Metformin Improves Epithelial-to-Mesenchymal Transition Induced by TGF-β1 in Renal Tubular Epithelial NRK-52E Cells via Inhibiting Egr-1

Figure 3

Overexpression Egr-1 by M61-Egr-1 transfection promoting EMT in NRK-52E cells. NRK-52E cells were transfected by M61-Egr-1 before 10 ng/ml TGF-β1 stimulation. (a–c) The mRNA (a) and protein (b, c) expressions of Egr-1. (d–f) The mRNA expressions of E-cadherin, α-SMA, and FN. (g–j) The protein expressions of E-cadherin, α-SMA, and FN. Values are shown as mean ± SD. for each group. , , , , , and versus vector group.
