This was done on cells in a lab, not in people. It is a very early step.
This was only done with cells in a lab dish.
The short version
Scientists studied cells in a dish to learn how a protein called DAXX affects tumor cell growth machinery.
What was studied. Researchers looked at a protein called DAXX in mouse cells and in human 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 grown in a lab. They lowered the amount of DAXX to see what changed.
What they found. DAXX sits on parts of the DNA that help make the cell's protein factories, and helps keep those parts switched off. In mouse cells, taking DAXX away loosened this switch, but the cells did not make more of the factory parts. In 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, lowering DAXX did make the cells build more of these parts. Data from past patients hint that a related protein, ATRX: A gene checked on the pathology report. Whether the tumor cells still make the ATRX protein helps sort a glioma into one type or another. See the glossary, may play a part in some brain tumors.
What this means, and what it doesn't
What it could mean: This helps scientists understand how some brain tumor cells may grow. Someday, ideas like this could point to new targets for treatment.
What it doesn't mean: This work was done only on cells in a lab. It was not tested in people or animals. It is not a new treatment, and it is far from everyday care. It is not a cure.
