This was done on cells in a lab, not in people. It is a very early step.
This was done only on cells in a lab dish, not in people.
The short version
In lab dishes, a gene called IRF1 changed how 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 responded to the standard chemotherapy drug.
What was studied. Researchers worked with 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 in a lab. They treated the cells with temozolomide, the standard chemotherapy drug for this tumor, and watched what happened to a gene called IRF1.
What they found. After chemotherapy, the cells had less IRF1. When the researchers lowered IRF1 on purpose, more cells went into a worn out, non dividing state. When they raised IRF1, some of that worn out state was reversed. IRF1 seemed to work through a second gene called OAS2, which also dropped after chemotherapy.
What this means, and what it doesn't
What it could mean: This may help explain why some 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 survive chemotherapy in a sleeping state instead of dying. Cells like that are thought to help the tumor come back. If that link holds up, these two genes could become targets for future drugs.
What it doesn't mean: This does not mean there is a new treatment. The work was done only on cells in a dish, not in animals and not in people. No patient was treated or tested here. Nothing about your current care changes because of this. It is not a promise of a cure.
