Research Abstract |
In vitro experiments using isolated mouse hepatocytes demonstrated that trans-fatty acid but not cis-fatty acid exacerbates hepatocyte death via increasing mitochondrial oxidative stress, although both cis-fatty acid and trans-fatty acid induces fatty accumulation in hepatocytes. In vivo experiments using obese mice indicated that trans-fatty acid containing diet increases endoplasmic reticulum stress and oxidative stress, followed by hepatocytes ballooning and death whereas cis-fatty acid containing diet induces simple liver steatosis. In conclusion, our findings suggested that trans-fatty acid diet is a potent risk factor of steatohepatitis.
