Project Update 17.04.2020

Current activities/Accomplishments:

I am currently concentrating on the writing up on 4 papers that have culminated from my project looking into the genetics of glaucoma. These concentrate on the generation of retinal organoids with development of retinal ganglion cells in a reduced timeframe compared to current methods, and complete characterization of these organoids compared to the development of the emerging eye.

This characterised retinal organoid system is followed by the development of a glaucoma disease model using CRISPR-Cas edited organoids to look at the molecular pathways involved in ganglion cell generation, and finally I’m taking critical look at the field of organoids and the increased variability between cultures with a view to initiate a standardised classification of organoid models and protocols.

Future plans:

I have submitted a grant to Uitzicht to continue my work on the CRISPR edited organoid system, and am currently in the final round of consideration, to which I should hear a decision in June. My long term future plans is to continue in research as a post-doc using the advanced techniques I have learnt during my PhD to earn a fellowship in a highly regarded institute.

My EGRET+ Experience:

I have been very fortunate during my project, having a large degree of freedom to direct the research down routes I found interesting. I have been able to visit many international labs and conferences to present my work and gain insight into other research. The collaboration between universities and the ease of organising secondments meant I could learn a vital new skill for my project, and be supported in an unfamiliar environment. All this would not be possible in other PhD projects, and I am grateful for the ITN that Marie Curie develops with this type of project. I can now go on to develop as an independent scientist, knowing I have gained a vital foundation of skills through EGRET Plus.

Background & Interests

My name is Philip Wagstaff, and I am from the Yorkshire in the United Kingdom. I moved to Liverpool to obtain my bachelor’s degree in Biochemistry and my subsequent master’s degree in Biomedical Science and Translational Medicine, specialising in Neuroscience. During my master’s I studied various neurodegenerative diseases such as Frontotemporal dementia, Amyotrophic Lateral Sclerosis (ALS), and Huntington’s disease using both model organisms and cell models. Here I learnt many things, including making genetic knock-out models, molecular biology and viral techniques, as well as acquiring a deeper understanding about the fundamentals of research. My interests are focused around neurodegeneration and incurable diseases, such as Alzheimer’s, Parkinson’s and Huntington’s Disease. In November 2016, I accepted the position in the clinical genetics department at the AMC in Amsterdam to start my PhD project.

Aim of the project

Glaucoma is a clinically and genetically heterogeneous group of diseases, with a final common pathway characterized by progressive retinal ganglion cell loss, optic nerve degeneration and, consequently, insidious visual field loss. Effective early treatment consists of early diagnosis and life-long lowering the ocular pressure using different drugs in different patients.

Several familial, monogenic and complex forms of glaucoma exist. For example, primary congenital glaucoma is a recessively inherited disease, caused, amongst others, by mutations in the CYP1B1 gene. Also, we and others recently found that the most common form of glaucoma, POAG, is caused by pathogenic variants in or near at least 65 genes, which are organized in four molecular pathways. These pathways are involved in (neural) development, lipid metabolism, neural disease and immune-related processes.

However, these pathogenic variants and pathways do not fully explain the molecular etiology or the variable expression of the disease in families and the population. In this project, we will genetically characterize over 1000 POAG patients, families and controls (GLGS and Lifelines) with a focus of identification of new disease genes in pedigrees and rare variants in complex POAG, molecular modelling and functional assessment. In selected pedigrees and in the population studies we will start selected gene (variant) analysis usually by Sanger sequencing followed by exome or whole genome sequencing. Genetic data will be pooled internationally, as usual, to gain power. We aim to find and characterized, where needed, new genetic glaucoma common and rare disease variants, improve the molecular modelling of POAG and other glaucoma disease types using bioinformatic integration of sequence, expression, and functional data.
