...ee and Anindya Dutta have shown that microRNAs can suppress the overexpression of a gene called HMGA2. This gene is related to creation of fatty tissue and certain tumors, as well as diet-induced obesity. MicroRNA is a single-stranded RNA that is typically only 20-25 nucleotides long and is related to regul...Research team identifies additional genetic risk factors for Crohn's disease
.... When the research team used RNA interference to suppress the gene's activity in bacterially infected cells, decreased molecular action associated with autophagy confirmed that the process depends on ATG16L1 activity.
