The biomarker is called miR-138. It is "highly expressed in cancer stem cells compared to normal neural stem cells" (ScienceDaily). If I am thinking of this correctly, then I believe that means that it is more easily noticed in cancer cells than normal cells. So picking up on when the cancer is going to come back or expand can be determined with miR-138.
When miR-138 is depleted, the cancer cells are destroyed completely. This new treatment outdo's treatments such as gamma radiation and surgery. Oftentimes, those treatments allow re-growth to be a possibility, whereas miR-138 prevents that.
Here is a quote from Dr. Sampath:
" 'In this study we have identified a master regular, miR-138, which is essential for the progression and relapse of a deadly form of brain cancer. By targeting this regulator we can effectively prevent the recurrence of this lethal form of cancer. This promising finding will pave the way for the development of a novel therapy to successfully treat the aggressive forms of brain cancer.' " (ScienceDaily).
Out of all the articles I have read, I think this one completely baffles me. So far, from what I have researched, there have only been vaccines or treatments that can subdue the glioblastoma. But I have never heard of something that could possibly prevent the relapse and growth of the tumor.
