Project Details:

This studentship aims to understand the influence of JAKMIP1 dysfunction on neural circuit activity in the cerebellar and cerebral cortices.  Autism is a major mental health issue affecting 1 in 100 people in the UK, defined by three core features, primarily impaired social interactions, language impairment, and repetitive or restricted behaviours. Along with the cerebral cortex, the cerebellum, or ‘little brain’, is increasingly implicated in the expression of autism-like behaviours. Autism has a strong genetic component, but the mechanistic links between behavioural phenotypes and molecular- and brain circuit pathology are poorly understood. Recently, dysfunction of janus kinase and microtubule interacting protein 1 (JAKMIP1), a regulator of neuronal translation and glutamatergic signalling, has been shown to contribute to both inherited and idiopathic autism. The JAKMIP1 protein is involved in core autism behaviours including social defects (Berg et al., Neuron 2015). To understand the molecular functions of JAKMIP1, we have knocked out JAKMIP1 in human neuroblastoma cells using the novel genome-editing technique, CRISPR-Cas9 system. We will identify the specific cellular cascades targeted by JAKMIP1 and investigate their links with autism. We will then explore how JAKMIP1 deficiency induces social dysfunction and motor coordination through altered neural circuit activity in the brains of JAKMIP1-KO mice.    

Experimental Design:   This project will combine novel cutting-edge techniques including bioinformatics, genome-editing, molecular cellular biology, microscopy and in vivo electrophysiology to address the following specific aims:  1. Identify potential therapeutic targets for modifying autism-associated neuronal and brain morphological phenotypes by:  
a. RNA-sequence data analysis (bioinformatics and Crispr genome engineering): Identify cellular pathway candidates for pharmacological modulation using JAKMIP1-KO neuroblastoma cells.  
b. Molecular biological analysis (neuronal morphological analysis and target pathway analysis in vitro): Detect target pathways of JAKMIP1 by examining protein/mRNA levels using western blot and qPCR.  
c. Brain anatomical screening (Immunohistochemistry and confocal microscopy): Measure the effect of Jakmip1 loss on development in the cerebellum and cerebral cortex.  

2. Characterise how JAKMIP1-deficiency alters information processing in neural circuits by: 
a. In vivo electrophysiological recording in Jakmip1-KO mice: Measure neuronal ensemble activity with NeuroPixels probes in the cerebellum and cerebral cortex of awake behaving animals.  
b. Functional neuronal connectivity in JAKMIP1 dysregulated brain: Assay strength and dynamics of synaptic connections using optogenetics in Jakmip1-KO mice.  

The successful candidate will establish the influence of a key autism risk gene on neural processing, potentially leading to new breakthroughs in diagnosis and intervention.


Funding

This studentship is funded through GW4 BioMed MRC Doctoral Training Partnership. It consists of full UK/EU tuition fees, as well as a Doctoral Stipend matching UK Research Council National Minimum (£15,009 for 2019/20, updated each year) for 3.5 years.

For further information relating to the funding please see the main MRC GW4 BioMed website

This project is in competition with a number of other projects across the partnership; up to 18 studentships in total will be available.  


Eligibility and Residency Requirements
To be eligible for a full award (fees and stipend) from a Research Council, a UK or EU student must have no restrictions on how long they can stay in the UK and have been ordinarily resident in the UK for at least 3 years prior to the start of the studentship.

An EU student who has not been resident in the UK for at least 3 years prior to the start of the studentship is generally eligible for a fees-only award from the Research Council: to be eligible for a fees-only award, a student must be ordinarily resident in a member state of the EU; in the same way as UK students must be ordinarily resident in the UK.

For our regular recruiting round, the Doctoral Training Partnership has additional funding from the partner universities to support a limited number of EU students who do not meet the UK residency requirements, so long as they meet the criteria for a fees-only award: these studentship will therefore be fully funded (fees and stipend).

For full details on eligibility, please refer to the MRC GW4 BioMed website

Students with 'International' status are unfortunately not eligible to apply.


Data Protection
If you are applying for a place on a collaborative programme of doctoral training provided by Cardiff University and other universities, research organisations and/or partners please be aware that your personal data will be used and disclosed for the purposes set out below.

Your personal data will always be processed in accordance with the  General Data Protection Regulations of 2018. Cardiff University (“University”) will remain a data controller for the personal data it holds, and other universities, research organisations and/or partners (“HEIs”) may also become data controllers for the relevant personal data they receive as a result of their participation in the collaborative programme of doctoral training (“Programme”).

Entry requirements

Academic criteria
In addition to those with traditional biomedical or psychology backgrounds, the DTP welcomes students from non-medical backgrounds, especially in areas of computing, mathematics and the physical sciences, and can fund additional training, including Masters to assist discipline conversion. Applicants for a studentship must have obtained, or be about to obtain, a First or Upper Second Class UK Honours degree, or the equivalent qualifications gained outside the UK, in an area appropriate to the skills requirements of the project. Applicants with a Lower Second Class degree will be considered if they also have a Master’s degree or have significant relevant non-academic experience.

English requirements
If English is not your first language you will need to have achieved at least 6.5 in IELTS (and no less than 6.5 in any section) by the start of the programme.

How to apply

Applications Open on 29 September and close at 17:00 on Monday 25 November 2019

The Research Theme Panels will complete the shortlisting and will aim to inform applicants by Thursday, 19 December 2019.  If you are shortlisted you will need to:

  • contact the lead supervisor of you chosen project in which you are interested, to arrange an informal interview (which can be in person, by telephone or by Skype) between 3 and 15 January 2020.  Please note that interview expenses will not be available for candidates to attend these meetings.
  • attend a formal interview, with a panel of four academics which will take place in Cardiff on 21 and 22 January 2020.
