The common theme of the Translational Onco-genomics and Bio-informatics lab (UGent) headed by Katleen De Preter is the development of analytical and bio-informatic pipelines for diagnostic, prognostic and predictive analysis enabling a more precise cancer management.
Previous research projects have led to new prognostic and predictive biomarkers for neuroblastoma which opened new perspectives on clinical management of these patients. This work was driven by the application of various bioinformatics tools exploring transcriptomic data from primary neuroblastoma samples. This resulted in the identification and dissection of oncogenic pathways (including ALK and FOXM1 pathway) to pinpoint new vulnerable nodes for therapy (ref 1 and 2) and the establishment of m(i)RNA expression signatures for a more accurate prognosis. At the genomics level, we succeeded in the identification of prognostic DNA copy number alterations for high-risk neuroblastoma by an extensive international collaborative study (ref 3).
The past years our research focus has shifted from neuroblastoma to a broad spectrum of cancer entities, including lung cancer, esophageal cancer, prostate cancer, various pediatric cancers as well as CUPs (cancers of unknown primary). Moreover, we embarked on the processing of liquid biopsies such as blood plasma for the analysis and interpretation of genomic biomarkers. In this context, we also focus on the development of dedicated data mining pipelines that should accompany these new analytical tools and which are necessary to fully exploit the clinical application for the cancer patient. For instance, we established a new analytical and bioinformatics pipeline to identify the copy number profile for prognosis based on cfDNA (circulating cell-free DNA) isolated from blood plasma (ref 4). In addition, we developed a method that measures the DNA methylation profile of cfDNA and that aids in diagnosis of both pediatric and adult cancers (ref 5 and 6). At the moment, we are investigating the potential of circulating RNA and DNA from blood cells as marker for drugs sensitivity including immunotherapy. To allow the interpretation of bulk omics data of complex mixtures (such as in blood), we have built ample expertise in computational deconvolution of bulk omics data which is an emerging new area in bioinformatics. This computational method allows to dissolve data from a complex mixture in its individual components and is also highly relevant in the context of tumor heterogeneity (ref 7 and 8). Since recently, we embarked on the analysis of tumor heterogeneity using also single-cell omics tools.
In summary, our team has expertise in (single-cell) genomics, bioinformatics and (liquid biopsy) biomarker research for pediatric and adult cancers. Importantly, our research is positioned at the interface between technological/bioinformatic development and clinical validation/implementation.
In 2000, Katleen De Preter obtained a Master in Bioscience Engineering (Cell and Gene Biotechnology) at Ghent University. During her PhD and post-doctoral fellowship in the team of prof. Frank Speleman, she was involved in genomics profiling of neuroblastoma tumors aiming to identify new vulnerable markers for therapy and better biomarkers for prognosis and prediction. Since 2011, Katleen became part-time professor at Ghent University and started the research lab of Translational Onco-genomics and Bio-informatics.
In 2019, she obtained a position as full professor with a BOF-ZAP grant. She is author of more than 100 scientific articles in international journals and has a H-index of 42 (Web of Science, May 2020).
In May 2019, her work on biomarkers for neuroblastoma was rewarded with the Antoine Faes price. Katleen was one of the CRIG co-founders and since end 2019 she is member of the CRIG steering committee.
In 2022, Katleen obtained an ERC consolidator grant for the “EpiGuide” project. End of 2022, she joined the Center for Medical Biotechnology at VIB-UGent as group leader.
