PhD student position (m/f/d) (Biology, Biochemistry, Life Science)

The Department of Hematology, Oncology, Hemostaseology and Stem Cell Transplantation offers a

PhD student position (m/f/d) (Biology, Biochemistry, Life Science)available from the next possible date for 3 years ( TV-L EG13, 65%). The position is part of the clinical research unit (CRU344) “Untangling and Targeting Mechanisms of Myelofibrosis in Myeloproliferative Neoplasms” which is funded by the German Research Foundation (DFG).

Activities and responsibilities

Myeloproliferative neoplasms (MPN) are accompanied by inflammation that arise in part through stimulation of cytokine production by the malignant clone, but which is also reinforced by cytokines secreted from the bone marrow microenvironment. MPN mesenchymal stromal cells (MSCs) of the microenvironment and their progeny often transform into cell types that support fibrotic processes. Current therapeutic strategies in chronic myeloid leukemia (CML) may reduce cytokine secretion by the malignant hematopoietic cell clone but likely fail to target the microenvironment. As a consequence, this malignant environment can further fuel altered signaling in the malignant clone besides therapy. Which factors are specifically secreted by the bone marrow niche, the cell types secreting these factors, and how this could be targeted to prevent persisting signaling in the malignant clone is not fully understood. Our recent work has revealed the role of JAK1-STAT3 signaling in the malignant clone for the persistence of malignant stem cells. Interestingly, this signaling axis is driven by the malignant microenvironment (Kuepper et al., Leukemia 2019, PMID 30842608). In the current project, the candidate will therefore explore the impact of specific microenvironmental-derived factors on the survival of malignant stem cells and will investigate the effect of cytokine inhibition in vivo, with respect to the malignant clone and the tumor niche. During this project, the candidate will utilize techniques from multiple fields such as biochemistry, molecular biology, mouse genetics and state of the art imaging.
