Metastases, Metabolism and the Microenvironment

Metastatic disease and tumour immune evasion are two major hurdles in cancer therapy. Around 90% of cancer related deaths are indeed still caused by metastatic systemic disease. Tumour-draining lymph nodes (TDLNs) are immunological hubs and often the first site where metastatic tumour cells are detected. We are interested in the cells of the metastatic TDLN niche, the so called stroma, and how these influence metastatic spread and anti-tumour immune responses. A main goal is to characterize the cellular cross-talk between tumour cells, cells of the immune system and the LN stroma.

Metabolites can play a major role in these processes and although it is well known that tumour cell transformation is accompanied by alterations of cellular metabolism to facilitate growth and proliferation, little is known about how this transformation impacts the cells of the microenvironment and cellular cross-talk. Furthermore, each potential metastatic site with its distinct metabolic characteristics will pose different challenges for disseminating tumour cells adding another layer of complexity.

Within all our projects we use an interdisciplinary approach by combining complex in vitro models, mouse models and patient samples.

Angela studied Molecular Biotechnology at the University of Bielefeld and did her PhD in Molecular Oncology at the University of Southern Denmark. In 2013, Angela joined the lab of Jacqueline Shields at the MRC Cancer Unit at the University of Cambridge (UK) as a Postdoc. In 2017 she moved to another Postdoc position at the German Cancer Research Centre (DKFZ), where she joined Thordur Oskarsson’s group to further delve into metastatic niches in breast cancer. Since 2020, she is a Junior Group Leader at the MSNZ Würzburg.

Moutaz Helal


PhD Student


Tel.: +49 931 31-#####

Moutaz obtained his bachelor’s degree in pharmacy in Egypt where he developed a deep interest in cancer research. Thus, he decided to pursue his master’s in the field of molecular oncology within the biochemistry program of the University of Würzburg.

He joined the MSNZ as a Master’s student and started his PhD project in October 2021. The project is focused on investigating stroma-mediated chemoresistance mechanisms in breast cancer and multiple myeloma utilizing state-of-the-art single-cell high-throughput sequencing techniques.
