This was done in animals, not people. Most findings at this stage never become treatments.
This was only tested in lab cells and animals, not in people.
The short version
Researchers studied how losing a gene called PDCD10 may help 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 tumors build new blood vessels.
What was studied. Scientists looked at 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, a fast-growing brain tumor. They turned down a gene called PDCD10 in tumor cells, then tested them in lab dishes, in chicken eggs, and in mice.
What they found. When PDCD10 was turned down, the tumor cells gave off signals that helped blood vessel cells grow. In mice, these tumors had many more blood vessels. Some tumor cells also started acting like blood vessel cells and like tumor stem cells, which can help tumors grow and resist treatment.
What this means, and what it doesn't
What it could mean: This helps explain how these tumors may feed themselves with new blood vessels. In the future, PDCD10 might become a target for new treatments. That idea still needs much more testing.
What it doesn't mean: This was done only in lab cells, chicken eggs, and mice, not in people. There is no new treatment from this study. It is very far from everyday care, and it is not a cure.
