A drug put glioblastoma stem cells to sleep in lab tests
Original title: Metabolic rewiring induces a viral mimicry-mediated quiescence in glioblastoma
How far along is this research?
This is a preprint. Other scientists have not checked it yet, so treat it as an early signal rather than an answer.
This was only done on cells in the lab, not in people.
The short version
In the lab, a drug made tumor stem cells stop growing and go into a resting state.
What was studied. Researchers studied 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 stem cells taken from patients and grown in the lab. They treated the cells with a drug called DENSpm to see if it would stop the cells from growing.
What they found. The drug raised a protein called SSAT1 in the cells. The cells then stopped growing and went into a resting state. That resting state could be undone. The resting cells also set off an immune alarm, the kind the body uses against viruses. When the team blocked part of that alarm, some cells started growing again.
What this means, and what it doesn't
What it could mean: This points to a possible new way to hold 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 still instead of killing them. For now it is only an idea being tested in the lab. It does not change any treatment a patient can get today.
What it doesn't mean: This does not mean a new treatment is near. The work was done on cells in a dish, not in people. The drug was not tested as a therapy for patients, so we do not know if it is safe or helpful for them. It is not a cure and it is not a promise of one. The study also found that the resting cells were shielded from chemotherapy. That could turn out to be a problem, not a win.
