In a new Oxford Science Blog, Dr Pavandeep Rai (Department of Physiology, Anatomy and Genetics) guides us through her career and experiences of pushing the boundaries of science in both research and art.

Hard at work in the lab, Pavandeep works to unlock the secrets of Parkinson's

Dr Pavandeep Rai is a Post-doctoral Research Scientist in the Department of Physiology, Anatomy and Genetics. Her work focuses on the effect of something called 'mitochondria' on Parkinson's disease, using cutting edge gene-editing cool CRISPR-Cas. 

To start with, can you give us a beginner’s guide to your research? What is ‘mitochondria drug discovery’?

I started my ‘love affair’ with mitochondria during my undergrad degree at Birmingham, particularly in my year in industry with AstraZeneca. Basically, mitochondria are organelles, small entities within our cells. Their main job is to make something called ATP, which is the energy our cells use. So, if something goes wrong or your mitochondria start to degrade, then that will reduce the amount of energy and your cells don’t work as well.

The lab I’m working in looks specifically at Parkinson’s disease. By looking at the mitochondria, we can try to find ways to improve their functionality. Can we stop them from degrading? Once they’ve started, can we stop them from getting worse?

Currently, I’m using genetic editing tool called CRISPR-Cas. It’s been in the news recently, you might have seen those stories about ‘designer babies’ and the like? But we use it as a research tool to see how removing genes from the genome affects mitochondria.

If we remove a gene and it improves function, then we could maybe use it as a treatment for Parkinson’s.

If removing a gene decreases function in healthy cells, then that tells us something else. Perhaps this is one of the ways that the disease itself progresses?

So, it ties into two aspects of research: one is treatment and the other is understanding.
