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 mice.
The short version
In lab tests, blocking one molecule made brain tumor cells die in a new way.
What was studied. Researchers looked at a tiny molecule called miR-15a-5p 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 tissue and in tumor cells grown in the lab. They also turned the molecule off in mice with brain tumors.
What they found. glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary tissue and cells had much more of this molecule than normal. Patients with high levels lived a shorter time. Turning the molecule off slowed tumor cells from growing and spreading, and slowed tumor growth in mice. It worked by acting on a gene called GLS2, which set off a kind of cell death called ferroptosis.
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. It gives scientists a target to study for future drugs.
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 mice, not in people. No drug has been made or tested in patients yet. It is not a cure, and it will not change care today.
