Abstract BACKGROUND AND AIM: The aim of the present study was to evaluate the preventive role of genistein, a phytoestrogen with a wide variety of pharmacological effects, in an experimental non-alcoholic steatohepatitis (NASH) model. METHODS: Thirty-six Sprague-Dawley rats were divided into three groups. Group 1 (control) received only a standard rat diet, group 2 (placebo) was given a high fat diet (HFD) plus 0.5 mL/day saline subcutaneously, and group 3 (genistein group) a HFD plus subcutaneous genistein injection at dose of 0.2 mg/kg/day for 6 weeks. All rats were killed after 6 weeks. Serum aminotransferases, tumor necrosis factor (TNF)-alpha, transforming growth factor (TGF)-beta, and plasma and liver malondialdehyde (MDA) levels were measured. Additionally, steatosis, ballooning degeneration and inflammation of the liver were examined histopathologically. RESULTS: Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (P < 0.001 for each), plasma and liver tissue MDA and plasma TNF-alpha levels (P < 0.001, <0.001, <0.01, respectively) were found to be higher in the placebo group than in the control group. TGF-beta levels, however, were comparable in the placebo and control groups (P > 0.05). Histopathologically, steatosis, inflammatory cells per mm(2) and ballooning degeneration were significantly higher in the placebo group than in the control group (P < 0.001 for each). Nevertheless, AST and ALT (P < 0.05 for each), plasma and liver tissue MDA (P < 0.05 for each) and plasma TNF-alpha levels (P < 0.001) were significantly decreased in the genistein group compared to the placebo group. Histopathologically, steatosis (P < 0.05), inflammatory cells per mm(2) and ballooning degeneration (P < 0.01 for each) in the genistein group were also significantly lower than in the placebo group. CONCLUSIONS: Genistein, a strong antioxidant agent, significantly decreased the plasma TNF-alpha level and remarkably prevented the emergence of NASH by improving the biochemical and histopathological abnormalities via attenuating oxidative stress.

    Classically, the 3’untranslated region (3’UTR) is that region in eukaryotic protein-coding genes from the translation termination codon to the polyA signal. It is transcribed as an integral part of the mRNA encoded by the gene. However, there exists another kind of RNA, which consists of the 3’UTR alone, without all other elements in mRNA such as 5’UTR and coding region. The importance of independent 3’UTR RNA (referred as I3’UTR) was prompted by results of artificially introducing such RNA species into malignant mammalian cells. Since 1991, we found that the middle part of the 3’UTR of the human nuclear factor for interleukin-6 (NF-IL6) or C/EBP gene exerted tumor suppression effect in vivo. Our subsequent studies showed that transfection of C/EBP 3’UTR led to down-regulation of several genes favorable for malignancy and to up-regulation of some genes favorable for phenotypic reversion. Also, it was shown that the sequences near the termini of the C/EBP 3’UTR were important for its tumor suppression activity. Then, the C/EBP 3’UTR was found to directly inhibit the phosphorylation activity of protein kinase CPKC in SMMC-7721, a hepatocarcinoma cell line. Recently, an AU-rich region in the C/EBP 3’UTR was found also to be responsible for its tumor suppression. Recently we have also found evidence that the independent C/EBP 3’UTR RNA is actually exists in human tissues, such as fetal liver and heart, pregnant uterus, senescent fibroblasts etc. Through 1990’s to 2000’s, world scientists found several 3’UTR RNAs that functioned as artificial independent RNAs in cancer cells and resulted in tumor suppression. Interestingly, majority of genes for these RNAs have promoter-like structures in their 3’UTR regions, although the existence of their transcribed products as independent 3’UTR RNAs is still to be confirmed. Our studies indicate that the independent 3’UTR RNA is a novel non-coding RNA species whose function should be the regulation not of the expression of their original mRNA, but of some essential life activities of the cell as a whole.
