A tiny molecule slowed glioma growth in lab and mouse tests
Original title: miR-506-5p targets MAPK7 to impede glioma growth and invasion through suppressing epithelial-mesenchymal transition and matrix metalloproteinases.

- Lab cells
- Animals
- Review
- 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 lab dishes and in mice.
The short version
In lab tests, a tiny molecule called miR-506-5p slowed 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 cells down.
What was studied. Researchers studied 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 tissue and glioma cells grown in a lab. They raised or lowered a tiny molecule called miR-506-5p, and also tested it in mice.
What they found. 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 tissue had less miR-506-5p and more of a protein called MAPK7. When the team raised miR-506-5p, the cells grew, moved, and spread less. In mice, raising it slowed tumor growth.
What this means, and what it doesn't
What it could mean: This points to a possible target for future 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 drugs. For now it is a lead for scientists to follow. It does not change the care a patient gets today.
What it doesn't mean: This is early work in lab dishes and in mice. It was not tested in people at all. There is no drug you can ask for based on this. It is not a cure, and it is not a promise of one. Work like this takes many years, and most of it never becomes a treatment.
