Mir-938 microRNA precursor family
From Wikipedia, the free encyclopedia
miR-938 has been found to directly target the SMAD3 gene, which encodes the main downstream TGF-β polypeptide SMAD3. This microRNA is overexpressed in non-functioning pituitary adenomas (NFPAs) compared with normal pituitary tissue.[1] Downregulation of TGF-β signalling is likely to play a role in the regulation of signalling pathways in NFPA tumorigenesis, thus also implicating SMAD3 and miR-938.
