ABSTRACT
Inflammation and oxidative stress play a significant role in the pathogenesis of nonalcoholic steatohepatitis (NASH). Ethyl pyruvate (EP) is a novel anti-inflammatory agent and a potent reactive oxygen species (ROS) scavenger. Therefore, EP supplemented in drinking water may alleviate experimental NASH in this study (even though 0.3% of EP cannot attenuate the simple non-aggressive fatty liver). The methionine-choline-deficient (MCD) diet was given to the C57BL/6 male mice for 3 weeks to induce NASH. The NASH animals were randomized into 3 treatment groups animals in the MCD alone group were treated with normal drinking water alone; animals in the delayed EP group were given 3% (v/v) of EP supplemented in normal drinking water, the treatment started 10 days after MCD diet feeding; animals in the early EP therapy group were treated the same as the delayed EP group except that EP treatment started the same day when MCD diet was given; the control mice were fed with normal chow and treated with normal drinking water (n = 10 for each group). Compared to MCD group with normal drinking water, early EP treatment significantly decreased serum ALT and improved NASH histopathology; delayed EP therapy only attenuated NASH in 50% (5/10) of the animals. The beneficial effects were associated with decreased hepatic TNF-a and IL-6 mRNA expression on early 5 days, inhibited NF-kB activation, reduced liver tissue malondialdehyde levels, and decreased intestinal bacterial translocation (BT). In conclusion:
EP supplemented in drinking water attenuates experimental NASH.Palabras clave
