Abstract
Alterations of methionine cycle in steatohepatitis, cirrhosis, and hepatocellular carcinoma induce MAT1A decrease and MAT2A increase expressions with the consequent decrease of S-adenosyl-L-methionine (SAM). This causes non-alcoholic fatty liver disease (NAFLD). SAM administration antagonizes pathological conditions, including galactosamine, acetaminophen, and ethanol intoxications, characterized by decreased intracellular SAM. Positive therapeutic effects of SAM/vitamin E or SAM/ursodeoxycholic acid in animal models with NAFLD and intrahepatic cholestasis were not confirmed in humans. In in vitro experiments, SAM and betaine potentiate PegIFN-alpha-2a/2b plus ribavirin antiviral effects. SAM plus betaine improves early viral kinetics and increases interferon-stimulated gene expression in patients with viral hepatitis non-responders to pegIFNα/ribavirin. SAM prevents hepatic cirrhosis, induced by CCl4, inhibits experimental tumors growth and is proapoptotic for hepatocellular carcinoma and MCF-7 breast cancer cells. SAM plus Decitabine arrest cancer growth and potentiate doxorubicin effects on breast, head, and neck cancers. Furthermore, SAM enhances the antitumor effect of gemcitabine against pancreatic cancer cells, inhibits growth of human prostate cancer PC-3, colorectal cancer, and osteosarcoma LM-7 and MG-63 cell lines; increases genomic stability of SW480 cells. SAM reduces colorectal cancer progression and inhibits the proliferation of preneoplastic rat liver cells in vivo. The discrepancy between positive results of SAM treatment of experimental tumors and modest effects against human disease may depend on more advanced human disease stage at moment of diagnosis.

Abstract
S-adenosylmethionine (SAM), biosynthesis from methionine and ATP, is markedly decreased in hepatocellularular carcinoma (HCC) for a diminution in ATP levels, and the down regulation of the liver specific MAT1a enzyme. Its metabolic activity is very important in the transmethylation reactions, the methionine cycle, the biosynthesis of glutathione (GSH) and the polyamine pathway, which are markedly affected in the HCC. The chemo-preventive effect of IFC305 in HCC induced by DEN, and the increase of ATP and SAM in CCl4-induced cirrhosis have been previously demonstrated. The aim of this work was to test whether this chemo-preventive effect is mediated by the induction of SAM biosynthesis and its metabolic flow. SAM hepatic levels and the methionine cycle were recovered with IFC305 treatment, restoring transmethylation and transsulfuration activities. IFC305 treatment, increased MAT1a levels and decrease MAT2a levels through modulation of their post-transcriptional regulation. This occurred through the binding of the AUF1 (binding factor 1 AU-rich sites) and HuR (human antigen R) ribonucleoproteins to Mat1a and Mat2a messenger RNAs, which maintained their nuclear localization. Finally, the compound inhibited the polyamine pathway favoring the recuperation of the normal methionine and one carbon cycle recuperating the metabolic flow of methionine, which probably facilitated its HCC chemo-preventive effect.

Abstract
Osteosarcoma is a very aggressive bone tumor. Its clinical outcome remains discouraging despite intensive surgery, radiotherapy, and chemotherapy. Thus, novel therapeutic approaches are demanded. S-Adenosylmethionine (AdoMet) is a naturally occurring molecule that is synthesized in our body by methionine adenosyltransferase isoenzymes and is also available as a nutritional supplement. AdoMet is the principal methyl donor in numerous methylation reactions and is involved in many biological functions. Interestingly, AdoMet has been shown to exert antiproliferative action in various cancer cells. However, the underlying molecular mechanisms are just starting to be studied. Here, we investigated the effects of AdoMet on the proliferation of osteosarcoma U2OS cells and the underlying mechanisms. We carried out direct cell number counting, MTT and flow cytometry-based assays, and immunoblotting experiments in response to AdoMet treatment. We found that AdoMet strongly inhibits proliferation of U2OS cells by slowing-down cell cycle progression and by inducing apoptosis. We also report that AdoMet consistently causes an increase of p53 and p21 cell-cycle inhibitor, a decrease of cyclin A and cyclin E protein levels, and a marked increase of pro-apoptotic Bax/Bcl-2 ratio, with caspase-3 activation and PARP cleavage. Moreover, the AdoMet-induced antiproliferative effects were dynamically accompanied by profound changes in ERK1/2 and STAT3 protein and phosphorylation levels. Altogether, our data enforce the evidence of AdoMet acting as a biomolecule with antiproliferative action in osteosarcoma cells, capable of down-regulating ERK1/2 and STAT3 pathways leading to cell cycle inhibition and apoptosis, and provide a rationale for the possible use of AdoMet in osteosarcoma therapy.

Abstract
In this work, we have investigated the antiproliferative effect of AdoMet and Doxorubicin (Doxo), alone or in combination, on different breast cancer cell lines. For the evaluation of synergism, we have calculated the combination index (CI) by the Calcusyn software and we have evaluated the effects of the combination on apoptosis occurrence at FACS analysis in hormone-dependent CG5 cell line. We have found that AdoMet and Doxo given in combination were strongly synergistic in the hormone-dependent CG5 and MCF-7 human breast cancer cell line, as a CI50 < 0.5 was found after 72 h of treatment while the effect was only additive in hormone-independent MDA-MB 231 cells. On the basis of our results, we have selected a combination of AdoMet and Doxo, that was highly synergistic and we have found that the AdoMet in combination with Doxo increased apoptosis induced by Doxo alone, suggesting that the synergism on growth inhibition was largely due to apoptosis. Notably, the AdoMet/Doxo combination induced a significant activation of caspases 3, and 8, while no effect was found on caspase 9 cleavage. In contrast, no significant changes of the expression of cleaved caspase 8 and 9 were found in cells treated with AdoMet and Doxo alone. Moreover, the combination induced a significant increase of Fas and FasL expression. These results highlight the importance of the synergistic effect of AdoMet with Doxo in the regulation of hormone-dependent breast cancer cell proliferation and emphasize the anti-tumor activity of these molecules.

Abstract
Liver stem/progenitor cells (LSPCs) are able to duplicate themselves and differentiate into each type of cells in the liver, including mature hepatocytes and cholangiocytes. Understanding how to accurately control the hepatic differentiation of LSPCs is a challenge in many fields from preclinical to clinical treatments. This review summarizes the recent advances made to control the hepatic differentiation of LSPCs over the last few decades. The hepatic differentiation of LSPCs is a gradual process consisting of three main steps: initiation, progression and accomplishment. The unbalanced distribution of the affecting materials in each step results in the hepatic maturation of LSPCs. As the innovative and creative works for generating hepatocytes with full functions from LSPCs are gradually accumulated, LSPC therapies will soon be a new choice for treating liver diseases.

Abstract
Epigenetic processes play a key regulatory role in many cancers. Recently, it also has been demonstrated to participate in fibrogenesis, especially in fibrotic disease. Fibrotic disease is a pathological response to tissue injury which can occur in any organ. Mechanisms that orchestrate fibrotic disorders in different organs are amazingly generic, involving generation of activated fibroblasts and myofibroblasts by differentiation processes that require extensive alterations in gene expression. Apart from genetic and environmental factors, epigenetic modifications including a combination of microRNAs and DNA methylation are supposed as regulatory mechanisms to control myofibroblast differentiation. It has become obvious that microRNAs, which act as regulators of gene expression at a post-transcriptional level, are differentially expressed in differentiating cells and play important roles in governing DNA methyltransferases (DNMTs) which are enzymes responsible for setting up and maintaining DNA methylation patterns at specific regions of the genome. Some microRNAs targeting DNMT transcripts lead to the demethylation and transcriptional activation of numerous protein coding gene sequences, thereby contributing to gene expression. Moreover, DNMTs also have a critical role in controlling some specific microRNA expression. This cooperative action among DNMTs, microRNAs and DNA methylation indicates that DNMTs may participate in the pathogenesis of myofibroblast differentiation through silencing of certain gene transcription. In this review, we summarize the current knowledge of a potential link between microRNA expression and DNA methylation on how DNMTs work in the process of fibrogenesis.
