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 or people.
The short version
In a lab dish, snake venom killed brain tumor cells but left healthy brain cells alive.
What was studied. Researchers tested crude venom from a snake called the whitetail lancehead on rat and human glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary cells in a dish. They also tested two enzymes taken from that venom, leucurolysin-B and a basic phospholipase A2.
What they found. The venom killed glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary cells, and more venom killed more cells. At 3.0 micrograms per milliliter, the venom killed glioma cells while healthy brain cells called astrocytes stayed alive. Both enzymes also killed glioma cells without harming healthy human astrocytes, and leucurolysin-B was the stronger of the two.
What this means, and what it doesn't
What it could mean: This points to snake venom molecules as a starting point for new glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary drugs. The most useful part is that the venom hit tumor cells and spared healthy brain cells in the dish. That is an early hint, not a treatment.
What it doesn't mean: This does not mean snake venom treats brain tumors. The work was done only on cells in a dish, not in animals and not in people. Nobody knows yet if it is safe or if it works in a person. The authors say more studies are needed. This is not a cure, and it is many years away from everyday care. Do not seek out snake venom, it is dangerous.
