This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in lab cells and in mice.
The short version
Scientists found a protein that helps 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 cells stay alive under stress.
What was studied. Researchers looked at a protein called MCUB 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. They tested it in tumor cells, in mice, and in lab grown tumor models.
What they found. MCUB keeps calcium out of the cell's power centers. That helps tumor cells survive stress and keep growing. When MCUB was removed, the cells were harmed by stress and by radiation. A test compound called TF-PPAO blocked MCUB and slowed tumors in mice and in lab grown tumors.
What this means, and what it doesn't
What it could mean: This points to a possible new target for future 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 drugs. It may also help explain why radiation does not always work well on these tumors.
What it doesn't mean: This does not mean a new treatment is ready. The work was done in cells and in mice, not in people. TF-PPAO is an early test compound, not a drug you can get. It is not a cure, and your care does not change because of this study.
