Molecular Pathogenesis of Hematological Neoplasias

collaboration between the Institute of Pathology, the CCC-Mainfranken, the Department of Internal Medicine II, the Clinical Research Unit 216 (CRU 216), the “Sander-Therapieeinheit Multiples Myelom”, the “Deutsche Studiengruppe Multiples Myelom” (DSMM) and the International Cancer Genome Consortium (ICGC)

Our group is interested in the molecular pathogenesis of multiple myeloma (MM) and malignant B-cell lymphoma. Specifically, the group focuses on the clinical and molecular characterization of newly detected somatic mutations in MM and the clinical and molecular characterization of t(14;18)-negative follicular lymphoma (FL). Next generation sequencing (NGS) approaches in primary MM and FL patients such as whole exome sequencing and amplicon-sequencing for the detection of single nucleotide variants as well as the integration of gene expression and copy number data are underlying techniques to define and analyze certain molecular subgroups and to identify potential oncogenes that may serve as targets for a more personalized therapeutic approach. Subsequently, in vitro human cell line models are used to better understand the underlying biological processes that are caused by single oncogenic mutations.
