Project description:

Tumor suppressive mechanisms in liver cance
The groups of Dr. Stephanie Rössler and Dr. Kai Breuhahn at the Institute of Pathology at Heidelberg University Hospital are seeking a highly motivated PhD student. Our laboratory is interested in the role of genetic alterations in hepatocellular carcinoma (HCC). Liver cancer is the second leading cause of cancer-related death worldwide. The high mortality rate of HCC is mainly caused by metastasis or by de novo tumor formation in the diseased liver.
The project of the successful candidate will focus on the functional characterization of tumor suppressor genes on chromosome 8p in HCC. We employ a broad range of techniques, including mouse models, molecular biology and biochemistry (protein-protein interactions), cell biology (live-cell imaging) and computational analysis to connect molecular biology and medical relevance.
We offer a friendly and productive interdisciplinary work atmosphere and state-of-the-art equipment within the newly established and DFG funded SFB “Liver cancer”. The PhD student will be part of the local PhD Program, which offers interdisciplinary practical training, scientific conferences, mentoring by a thesis committee of experts in the field, and a highly stimulating international research environment.
