Effects of LH and/or OP on the amounts of (A) Mn-SOD, (B) Cu,Zn-SOD and (C) CATA expressions. The cells were treated with LH (10 ng/ml) alone or in combination with OP (100 μM) for 24 h. mRNA data are the mean ± SEM of four separate experiments each performed in duplicate and are expressed relative to the amount of GAPDH mRNA. Protein data are the mean ± SEM of four experiments each performed with separate cell preparations and are expressed relative to the amount of beta-actin protein. Different letters indicate significant differences (P<0.05), as determined by ANOVA followed by a Fisher's PLSD as a multiple comparison test.
