This was done on cells in a lab, not in people. It is a very early step.
This was only done on cells in a dish, not in animals and not in people.
The short version
A compound from a plant harmed glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary cells grown in a lab, but it has not been tested in people.
What was studied. Researchers tested a plant compound called plumbagin on human cells grown in a lab. They used glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary cells, colon cancer cells, and lung cells. They also grew the glioblastoma cells into small 3D clumps.
What they found. After 24 hours, the amount of living cells was measured at 28.3% for the glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary cells, 28.8% for the colon cancer cells, and 14.1% for the lung cells. When cells were then left alone to grow into new colonies, 1.1% of the glioblastoma cells survived, 0.5% of the colon cancer cells survived, and 0.2% of the lung cells survived. The compound also broke up the way glioblastoma cells stuck together and moved, and it damaged the inside of the cells.
What this means, and what it doesn't
What it could mean: Plumbagin can harm glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary cells in a dish. That gives scientists a reason to keep studying it. It says nothing yet about whether it helps a person with a brain tumor.
What it doesn't mean: This is not a treatment. The work was done on cells in a dish. It was not done in animals, and it was not done in people. No one knows if it is safe in the body or if it would shrink a tumor. It also harmed the lung cells in the test, so it is not gentle on normal cells. This is very early lab science and it is far from everyday care. It is not a cure, and it is not a promise of one.
