This was done on cells in a lab, not in people. It is a very early step.
This was only done in lab cells and in animals.
The short version
In lab tests, turning down a protein called TRIM38 slowed 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.
What was studied. 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 makes up about 50% of primary brain tumors. Researchers used two glioma cell lines in the lab, called LN229 and T98G. They turned a protein called TRIM38 up and down and watched what happened. They also tested lower TRIM38 in animals.
What they found. Both cell lines had high levels of TRIM38. When the team lowered TRIM38, the cells grew and moved less, and 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 growth in animals slowed too. When they raised TRIM38, the cells grew and moved more. TRIM38 seems to break down another protein, which switches on a growth signal in the cell.
What this means, and what it doesn't
What it could mean: Nothing about your care changes because of this study. It points to one protein that scientists may aim at with future drugs. That work would have to start over in people first.
What it doesn't mean: This does not mean there is a new treatment. The work was done in cells in a dish and in animals, not in people. No one has tested this in a patient. It is not a promise of a cure, and it is many years away from everyday care, if it gets there at all.
