Meanwhile, gene levels and protein expression of renal fibrosis-related targets such as phospho-Smad2/3 (p-Smad2/3) (26–47%), Sma- and Mad-related proteins 2/3 (Smad2/3) (19–38%), transforming growth factor-β1 (TGF-β1) (36–63%), and alpha-smooth muscle actin (alpha-SMA) (58–86%) were also significantly reduced. Here, TGFB1 is linked to renal fibrosis.
