This was done on cells in a lab, not in people. It is a very early step.
This was done only in cells grown in a lab dish.
The short version
In a lab dish, a gene found in some brain tumors changed how young brain cells looked.
What was studied. Scientists made human brain stem cells in a lab from other human cells. They added EGFRvIII, a faulty gene seen in some 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 tumors, in two different ways.
What they found. Cells with the faulty gene made less of two proteins called SOX2 and nestin. These proteins are signs of young brain stem cells. Cells that made the gene all the time also showed more of a marker linked to cell aging. When the gene was switched on at a low dose, cell numbers changed in a different way.
What this means, and what it doesn't
What it could mean: The gene may act in different ways depending on the cell it lands in. That idea could help scientists learn how some brain tumors get started.
What it doesn't mean: This is lab work in cells in a dish. It is not a treatment, and it is not a cure. The authors say it does not prove the cells aged or turned into cancer. It also does not show where these tumors begin in a person. Nothing here changes care today.
