Newly Identified Biomarker Detects And Regulates Spread Of Brain Tumors

... Researchers have identified a novel biomarker for brain tumors and have uncovered a potential role the marker may play when the tumor spreads or comes back after treatment. The biomarker, a protein known as "soluble attractin," is normally absent in the central nervous system and is undetectable in cerebral spinal fluid unless malignant astrocytomas are present in the CNS. This newfound ability to identify biomarkers for malignant astrocytomas means physicians will have a minimally invasive method to track the success of treatments. ...
