This was done on cells in a lab, not in people. It is a very early step.
This was only done with stored data and cells in a dish.
The short version
Researchers found a protein that may hint at how a slow-growing brain tumor will act.
What was studied. Researchers looked at a protein called PSMB8 in low-grade glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary, a slower-growing brain tumor. They used gene data from large public tumor databases. They also ran lab tests on tumor tissue and tumor cells.
What they found. PSMB8 levels were high in most tumors, including low-grade glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary. Lower levels went along with a lower tumor grade and a change in the IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary gene. In lab tests, higher levels went with more of an immune cell called the M2 macrophage. Higher levels also went with tumor cells spreading more.
What this means, and what it doesn't
What it could mean: Someday a test for this protein might tell doctors more about a person's tumor. It may also help show who could respond to treatments that use the immune system. Right now it is only a research clue.
What it doesn't mean: This is not a new treatment, and it is not a cure. The work used stored gene data, tumor samples, and cells in a dish. No one was treated in a trial. Years more testing would be needed before this changes everyday care.
