This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells in a lab, not in people.
The short version
In lab dishes, a cheap drug already used for high cholesterol 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 die, and researchers worked out how it does it.
What was studied. Researchers treated 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 with gemfibrozil, a drug normally used to lower fats in the blood. They looked at how the drug changed the way the cells clean up their own waste, handle stress, and manage calcium.
What they found. The drug blocked the cells' waste cleanup system. That put the cells under stress and threw their calcium off balance. The energy centers inside the cells were damaged, harmful chemicals built up, and the cells died. A protein called PGC-1 alpha appeared to be a key control point in this chain of events.
What this means, and what it doesn't
What it could mean: This adds to the case for looking at gemfibrozil as a possible future treatment 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. It also points to a weak spot in tumor cells that other drugs might target. For now it is information for scientists, not a change to anyone's care.
What it doesn't mean: This does not mean gemfibrozil treats brain tumors in people. The work was done on tumor cells in a lab, not in patients. It has not been tested here in humans, and there is no proof it shrinks tumors or helps anyone live longer. It is not a cure. Do not start or change any medicine because of this study. Talk to your own doctor about your treatment.
