How far along is this research?
- Lab cells
- Animals
- Review
- Tested in people
This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in tumor cells and in mice.
The short version
This was lab work on brain tumor cells and mice, not a test in people.
What was studied. Researchers worked with two 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 cell lines in dishes. They treated the cells with the 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, with a body chemical called lactate, or with both, and they also grew tumors from one cell line in mice.
What they found. 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 lowered the growth signal of both cell lines and lowered lactate inside the cells, while adding lactate blunted some of the drug's effects. When the team turned down a protein called SYT8, the treated cells formed fewer colonies and more of them died. In the mice, tumors weighed the least when SYT8 was turned down and chemo was given.
What this means, and what it doesn't
What it could mean: It points to a possible new target that might make chemo work better one day. For now it mainly tells scientists where to look next.
What it doesn't mean: This does not mean there is a new treatment. The work was done in cells in a dish and in mice, not in people. No one knows yet if it would help a patient. It is very early science, far from everyday care, and it is not a promise of a cure.
