MIT develops method of delivering RNA with tiny sponge-like spheres
For the past decade, scientists have been pursuing cancer treatments based on RNA interference — a phenomenon that offers a way to shut off malfunctioning genes with short snippets of RNA. However, one huge challenge remains: finding a way to efficiently deliver the RNA. MIT researchers have now come up with a novel delivery vehicle in which RNA is packed into microspheres so dense that they withstand degradation until they reach their destinations. The new system, described Feb. 26 in the journal Nature Materials, knocks down expression of specific genes as effectively as existing delivery methods, but with a much smaller dose of particles.
Among the research institutions NCI funds across the United States, it currently designates 66 as Cancer Centers. Largely based in research universities, these facilities are home to many of the NCI-supported scientists who conduct a wide range of intense, laboratory research into cancer’s origins and development. The Cancer Centers Program also focuses on trans-disciplinary research, including population science and clinical research. The centers’ research results are often at the forefront of studies in the cancer field.
