This was done on cells in a lab, not in people. It is a very early step.
This was only done in the lab on samples, not in patients.
The short version
Scientists built a lab test that lights up only when two markers linked to 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 are both present.
What was studied. Researchers made a small sensor that glows when it finds two markers, called miR-21 and miR-155. These markers are often high in people with 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. The team tested the sensor in the lab and in blood serum samples.
What they found. The sensor gave a strong glow only when both markers were there. One marker alone did not set it off. Other similar molecules did not set it off either. It also worked in blood serum samples, which are messy and hard to test.
What this means, and what it doesn't
What it could mean: This is early work on a possible way to spot 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 sooner. If it keeps working, it could one day become a blood test that helps doctors find glioma earlier. That is still a long way off.
What it doesn't mean: This is not a treatment, and it is not a cure. It is lab-stage work. The sensor was tested on samples, not on patients as part of their care. No one has shown it can find 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 in a real person. Your doctor cannot order this test today.
