- Tested in people
This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells grown in a dish.
The short version
This was a lab test on brain tumor cells in a dish, not a test in people.
What was studied. Researchers used two kinds of human 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 grown in the lab. They tested a form of estrogen called estradiol, a drug that turns on a cell switch called GPER, and a drug that blocks that switch.
What they found. Turning on the GPER switch made the cells move more and spread into nearby areas more. The drug that blocked the switch cut down that effect. The cells also changed to a form that moves and spreads more easily.
What this means, and what it doesn't
What it could mean: It points to GPER as a possible target for future brain tumor drugs. Scientists may now look at whether blocking this switch slows tumor spread.
What it doesn't mean: This does not mean there is a new treatment. The work was done on cells in a dish, not in people or in animals. No one knows yet if blocking GPER helps a person with a brain tumor. This is very early science, and it is not a cure.
