Scientists 'Silence' Aggressive Brain Cancer Gene in Mice

Test Mice 
Glioblastoma multiforme
 
                A new experimental drug has been found to turn off a gene that is connected to an aggressive and incurable type of brain cancer in mice. Glioblastoma multiforme is a brain cancer that is responsible for 13,000 American deaths a year. The new experimental is uses nanotechnology, which is small enough to advance through the blood-brain barrier to make contract with the brain tumors. This nanotechnology will target the cancer causing gene in the cells and shut them off; this means that the cancer causing genes were silenced.
Gene Silencing
  
               According to the study in, Science Translational Medicine, the mice that were used in these experiments were given the new drug intravenously. The results showed that the mice lived 20 percent longer and their tumors shrank three to four times in size. This had shown amazing progression towards ending this terrible disease. This opens up many doors to different therapy resistances. Many experimental drugs that are used against Glioblastoma fail in clinical trials. The next step is to test this experimental drug in clinical trials, though many results in animal studies are different when used in human studies. Hopefully, silencing these genes and eliminating them from the scenario will allow more treatments to be effective.  

                This disease is the source of thousands of people yearly. I find it amazing that we have come up with such technology that allows us to shut down cancer causing genes. By shutting down these genes, we give ourselves the time to do more research on the cancer itself to see if there are ways to eliminate it completely. This can also open up more research into silencing other genes for other diseases. Nanotechnology can be the beginning of a new era of disease control.

  1. This is extremely fascinating. I really wonder how they composed this drug. Sure, it silences the genes that causes cancer, but the interaction must be so complex. This molecule probably needs a tag to deliver it straight to the brain. Furthermore, it has to stay unreactive until it reaches the brain. I also agree with your point on how technology has dramatically grown. Nanotechnology can be the solution to gene and disease control.
