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 dish, not in people.
The short version
In a lab dish, turning off one gene made 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 grow less and die more.
What was studied. Researchers worked with U-87 MG cells, a 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 cell line grown in a lab. They switched off a gene called EBLN1 in those cells and watched what happened.
What they found. Cells with EBLN1 switched off grew less. The drop in growth showed up as early as the second day. More of these cells died, and they had more breaks in their DNA. Two proteins that help repair DNA, called ATM and BRCA1, dropped to lower levels. When the team switched ATM back on, the DNA breaks went down and the cells grew again.
What this means, and what it doesn't
What it could mean: This is early lab work that helps explain how 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 repair their own DNA. That repair is one reason these tumors can resist treatment. EBLN1 may be worth studying further as a target, but nothing here changes care today.
What it doesn't mean: This does not mean there is a new treatment. The work was done only on cells in a dish, not in people or animals. No one was treated, and nothing was tested for safety. It is a long way from everyday care, and it is not a cure or a promise of one.
