Reversing the effects of pulmonary fibrosis with a microRNA mimic
A potential new treatment that reverses the effects of pulmonary fibrosis, a respiratory disease in which scars develop in the lungs and severely hamper breathing, is being studied by scientists. The treatment uses a microRNA mimic, miR-29, which is delivered to lung tissue intravenously. In mouse models, miR-29 not only blocked pulmonary fibrosis, it reversed fibrosis after several days.<img src="http://feeds.feedburner.com/~r/sciencedaily/~4/8IoVBKnPErQ" height="1" width="1"/>
