Duration of award: 09 months (February 2025 to October 2025)
Research title: Genetic changes in the bile ducts in PSC
Summary
PSC Support has awarded £15,000 to Dr James Sun to study how cells in bile ducts change in PSC. This project will be the first study to identify the genetic changes in bile duct cells in people with PSC. Dr Sun will explore the biological impact of these genetic changes using an artificially created bile duct, known as “organoids” – a way of growing cells in 3D in the laboratory.
This study is known as a “pilot study”, which means it is the very first investigation using state of the art technology that is designed to test whether, and how, a further, full study can be undertaken.
What will Dr Sun do?
In this pilot study Dr Sun will apply state of the art DNA sequencing technology to identify genetic changes in bile duct cells. He will separately develop a laboratory 3D cell model called organoids that will be used to study the biological effect of the genetic changes he identifies and determine how they alter the behaviour of bile duct cells.
Why is this study important?
This pilot study could provide us with a detailed understanding of the biological processes involved when bile duct cells become diseased. The aim is to develop a larger study with potential to benefit patients in two ways:
- Identify new drug targets in the cell changes discovered to delay or reverse progression of PSC
- Lead to the development of genetic tests that identify which patients are at higher risk of progression or cancer development in PSC
Mission 2030 is an ambitious challenge and we can’t do it alone. We need your help to find the breakthrough people with PSC so desperately need.
It’s time we found effective treatments for PSC
