Sammanfattning : Genome-wide association studies (GWAS) have identified thousands of loci associated with cardiac and cardiometabolic traits. However, the trait-associated variants usually do not clearly point to causal gene(s), mechanism(s) or tissue(s). Model systems that allow for a comprehensive and quick candidate gene screening are necessary, ideally in vivo. LÄS MER
2. The role of leptin in zebrafish (Danio rerio) : Novel insights into appetite regulation and reproduction
Sammanfattning : The hormone leptin is a peripheral metabolic signal and an important regulator of energy balance. In mammals, leptin acts on the appetite centers in the hypothalamus, causing anorexigenic functions by inhibiting food intake. It is also considered as a link between the nutritional status and the endocrine reproductive axis. LÄS MER
Sammanfattning : The vertebrate skeleton is composed of bony and cartilaginous structures that are developed under the control of numerous genetic networks. The transcription factor Nkx3. LÄS MER
4. Zebrafish models for large-scale genetic screens in dyslipidemia and atherosclerosis : Validation and application
Sammanfattning : Hundreds of loci have been robustly associated with circulating lipids, atherosclerosis and coronary artery disease; but for most loci the causal genes and mechanisms remain uncharacterized. The overall aim of my thesis is to develop and validate novel in vivo model systems that are suitable for high-throughput, image-based genetic screens in coronary artery disease and related traits, and use these model systems to systematically characterize positional candidate genes.

Sammanfattning : The G-protein coupled receptors (GPCRs) comprise the largest family of receptors in humans and other vertebrates. They are embedded in the cell membrane and are activated by many different signaling molecules. Activation modulates cellular signal transduction pathways and influences many physiological processes.
