barrier and this pathway is the major one for elimination of cholesterol from the mammalian brain. LÄS MER
18. Redox alterations in inflammatory diseases : diabetes, kidney failure and cancer
Sammanfattning : In order to combat oxidative stress and maintain the intracellular redox homeostasis, cells are equipped with antioxidant systems. The thioredoxin and glutaredoxin systems are the major thiol reducing systems and central antioxidant systems in mammalian cells. LÄS MER
19. Small molecules that affect the p53 pathway and their potential use in the treatment of cancer
Sammanfattning : The tumor suppressor p53 was identified 35 years ago and has since then been studied extensively, but despite all efforts, no drug or therapy directly involving it has been clinically approved - yet! A lot of potential new drugs are on their way that can reactivate p53 function by various mechanisms. Even a whole new approach called cyclotherapy has been established, during which p53 is activated in normal cells to protect patients from the adverse effects of chemotherapy while tumor cells are still being killed efficiently.

20. Roles of Myc and Mad in cell cycle and apoptosis
Sammanfattning : The Myc network proteins are key mediators in regulation of cell growth, differentiation and apoptosis. They are basic region hehx-loop-helix/leucine zipper (bHLH/Zip) transcription factors that require hetero-dimerization with Max for specific DNA binding Mad family members are expressed primarily in differentiated tissues where they recruit histone deacetylase complexes via the mSin3 interaction domain (SID) to repress transcription of target genes and prevent cell growth In contrast, members of the Myc family activate target gene transcription by recruitment of histone acetyltransferases to their transcriptional activation domain (TAD), inducing proliferation and S phase entry.
