Integrative Analysis & Developmental Cancer Genomics
Dr. Florian Halbritter (PhD)
Our goal is to understand how dysregulated development of progenitor cells results in childhood cancers.
Cancer and development
Cancer is a disastrous growth of cells in the body. In the most common types of cancer, this growth is brought on by a series of many mutations – accumulated throughout life and possibly influence by extrinsic factors. Childhood cancers are different. In young age, cells have not usually attained many mutations yet, but rather there are individual catastrophic events that occur in undifferentiated cells during the orderly growth of the organism. These singular mutations throw developing cells of their designated path and result in malignancies. However, for most pediatric cancers, the exact histogenesis is not fully understood. Insight into how mutations affect development will ultimately elucidate new avenues for detecting (diagnosis), projecting (prognosis), and interfering (therapy) with aberrant development in childhood cancers.
Our research: Taking apart pediatric cancer bit by bit
We are a team of computational biologists approaching childhood cancer development with a scientist’s curiosity in three facets:
- Developmental biology: We chart cellular plasticity in tumors and trace it back to normal development in time and space.
- Regulatory epigenomics: We map the regulatory networks that shape cell identity and identify they role of key regulators.
- Integrative analysis: We develop and apply computational tools that connect pieces of data into knowledge.
Our research combines analysis of clinical samples as well as in vitro and in vivo models with computational, statistical, and machine learning methods to dissect the molecular framework of pediatric cancers. To this end, we apply and develop high-throughput functional genomics technologies (single-cell RNA-seq, ATAC-seq, ChIP-seq, RRBS/WGBS, lineage tracing) and often work in close collaboration with experimental and clinical scientists in the institute and worldwide.
There are three aspects of development that are currently at the heart of our interest: Intra-tumor plasticity, the influence of non-tumor cells on plasticity, and the impact of chromatin state on the receptiveness of cells for developmental changes. We study these using primarily pediatric sarcomas, blastomas, and leukemia as model systems.
