How far along is this research?
- Lab cells
- Animals
- Review
- Tested in people
This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in lab dishes and in mice.
The short version
Scientists found a protein in glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary stem cells that, when blocked, made the cells stop dividing.
What was studied. Researchers studied glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary stem and progenitor cells. They blocked a protein called KIF20A. They tested this in flat cell cultures, in small lab-grown clumps of cells called organoids, and in mice with tumors in the brain.
What they found. Blocking KIF20A made the cancer stem cells stop dividing. The cells shifted into a more mature, settled state instead of keeping on growing. Growth of the cells dropped sharply in these tests.
What this means, and what it doesn't
What it could mean: This points to a possible new way to attack glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary. Instead of trying to kill the cells, the idea is to force them to stop dividing and grow up. It gives researchers a target to keep studying.
What it doesn't mean: This does not mean there is a new treatment. The work was done in lab dishes and in mice, not in people. No one has tested whether blocking this protein is safe or helpful for a person with a brain tumor. It is a long way from your doctor's office, and it is not a cure.
