Project TitleA Novel RNA Therapeutic Candidate for Fibrotic Diseases
Track CodeLU2015-101
Short Description

A microRNA drug candidate that treats fibrotic diseases through the repression of TGF-β receptor expression. #therapeutics #anti-inflammatory #RNA #woundhealing 

Abstract

Northwestern researchers have identified an innovative therapeutic strategy to treat acute and chronic fibrotic diseases. Progression of fibrosis involves repeated cycles of inflammation, epithelial injury and repair, which in turn, causes scarring and tissue malfunction. Chronic fibrotic diseases, such as cystic fibrosis, often result in irreversible damage to the fibrotic organ and the need for transplantation. Currently, there is no available treatment to halt the progression of fibrosis. Northwestern researchers have identified a therapeutic candidate that capitalizes on the role of transforming growth factor beta (TGF-β). TGF-β is a cytokine that is normally released in response to injury to stimulate wound repair. However, its overproduction is associated with tissue scarring in the fibrosis process. This therapeutic candidate is a novel microRNA which can repress the expression of two canonical TGF-β receptors, TGFBR1 and TGFBR2, and substantially decrease downstream TGF-β signaling. Unlike current therapeutics which only offer temporary anti-inflammatory relief, this compound would be the first therapeutic to target a specific upstream modulator involved in the progression of fibrosis.
