PhD Studentship in Epigenetics - Using chromatin interaction analysis and CRISPR-Cas9 mediated genomic editing to identify the target genes of osteoarthritis-associated transcriptional regulatory elements
Number of awards:
Start date and duration:
September 2018 for 3 years.
Osteoarthritis (OA) is a chronic musculoskeletal disease that affects the synovial joints, including hips and knee. OA is the leading cause of chronic disability in the UK, affecting 8.5 million people. There are currently no disease modifying drugs available, and in order to aid diagnosis and identify new therapeutic targets, increased understanding of the molecular mechanisms underlying the disease process is required.
Changes in epigenetic mechanisms of regulating gene expression, including altered DNA methylation, have been identified as a significant contributing factor to the pathogenesis of OA. DNA methylation levels in enhancer regulatory elements are known to reflect their activity. Previous genome-wide analysis comparing healthy and OA tissue has identified that the majority of OA-associated DNA methylation changes map to non-coding intronic or intergenic regions of the genome with enhancer features. However, the target genes of these putative enhancers are largely unknown as regulatory regions often do not regulate the nearest gene.
This project will use a range of molecular biology techniques and bioinformatics analysis to identify the target genes of these enhancers and what affect the OA- associated DNA methylation changes have on gene expression. The student will perform chromatin interaction analysis using Capture-C, a technique used to identify DNA loci that physically interact, to identify the promoters that interact with the OA-associated enhancers. To validate the function if the enhancers, cutting edge CRISPR/Cas9 nuclease genome editing technology will be employed to genetically ablate and epigenetically modify the regulatory element and evaluate if these perturbations affect the expression levels of the target genes.
This exciting studentship will derive valuable new molecular insights into OA pathogenesis by identifying genes subject to OA-associated epigenetic changes, some of which may be novel diagnostic and therapeutic targets.
