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 protein that certain childhood brain tumor cells rely on to keep growing.
What was studied. Researchers studied medulloblastoma, a brain tumor that starts in the cerebellum in children. They looked at how genes are switched on and off in tumor samples. Then they removed a protein called KDM2B from tumor cells and from mice.
What they found. In one group of these tumors, called Group 3/4, KDM2B sat on the switches of genes that help nerve cells grow up. That kept those genes turned off. When the team removed KDM2B, tumor growth slowed in lab cells and in mice.
What this means, and what it doesn't
What it could mean: KDM2B may be a good target for future drugs for high risk medulloblastoma. It gives researchers a clear place to aim next.
What it doesn't mean: This does not mean a new treatment is coming soon. The work was done in lab cells and in mice, not in people. There is no drug yet that a doctor can give for this. It is not a promise of a cure.
