The role of Rab46 in cardiovascular disease


Coronavirus information for applicants and offer holders

We hope that by the time you’re ready to start your studies with us the situation with COVID-19 will have eased. However, please be aware, we will continue to review our courses and other elements of the student experience in response to COVID-19 and we may need to adapt our provision to ensure students remain safe.

<h2 class="heading hide-accessible">Summary</h2>

Endothelial cells line the blood vessels and play a central role in vascular function. Weibel Palade bodies (WPBs) are specialized storage vesicles found specifically in endothelial cells (1). These vesicles contain a pool of readily made cargo that, upon release, control vascular events such as haemostasis, inflammation, angiogenesis and vascular tone. Inappropriate release of WPB cargo into the blood vessel lumen results in the pro-inflammatory and pro-thrombotic environment associated with cardiovascular disease. My research involves understanding the mechanisms underlying the release of WPB cargo and how these become perturbed in cardiovascular disease.

<h2 class="heading hide-accessible">Full description</h2>

<p>Recently, we described a novel Rab GTPase (Rab46) in endothelial cells that has GTPase and Ca2+ binding activities and is located on WPBs (2)(2). Thereby, this research project involves a range of techniques including;- cell culture, siRNA transfection, calcium imaging, biochemistry, MRI and confocal microscopy, to address the role of Rab46 in WPB trafficking and endothelial cell secretion. In addition, we will investigate how mutations in this protein may contribute to cardiovascular diseases and explore the association of Rab46 with other inflammatory diseases using data from the UK Biobank.</p> <p><strong>References:</strong></p> <p>Weibel, E.

<p>Please note these are not standalone projects and applicants must apply to the PhD academy directly.</p> <p>Applications can be made at any time. To apply for this project applicants should complete a<a href=""> Faculty Application Form</a> and send this alongside a full academic CV, degree transcripts (or marks so far if still studying) and degree certificates to the Faculty Graduate School <a href=""></a></p> <p>We also require 2 academic references to support your application. Please ask your referees to send these <a href="">references</a> on your behalf, directly to <a href=""></a></p> <p>If you have already applied for other projects using the Faculty Application Form this academic session you do not need to complete this form again. Instead you should email fmhgrad to inform us you would like to be considered for this project.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;s minimum English language requirements (below).</p>

<h2 class="heading heading--sm">Entry requirements</h2>

A degree in biological sciences, dentistry, medicine, midwifery, nursing, psychology or a good honours degree in a subject relevant to the research topic. A Masters degree in a relevant subject may also be required in some areas of the Faculty. For entry requirements for all other research degrees we offer, please contact us.

<h2 class="heading heading--sm">English language requirements</h2>
