Brain tumors make a substance that may excite nearby nerve cells and help the tumor grow
Original title: Gliomas phenocopy an inborn error of metabolism to drive neuronal activity and tumor growth.
How far along is this research?
- Lab cells
- Animals
- Review
- Tested in people
This was done on cells in a lab, not in people. It is a very early step.
This was lab research on tissue and cells, not a treatment tested in people.
The short version
Scientists found that some brain tumors build up a substance that may help them grow.
What was studied. Researchers looked at brain tissue from people with fast-growing gliomas. They studied a substance called GAA and how it affects nearby nerve cells.
What they found. GAA was about 100 times higher in these tumors than in normal tissue. The tumor cells released GAA, and it made nearby nerve cells too active. When the researchers lowered GAA in tumors, the tumors became less active and less aggressive.
What this means, and what it doesn't
What it could mean: This gives scientists a new idea for how these tumors grow. Someday, blocking the tumor from making GAA might be a way to slow it down.
What it doesn't mean: This is very early lab research. It is not a treatment, and nothing was tested as a medicine in patients. It will not change your care today. It is not a cure.
