Micro RNA seem to show promise in the area of regulating disease, fertilization and natural aging.however, the way of previously examining mi-RNA has not been as effective as possible, which is usually just found in many body fluids like saliva. There are over 1000 mi-RNAs in the body, and deregulation of them specifically are good markers for disease. For example, there is miR-16, which acts as a tumor supressor, which miR-223 acts as a pregnancy indicator. This new way of examining the mi-RNA involves more purification of the RNA. that is because plasma also seems to make it through all the purification levels that RNA makes it through. Hopefully, this new method of purification will allow more RNA to be tested, which can then be used to detect diseases earlier.
