Hi! My name is Yizhou Yu and
I am a PhD student
at the University of Cambridge

My main research is in neurodegeneration and
I am particularly interested in Alzheimer's disease, sleep and mitochondria.

Research

Alzheimer's disease is the most common age-related neurodegenerative disorder. Familial forms of Alzheimer's disease associated with the accumulation of a toxic form of amyloid-β peptides are linked to mitochondrial impairment.

My research focuses on potential therapeutic targets for Alzheimer's disease using cell and fly models in combination with human genetic, biochemical, behavioural and brain imaging data. I recently used experimental results in flies to human medical records and showed that increasing the bioavailability of the coenzyme nicotinamide adenine dinucleotide to promote mitochondrial health could reduce pathologies related Alzheimer's disease (published in Cell Death & Disease, Yu et al., 2021) . I am now pursuing further research on the toxic effect of amyloid-β and how to reduce its toxicity.
I am also involved in a few collaborative works. In response to the COVID-19 pandemic, I completed research projects on how air pollution and neurodegenerative diseases could affect COVID-19 infection and death. I am also involved in a project on using machine learning to investigate the off-target effect of drugs on mitochondria.

Code and techniques

UK Biobank and functional genomics
The UK Biobank is a large cohort of 500 000 participants. I've published several work on the analysis of genetic, brain imaging, behavioural and medications data, using this resource. Please visit this repository for more information.

Drosophila research
I have been working with Drosophila melanogaster as a model organism for Alzheimer's disease. I am particular interested in measuring the function of their mitochondria as well as their sleep. I am familiar with all techniques listed here.

Cell cuture
I have been using differentiated neuroblastoma cells (SH-SY5Y) and rat neuroprecursor cells to model amyloid-β toxicity, and mitochondrial dysfunction. I'm also learning about organoids and iPSC.

Molecular modelling and dynamics
I have been developing several machine learning models to predict compounds binding to proteins, as well as using moecular docking and dyanmics to model the atomic interactions. One of the papers that I performed a molecular docking analysis is here

Parp mutations protect from mitochondrial toxicity in Alzheimer's disease

We analysed the metabolomic changes in flies overexpressing Aβ and showed a decrease of metabolites associated with nicotinate and nicotinamide metabolism, which is critical for mitochondrial function in neurons. We used combined results in flies and in humans to show that increasing the bioavailability of NAD+ protects against Aβ toxicity.

Links between air pollution and COVID-19 in England

We explored potential links between fuel-related air pollutants and SARS-CoV-2 mortality in England. Using regional-level data, we found positive relationships between nitrogen oxides and COVID-19 mortality and infectivity. Using the UK Biobank data, we further showed that PM2.5 was a major contributor to COVID-19 cases in England: an increase of 1 m3 in PM2.5 level was associated with a 12% increase in COVID-19 cases.

Alzheimer’s and Parkinson’s Diseases Predict Different COVID-19 Outcomes

We show that a pre-existing diagnosis of Alzheimer’s disease predicts the highest risk of COVID-19 and mortality among elderly individuals. In contrast, Parkinson’s disease patients were found to have a higher risk of SARS-CoV-2 infection but not mortality from COVID-19.

Paracetamol is associated with a lower risk of COVID-19 infection and decreased ACE2 protein expression

We showed that paracetamol intake was associated with a lower occurrence of COVID-19 in our cohort. We also found that paracetamol led to decreased ACE2 protein levels in cultured cells.

Public engagement initiatives

I an a co-founder at the International Sleep Charity!
Sleep is super important to maintain brain health. However, many factors including genetics and habitual can cause poor sleep. My role at the charity is to conduct research to find the causes for poor sleep and develop treatments to help people sleep better!

About Me

I am currently a PhD student in Dr L. Miguel Martins' research group. I previously graduated from Imperial College London in 2019 with a BSc in Biological Sciences (first-class honours). During my first degree, I completed internships with Dr Giorgio Gilestro to investigate sleep in flies as well as with Prof Masud Husain and Dr Michele Veldsman to investigate associations between poor sleep and neuroimaging markers.
In my spare time, I like to row and participate in hackathons.
