Project Description

Skeletal muscle is a major and important component of the mammalian body and the consequences of loss of control of the regulatory factors which govern skeletal muscle development can be fatal. One example is the serious heritable disease of Duchenne muscular dystrophy (DMD), but muscle atrophy is also a serious problem of old age. Using cultured stem cell models we have shown that dystrophic muscles undergo excessive cycles of cell death (apoptosis) and proliferation and have also shown that the growth factor (Igf-2) can modify this. We are now investigating the mechanisms by which IGF-2 exerts this control by examining both developing and ageing muscles as well as those with diseases such as DMD. To develop strategies for gene therapy of skeletal muscle diseases such as DMD we have developed an in vivo/in vitro stem cell model which is capable of delivering potentially curative genes (such as Igf-2) directly into target skeletal muscles. More recently we have begun to dissect the molecular pathway that regulates skeletal muscle cell death or survival and have identified one gene (PKB/pAkt) which plays a pivotal role in this pathway. Using a range of biochemical, molecular biology, genetic, cell and whole animal techniques (including the relatively new techniques of RNA silencing and microarray analysis) we are investigating the function of this pathway and why it is perturbed in muscular dystrophy (MD) as well as identifying potential (pro and anti-apoptotic) target genes that may be used to develop therapies to treat MD. Current projects include projects to analyse signal transduction pathways in MD and in the embryogenesis of skeletal muscle disease.

Please find additional funding text below. For further funding details, please see the ‘Funding’ section.
The School of Biosciences offers a number of UK Research Council (e.g. BBSRC, NERC) PhD studentships each year. Fully funded research council studentships are normally only available to UK nationals (or EU nationals resident in the UK) but part-funded studentships may be available to EU applicants resident outside of the UK. The deadline for applications for research council studentships is 31 January each year.

Each year we also have a number of fully funded Darwin Trust Scholarships. These are provided by the Darwin Trust of Edinburgh and are for non-UK students wishing to undertake a PhD in the general area of Molecular Microbiology. The deadline for this scheme is also 31 January each year.

Funding Notes

All applicants should indicate in their applications how they intend to fund their studies. We have a thriving community of international PhD students and encourage applications at any time from students able to find their own funding or who wish to apply for their own funding (e.g. Commonwealth Scholarship, Islamic Development Bank).

The postgraduate funding database provides further information on funding opportunities available http://www.birmingham.ac.uk/postgraduate/funding/FundingFilter.aspx and further information is also available on the School of Biosciences website http://www.birmingham.ac.uk/schools/biosciences/courses/postgraduate/phd.aspx
