  • The overall aim of Dr. Jaeschke's laboratory is to investigate the role of stress-activated protein kinases in metabolic signal transduction. Metabolic syndrome, which is associated with obesity, insulin resistance, type 2 diabetes, and non-alcoholic fatty liver disease (NAFLD), is a major health problem world-wide.

    The cJun-NH2-stress-activated kinase (JNK) pathway is emerging as important player in the development of obesity-induced insulin resistance and NAFLD.

    The major goal is to obtain deeper knowledge of the mechanism by which obesity regulates the JNK pathway and how this pathway is involved in the control of metabolic diseases. This information will provide the basis for the design of rational therapeutic strategies for the control of metabolic diseases.

    The methods that the lab is using include recombinant DNA technology, general biochemical techniques, cell culture and knock-out mice.
