ABSTRACT
Objective To explore the role of ROS in TGF ?1 induced changes of plasmin system in rat mesangial cells. Methods Growth arrested and synchronized rat mesangial cells were stimulated by 2 ng/ml TGF ?1 for 12 h. In some experiments cells were pretreated with BSO for 24 h or with antioxidant NAC for 1h. Intracellular ROS production was visualized using a fluorescent dye.The mRNA expression of tPA, uPA and PAI 1 was measured by RT PCR and PAI 1 protein secreted into media by ELISA assay.The activities of plasmin, uPA, tPA were determined using a synthetic fluorometric substrate. Results TGF ?1 significantly increased intracellular ROS concentration. 2 ng/ml TGF ?1 significantly upregulated PAI 1 mRNA and protein expression by 1 9 fold(P
