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 dish, not in people.
The short version
In lab dishes, lowering one protein made brain tumor cells grow and spread less.
What was studied. Researchers looked at a protein called gp96 in 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 grown in the lab. They lowered the amount of gp96 and watched how the cells behaved. They also checked a cell signal called NF-kB.
What they found. gp96 levels were high in the 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. When gp96 was lowered, the cells grew less, moved less, and spread into nearby areas less. Lowering gp96 also turned down the NF-kB signal. When the researchers switched that signal back on, the cells grew and spread again.
What this means, and what it doesn't
What it could mean: This points to gp96 as a possible target for future 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 treatments. Right now it is a clue about how these tumor cells grow. It does not change any care a patient gets today.
What it doesn't mean: This was done only on cells in a dish. It was not tested in people, and not even in animals. There is no drug from this work that a patient can ask for. The study gives no numbers about how long anyone lived. It is very early science, and it is not a cure or a promise of one.
