TGFBR2 and renal fibrosis: Moreover, for the sake of exploring a definiterelationship between miR-302b and TGF-βR2 in renal fibrosis regulation, we promotedTGF-βR2 expression by transfecting designed TGF-βR2 plasmid into HK-2 cells andobserved restoration of collagen I and α-SMA expression compared to miR-302btransfection alone.
