Molecular Metabolism

We study how genes and lipids regulate diet induced metabolic diseases.

About the group

Nutrition, physical activity, genes and gender are environmental factors important for the development of metabolic diseases such as fatty liver, insulin resistance and obesity.

The molecular metabolism group study how genes and lipids regulate diet induced metabolic diseases. We also study the molecular mechanisms behind how physical activity can protect against the development of metabolic diseases.  Finally, we study why the genetic regulation of a variety of metabolic disease varies between the sexes.

An increasing number of people develop metabolic diseases. Eating an unhealthy diet, sedentary lifestyle, genetic variations, sex and age are all factors known to play important roles in the development of metabolic diseases. We want to develop new strategies to combat metabolic diseases. These strategies encompass both prevention and therapy. We are currently focusing on understanding how non-alcoholic fatty liver develop into fibrotic non-alcoholic steatohepatitis (NASH). We want to identify and molecularly clarify how specific genes and hepatic lipid species contribute to development of NASH. New knowledge about why and how some, but not all, people
