Funded PhD Opportunity

Investigating the links between expression, function and epigenetic regulation of microRNAs.

Subject: Biomedical Sciences


Summary

Background

MicroRNAs (miRNAs) are small, non-coding RNA molecules that regulate gene expression by interacting with messenger RNAs (mRNAs). There is much hope that microRNA profiling can be a potentially valuable tool for improving the prognosis, diagnosis and treatment of disease (1), but there remains a significant gap in our knowledge about how exactly they function.

In our laboratory, we are interested in how the regulation of specific miRNAs, and their gene networks, can contribute to disease progression. In particular we are interested in how epigenetic mechanisms, such as DNA methylation can impact upon miRNA expression in different diseases, including  cancer (2) and glaucoma (3).

The current project will investigate this by utilising a combination of in vitro, in vivo and in silico models to explore the regulation and functionality of various miRNAs, including miR-145 and the miR-200 family. This project brings together the research interests of the three listed supervisors, making it a strategic area of investigation for the Genomic Medicine Research Group.

Methods

The methods, equipment and expertise outlined below are routinely used in the laboratories of the supervisors. Papers featuring similar experimental approaches have been published by them (4-7).

*2D & 3D Cell culture (cell-lines, primary cells, spheroids) *PCR Expression Analysis of miRNA

*Analysis of DNA methylation in miRNA regions by MS-PCR, bisulfite sequencing, COBRA analysis

*Functional Analysis of selected miRNA - Transfection assays - Effect on protein expression (Western Blotting) - Validation of target(s) (PCR & luciferase reporter assay) - Cell behaviour bioassays (proliferation / apoptosis /invasion )

*Bioinformatic analysis & Data-mining of online (clinical) data repositories.

Aims & objectives

a.To identify and select miRNAs for investigation

b.To assess how methylation impacts upon expression of selected miRNAs

c.To identify targets and carry out functional analysis of selected miRNAs

d.To explore clinical significance of selected miRNAs through in silico analysis of online datasets

e.To evaluate the potential of miRNA (and methylation) profiling as diagnostic/prognostic biomarkers in disease

Skills Required of Applicant

*Good Laboratory skills

*Good oral and written presentation skills

*Good critical thinking and analytical skills

*Good IT skills

*Good work ethic and ability to work independently

*Experience of biostatistics and using statistical packages

*Interest in bioinformatic analysis

Funding

    The University offers the following awards to support PhD study and applications are invited from UK, EU and overseas for the following levels of support:

    Vice Chancellors Research Studentship (VCRS)

    Full award (full-time PhD fees + DfE level of maintenance grant + RTSG for 3 years).

    This scholarship will cover full-time PhD tuition fees and provide the recipient with £15,000 maintenance grant per annum for three years (subject to satisfactory academic performance). This scholarship also comes with £900 per annum for three years as a research training studentship grant (RTSG) allocation to help support the PhD researcher.

    Vice-Chancellor’s Research Bursary (VCRB)

    Part award (full-time PhD fees + 50% DfE level of maintenance grant + RTSG for 3 years).
