1. The MEN 1 Pancreas : Tumor Development and Haploinsufficiency
Sammanfattning : Multiple Endocrine Neoplasia Type I Syndrome (MEN 1) is a monogenic autosomal dominantly inherited cancer syndrome caused by a heterozygous loss of the MEN1 gene, predisposing for endocrine cell proliferation and tumor formation. MEN 1 carriers classically develop tumors in endocrine organs; the parathyroids, the endocrine pancreas, and the pituitary. LÄS MER
2. Cyclin A1 Expression and Regulation in Hematopoietic and Leukemic Cells
Sammanfattning : Increased expression of the cell cycle regulatory protein cyclin A1 has previously been detected in patients with acute myeloid leukemia (AML) and targeted overexpression of cyclin A1 in a transgenic mouse model initiated AML. The aim of this thesis was to further study the expression and regulation of cyclin A1 in hematopoietic cells. LÄS MER
3. Male Subfertility and Prostate Cancer Risk: Epidemiological and Genetic Studies
Sammanfattning : Androgen action plays a pivotal role in male reproductive tract physiology and pathology. The androgen receptor (AR) gene harbors two codon repeat tracts: the CAG and GGN repeats, encoding corresponding amino acid sequences of variable length; the polyglutamine and polyglycine stretches, respectively.

4. Studies of epigenetic deregulation in parathyroid tumors and small intestinal neuroendocrine tumors
Sammanfattning : Deregulation of the epigenome is associated with the initiation and progression of various types of human cancers. Here we investigated the level of 5-hydroxymethylcytosine (5hmC), expression and function of TET1 and TET2, and DNA methylation in parathyroid tumors and small intestinal neuroendocrine tumors (SI-NETs).

5. Statistics in Gene Expression, Metabolomics, and Comparative Genomics in Evolution
Sammanfattning : This thesis contains four papers concerning (I) the evolutionary conservation of drug targets and its potential use in environmental risk assessments, (II) RNA degradation as a control mechanism during osmotic stress in the yeast S. cerevisiae, (III) the localization and effects of the gene DDIT3 encoding a key regulator of stress response, and (IV) the integration and analysis of transcriptional and metabolic data to identify active metabolic pathways.
