9. Disease progression in rheumatoid arthritis
RNA-seq + BS-seq
Part of the BTCURE research project, in collaboration with the Academisch Medisch Centrum
(Amsterdam, NL).
Pilot study involving a small number of synovial biopsies from RA patients at different stages and
degrees of severity profiled by RNA-seq and BS-seq.
Objective: identify gene expression and methylation signatures that could highlight disease
progression mechanisms.

23. Conclusions
Leveraging functional genomics analytics for target discovery
Making drugs is a very failure-prone business. To increase our chances of success, we need to have
better understanding of the biology of:
– Our diseases;
– Our targets;
– Our drugs.
High-throughput sequencing assays and functional genomic data are more and more widely used
in GSK to drive and support these activities.
This type of data poses two main challenges:
– Data plumbing: create an infrastructure that is able to deal with the size of these datasets, in terms of both
storage and processing power.
– Data analytics: develop appropriate analytical pipelines that allow to integrate, visualise, analyse and
interpret the data.
Partnerships with CTTV and Altius demonstrate our vision of a pre-competitive, collaborative space
for target identification and validation.
