Modelling glioblastoma tumours to study the tumours' invasive properties.
Researchers at the University of Glasgow have created a new model to study the aggressive properties of glioblastoma, using mice that develop brain tumours which are highly similar to those affecting humans.
Glioblastomas are incredibly difficult to treat as they invade the surrounding brain tissue, causing distressing symptoms such as loss of speech and memory. It is crucial to understand the mechanisms that cause this invasion, however until now, models of glioblastoma within the lab have not accurately represented human tumours.
The team, led by Professor Anthony Chalmers, will be using the new pre-clinical model to investigate a biochemical pathway known as Rho, which is thought to control the ability of tumour cells to become mobile and infiltrate surrounding tissue.
If the model is successful, the team will test new drugs to target the Rho pathway and stop tumour invasion. They will also investigate whether the level of activity from the Rho pathway correlates with the extent of tumour invasion.
This could lead to more accurate diagnosis of glioblastomas and personalisation of treatment according to a patient's Rho pathway profile. The team will also develop a novel MRI imaging technique to measure the extent of tumour invasion in the brain.
A new pre-clinical model will be key to understanding the mechanisms behind glioblastoma invasion, which is essential to find new drug targets and develop new treatment options.
Research is the only way we will discover kinder, more effective treatments and, ultimately, stamp out brain tumours – for good! However, brain tumours are complex and research in to them takes a great deal of time and money.
Across the UK, over 100,000 families are facing the overwhelming diagnosis of a brain tumour and it is only through the generosity of people like you can we continue to help them.
But, by setting up a regular gift – as little as £2 per month - you can ensure that families no longer face this destructive disease.
