This was done on cells in a lab, not in people. It is a very early step.
This was only done with cells in the lab and with stored gene data.
The short version
Lab tests suggest one protein helps brain tumor cells resist being killed by copper.
What was studied. Researchers studied glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary cells in the lab. They also looked at gene data from several tumor databases to see how a protein called LAMC1 acts.
What they found. In the tumor data, high levels of LAMC1 went along with poorer survival. When the cells made more LAMC1, copper did less damage to them. When LAMC1 was turned down, the cells were easier to kill with copper. A drug called TTM, which soaks up copper, undid that effect and kept the cells alive.
What this means, and what it doesn't
What it could mean: This points to LAMC1 as a possible target for future glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary drugs. It may help explain why some tumor cells resist copper based damage. For now it is a clue for scientists, not a treatment a doctor can offer.
What it doesn't mean: This does not mean there is a new treatment. The work was done in cells in the lab and in stored gene data. No people were treated in this study. It is very far from everyday care, and it is not a promise of a cure.
