“…This is evidenced by the fact that the overexpression of Smurf2 has been shown to encourage the activation of the TGF-β-responsive promoter and induce EMT within human kidney cortical epithelial cells ( 107 ). Recent research has demonstrated that flavin-containing monooxygenase 2 can enhance the expression of Smurf2 and facilitate its nuclear translocation, resulting in tubular cell fibrogenesis and paracrine secretion ( 110 ). In addition, the E3 ligase, Arkadia/RNF111, regulates TGF-β signaling by degrading Smad7 ( 111 , 112 ).…”
