Vitamin B12 based compound targets glioblastoma in animal tests
Original title: New vitamin B12 therapy shows promise against deadly brain cancer
How far along is this research?
This is a news item, not a research finding.
This was only done in animals, not in people.
The short version
Scientists built a compound based on vitamin B12 that reached brain tumors in animals.
What was studied. Researchers made a compound based on vitamin B12 and tested it in animals. They looked at whether it could cross the blood brain barrier and reach glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary tumors.
What they found. The compound crossed the blood brain barrier. In the animal studies, it built up more in tumor tissue than in other tissue. It also released a steady amount of nitric oxide right at the cancer cells.
What this means, and what it doesn't
What it could mean: This points to one possible way to get a drug into brain tumor tissue. For now it is an early idea being worked out in the lab and in animals.
What it doesn't mean: This does not mean there is a new treatment. The work was done in animals, not in people. No one knows yet if it is safe or if it helps a person with a brain tumor. It is not a cure, and it is many steps away from anything a doctor could offer you.
