This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells grown in a lab dish, not in animals or people.
The short version
In lab dishes, a short form of one protein made 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 grow slower and die more easily under treatment-like stress.
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 grown in the lab, called 8MGBA. They compared normal 8MGBA cells with 8MGBA cells changed to make extra amounts of a stable short form of the SETMAR protein.
What they found. The cells with extra short SETMAR took longer to divide. Their cell cycle went from 27 to 37 hours, and the cells multiplied less. These cells also had damaged and unstable chromosomes. When put under stress meant to copy chemotherapy and radiation, more of them died.
What this means, and what it doesn't
What it could mean: This points to a possible new target for glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary treatment. The short form of SETMAR might one day help doctors judge how a tumor will behave, or help make tumor cells easier to kill with chemotherapy or radiation. For now it is a lead for more research.
What it doesn't mean: This is not a new treatment, and it is not a cure. The work was done only on cells in a dish. It was not tested in animals or in people. There is no way for a patient to get this today, and there is no promise it will ever work in a person. Many things that slow cancer cells in a lab do not help patients.
