This was done on cells in a lab, not in people. It is a very early step.
This was only done on computers and on cells in a dish, not in people.
The short version
Scientists found a protein that sits on glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary cells, and they built a small molecule that sticks to it in lab tests.
What was studied. Researchers used computer programs to compare gene activity in glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary tumors and in normal brain tissue, using data from public databases. They then designed a small ring shaped molecule called a cyclic peptide and tested it on cells in the lab.
What they found. The computer analysis picked a protein called DLL3 as a top target. DLL3 was high in glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary and low in normal brain tissue. A peptide called IMP-3 was predicted to attach to DLL3 and stayed attached during computer simulations. A glowing version of it, MPA-IMP-3, built up in glioblastoma cells and glowed more strongly there than in normal brain cells.
What this means, and what it doesn't
What it could mean: This gives researchers a possible handle to grab onto glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary cells. The team's goal is to use a target like this to carry treatment straight to tumor cells and spare normal brain. That work has not been done yet.
What it doesn't mean: This does not mean a new treatment exists. The work was done on computers and on cells in a dish. No person has been given this peptide. It is very early stage research, and it is far from anything a doctor can offer at a clinic. It is not a cure and it is not a promise of one. Many ideas that look good in the lab never work in people.
