Effect of TGF-β2 on the expression of MYOC protein in human primary cultured TM cells. TM cells were treated with 0, 1, 10, and 100 ng/ml TGF-β2, respectively, for 48 h. Relative MYOC protein expression was determined by Western blot. β-actin was used as an internal reference. The data are shown as the means±SEM from the four cell lines with one cell line conducted in triplicate. *P < 0.05 vs. 0 ng/ml; #P < 0.05 vs. 1 ng/ml; ΔP < 0.05 vs. 10 ng/ml.
