Current Projects
IWT 040571 BIO-IT
Description:
BioScope-IT is FlandersBio's Bioinformatics Service Project to help
lower the threshold for Flemish biotech companies to apply
bioinformatics. BioScope-IT's main goal is to stimulate bioinformatics
awareness by building a solid network of excellence, and help biotech
companies to take the first step towards adoption of more advanced
computational solutions.
The project aims at dispersing bioinformatics information with
pro-active actions (meetings, workshops, seminars,...) on the one
hand, and to give site/company-specific technological advice on the
other. Biotech companies can direct their bioinformatics related
questions towards the BioScope-IT advisor-coordinators, who perform
the problem assessment and formulate ad hoc advice.
The project is funded by the framework of the Vlaamse Innovatie
Samenwerkingsverbanden (VIS) from the Institute for the Promotion of
Innovation by Science and Technology in Flanders (IWT).
FWO G.0229.03
| Title: |
Development of an ontology-based biological knowledge system for the acquisition of prior knowledge for use in bioinformatics algorithms |
| Period: |
01/01/2003-31/12/2006 |
| Cooperation: |
VUB - STARLab |
Description:
This project aims at the development of an ontology-based knowledge system containing biological information on yeast and prokaryotes with a main emphasis on Salmonellae. Such a knowledge system would allow biologists and bioinformaticians to efficiently retrieve biological information and, most importantly, to use this knowledge in the analysis of microarray data.
FWO G.0388.03
| Title: |
Ovarian cancer management using microarrays |
| Period: |
2003-2006 |
| Cooperation: |
Prof. I. Vergote and Prof. D. Timmerman, Department of Developmental Biology, Obstetrics and Gynaecology Section, K.U.Leuven |
Description:
We will use microarrays to measure expression levels of a given set of genes
in ovarian tumor cells (ovarian tumors taken from tissue collections). This
gives, for each experiment, an expression vector with thousands of
components (1 component for each probe or gene present on the array). The
determination of these expression levels can be repeated for ovarian tumor
cells coming from different classes or diagnostic categories.
We will use data mining techniques (existing and newly developed) to extract
medical and biological knowledge from the expression vectors. Basically,
this can be divided into three categories:
- Clinical predictions - Class prediction
- Looking for diagnostic categories - Class discovery by cluster analysis
- Gene or feature extraction

SQUAD: Salmonella's quorum sensing to attach disease
CAGE
Description:
The CAGE project aims to build a gene expression reference database. A
Consortium of European Arabidopsis functional genomics centers has teamed up
with bioinformatics partners that contribute expertise in microarray data
processing, analysis and storage/distribution. A total of 2000 Arabidopsis
samples will be produced and analysed under largely standardised conditions.
These samples will be profiled on CATMA microarrays containing gene specific
probes for most Arabidopsis genes, to build a Compendium of expression
profiles. The data will be assessed for statistical significance and submitted
to the ArrayExpress database at the European Bioinformatics Institute (EBI).
EBI will deliver specific CAGE ontology, and data submission pipelines. The
Compendium data will be annotated and analysed for content and confirmation of
gene function. The Compendium will further be maintained by EBI.
Past Projects
STWW-genprom
| Title: |
Deciphering upstream regulatory sequences from (plant) co-expressed genes |
| Period: |
2000-2003 |
| Partners: |
Prof. Pierre Rouzé, Bioinformatics, Plant Systems Biology, VIB, University Gent |
Description:
The goal of this project is to apply state-of-the-art pattern recognition techniques to build a prediction engine that finds promoters and regulatory elements in the genome of A. thaliana and other plants. Probabilistic sequence models are used to detect over-represented motifs in groups of co-expressed genes.
The regulatory elements that are known in plants based on literature and biolgical experiments, are stored in a specialised database PlantCARE.
Interdisciplinary Research Project (IDO)
| Title: |
Development of a generic mathematical methodology for inference of genetic networks |
| Period: |
2001-2004 |
| Partners: |
Prof. J. Vanderleyden, Center for microbial and plant genetics, Department of Applied Plant Sciences, K.U.Leuven
Prof. J. Thevelein, Laboratory of Molecular Cell Biology, Department of Biology, K.U.Leuven |
Description:
An interdisciplinary IDO project was set up to develop a generic method
applicable for inference of both prokaryotic and eukaryotic regulatory
networks based on gene expression data from microarray or RT-PCR
experiments using dynamical Bayesian networks.
FWO G.0115.01
| Title: |
Development of data-mining algorithms for microarray experiments in oncology |
| Period: |
2001-2004 |
| Cooperation: |
Prof. Koen Kas, Laboratory for molecular oncology, Center for Human Genetics, VIB, K.U.Leuven |
Description:
It is assumed that most cancers originate from genetic disorders. A more profound insight in these mechanisms will unmistakably be of major importance in making the right predictions and decisions. The goal of this project is to apply advanced datamining methods on microarray experiments for oncology.
The phenotype of the tumor is determined by the collection of disturbed gene expression levels. Microarrays allow us to measure the expression levels of thousands of genes simultaneously. These microarray experiments are repeated for different samples, under different conditions (e.g., tumor cells before and after metastasis, tumor cells originating from different tumor types, etc...). Comparing expression levels of genes/samples (by the use of data mining methods) allows us to perform:
- Class discovery (e.g., to determine the different tumor types or to group genes with similar behaviour)
- Class prediction (e.g., to predict diagnosis and staging)
- Feature selection (e.g. to select the relevant genes).
