About the Project

Project Title: Developing targeted treatments for HNRNPU-related neurodevelopmental disorder using drug repurposing strategies.

Rare diseases affect over 3.5 million people in the UK and recent medical advances have provided the means to generate potential treatments for several rare diseases that have been studied to-date but have no treatment. Importantly, a large proportion (80%) of these diseases are caused by specific alterations (mistakes) in the genetic building blocks or DNA of affected patients. New scientific methodologies, such as gene therapy, have been developed which could enable us to replace or repair DNA mistakes, but such treatments are extremely expensive. Gene therapies also take time to develop and may not be an option for all rare disease patients. Hence, there is a need for having a multi-pronged approach including drug repurposing to find novel therapies for rare neurodevelopmental disorders (RNDDs). The focus of this proposal is drug repurposing for HNRNPU.

Heterogeneous nuclear ribonucleoprotein U (HNRNPU) syndrome is one such RNDD which leads to developmental delay and seizures. We will harness significant local expertise including ongoing work on developing AAV-9 gene therapy for HNRNPU-related disorder in this proposal. The underlying problem is that patients produce insufficient HNRNPU protein. Our overall goal is to develop new treatments to make this condition better. Specifically in this project, we will test the approach of drug repurposing using patient cellular models of HNRNPU syndrome to identify candidate drugs, to check if we are able to restore normal cellular functions. This is an essential first step in the pathway towards developing new treatments for HNRNPU syndrome.

Current modalities of treatment include supportive care for the developmental delay and attaining seizure control through use of multiple medications. This may or may not achieve good seizure control and hence, there is a real and urgent need to do better. HNRNPs including HNRNPU are linked to various diseases and knowledge gained from this proposal will be more widely applicable to all RNDDs.

Entry Requirements:

Candidates must have a first or upper second class honours degree or significant research experience. A real motivation and passion to transform the care and treatment provided for patients with rare diseases is an essential criterion for this application. In addition, candidates must be self-motivated, have the ability to think independently, use own initiative, have good communications skills and be well-organised including good time management. An MSc or experience in bioinformation, molecular genetics, including data mining, cell culture and in vivo studies would be desirable but not essential.

The Faculty of Health is offering a number of scholarships for the academic year 2024/5 for eligible students. This project is being considered for the Faculty, PGT>PGR and Underrepresented Student scholarship schemes. You do not need to apply more than once as your application will automatically be considered for all scholarships based on your eligibility criteria. Please see below for any additional requirements.
Students worldwide are welcome to apply but will need to fund the overseas fee difference of around £24,000 per year but will not be eligible for the Underrepresented Student scheme.
Additional requirements
PGT>PGR
We are accepting applications from current and past (who have graduated in 2022 & 2023) PGT students from the Faculty of Health.
Underrepresented Student
We are accepting applications for the University of Sheffield Research Scholarships for Black or Black British (of African or Caribbean heritage), Asian or Asian British (of Bangladeshi, Pakistani and Indian heritage) or multiple ethnic background including one of the ethnicity groups listed above.
The University of Sheffield is committed to increasing opportunities in doctoral research for particular minoritised students who are currently under-represented in our postgraduate research student population.
Candidates will be required to complete a declaration form and upload it to their application. Applicants with overseas fee status are NOT eligible for these awards.
