This was done on cells in a lab, not in people. It is a very early step.
This was a lab analysis of gene data, not a treatment tested in people.
The short version
Researchers looked at where two proteins show up inside 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.
What was studied. Scientists reused gene data from 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 that another team had already collected. They sorted the tumor cells into four types, then checked how much DPP8 and DPP9 each type made.
What they found. The tumor cells sorted into four groups. These were astrocyte-like, mesenchymal-like, neural progenitor-like, and oligodendrocyte: A helper cell in the brain and spinal cord. It wraps nerve fibers in a fatty coat called myelin, which helps nerve signals move. An oligodendroglioma starts in cells that look like these. See the glossary progenitor-like. DPP8 and DPP9 levels were not the same across the groups. Astrocyte-like cells had the most DPP8, and mesenchymal-like cells came next. Cells with high DPP8 were also tied to things like cell adhesion and the matrix around cells.
What this means, and what it doesn't
What it could mean: This is early science about how 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 differ from one another inside the same tumor. It gives researchers a place to look next. It does not change any treatment a patient can get today.
What it doesn't mean: This does not mean there is a new drug or a new test. No people were treated in this study. It was a computer analysis of gene data from tumor samples. The findings are ideas for future research, not results from a trial. This is not a promise of a cure, and it is a long way from everyday care.
