Low grade glioma research

Gliomas are categorised as either low grade (slow growing) or high grade (fast growing) gliomas. Our researchers are working hard to develop new treatments for low grade gliomas, as these tumours are often inoperable due to their location within the brain and may transform to become high grade.

Low grade gliomas can affect both adults and children and can be divided into many different types, including astrocytomas, ependymomasand oligodendrogliomas. Learn more about how tumours are graded.

Our discoveries in low grade gliomas

Our previous research into low grade gliomas has focused on identifying the genetic make up of low grade gliomas, understanding how different genes contribute to tumour development and developing new ways of monitoring patients.

Key genes discovered in low grade astrocytoma

The landmark discovery of the gene BRAF and its role in the development of low grade astrocytomas signified a great step forwards in the battle against this tumour type. The study, led by Professor Peter Collins at the University of Cambridge, has since led to the development of new diagnostic tests for pilocytic astrocytoma. This work has also resulted in clinical trials to investigate whether drugs that have previously been used to treat skin cancer are effective in blocking the activity of the BRAF gene in low grade astrocytomas.

Professor Denise Sheer's research has also led to the discovery of a specific mutation to the BRAF gene which contributes to the growth of low grade astrocytomas. This discovery may lead to the development of new drugs to target this mutation.

Novel MRI scanning method to predict switch from low to high grade tumours

A new MRI scanning technique which detects changes in low grade gliomas that may indicate that the tumour is becoming more aggressive has also been developed by Dr Jeremy Rees at the University College London Institute of Neurology. This landmark discovery will enable doctors to predict the transformation of a tumour at an earlier stage and change the patient's treatment accordingly.

Current research into low grade glioma

Seeking patterns in low grade glioma

Professor Sheer and her team are studying low grade glioma tissue to find genetic characteristics which distinguish a tumour from healthy cells. This will allow drugs to be developed that target the tumour cells alone, reducing the damaging side effects of treatment. This project is focusing on molecules called microRNAs, which have a role in controlling which genes are switched on and off.

Fusion genes

Professor Collins and his team have been investigating the role of the fusion gene KIAA1549:BRAF, which is commonly found in pilocytic astrocytoma but not seen in healthy tissue. The study will use brain stem cells to establish the role of the fusion gene in the growth and development of this tumour type.

Unlocking the origins of low grade glioma

Mutations to the enzyme IDH1, which has a role in the energy generating process within cells, has been linked to slow growing low grade gliomas. Researchers at UCL, led by Professor Sebastian Brandner, will use mouse models to study precisely how mutations to IDH1 influence the growth and development of tumours.

Testing a new drug combination in children with low grade glioma

Dr Susan Picton at the University of Leeds is heading up a clinical trial jointly funded with Cancer Research UK to determine the potential value of combining two complementary drugs in treating young people with low grade gliomas.
