DMD gene in development and cancer

DMD gene mutations result in Duchenne Muscular Dystrophy, which gave the gene its name. However, new data from our and other laboratories indicate that DMD mutations trigger downstream multi-system abnormalities going far beyond the mechanical instability in myofibres. These alterations are diverse and affect proliferation and signalling in specific cells, mitochondrial functions and metabolism and even oncogenesis.
Moreover, cognitive deficits found in Duchenne patients are caused by distinctive molecular alterations resulting from DMD gene mutations in the brain cells. Given this increasing range of defects, identifying novel pathological mechanisms triggered by DMD mutations would advance our understanding of potential new roles of this largest human gene known in human health and disease.
The strategic aim of the three interdisciplinary PhDs is to expand DMD research into new areas by exploiting novel findings and high quality preliminary data. The projects are mutually supporting, creating the critical mass, using several animal models offering cross-species validation of findings and access to the university infrastructure across the faculties.
They also involve 10 external partners offering laboratory placements and an extensive range of expertise – so while the majority of work will be undertaken in Portsmouth, each PhD student will also spend a short period at a collaborating laboratory.
The scholarship covers tuition fees and an annual maintenance grant of £15,009 (UKRI 2019/20 rate) for three years. Scholarship recipients will also receive up to £3,000 for research project costs/consumables during the duration of the programme.
The work on this project will offer a broad-spectrum training including:
- Molecular and functional analyses in cancer cells
- Developmental and morphological studies in zebrafish
- Multi-omics data analyses
Using RNASeq and proteomics analyses we have evidence that, contrary to the current dogma, DMD mutations predominantly affect undifferentiated rather than terminally differentiated cells, in which we identified numerous abnormalities.
This project will investigate the developmental effects of DMD mutations to establish whether an early treatment could prevent irreversible damage. This part of the project will also exploit dystrophic zebrafish, thereby using a less sentient developmental model offering a unique platform for behaviour and morphology analyses (using equipment in the Portsmouth Zeiss Global Centre).
Importantly, the zebrafish model will be used for both this and the concomitantly run DMD brain study, creating the cross talk and cooperation opportunities for PhD students on these projects. Importantly, somatic DMD mutations have been associated with aggressive cancers. Given the commonalities in development and oncogensis, tumour formation might be a novel but related aspect of DMD gene dysfunction.
The unique multi-omics data already available to us will be studied and the bioinformatics integration performed in collaboration with the Han Lab at the Milner Institute, Cambridge. The functional impact of DMD gene in oncogenesis will be studied in cancer cells, in collaboration with the Sicinski Cell Cycle Machinery in Development and Cancer lab at Harvard.
Unravelling novel mechanisms triggered by DMD mutations in cancer might help developing new diagnostic and therapeutic tools for this condition – and the successful PhD candidate will join a team using multidisciplinary approaches to analyse gene functions in health and disease. This project also offers training in a range of techniques including multi-omics dataset analyses, cell culture in vitro, advanced microscopy and in vivo studies.
You'll need an upper second class honours degree from an internationally recognised university or a Master’s degree in an appropriate subject. In exceptional cases, we may consider equivalent professional experience and/or qualifications. English language proficiency is required at a minimum of IELTS band 6.5 with no component score below 6.0.
You would have studied one of these: cell biology, biochemistry, developmental biology, pharmacology, neuroscience or a related molecular area and you would be keen to learn new things.
