1. Genetic Determinants of Obesity in Relation to Diet, Weight Gain and Mortality
Sammanfattning : Obesity is one of the major health concerns that has reached epidemic proportions globally. It is generally believed to be a result of interactions between genetic and environmental factors. LÄS MER
2. Array-based Genomic and Epigenomic Studies in Healthy Individuals and Endocrine Tumours
Sammanfattning : The human genome is a dynamic structure, recently recognized to present with significant large-scale structural variation. DNA-copy number changes represent one common type of such variation and is found both between individuals and within the somatic cells of the same individual, especially in disease states like cancer.

3. Functional and Molecular Characterization of BRCA1 and BRCA2 Associated Breast Cancer
Sammanfattning : This doctoral dissertation is based on five appended papers primarily concerned with three main topics, namely: the functional characterization of specific and clinically relevant perturbations found in BRCA1 ? one of the major breast cancer susceptibility genes; the use of microarray technologies for molecular characterization of hereditary breast tumor samples from a genomic perspective; and finally, the development of software to address some of the logistical problems of data analysis and management that arise when utilizing microarrays. Results obtained from the work presented herein demonstrate the following: that transcription az says can aid in the characterization of C-terminal missense mutations but that it may not be possible to unambiguously characterize variants with a yeast-based assay alone; that a naturally occurring C-terminal germline mutation in BRCA1 encodes a protein with apparent temperature-dependant functional properties; that open-source software can provide comprehensive solutions to meet data management needs of microarray experimenters; that BRCA1 and BRCA2 associated breast tumors exhibit markedly different copy number aberrations when compared to each other as well as to sporadic tumors; and that gene expression profiling in BRCA1 and BRCA2 associated breast tumors reveals specific gene expression patterns.

4. Post-zygotic Genetic Variation in Health and Disease
Sammanfattning : Post-zygotic genetic variation has previously been shown in healthy individuals and linked to various disorders. The definition of post-zygotic or somatic variation is the existence of genetically distinct populations of cells in a subject derived from a single zygote. LÄS MER
5. Multiple sclerosis : from genetic variants to biomarkers
Sammanfattning : Multiple sclerosis (MS) is a common chronic autoimmune and neurodegenerative disease of the central nervous system (CNS). MS is a debilitating disease that affects young adults, especially females. Why we develop MS? Is thought to be a consequence of our genes and the environment. LÄS MER
