This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in cells and in animals, not in people.
The short version
Lab and animal work found a protein that seems to help glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary cells block immune attack.
What was studied. Researchers looked at a protein called TRIM14 in glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary cells and in tumor samples. They also removed TRIM14 from tumors in animals to see what changed.
What they found. TRIM14 levels were higher in cancers. In glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary, the protein was linked to how long people lived. Cells with TRIM14 held onto more PD-L1, a protein that blocks immune attack. When TRIM14 was removed, tumors in animals grew less.
What this means, and what it doesn't
What it could mean: glioma: A tumor that starts in the glial cells. Those are the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4. The grade says how the tumor is expected to act. See the glossary often does not respond to drugs that free the immune system to fight cancer. This work offers one possible reason why. TRIM14 and a partner protein called BRCC3 may be worth testing as new targets.
What it doesn't mean: This does not mean there is a new treatment. The work was done in cells and in animals, not in people. There is no drug for TRIM14 or BRCC3 that a patient can get. It is early lab science, far from everyday care, and not a promise of a cure.
