Selected projects

  • Investigating the regulation and function of the mRNA cap

  • We investigate the regulation and function of the mRNA cap, and use this information to develop new therapies targeted at inhibiting tumour cell and parasite growth and proliferation.

  • Human cells contain about 25000 protein-encoding genes. We are only beginning to understand how the cell co-ordinately controls expression of these genes. Our focus is on a modification of mRNA called the mRNA cap. The mRNA cap structure protects transcripts from degradation and recruits factors which mediate processing events. We have found that different signals which the cell encounters (developmental, immunological, oncogenic) can alter the rate and extent to which the mRNA cap forms, either across the transcriptome or on specific transcripts. Thus the mRNA cap is an integrator of cellular signalling information, which directs reshaping of the cellular proteome in response to external and internal signals.

  • The mRNA cap describes a collection of structures which form on the 5’ end of RNA pol II transcripts. Capping enzymes catalyse modification of the first few nucleotides to form the cap. Most of these enzymes are recruited to phosphorylated RNA pol II at the early stages of transcription, thus capping the transcript as it is being synthesised. One cap structure and the enzymes involved in its synthesis are shown below. Our research involves investigating how these capping enzymes function biochemically and how they influence gene expression. We look at how cellular signalling pathways influence the expression or activity of these enzymes to change the genes which are expressed.

  • How does the cell regulate formation of the mRNA cap?

  • We strive to understand the function of mRNA cap regulation in mammals, in health and disease. The mRNA cap is an important but poorly understood structure which recruits the enzymes and co-factors involved in RNA processing and translation initiation. We have recently discovered mechanisms by which mRNA cap formation is regulated by oncogenes, signalling pathways and developmental pathways, resulting in changes in transcription and translation, which impact on cellular fate and function. The enzymes which catalyse mRNA cap synthesis are emerging as integrators of cellular signals which govern cell physiology. Our challenge now is to understand how the regulation of the mRNA cap impacts on specific mechanisms of gene expression and cell function.

  • Currently we are investigating how mRNA cap formation is regulated during embryonic stem cell differentiation, in T cells and in response to oncogenes.

  • mRNA cap regulation in T cells: We are using mouse models to investigate how the mRNA capping enzymes are regulated following T cell activation. We investigate how T cell activation is dependent on the different cap methyltransferases. We use the latest gene expression analyses technologies to investigate the impact of the mRNA cap on gene expression. We use immunological techniques to investigate the impact of the cap on T cell activation and function. Project funded by an ERC grant.

  • mRNA cap regulation in embryonic stem cells: We investigate how the mRNA cap is regulated during different differentiation pathways. We investigate the impact of mRNA cap regulation on pluripotency and differentiation. We use the latest transcriptomic and proteomic analyses to understand the mechanisms by which the capping enzymes impact on cell function. Project funded by MRC Senior Fellowship and Lister Fellowship

  • Considering mRNA capping enzymes as therapeutic targets?

  • We are currently asking whether cancer cells with deregulated gene expression pathways are more sensitive to inhibition of mRNA capping than healthy cells. We have found that particular oncogenes sensitise breast cancer cell lines to inhibition of RNMT. This suggests use of RNMT inhibitors may be most successful therapeutically at treating cancers with these oncogenic mutations.

  • We are working with the Dundee Drug Discovery Unit to screen for inhibitors of the mRNA capping enzymes. Small molecule inhibitors will be used to explore the use of targeting mRNA capping in cancers and immune disorders.
