This is a review of where the lab science is heading, not a test in people.
The short version
Scientists are studying whether cutting off a tumor's cholesterol supply could slow it down.
What was studied. This is a review of lab research that has already been published. It looks at how 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 take in and handle cholesterol, a fat that cells need.
What they found. Several studies suggest 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 pull in extra cholesterol. They do this through a surface part called the LDL receptor. A protein called IDOL can break down that receptor. The authors say boosting IDOL might leave fewer receptors on the cell, so less cholesterol gets in.
What this means, and what it doesn't
What it could mean: Tumor cells need fat to build and protect themselves. If that supply could be blocked, it might become a new way to treat 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 one day. Right now this is a way of thinking about the problem, not a treatment anyone can get.
What it doesn't mean: This is a review of lab work, not a new result and not a test in people. No one was treated here, and there is no new drug to ask about. The authors note tumor cells may make their own cholesterol to make up for the loss. The healthy brain also needs cholesterol, so safety is unknown. This is not a promise of a cure.
