Deciphering disease mechanisms underlying hypertensive pregnancy

Supervisors: Delyth Graham, Martin McBride

Project outline: The incidence of cardiovascular disease amongst women of child-bearing age is increasing. Consequently there is a greater prevalence of hypertensive disorders in pregnancy, in particular pre-eclampsia (PE), which is a leading cause of maternal and foetal morbidity and mortality. Despite its increased prevalence, the mechanisms underlying key pathological features of the disease remain unclear, and there are currently no effective clinical interventions.

The stroke prone spontaneously hypertensive rat (SHRSP) is an established model of human cardiovascular disease, which exhibits chronic hypertension during pregnancy1. This model can be progressed to the more severe pregnancy complication, superimposed PE, through angiotensin II administration mid-gestation2. Our recent studies in this model have identified pregnancy- and disease- dependent alterations in the uterine artery transcriptome relative to the normotensive control strain3. 

In this project, the specific molecules and pathways identified in our previous SHRSP studies will be explored mechanistically to determine their role in the pathogenesis of hypertensive pregnancy in order to identify new targets of therapeutic or diagnostic interest.

Techniques used: The student will receive training in a wide range of techniques, including animal models of hypertension and PE, cell culture, imaging, molecular biology approaches as well as RNASeq and other ‘Omics’ datsets and bioinformatic and pathway analysis. This PhD project will provide opportunities to develop an almost unique combination of in vivo, in vitro and molecular skills set.

Advancing precision nutrition in multimorbidity: strategies for reducing excess risk mortality (available as IPhD)

Supervisor: Dr Carlos Celis

MSc choices: Cardiovascular Sciences [MSc(MedSci)], Precision Medicine (with specialisms) [MSc], Public Health [MPH/PgDip/PgCert], Sport & Exercise Science & Medicine [MSc]

Project background: The global rise in people living with multiple chronic diseases, known as multimorbidity, presents a growing challenge. Currently, dietary guidelines adopt a 'one-size-fits-all' approach, offering the same nutritional advice to everyone, irrespective of their unique health conditions.

Our research team has recently made a promising discovery: shifting to a more sustainable diet could potentially extend life expectancy by up to 10 years. This finding is significant for both clinical practice and public health. However, the impact of adopting a more sustainable diet on the mortality risk and life expectancy of individuals with multimorbidity remains unclear.
For the first time, we are poised to explore how different dietary patterns affect those with multiple chronic illnesses and their associated mortality risks. This research is pivotal as it aims to identify the most beneficial dietary changes for people with multimorbidity, maximizing their health benefits.

The implications of our research are far-reaching. It has the potential to transform public health guidelines and clinical dietary recommendations, moving towards precision nutrition and medicine. This shift would be particularly beneficial for individuals with chronic conditions such as cancer, heart diseases, arthritis, and diabetes. Ultimately, our goal is to provide tailored, effective dietary advice that caters to the specific needs of those with multiple health challenges.

We are currently seeking enthusiastic students who are either planning to apply for scholarships or have already secured funding from their home countries or other research organisations. If this project intrigues you and aligns with your academic interests, we encourage you to get in touch to discuss potential PhD or postdoctoral opportunities.

Developing Therapeutic approaches for haemorrhagic stroke (available as IPhD)

Supervisor: Prof. Tom Van Agtmael

MSc choices: Biomedical Sciences [MSc], Cardiovascular Sciences [MSc(MedSci)], Clinical Pharmacology [MSc(MedSci)], Medical Genetics & Genomics [MSc(MedSci)], Precision Medicine (with specialisms) [MSc]

Research area: Mouse genetics, haemorrhagic stroke, molecular cell biology, extracellular matrix, vascular disease, collagen, endoplasmic reticulum stress

Project outline: Stroke costs UK Society ~£8 billion annually with haemorrhagic stroke accounting for 15% of adult and 50% of paediatric stroke. There are no treatment available for haemorrhagic stroke, in part due to a poor understanding of the underlying molecular cause.

Collagen IV is the major component of a type of extracellular matrix called the basement membrane that provides essential structural support to blood vessels. We and others have shown that mutations in COL4A1 or COL4A2 (encoding collagen IV proteins) cause familial and sporadic haemorrhagic, indicating these mutations may be more common than previously expected and a potential contribution to stroke in the general population (1). Our results also reveal that endoplasmic reticulum (ER)-stress due to intracellular accumulation of mutant collagen IV is associated with disease development, and that treatment of collagen IV mutant cells can reduce ER-stress (2). This provides a golden opportunity to identify the disease causing mechanisms and explore therapeutic approaches for collagen IV diseases including haemorrhagic stroke.

We have brought together a unique cohort of cell lines from patients and animal models with Col4a1 mutations to investigate the disease mechanisms of these mutations and determine how cells respond to these mutations. The identified pathways will then be modified in cell line and animal models to investigate their role in disease development and identify their potential as a therapeutic target. As FDA approved compounds are available, this will directly inform on and may identify therapeutic approaches for haemorrhagic stroke.

Project aims:

• Exploring genetic and high throughput approaches to identify pathways that influence disease development
• Identify the ability of small compounds to prevent the pathological effects of collagen IV mutation in cells.
• Modification of disease development in animal models

Techniques used: State of the art imaging techniques including 3-dimensional electron microscopy, confocal microscopy and atomic force microscopy. Molecular cell biology, animal models, MRI imaging, transcriptomics.

Exploring the health benefits of e-bike use compared to traditional non-electric bike commuting (available as IPhD)

Supervisor: Dr Carlos Celis

MSc choices: Cardiovascular Sciences [MSc(MedSci)], Precision Medicine (with specialisms) [MSc], Public Health [MPH/PgDip/PgCert], Sport & Exercise Science & Medicine [MSc]

Project Background: Our previous research has demonstrated that active commuting, particularly cycling, is associated with significant health advantages, such as a reduced risk of mortality and a lower likelihood of developing cardiovascular diseases. However, the specific health benefits associated with the use of electric bikes (e-bikes) remain largely unexplored. Our current research proposal aims to delve into the metabolic and health-related benefits of e-bike usage in comparison to traditional, non-electric bicycles.

This study will employ a hybrid approach, combining big data analysis with targeted interventions, to address the existing knowledge gaps in this area.

We are currently seeking enthusiastic students who are either planning to apply for scholarships or have already secured funding from their home countries or other research organisations. If this project intrigues you and aligns with your academic interests, we encourage you to get in touch to discuss potential collaboration opportunities.

Investigating disease mechanisms of collagen IV disease including intracerebral haemorrhage (available as IPhD)

Supervisors: Prof. Tom Van Agtmael, Dr. Alyson Miller

MSc choices: Biomedical Sciences [MSc], Cardiovascular Sciences [MSc(MedSci)], Medical Genetics & Genomics [MSc(MedSci)], Precision Medicine (with specialisms) [MSc]

15% of strokes are due to intracerebral haemorrhage (ICH), for which there is no treatment. and absence of specific effective treatments indicates increased knowledge of its pathomolecular basis is required. Recent genetic data has identified an important role for the protein collagen IV in stroke due to haemorrhage. Mutations in collagen IV also cause eye, kidney and muscle disease for there are also no treatments. We and others have showed the mutations and variants in collagen can cause defects to the extracellular matrix as well as a cell stress response called ER stress.

This project will use a powerful set of bespoke mouse models to determine in vivo the relative contribution of BM defects and ER stress to ICH as well as eye and kidney defects due to collagen IV. This will be combined with vascular physiology and molecular approaches, including transcriptomics and/or proteomics, to identify novel mechanisms.

Importantly, you will validate these mechanisms in patients. This project can be tailored to the interests of the candidate but will transform our knowledge of molecular mechanisms of stroke and disease due to collagen. This will aid development of precision medicine treatments.

Techniques used: you will be trained in a large variety of techniques crossing animal models of stroke, analysis of vascular function, molecular and biochemical approaches, imaging etc.

Investigating the extracellular matrix in vascular disease to develop treatments (available as IPhD)

Supervisors: Prof. Tom Van Agtmael, Prof. Delyth Graham

MSc choices: Biomedical Sciences [MSc], Cardiovascular Sciences [MSc(MedSci)], Medical Genetics & Genomics [MSc(MedSci)]

Vascular diseases including haemorrhagic stroke and vascular dementia formation are a major health problem for which there is an urgent need for treatments. Increasing our understanding of the underlying molecular disease mechanisms will aid in the development treatment strategies. We have previously identified that mutations in the genes Col4a1 and Col4a2 cause stroke and vascular disease. These mutations cause defects to the extracellular matrix and a cell stress response called endoplasmic reticulum (ER) stress, caused by misfolding of the mutant collagen protein. Deciphering the actions of these mutations has identified a number of new potential treatment targets that may be applicable for both genetic and common forms of stroke and vascular disease.

To address this gap in our knowledge, in this project you will employ a combination of mouse and rat models (e.g. SHRSP rat) that model vascular diseases including small vessel disease, the leading cause of vascular dementia. This analysis will be combined with additional novel animal models that we have already generated or that can be generated. Furthermore, this in vivo analysis will be coupled with investigating cell culture models, imaging and proteomics/next generation sequencing to determine the molecular mechanisms underlying vascular disease that leads to stroke and myocardial infarct. Finally, this will be coupled with either pharmacological or genetic manipulation of these mechanisms to identify new treatments that rescue the intracellular effects such as ER stress or that rescue the extracellular matrix by increasing its stability.

Techniques used: you will be trained in a large variety of techniques using animal models, cell culture, molecular and biochemical approaches, imaging, as well as RNASeq and proteomics etc.

Investigating mechanisms of stroke and small vessel disease (available as IPhD)

Supervisors: Prof. Tom Van Agtmael, Prof. Jesse Dawson, Dr. Lorraine Work

MSc choices: Biomedical Sciences [MSc], Cardiovascular Sciences [MSc(MedSci)], Clinical Pharmacology [MSc(MedSci)], Medical Genetics & Genomics [MSc(MedSci)], Precision Medicine (with specialisms) [MSc]

Stroke is a leading cause of death and disability and there is a real need for the development of new treatments. However, our incomplete understanding of the molecular mechanisms of stroke is severely hindering the ability to devise treatments that target the disease process that leads to stroke.

Over the past decade remarkable progress has been made in identifying genes that are associated with both stroke due to a brain clot or stroke due to brain bleeding. However the mechanisms by which these genetic variants act remain poorly understood. The overarching aim of this project is to help address this major gap in our knowledge using a combination of data science approaches (e.g. UK Biobank) coupled with analysis of mechanisms using advanced cell culture and animal models of stroke.
Projects Aims: Broad aims include determining the presence of genetic variants in the human genome that are associated with stroke in the general population. These variants will then be introduced via genome editing into cell culture models to drive forward the analysis of their mechanisms. A particular example here will be the manipulation of genes and proteins that are involved in maintaining the integrity and structure of the vasculature. Genetic data from ourselves and others have highlighted a key role for the extracellular matrix and enzymes that cleave secreted and transmembrane proteins in this process.

Techniques used: The student will be trained in the analysis of large datasets (UK Biobank etc) coupled with a wide array of genetic, molecular and cell biology approaches including but not limited to genome editing and genetic manipulation, vascular cell biology and use of animal models.

Investigating the mechanism of CD93 in cardiovascular and metabolic disease (available as IPhD)

Supervisors: Prof. Tom Van Agtmael, Dr. Rona Strawbridge 

MSc choices: Biomedical Sciences [MSc], Cardiovascular Sciences [MSc(MedSci)], Medical Genetics & Genomics [MSc(MedSci)]

Vascular diseases including haemorrhagic stroke and vascular dementia formation are a major health problem for which there is an urgent need for treatments. Increasing our understanding of the underlying molecular disease mechanisms will aid in the development treatment strategies.

CD93 is a transmembrane protein produced by endothelial cells. We have demonstrated that a reduction in CD93 levels in endothelial cells impairs endothelial cell function and endothelial layer integrity {Strawbridge, 2016 #49}. We have further demonstrated that the cleavage of CD93 to release sCD93 is increased in response to infectious stimuli, but this response is reduced by hyperglycaemia {Strawbridge, 2016 #49}. Reduced levels of sCD93 also precede and are associated with type 2 diabetes {Strawbridge, 2016 #49}. We have demonstrated that CD93 and sCD93 levels do not impact atherosclerosis {Strawbridge, 2016 #49}, but other mechanisms leading to vascular disease, particularly those in the brain, have not been investigated. Indeed, there is limited knowledge as to the purpose of CD93 cleavage and the role of sCD93.

To address this gap in our knowledge, in this project you will employ a combination of data science with molecular and cell biology approaches to investigate the genetic and molecular mechanisms of CD93. This project will combine analyses of large population cohorts to uncover the genetic architecture and regulation of CD93 alongside manipulation of CD93 levels and functional analyses of cell models. Genome editing of the cellular models can also be employed, depending upon genetic results.

Techniques used: you will be trained in a large variety of techniques including epidemiology, statistical genetics, in silico data mining, cell culture including CRISPR-based genome editing, molecular and biochemical approaches, imaging, as well as potentially RNASeq and proteomics etc.

Personalised management of blood testing for renal function in patients with and without diabetes (available as IPhD)

Supervisors: Paul Welsh, Patrick Mark

MSc choices: Cardiovascular Sciences [MSc(MedSci)], Precision Medicine (with specialisms) [MSc], Bioinformatics [MSc/PgDip/PgCert], Public Health [MPH/PgDip/PgCert]

The management of chronic diseases, including diabetes, accounts for 50% of clinical biochemistry testing. The number of clinical biochemistry tests requested is estimated to have increased by 10% annually for the last two decades. This has been due to a combination of complex clinical and management factors. However, there is a paucity of evidence that frequent testing actually improves patient care or alters clinical outcomes.

Scottish clinical guidelines for screening for kidney disease in diabetes patients states that estimated glomerular filtration rate and albumin-creatinine ratio should be assessed on an annual basis in people with diabetes, and that more frequent assessment may be necessary in adults with established chronic kidney disease (CKD). The guidance is similar in England and Wales. It is not clear how well these guidelines are adhered to in clinical practice. Beyond this, the evidence supporting this approach is derived from a health economics focused meta-analysis of randomized controlled trials, but does not take account previous measurements. For instance, those with good renal function may not require frequent re-testing.

Outside of the diabetes field, population based screening for renal function is not currently recommended. NICE guidelines suggest testing kidney function in people with risk factors for CKD such as hypertension, systemic disease (e.g. systemic lupus) or a family history of kidney failure. Anecdotal evidence from several sources suggests large numbers of creatinine tests are conducted in routine clinical practice. A data science approach might improve the evidence base for renal function testing for both targeting those at highest risk and optimizing follow-up. Furthermore, although blood testing for kidney function is widespread, measurement of urinary albumin to creatinine ratio is performed infrequently despite being a stronger predictor of cardiometabolic risk. Risk assessment tools exist but these were validated in populations with known CKD (not the general population) and do not account changes in risk factors over time. They are not in widespread use in the UK.

This project will explore the patterns of renal function testing in the NHS Greater Glasgow and Clyde area (>1million patients) and investigate evidence that might support an optimised approach to renal function testing in the general population and people with diabetes.

Training outcomes:

1. Experience in the use of medical statistics as applied to electronic health records, with further training if required.
2. Proficiency in the use of statistical software for medical statistics.
3. Conduct of systematic reviews of clinical guidelines.
4. Knowledge and experience of the structure of data in, and governance framework for, electronic health records as they relate to research.
5. Knowledge of the clinical guidelines for blood monitoring in chronic disease in the UK.
6. The student will also attend chronic disease review clinics; an established pathway under our flagship Clinical Observership Programme for basic scientists in our School.

Runx1 and Heart Failure (available as IPhD)

Supervisors: Dr C Loughrey, Dr S Nicklin, Ewan Cameron

MSc choices: Cardiovascular Sciences [MSc(MedSci)], Clinical Pharmacology [MSc(MedSci)]

Research area: Heart research

Project outline: Coronary heart disease (CHD) leading to myocardial ischaemia is the predominant cause of heart failure (HF) and premature mortality in the UK. CHD occurs when the blood vessels of the heart (coronary arteries) become narrowed by fatty material (atheroma) and reduce blood flow to heart muscle (myocardial ischaemia). If the coronary artery is occluded then an area of lethal tissue injury in heart muscle called a myocardial infarction (MI) can be produced. The subsequent structural and functional changes in the surviving heart muscle can lead to poor cardiac pump function and HF. Novel therapeutic strategies to preserve cardiac pump function are urgently needed to treat patients with myocardial infarction and thereby improve patient survival rates and quality of life.

The Runx family of genes (Runx1,2&3) encode for DNA binding transcription factors (Runx1,2&3) which regulate gene expression. Recently, increased Runx1 expression has been demonstrated in the hearts of patients with MI. In line with these data, our recent work demonstrates increased Runx1 expression in a mouse model of MI.

However, despite these observations, the role Runx1 plays in heart function remains unknown. We have made a novel and exciting discovery that higher Runx1 expression levels correlate with poor cardiac pump function. In order to corroborate this finding, we have produced a heart-specific knockout of Runx1. When MI is induced in this transgenic model, cardiac pump function is markedly improved suggesting that reducing Runx1 expression in the heart is a novel therapeutic approach to limit the progression of cardiac dysfunction in patients with MI.

Project aims: This studentship will investigate the relationship between Runx1 expression in the heart and the development of heart failure. In addition, the project will develop therapeutic strategies to reduce Runx1 expression in cardiac disease in order to prevent progression to heart failure.

Techniques used: The project will enable the student to be trained in in vivo rodent models of heart disease, integrative physiology, molecular biology and gene therapy approaches.

Tailoring physical activity recommendations for individuals with multimorbidity: moving beyond a one-size-fits-all approach (available as IPhD)

Supervisor: Dr Carlos Celis

MSc choices: Cardiovascular Sciences [MSc(MedSci)], Precision Medicine (with specialisms) [MSc], Public Health [MPH/PgDip/PgCert], Sport & Exercise Science & Medicine [MSc]

Project background: The global rise in people living with multiple chronic diseases, known as multimorbidity, presents a growing challenge. Currently, dietary guidelines adopt a 'one-size-fits-all' approach, offering the same nutritional advice to everyone, irrespective of their unique health conditions.

Our research team has recently made a promising discovery: shifting to a more sustainable diet could potentially extend life expectancy by up to 10 years. This finding is significant for both clinical practice and public health. However, the impact of adopting a more sustainable diet on the mortality risk and life expectancy of individuals with multimorbidity remains unclear.
For the first time, we are poised to explore how different dietary patterns affect those with multiple chronic illnesses and their associated mortality risks. This research is pivotal as it aims to identify the most beneficial dietary changes for people with multimorbidity, maximizing their health benefits.

The implications of our research are far-reaching. It has the potential to transform public health guidelines and clinical dietary recommendations, moving towards precision nutrition and medicine. This shift would be particularly beneficial for individuals with chronic conditions such as cancer, heart diseases, arthritis, and diabetes. Ultimately, our goal is to provide tailored, effective dietary advice that caters to the specific needs of those with multiple health challenges.

We are currently seeking enthusiastic students who are either planning to apply for scholarships or have already secured funding from their home countries or other research organisations. If this project intrigues you and aligns with your academic interests, we encourage you to get in touch to discuss potential PhD or postdoctoral opportunities.

Supervisors: Paul Welsh, Naveed Sattar

MSc choices: Cardiovascular Sciences [MSc(MedSci)], Precision Medicine (with specialisms) [MSc], Bioinformatics [MSc/PgDip/PgCert], Public Health [MPH/PgDip/PgCert]

UK Biobank is a uniquely large and well characterised prospective cohort study of ~500,000 adults in middle-age living in the UK. The study now has around 15 years of follow-up available and there is forthcoming linkage of all participants in the cohort to primary care data. This presents a unique opportunity to investigate the causes and consequences of many less common diseases (such as aortic aneurysms), and common diseases diagnosed in primary care (such as type 2 diabetes and dementia).

This flexible project presents an opportunity to the interested student to help design their own portfolio of data-driven work, and to be more widely involved in our highly successful UK Biobank working group which has led several seminal publications on the cohort 1-5. With experienced supervisors, the student can develop the area of interest and identify aims of interested based on literature review, and using this world-class data set and existing resources we have developed.

Training outcomes:

1. Experience in the use of medical statistics, including further training in medical statistics if required.
2. Proficiency in the use of statistical software for medical statistics.
3. Conduct of systematic reviews of the literature.
4. Knowledge and experience of the structure of electronic health care records in the UK.

Uromodulin a Precision Medicine Target for Novel Drug Discovery in Cardiovascular Disease (available as IPhD)

Supervisors: Delyth Graham, Martin McBride

MSc choices: Cardiovascular Sciences [MSc(MedSci)], Clinical Pharmacology [MSc(MedSci)], Precision Medicine (with specialisms) [MSc]

Background: Despite major advances in cardiovascular health, hypertension remains the risk factor contributing most to the overall burden of disease globally. When the total global impact of known risk factors on the overall burden of disease is calculated, 54% of stroke and 47% of ischaemic heart disease are attributable to hypertension.

In our recent genome-wide association study using an extreme case-control design, we discovered a SNP (rs13333226 at position 16:20365654) in the 5’ region of the Uromodulin gene (UMOD), also known as Tamm-Horsfall glycoprotein (THP) to be associated with hypertension. The minor G allele of rs13333226 was associated with lower risk of hypertension, decreased urinary uromodulin excretion, and higher glomerular filtration rate. Furthermore, the association with hypertension was shown to be independent of renal function indicating a possible pleiotropic effect, as SNPs highly correlated with rs13333226 were shown to be associated with kidney function in independent GWAS studies. The genotype association of rs13333226 and urinary UMOD excretion was more pronounced with low salt intake, and blunted with high salt intake, indicating a possible gene-environment interaction.

We have extended these findings with work in UMOD KO mice which show a lower baseline blood pressure and are not sensitive to salt induced changes in blood pressure. Our data indicate that UMOD has a role in BP regulation and may protect from salt induced increase in BP. UMOD is selectively produced in the thick ascending limb of the loop of Henle in the kidney. and exists predominantly as a polymer in luminal fluid.

Proposal Plan: Molecular characterisation of human and mouse uromodulin transcripts and binding partners.

In this project, we will utilise RNA from a large panel of human kidneys (~100) grouped according to hypertension status, as well as the UMOD knock out mouse. We have access to human and rodent RNAseq data that we will analyse using different strategies including biological pathways using gene set enrichment and Ingenuity Pathway Analysis. We are also interested in identifying binding partners of UMOD under different environmental stressors and assessing potential transcription factor binding in the promoter region using Electrophoretic Mobility shift Assays (EMSA).

Project aims

• Assess humanUMOD transcripts using RNAseq  Explore biological pathways using Ingenuity Pathway Analysis. 
• ValidateRNAseq gene expression changes using our panel of human kidneys prioritised by pathway analysis. 
• Use immunoprecipitation and mass spectrometry to identify binding partners of UMOD in human renal tissueto characterise potential mechanisms of action in disease.
• Assess the genetic contribution of UMOD in large scale data including UK Biobank

Techniques used: 

• Isolation ofDNA and RNA 
• qRT-PCR and Sanger sequencing
• PCRand cloning 
• Western analysis
• AnalysingRNAseq transcript data and other ‘Omic’ platforms
• Biological pathway and data integration analysis
• Electrophoretic Mobility ShiftAssays to identify potential binding partners of uromodulin and assess potential binding of predicted transcription factors using mass spectrometry.

Working in basic, translational and clinical research, our strength is in elucidating mechanisms of cardiovascular disease, identifying biomarkers of disease, identifying therapeutic targets and developing and designing novel therapeutic strategies that will lead to clinical trials.

Individual research projects are tailored around the expertise of principal investigators within the institute. Basic and clinical projects are available for study. A variety of approaches are used, including molecular biology, biochemistry, epidemiology, mathematical modelling, bioinformatics, genetics, cell biology (including advanced in vitro and in vivo imaging), immunology and polyomics (genomics, transcriptomics, proteomics, metabolomics etc).

Specific areas of interest include:

• vascular science and medicine
• cardiovascular biology and cell signalling
• cardiovascular gene therapy for the treatment of vascular disease
• basic and clinical cerebrovascular disease e.g. stroke 
• stem cell therapies for cerebrovascular disease
• genetics, genomics and systems medicine 
• adrenal corticosteroids in cardiovascular disease
• diabetes, obesity, metabolic and renal disease
• cardiovascular imaging
• cardiovascular clinical trials
• sport & exercise science & medicine
