- Review
- Tested in people
This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in lab cells and in mice.
The short version
Blocking a protein that helps brain tumor cells handle stress slowed tumors in mice.
What was studied. Researchers looked at a protein called HSP27 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, a fast growing brain tumor. They lowered HSP27 in tumor cells, then tested it in mice with brain tumors.
What they found. Tumor cells use HSP27 to handle stress and keep their proteins working. When HSP27 was lowered, the cells made less protein and damaged protein built up. In mice, blocking HSP27 with a drug called Didemnin B slowed tumors and extended survival.
What this means, and what it doesn't
What it could mean: This points to a possible weak spot 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. It gives researchers a new target to study for future drugs.
What it doesn't mean: This does not mean a new treatment is ready. The work was done in tumor cells and in mice, not in people. No trial has tested this in patients, and no doctor can offer it today. It is not a cure. Many things that help mice do not help people.
