Early Detection of Colorectal Cancer via MicroRNAs
Posted by Xuan Pham | Perspectives in ResearchSince their discovery in the early 1990s and 2000s, microRNAs have been implicated in a variety of human conditions. Most recently, however, microRNAs are being scrutinized under a different light: not as causative agents in human diseases, but rather as potential guides for cancer detection.
