Does oxymatrine inhibit collagen synthesis in keloid fibroblasts via inhibition of transforming growth factor-β1/Smad signaling pathway?
OMT inhibited collagen synthesis, which might be associated with TGF-β/Smad signaling pathway. These findings suggest that OMT may be a promising candidate to prevent keloid and other fibrotic diseases.
In hepatocytes, bile acid-induced toxicity is not prevented by scavengers of oxidative stress. The beneficial effects observed in patients might be because of the contribution of ROS and cytokines rather than bile acid-mediated oxidative stress. However, the use of specific Src kinase inhibitors might be a useful tool to prevent bile acid-induced injury in liver diseases.
