This was done on cells in a lab, not in people. It is a very early step.
This was only done in lab cells and in mice.
The short version
Scientists found a gene that can slow glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary by damaging the tumor cell's energy supply.
What was studied. Researchers studied 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 in the lab. They also grew glioblastoma tumors in mice. They tested what a gene called LRRC4 does inside tumor cells.
What they found. LRRC4 sent tiny bubbles from one part of the cell to the mitochondria. Mitochondria are the parts of a cell that make energy. This broke the inner shape of the mitochondria, so the cells could not make energy well. The tumor cells then grew and spread less. Tumors with low levels of LRRC4 were linked to a worse outlook.
What this means, and what it doesn't
What it could mean: This points to a possible weak spot in glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary. If a drug could copy what this gene does, it might slow tumor growth. No such drug has been made or tested in people yet.
What it doesn't mean: This does not mean there is a new treatment. The work was done in cells in a dish and in mice, not in people. It is very early science, and it is years away from everyday care if it works at all. It is not a cure, and it does not change what your doctor can offer you now.
