Integrating whole genome sequencing (WGS), transcriptomics, proteomics, and patient phenotypic data to identify predictive biomakers for rheumatoid arthritis biologic treatments

Subject: Biomedical Sciences


Summary

Rheumatoid arthritis (RA) is a chronic destructive disease of joints, which affects ~ 25 million adults in the world. As a painful and disabling disease RA presents significant healthcare burden to society. The standard treatment route of RA starts with traditional DMARDs (Disease-modifying anti-rheumatic drugs), such as Methotrexate, to which 30-40% of patients would not respond. Those non-responders will undergo anti-TNFa based biologic treatments, but again 30-40% of them would not respond to TNFa biologics and they are referred to as secondary non-responders. While we conduct related research to identify potential drugs for the secondary non-responders, it would be highly desirable to be able to accurately predict using effective biomarkers which patients are secondary non-responder, in order to triage high cost of biologic drugs.

In this project, we are exploiting gene expression data from public databases,  WGS and proteomics data from our own patient cohort, together with patient demographic and clinical phenotypic data, to develop integrative bioinformatics analysis pipelines with  the aim is to identify high quality genomic biomarkers of secondary non-responder among RA patients.

The overall aim of the project  will be achieved through the following steps:

1)We have identify a number of suitable datasets containing the gene expression profiles of secondary non-responders and responders; differential expression analysis on the transcript level will allows us to identify genes that are strongly associated with biologic drug response.

2)We have conducted proteomics analysis using olink technologies to profile our patient cohort with selected panels of proteins related to immune response, inflammation etc. Bioinformatics analyses of the proteomics data and patients’ secondary response status data will identify candidate proteins that are strongly associated with biologics response.

3)All the patients in our cohort will have their whole genome sequenced as a research collaboration with Genomics Medicine Ireland. This provides a rich source of information on the full genetic makeup of all our patients. We will develop and test robust bioinformatics pipelines for the processing and analysis of WGS data.

4)Integrating the three streams of data as described above and patients drug response data, we will develop and test an integrative bioinformatics approach to identifying highly promising genomic biomarkers that are predictive of RA patients’ response to biologic treatments. The integration of all three types of omics data is essential as it helps to narrow down the search space of WGS, increase confidence, and converge to the most effective genomics biomarkers for biologic drug response.

5)We will perform validations on the predictive biomarkers with an independent public dataset and/or new cohort of RA patients.

This is primarily a Bioinformatics and BigData research project, with data obtained from both public domain and our own centre; it requires an individual with good computational skills and statistical knowledge.  A good understanding of basic biological processes and some experience with basic biological lab experiments would be desirable, but training on these aspects will be provided during the course of PhD study.
