CDF - Career Development Fellowship
This Fellowship is awarded for a period of two years to early career clinician scientists undergoing medical specialist training with a strong interest in molecular medicine research topics. The fellows are integrated within the clinical setting of the Medical Faculty and aim at doing research at the interface of medicine and basic molecular biology and have the opportunity to work at a laboratory at the medical campus (e.g. OMZ) or at the EMBL. The fellows conduct their research in collaboration with a matching EMBL group.

Disease studied: Hematologic cancers, lympho- proliferative diseases (LPD)
Most cancer patients are treated with chemotherapy irrespective of diverse biology, but the discovery of key pathogenetic mutations has already transformed the treatment of specific cancer types. Successful examples of hematologic cancers include BCR-ABL inhibition of chronic myeloid leukaemia and as recently published by us, BRAF inhibition in hairy cell leukaemia.
We are aiming to understand the functional role of critical signalling pathways in lympho- proliferative diseases (LPD) and to determine the biological basis for differential response to genotype specific treatment. Pathway sensitivity and resistance of primary human tumour cells will be systematically mapped ex vivo using large and diverse compound libraries (up to 2500 compounds) across leukaemia s and lymphoma subtypes (refractory CLL, T-PLL, B-PLL, MCL, LPL, FL) to functionally group patients according to drug sensitivities. Paired with detailed molecular characterization of all tumour samples, and available clinical follow-up of the same patients, this novel and innovative approach provides unique opportunities to identify key pathways that determine sensitivity to specific drugs and drug combinations with the immediate potential for clinical translation.

Disease studied: T-cell acute lymphoblastic leukemia (T-ALL) in children
Leukemia is the most common malignancy in childhood. T-ALL accounts for approximately 15% of all ALL in children and adolescents. Whereas the primary T-ALL can be cured in more than 80% of patients with current treatment protocols, relapsed T-ALL is almost invariably fatal: during the time between first diagnosis and relapse, T-ALL evolves into a resistant disease by acquiring new mutations induced by chemotherapy and by selection of subclones. Using whole exome sequencing, Joachim hopes to find mechanisms of treatment resistance and understand the evolution of T-ALL during a patient’s course of disease.

EMBL host: Eileen Furlong, Genome Biology
Disease studied: Heart failure
Research focus: Heart failure is one of the main causes of death in the western world. Previously, histone deacetylase 4 (HDAC4) was identified as a cardioprotective factor. Understanding the molecular basis of its posttranslational modifications enabled the development of potential therapeutic tools for the treatment of heart diseases. For instance, the N-terminal part of HDAC4 inhibits specific transcription factors such as MEF2, which is one of the key regulators for pathological cardiac remodeling which leads ultimately to heart failure.
During the HRCMM project Lorenz aims to comprehensively identify MEF2 and HDAC4 regulated genes via ChIP-seq experiments. Subsequently, he will study their contribution to the transition from a healthy to a diseased heart. It is the overall goal to gain a deep understanding of the epigenetic modifications driven by HDAC4 and to identify epigenetic drug targets for cardioprotection.

Disease studied: Liver cancer
Research focus: Hepatocellular carcinoma (HCC) is one of the most frequent malignancies world-wide with an increasing incidence and a poor prognosis. Signalling cascades of (hepato-)carcinogenic pathways pass the nuclear envelope through the nuclear pore complex (NPC). The NPC is a multiprotein complex spanning the nuclear envelope and consists of ~30 nucleoporins (Nups). The project investigates compositional changes of the NPC occurring in the process of hepatocarcinogenesis and to what extent NPC remodelling modulates liver cancer-relevant pathways. In collaboration with the Beck lab (EMBL) Stephan will address this in vitro and in vivo by using targeted and non-targeted mass spectrometry, gene expression arrays, cell-based assays, murine HCC models, and human HCC samples. Tumour-specific alterations of the NPC may provide the basis for novel therapeutic approaches.
