Broer Group - Membrane transport and nutrition
Nutrients are essential for the growth and maintenance of cells and organisms. Membrane transporters are essential to deliver nutrients to cells and tissues and thus play a significant role in the regulation of metabolism. We study the role of amino acid transport in the onset of insulin resistance and the regulation of carbohydrate metabolism. Amino acid transport is crucial for growing cells and thus is a target to curtail cancer growth. We are investigating in how far amino acid transport in cancer cells is different from normal cells. In addition to amino acid transport we investigate the role of phospholipid transport in cell development and signalling in the immune system.
