  STIM1 and ORAI1 regulate store-operated Ca2+ entry (SOCE) in most cell types, and mutations in these proteins have deleterious and diverse effects. We established a mouse line expressing the STIM1 R304 W gain-of-function mutation causing Stormorken syndrome to explore effects on organ and cell physiology. While STIM1 R304 W was lethal in the homozygous state, surviving mice presented with reduced growth, skeletal muscle degeneration, and reduced exercise endurance. Variable STIM1 expression levels between tissues directly impacted cellular SOCE capacity. In contrast to patients with Stormorken syndrome, STIM1 was downregulated in fibroblasts from Stim1R304W/R304W mice, which maintained SOCE despite constitutive protein activity. In studies using foetal liver chimeras, STIM1 protein was undetectable in homozygous megakaryocytes and platelets, resulting in impaired platelet activation and absent SOCE. These data indicate that downregulation of STIM1 R304 W effectively opposes the gain-of-function phenotype associated with this mutation, and highlight the importance of STIM1 in skeletal muscle development and integrity.

  In spite of amazing progress in food supply and nutritional science, and a striking increase in life expectancy of approximately 2.5 months per year in many countries during the previous 150 years, modern nutritional research has a great potential of still contributing to improved health for future generations, granted that the revolutions in molecular and systems technologies are applied to nutritional questions. Descriptive and mechanistic studies using state of the art epidemiology, food intake registration, genomics with single nucleotide polymorphisms (SNPs) and epigenomics, transcriptomics, proteomics, metabolomics, advanced biostatistics, imaging, calorimetry, cell biology, challenge tests (meals, exercise, etc.), and integration of all data by systems biology, will provide insight on a much higher level than today in a field we may name molecular nutrition research. To take advantage of all the new technologies scientists should develop international collaboration and gather data in large open access databases like the suggested Nutritional Phenotype database (dbNP). This collaboration will promote standardization of procedures (SOP), and provide a possibility to use collected data in future research projects. The ultimate goals of future nutritional research are to understand the detailed mechanisms of action for how nutrients/foods interact with the body and thereby enhance health and treat diet-related diseases.

  Obesity, type 2 diabetes (T2D) and its associated comorbidity atherosclerosis are the leading cause of mortality in the Western world. A major consequence of obesity is insulin resistance, which is strongly associated with deposition of fat and uncontrolled glucose production in the liver, thereby contributing to the development of T2D. Peroxisome proliferator-activated receptors (PPARs) and liver X receptors (LXRs) are lipid-activated nuclear receptors (NRs) that through target gene activation regulate systemic glucose and lipid metabolism, control cholesterol transport, and modulate inflammation within the vascular wall. The NR Group at the Department of Nutrition, UoO studies the LXRs and PPARs in cross-talk with signaling pathways activated by lipids, insulin and glucose. We have recently shown that LXRalpha and LXRbeta are targets for glucose-hexosamine-derived OGlcNAc modification in liver and macrophages. Importantly, induction of LXRa O-GlcNAcylation by high carbohydrate feeding coincides with increased expression of the lipogenic gene SREBP-1c. This intriguing observation gives insight into novel aspects of LXR activation, and suggests LXR to be an important mediator of sugar-induced hepatic fat deposition and insulin resistance. Our ultimate goal is to gain new understanding of the role of LXRs and PPARs in the development of diet-induced metabolic diseases and to identify and develop specific ligands from marine microalgae for the treatment of metabolic disease.
