Dioscuri Centre for Metabolic Diseases

Dioscuri (Dioscuri Centres of Scientific Excellence) is a programme initiated by the Max Planck Society, jointly managed with the National Science Centre in Poland, and mutually funded by the Polish Ministry of Education and Science (MEiN) and the German Federal Ministry of Education and Research (BMBF)

Our Dioscuri Centre for Metabolic Diseases focuses on the elucidation of signaling pathways that play a role in metabolic diseases like type 2 diabetes or cancer associated cachexia.

Mission of the lab

In our laboratory, we focus on understanding the signaling networks governing nutrient absorption, deposition, and utilization in different cell types.

Perturbations in signaling cascades evoked by nutrient overload, environmental stress, or aging contribute to the dysfunction of multiple organs. This results in a metabolic imbalance in adipose tissue, intestine, skeletal muscles, and liver that can lead to the development of obesity, type 2 diabetes (TD2), non-alcoholic fatty liver disease (NAFLD), or skeletal muscle loss (sarcopenia). We aim to understand complex signaling networks which regulate nutrient absorption, deposition, and utilization in the abovementioned organs. Especially, we focus on the crosstalk between kinase and ubiquitination-dependent signaling cascades. For this purpose, we combine cell biology, biochemical, and omics approaches with mouse genetics. Using high throughput screening we identified a number of novel kinases regulating lipolysis, including ERK3. Moreover, targeted mouse genetics approach allowed us to establish members of the Protein kinase D family as central regulators of adipocytes’, enterocytes’, and hepatocytes’ metabolism. We plan to further investigate the identified pathways putting special emphasis on their impact on the development of metabolic diseases. In parallel, we utilize screening approaches to find other, non-canonical signaling modules (components of the ubiquitin system) regulating metabolism. Finally, our laboratory is implicated in multiple collaborative projects with Polish and international research institutions and companies. One of them resulted recently in the identification of the role of platelets-derived lipids in the regulation of insulin secretion and the development of age-dependent diabetes. We also actively collaborate with industrial partners to develop drugs targeting identified by us pathways. Therefore, by determining essential signaling networks regulating basic metabolic processes our projects will contribute to more targeted pharmacological strategies for the treatment of metabolic diseases such as obesity, T2D, NAFLD, or sarcopenia.
