S1839 Effect of Silybin in Patients With Chronic Hepatitis: Preliminary Results of a Multicentre Randomized Controlled Trial vs Placebo

A S L D A b st ra ct s levels were significantly decreased in UDCA group compared to control group. Microarray analysis revealed that gene expression of glutathione S-transferase (GST) ismarkedly increased in UDCA group compared to control group. Since Nrf2-activated genes such as glutamatecysteine ligase, catalytic subunit (Gclc), heme oxygenase 1 (HO-1) exert antioxidant effects, we next investigated mRNA expression levels of these genes by quantitative real-time PCR. Quantitative real-time PCR revealed the elevated expression of both Gclc and HO-1 in UDCA group. Conclusion : UDCA administration blocks progression of liver inflammation in NASH by inducing Nrf2-regulated antioxidant gene expression and reducing serum ROS levels.
