The liver develops during embryogenesis and continues to grow after birth until it reaches an appropriate size that ensures adequate functional liver capacity in relation to body size. Moreover, the liver has the unique capability to regenerate after injury, e.g. after partial hepatectomy. This regenerative capacity is crucial for preserving its size and, subsequently, maintaining body homeostasis. However, chronic liver damage, which results in persistent loss of hepatocytes, can lead to detrimental outcomes. For example, the emerging metabolic dysfunction-associated steatotic liver disease (MASLD) can progress to end-stage liver disease, and hepatocellular carcinoma (HCC).
Numerous studies have established that the pathways coordinating postnatal liver development are also involved in liver regeneration and cancer development. However, the precise mechanisms coordinating these different biological processes and how they are linked remain incompletely understood. This project aims to provide new insights into the molecular mechanisms that govern postnatal liver growth and to elucidate their potential contributions to liver regeneration and HCC.
Specifically, in this project, we will use state-of-the-art molecular and biochemical tools, such as CRISPR technology, combined with innovative mouse models, to elucidate basic principles by which a key protein complex within the endosomal network governs postnatal liver maturation, liver regeneration, and liver cancer. In addition, we will elucidate how cholesterol metabolism contributes to these different processes.
This position offers a unique opportunity to work at the forefront of liver biology research and cholesterol metabolism, with access to cutting-edge tools and a collaborative research environment
