This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells in a dish, not in people.
The short version
Lab tests suggest the common chemo drug temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary can stop tumor cells from making protein.
What was studied. Researchers put temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary on RNA in the lab. They also treated glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary cells with the drug and watched what happened inside them.
What they found. The drug stuck stray chemical tags onto RNA. This damage acted like a roadblock, so cells made much less protein. The RNA hit hardest was the kind that is sturdy and used a lot. Much of that RNA helps cells grow and divide.
What this means, and what it doesn't
What it could mean: temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary is already a standard chemo drug for brain tumors. This work offers a new idea about how it kills tumor cells. Knowing how a drug works can help scientists use it better later on.
What it doesn't mean: This is not a new treatment. The work was done on cells in a dish and on RNA in the lab, not in people. It does not change how temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary is given today. It is not a cure, and it is not a promise of one.
