This was done on cells in a lab, not in people. It is a very early step.
This was only tested on cells in the lab.
The short version
Scientists made a new chemical that killed glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary stem cells in lab tests.
What was studied. Researchers built 16 new versions of a chemical called GMQ. They tested the versions on human glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary stem cells grown in the lab.
What they found. These stem cells carry a channel called ASIC3. Turning that channel on for a long time kills the faulty cells. Brain tissue without ASIC3 was not harmed. The best new version, called 1a, acted on the stem cell clusters. It was also safer for normal cells and reached the brain better than GMQ.
What this means, and what it doesn't
What it could mean: This is very early lab work. It points to a possible new target in glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary. Researchers can now try to improve the chemical.
What it doesn't mean: This does not mean a new treatment is ready. The tests were done on cells in a dish, not in people. No one knows yet if this is safe or helpful for patients. It is not a cure, and it is far from everyday care.
