This was done on cells in a lab, not in people. It is a very early step.
This was only done in tumor cells grown in the lab, not in people.
The short version
In the lab, a drug switched off a set of genes that help 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 resist treatment.
What was studied. Researchers grew 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 from tumors in the lab. They treated the cells with a drug called JQ1. They also turned a gene called HOXA10 up and down to see what it does.
What they found. The drug quickly turned down a group of genes called HOX genes. These genes have been linked to poor outcomes and treatment resistance 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. Turning off the HOXA10 gene by itself did much the same thing. Those cells grew less, made fewer new cell clumps, and started to age. Adding extra HOXA10 did not undo the drug's effects.
What this means, and what it doesn't
What it could mean: This gives researchers a new target to aim at 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. If the finding holds up, it could help guide new drugs or new uses for drugs being studied. For now it adds to what scientists know about why these tumors resist treatment.
What it doesn't mean: This does not mean there is a new treatment. All of this work was done on tumor cells grown in the lab, not in people. No one was treated and no survival was measured. The drug used here is a research tool, not an approved medicine. Many lab findings never work in people. This is not a cure and it is far from everyday care.
