Forskning

The research interests of the microRNA and diabetes biology Group focuses (not surprisingly) on diabetes mellitus and the insulin secreting β-cell, which is located in the Islets of Langerhans in the pancreas. We are particularly interested in the role of the non-coding RNA species called microRNAs.

The lab has several projects that focus on the molecular events leading to β-cell failure during development of Type 2 diabetes mellitus. We are also generally interested in mechanisms in cell or molecular biology involved in development of diabetes mellitus and its complications. We are also investigating how microRNAs in the blood stream may be used as biomarkers to gain knowledge on risk of diabetic complications or progression to diabetes development; for example during development of pregnancy-induced diabetes.

MicroRNAs are tiny 21-23bp single-stranded RNAs that the cell endogenously express. The microRNA is transcribed as a longer precursor with a stem loop structure. Subsequently the miRNA is excised from the stem loop and transported out of the nucleus where it enters the same RISC complex as exogenously added small interfering RNA do. The microRNA then act as a transcriptional or translational repressor by binding to mRNA targets. Complete base pairing between the microRNA and the target mRNA will direct target mRNA degradation, while incomplete base pairing will halt translation of the mRNA. Thus, due to the small size and the possibility of incomplete base pairing a single microRNA may have multiple target mRNAs. MicroRNA thus acts as an extra layer of gene-regulation on top of the normal gene-regulation by transcription factors and cellular signalling.  The lab is interested in the role of miRNAs in β-cell development and β-cell function. We are also involved in projects looking at microRNAs as biomarkers for development of diabetes-related traits.

The role of oxidative stress and anti-oxidative proteins following exposure of β-cells to increased glucose and fatty acid levels is a field of long-time interest. The putative anti-oxidative protein Uncoupling protein 2 is induced by glucose and fatty acids, but this induction causes defective insulin secretion. However, the induction of UCP2, while causing β-cell dysfunction, presumably protects against apoptosis due to oxidative stress. 

The lab uses general molecular biology and cell biology tools to study the questions at hand. These include Q-PCR, cloning (expression, RNAi), northern blotting, western blotting, promoter studies, transfektion of cells. In general we use either isolated islets of Langerhans or a transformed β-cell line (insulinoma cells) for our experiments. Our research typically involves measuring insulin secretion, insulin content, cell survival or apoptosis, ATP content and various other metabolic assays. In order to investigate how molecular and cellular events depend on specific microRNAs we generate genetically modified cell lines either specifically over-expressing the microRNA or selectively deplete its levels.

Research focus

  • Endocrinology and  metabolism  
  • Genetics/genomics of endocrinology, diabetes and obesity
  • Development of novel biomarkers for patient stratification and improved prognosis of patients with focus on, but not limited to, the metabolic reproductive syndrome (PCOS) and diabetic foot ulceration
  • How the metabolic syndrome causes pancreatic beta cell dysfunction
  • How microRNAs regulate cellular metabolism and mitochondrial function, and the function of pancreatic β-cells

 

 

Current projects

  • MicroRNA biomarkers in general; MicroRNA profiling in patients with the reproductive metabolic syndrome (PCOS) – evaluations of microRNAs as potential biomarkers from follicular fluid obtained at IVF or from base-line serum.
  • MicroRNAs associating with childhood obesity and associated risk factors, such as hepatic steatosis and cardiovascular risk factors.
  • MicroRNAs in chronic diabetic complications, such as the impaired wound healing of long-standing diabetes mellitus. In this cross disciplinary project we have profiled microRNAs altered in diabetes during wound healing in a mouse model and have tested microRNA inhibitors together with antibacterial peptides for their effect to improve wound healing in vivo. In a related project my group relates microRNA levels in diabetic foot ulcer swaps with healing progression.
  • MicroRNA in mitochondria as molecular targets in metabolism. We have discovered that certain microRNAs are depleted or enriched in the cellular organelle, the mitochondria. This project has the aim to map microRNAs changed in mitochondria from liver or skeletal muscle in diabetic or obese rodent models, and to characterize their modes of action and transport.
  • MicroRNAs in pancreatic islets and their role in glucose toxicity or islet cell proliferation. We have discovered that microRNA-29 family members are upregulated by chronically elevated glucose (glucose toxicity) and are currently investigating the molecular mechanisms by which miR-29a decreases beta cell function.
