Effects of Rz432 on MnSOD expression in RPE-J cells. (A) Quantification of MnSOD transcript levels measured in triplicate with reverse transcription PCR. β-Actin amplified in the same reactions was used as an internal control. PCR products were quantitated by SYBR green staining. A significant decrease in MnSOD transcripts was observed by 24 hours after treatment with Rz432 (P < 0.05). (B) Western blot for MnSOD protein levels from Rz432 or GFP-treated cells. MnSOD mRNA and protein levels returned to normal after 4 days, because of the transient transfection. This experiment was performed twice, with essentially identical results.
