Position:PhD Student – Assay Development for the AHR Signature

in Dermatology

Department: DKTK partner site Essen / Düsseldorf - Klinik für Dermatologie

Code number: 2023-0055

The German Cancer Research Center is the largest biomedical research institution in Germany. With more than 3,000 employees, we operate an extensive scientific program in the field of cancer research.

Together with university partners at seven renowned partner sites, we have established the German Cancer Consortium (DKTK). At the partner site of DKTK Essen / Düsseldorf the German Cancer Research Center is offering a PhD position for assay development for AHR signature in dermatology.

The PredictAHR project utilizes existing data from the German Cancer Consortium of the tumor entities malignant melanoma, glioma, sarcoma, lung cancer and chronic lymphocytic leukemia and prospectively collects samples that are profiled using high-throughput methods. Our goal is to identify a reduced set of AHR activity markers that are specific to the different tumor entities and allow the development of simple assays for the clinic. Translating the transcriptional AHR signature to proteomics data will enable immunohistochemical evaluation by pathology laboratories, while extension to metabolomics data may enable translation to biological fluids such as blood and urine that can be obtained without surgical intervention. In summary, PredictAHR will investigate the predictive power of the AHR signature in various cancers and develop assays for AHR activity that can be integrated into the clinic.

Job description:

  • Cell culture: thaw, culture, split, freeze cells; functional in vitro analyses
