Within a DFG funded project, the research group of Prof. Dr. Franziska Jundt at the Comprehensive Cancer Center Mainfranken in Würzburg invites applications for a Postdoctoral position in Cancer Research (m/f/d) to conduct research on the project commencing on 01.03.2025. The position is initially limited to 3 years. We offer a full-time position (100%).
Bone lesions, bone fractures, and impaired bone remodeling occur in myeloma bone disease (MBD), a debilitating skeletal condition developing in patients suffering from the plasma cell disorder multiple myeloma (MM). In MBD, bone marrow-derived mesenchymal stromal cells (MSC) display a shift towards adipogenic differentiation, while osteogenic differentiation is impaired. With its increased bone marrow adipose tissue (BMAT), obesity is a risk factor for MM, as increased adipogenic differentiation may support tumor growth and dampen osteogenesis. Mechanical loading of bone induces mechanotransduction in MSC and osteoblasts, being a stimulus for osteogenic differentiation and bone growth. In a mouse model for MBD, we have shown that mechanical loading of a MM-bearing hindlimb is a countermeasure for tumor growth and induces bone regeneration. In this new project, we will investigate whether mice with MM and high BMAT similarly benefit from mechanical loading (2g hypergravity) and whether mechanical unloading, leading to an osteoporotic bone phenotype, is an additional risk factor in this context. We will characterize bone microarchitecture, analyze tumor growth and size, measure serum parameters, validate our results in 2D and 3D cell culture models, and correlate our findings to patient data. The following hypotheses will be addressed: in obese mice suffering from MBD, mechanical loading (a) restores the bone phenotype, (b) reduces MM tumor burden, and (c) has an altered transcriptional and epigenetic signature in bone cells. This binational project combines the complementary expertise of three French PIs (bone, mouse loading and unloading models, metabolism, epigenetics) and two German PIs (MBD/MM, mechanical loading, bone cell biology, mechanotransduction). Overall, our results will contribute to the understanding of MBD progression in compromised bone and bone marrow and the impact of mechanical up- versus un-loading in metabolically challenged conditions.
The three-year full-time postdoctoral researcher position (100% TV-L E13) will be funded through the German Research Foundation (DFG).
In the case of a university degree from a non-EU country, a long version of the certificate evaluation from the Central Office for Foreign Education is required.
Remuneration is in accordance with the relevant collective agreements. Severely disabled applicants will be given preference if they are otherwise equally qualified.
