This was done on cells in a lab, not in people. It is a very early step.
This was only a computer study of stored tissue, not a treatment tested in people.
The short version
Researchers found that a brain chemical called NPY is turned down in glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary.
What was studied. Researchers used computers to compare gene activity in stored brain tissue. They looked at 169 glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary samples, 510 lower grade glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary samples, 207 normal brain samples, and four more sets of data.
What they found. NPY and its main partner, NPY1R, were turned down in glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary. Genes tied to low oxygen, new blood vessels, tumor spread, and a weakened immune response were turned up. Tissue maps showed only a weak link between NPY and low oxygen, and that link varied a lot from patient to patient.
What this means, and what it doesn't
What it could mean: This gives researchers a clue about how glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary changes. It may help them understand what drives the tumor. It does not change the care you get today.
What it doesn't mean: This was a computer study of tissue samples that had already been collected. No one was given a drug or any other treatment. It does not mean NPY can treat a tumor. It is very far from everyday care, and it is not a promise of a cure.
