- Tested in people
This was done on cells in a lab, not in people. It is a very early step.
This was only done in cells in a dish and in mice.
The short version
In lab dishes and in mice, changing two proteins made 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 tumors smaller.
What was studied. Researchers used two 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 cell lines grown in a dish, plus tumors grown in mice. They lowered oxygen and changed the levels of certain proteins to see what happened.
What they found. Low oxygen made the 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 cells grow, move, and spread more. The cells also made more energy. In mice, lowering a protein called SCAF1 or raising one called COX7A2 made tumors smaller and lighter.
What this means, and what it doesn't
What it could mean: This helps explain how 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 cells make energy and keep growing. It points to a possible target that drug makers could try to aim at someday.
What it doesn't mean: This is early lab work in cells and in mice. No people were treated in this study. There is no drug from this that a doctor can give you now. It is very far from everyday care, and it is not a promise of a cure.
