POSTDOCTORAL BIOINFORMATICIAN
INTEGRATIVE, PATHWAY-BASED MODELS FOR RESPONSE PREDICTION IN COLORECTAL
CANCER
The development of novel anti-cancer agents that target growth signaling
pathways presents many challenges, the most demanding being to identify
which tumours are dependent on a given pathway and thus the patient group
most likely to respond to therapy. Current approaches rely on measuring
individual markers that act as surrogates for pathway status, but give
little information on activation state or cellular addiction.
This project will develop in silico techniques to integrate and analyse
genetics, genomics and protein level data with a focus on the PI3K and MAPK
signaling networks. A unique data set has been specifically assembled for
this project consisting of
- whole genome transcript data (Affymetrix HG_U133 Plus 2),
- whole genome high resolution copy number data (Agilent Human 244K),
- selected protein expression data using a reverse-phase array platform,
plus
- mutation status of genes frequently modified in colorectal cancer.
This comprehensive molecular characterisation has been completed on 58
colorectal cell lines and 64 primary colorectal tumors. In addition, the
pharmacological sensitivity of the colorectal cell lines to a range of
targeted drugs is know.
Specific objectives for this project include
- Model pathway status in colorectal tumours and cell lines through
integrative analysis of the molecular data
- Intersect tumour and cell line models to assess how accurately cell lines
recapitulate human disease at the pathway level
- Stratify colorectal tumours and cell lines on the basis of predicted
pathway activation
The results from this project will not only increase knowledge of colorectal
cancer and molecular stratification techniques, but provide valuable
information on the utility of cell line models for generating pre-clinical
hypotheses for personalised medicine.
CANDIDATE REQUIREMENTS
We seek an individual with knowledge of both informatics and biology, with
particular interest in translating complex data into testable hypotheses.
Candidates should fulfill the following criteria:
- PhD (or equivalent) in one of the following areas: bioinformatics,
engineering, computer science, statistics or physics.
- Knowledge of biology, particularly signaling pathways.
LOCATION
The position is primarily embedded within the Bioinformatics and Statistics
group led by Dr Lodewyk Wessels (http://bioinformatics.nki.nl) at the
Netherlands Cancer Institute, Amsterdam. The candidate will also spend time
in the AstraZeneca Oncology Informatics group, Alderley Park, UK led by Dr
Tim French.
