Figure 4. Suppression of TGFβ-induced αSMA expression by GSH and catalase: ELISA data. Explants were cultured in the control medium or with 75 pg/ml TGFβ2 in the absence or presence of 10 mM GSH (A) or 300 units/ml catalase (B). The culture period was 2 days (A) or 3 days (B). Explants were then lysed for determination of αSMA and DNA. Each value represents the mean±SEM, n=8–14 (A) and n=6–8 (B). In each case, the p value indicates the significance of the difference between the value for explants cultured with TGFβ alone and those cultured with TGFβ plus the test substance. Con, control; GSH, glutathione; T, TGFβ2; Cat, catalase.
