This was tested in people. That is the most reliable kind of research we share.
This was gene data analysis plus tests on cells in a dish, so it is still at the lab stage.
The short version
Researchers looked at gene data and brain scans to find clues about what raises the risk of a brain tumor called 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.
What was studied. Researchers used gene data from 12,488 people with 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 and 18,169 people without it. They compared that data with 587 brain scan measures, with chemicals found in brain tissue, spinal fluid, and blood, and with gene activity in 13 brain regions.
What they found. Six of the brain scan measures were linked with all types of 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. Higher activity of a gene called HEATR3, across all 13 brain regions, was linked with higher glioma risk. Lab tests in cells found HEATR3 was higher in glioma, was linked with worse outcomes for patients, and helped the tumor cells grow. Higher levels of a chemical called orotate in blood, spinal fluid, and brain tissue were linked with higher risk of glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary, one type of glioma.
What this means, and what it doesn't
What it could mean: This gives scientists new clues about what may drive 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. The gene HEATR3 and the chemical orotate are now targets they can study further. Nothing here changes the care you get today.
What it doesn't mean: This does not mean there is a new treatment, drug, or test for 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. The work was done with gene data and with cells in a dish, not by giving people a treatment. A link found this way is not proof that these things cause tumors in any one person. It is not a promise of a cure.
