 This study suggests that umbilical cord-derived exosomes, MSC-X, can be used to treat liver fibrosis by reducing levels of L-Y-S-Y-L oxidase, like 2, L-O-X-L2. Exosomes contain micro-ionase, manas, which are small molecules that combine to specific genes and alter their activity. In this case, the researchers found that MSC-X contains a particular manner called MIR-27B-3P which can reduce levels of L-O-X-L2. They also discovered that this manner works by binding to a protein called yes-associated protein, YAP, and blocking it from interacting with the L-O-X-L2 gene. By doing so, they were able to decrease levels of L-O-X-L2 and prevent further damage to the liver. This article was authored by Fang Cheng, Fu Ji Yang, Yang Jin Wang, and others.
