This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in lab-grown cells and in animals, not in people.
The short version
Scientists found two targets in lab tests that slowed glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary cells from spreading.
What was studied. Researchers used glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary cells taken from patients and grew them in a gel that acts like brain tissue. They switched off genes one at a time to see which ones the tumor cells need in order to spread.
What they found. They tested 2,550 genes. Of those, 12 could be blocked by a drug and slowed the cells from spreading. Two of them, called AURKB and ACP1, held up in further lab tests and in living animals. Blocking either one changed a protein called cortactin, which the tumor cells use to move.
What this means, and what it doesn't
What it could mean: This points to two possible targets for future drugs aimed at stopping glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary from spreading into nearby brain tissue. It gives researchers a clearer path to follow.
What it doesn't mean: This does not mean there is a new treatment. The work was done in cells in the lab and in animals, not in people. No one has shown it helps a person with a brain tumor. It is not a cure, and it is many years away from everyday care, if it works at all.
