Abstract
The activation of hepatic stellate cells (HSCs) has been considered one of the major events in hepatic fibrosis. Amygdalin has been used to treat cancers and alleviate pain; however, its role and mechanism in HSC activation and hepatic fibrosis remain unclear. In the present study, transforming growth factor-beta 1 (TGF-β1) stimulated the activation of HSCs, as indicated by significantly increased alpha-smooth muscle actin (α-SMA), desmin, collagen I, and tissue inhibitor of metalloproteinase-1 (TIMP-1) protein levels. Amygdalin treatment dramatically suppressed TGF-β1-induced HSC proliferation and activation. Moreover, amygdalin treatment also reduced the TGF-β1-induced secretion of cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin 6 (IL-6), platelet-derived growth factor (PDGF), and chemokine (C-C motif) ligand 2 (CCL2), as well as the phosphorylation of Smad2, Smad3, and p65. In the CCl4-stimulated liver fibrosis rat model, amygdalin treatment improved liver fibrosis and liver damage by reducing focal necrosis, collagen fiber accumulation, and the protein levels of α-SMA, desmin, collagen I, and TIMP-1 in hepatic tissue samples and reducing serum alanine transaminase (ALT) and aspartate transaminase (AST) levels. In conclusion, we demonstrated the suppressive effects of amygdalin in TGF-β1-induced HSC activation through modulating proliferation, fibrogenesis, and inflammation signaling in vitro and the antifibrotic effects of amygdalin in CCl4-stimulated hepatic fibrosis in rats in vivo.

Abstract
In the present study, to verify the effect of polysaccharides derived from persimmon leaves (PLE) at epithelial-to-mesenchymal transition (EMT), A549 cells were treated with TGF-β1 alone or co-treated with TGF-β1 and PLE (50 and 75 μg/mL). PLE-treated cells showed higher expression of E-cadherin and lower expression of N-cadherin and vimentin compared to TGF-β1-treated cells by inhibiting the levels of transcription factors, including Snail, Slug, and ZEB1, all associated with EMT. PLE also significantly decreased migration, invasion, and anoikis resistance through TGF-β1 mediated EMT suppression, whereby PLE inhibited the levels of MMP-2 and MMP-9 while cleaving PARP. These inhibitory effects of PLE against EMT, migration, invasion, and anoikis resistance were determined by activating the canonical SMAD2/3 and non-canonical ERK/p38 signaling pathways. Therefore, these results suggest that PLE could be used as a potential chemical therapeutic agent for early metastasis of lung cancer in vitro.

Abstract
Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease with limited treatment options. Zingerone found in ginger (Zingiber officinale L.) has many pharmacological effects, especially antiinflammatory and antioxidant activity. However, the effect of zingerone on pulmonary fibrosis (PF) is not fully known. The aim of this study was to investigate the effect of zingerone on bleomycin (BLM)-induced PF and its underlying mechanisms. Wistar-albino rats were given single dose of BLM (5 mg/kg, intratracheal) or vehicle (saline). In treatment groups, zingerone (50 and 100 mg/kg, p.o.) was administered orally for 14 days after BLM administration. Rats and lung tissue were weighed to determine lung index. Antioxidant, antiinflammatory effects, and hydroxyproline content of zingerone were determined by ELISA method. Pulmonary inflammation, collagen deposition, and fibrosis score were determined with Hematoxylin-Eosin (HxE) and Masson's trichrome staining. Transforming growth factor-beta 1 (TGF-β1) and inducible nitric oxide synthase (iNOS) expressions were detected immunohistochemically. BLM administration increased lipid peroxidation (MDA) and decreased superoxide dismutase (SOD) and glutathione peroxidase (GPx) activity. In addition, BLM caused increased levels of tumor necrosis factor alpha (TNF-α) and interleukin-1β (IL-1β) in bronchoalveolar lavage fluid (BALF) and accumulation of collagen bundles. Zingerone administration decreased collagen accumulation, TNF-α and IL-1β levels, MDA level, TGF-β1, and iNOS expression and increased SOD and GPx activity. Histopathological findings supported the results. These results show that zingerone (50 and 100 mg/kg) at both doses significantly contributes to healing of PF by improving inflammation, oxidative stress, and histopathological alterations and by affecting TGF-β1 and iNOS signaling pathways.

Abstract
OBJECTIVE Transforming growth factor beta 1 (TGF-β1) is implicated in osteoarthritis (OA). The purpose of this study was to explore the ability of Losartan to inhibit the inflammatory signaling pathway of TGF-β1 observed during osteoarthritic progression in the temporomandibular joint (TMJ) and knee joint using a genetic mouse model. METHODS A murine OA model displaying the heterozygous chondrodysplasia gene (cho/+), a col11a1 mutation, was used to test this hypothesis. Following a 7-month treatment period with Losartan, the synovial joints were analyzed for histopathological improvement comparing two experimental groups. Tissues were fixed in paraformaldehyde, processed to paraffin section, and stained with Safranin O and Fast Green to visualize proteoglycans and collagen proteins in cartilage. Using the Modified Mankin scoring system, the degree of staining and OA progression were evaluated. RESULTS Results show heterozygous animals receiving Losartan having diminished degeneration of TMJ condylar and knee joint articular cartilage. This was confirmed in the TMJ and knee by a statistically significant decrease in the Mankin histopathology score. Decreased expression of HtrA1, a key regulator to the TGF-β1 signaling pathway, was demonstrated in vitro as well as in vivo, via Losartan inhibition. CONCLUSION Using a genetic mouse model of OA, this study demonstrated the utility of Losartan to improve treatment of human OA in the TMJ and knee joint through inhibition of the TGF-β1 signaling cascade. We further demonstrated inhibition of HtrA1, the lowering of Mankin scores to wild type control levels, and the limiting of OA progressive damage with treatment of Losartan.

Abstract
Peroxisome proliferator-activated receptor coactivator-1 alpha (PGC-1α) is a transcriptional coactivator that regulates energy metabolism and mitochondrial biogenesis. Recently, mitochondrial dysfunction has been indicated as an established risk factor for the development of renal fibrosis. However, whether PGC-1α is involved in the pathogenesis of renal fibrosis is unknown. In this study, we treated NRK-49F (normal rat kidney fibroblast) cells with transforming growth factor-beta 1 (TGF-β1) for 24 h to establish an in vitro fibrosis model. TGF-β1 induced the upregulation of type I collagen, fibronectin, TGF-β receptor I (TGFβ-RI), TGFβ-RII, Smad4, and pSmad2/3, as well as PGC-1α. NRK-49F cells transfected with pcDNA-PGC-1α showed significantly increased expression of fibronectin and type I collagen, as revealed by western blot assay. Interestingly, transfection with PGC-1α-siRNA caused a stark reversal of TGF-β1-induced cellular fibrosis, with concomitant suppression of fibronectin and type I collagen, as revealed by western blot and immunofluorescence assays. Moreover, SB431542 (TGFβ-RI), LY294002 (PI3K/Akt), and SB203580 (p38 MAPK), inhibitors of TGF-β-associated pathways, markedly suppressed TGF-β1-induced PGC-1α upregulation. These results implicate a role of PGC-1α in renal interstitial fibrosis mediated via the TGFβ-RI, PI3K/Akt, and p38 MAPK pathways. Our findings that PGC-1α-siRNA downregulates fibronectin and type I collagen suggest that it can be used as a novel molecular treatment for renal fibrosis.

Abstract
Epithelial-to-mesenchymal transition (EMT), an important cellular process, occurs during cancer development and progression, has a crucial role in metastasis by enhancing the motility of tumor cells. Dioscin is a polyphenolic component isolated from Phyllanthus amarus, which exhibits a wide range of pharmacological and physiological activities, such as anti-tumor, anti-inflammatory, anti-obesity, anti-fungal, and anti-viral activities. However, the possible role of dioscin in the EMT is unclear. We investigated the suppressive effect of dioscin on the EMT. Transforming growth factor-beta 1 (TGF-β1) is known to induce EMT in a number of cancer cell types and promote lung adenocarcinoma migration and invasion. To verify the inhibitory role of dioscin in lung cancer migration and invasion, we investigated the use of dioscin as inhibitors of TGF-β1-induced EMT in A549 lung cancer cells in vitro. Here, we found that dioscin prominently increased expression of the epithelial marker E-cadherin and expression of the mesenchymal marker N-cadherin and Snail during the TGF-β1-induced EMT. In addition, dioscin inhibited the TGF-β1-induced increase in cell migration and invasion of A549 lung cancer cells. Also, dioscin remarkably inhibited TGF-β1-regulated activation of MMP-2/9, Smad2, and p38. Taken together, our findings provide new evidence that dioscin suppresses lung cancer migration, and invasion in vitro by inhibiting the TGF-β1-induced EMT.

Abstract
The epithelial-mesenchymal transition (EMT) is an important cellular process during which polarized epithelial cells become motile mesenchymal cells, which promote cancer metastasis. Ginger, the rhizome of Zingiber officinale, is extensively used in cooking worldwide and also as a traditional medicinal herb with antioxidant, anti-inflammatory and anticancer properties. Several pungent compounds have been identified in ginger, including zingerone, which has anticancer potential. However, the role of zingerone in EMT is unclear. We investigated the synergistic effect of zingerone and its derivative on EMT. Transforming growth factor-beta 1 (TGF-β1) induces the EMT to promote hepatocellular carcinoma metastasis, including migration and invasion. To understand the repressive role of the combination of zingerone and its derivative (ZD 2) in hepatocellular carcinoma metastasis, we investigated the potential use of each compound of ginger, such as zingerone, ZD 2 and 6-shogaol, or the mixture of zingerone and ZD 2 (ZD 2-1) as inhibitors of TGF-β1 induced EMT development in SNU182 hepatocellular carcinoma cells in vitro. We show that ZD 2-1, but not zingerone, ZD 2 and 6-shogaol significantly increased expression of the epithelial marker E-cadherin and repressed Snail upregulation and expression of the mesenchymal marker N-cadherin during initiation of the TGF-β1 induced EMT. In addition, ZD 2-1 inhibited the TGF-β1 induced increase in cell migration and invasion of SNU182 hepatocellular carcinoma cells. Furthermore, ZD 2-1 significantly inhibited TGF-β1 regulated matrix metalloproteinase-2/9 and activation of Smad2/3. We also found that ZD 2-1 inhibited nuclear translocation of NF-κB, activation of p42/44 MAPK/AP1 signaling pathway in the TGF-β1 induced EMT. Our findings provide new evidence that combined treatment with ZD 2, novel zingerone derivative, and zingerone synergistically suppresses hepatocellular carcinoma metastasis in vitro by inhibiting the TGF-β1 induced EMT.

Abstract
In the epithelial-mesenchymal transition (EMT), an important cellular process, epithelial cells become mesenchymal cells. This process is also critically involved in cancer metastasis. Sanguiin H6 is a compound derived from ellagitannin, which is found in berries. Sanguiin H6 shows various pharmacological properties, including anti-angiogenic activity. Because the possible role of sanguiin H6 in the EMT and the underlying molecular mechanisms are unclear, we investigated the effect of sanguiin H6 on the EMT. Transforming growth factor-beta 1 (TGF-β1) induces the EMT and promotes lung adenocarcinoma migration and invasion through the Smad2/3 signaling pathway. Thus, to understand the inhibitory effects of sanguiin H6 on lung cancer migration and invasion, we investigated the ability of sanguiin H6 to inhibit TGF-β1-induced EMT in the A549 cell line. We found that sanguiin H6 significantly prevented the activation of Smad2/3 signaling pathway by TGF-β1. Additionally, sanguiin H6 increased the expression of the epithelial marker E-cadherin and repressed the expression of Snail and the mesenchymal marker N-cadherin during TGF-β1-induced EMT. Moreover, sanguiin H6 regulated the expression of EMT-dependent genes induced by TGF-β1. Finally, sanguiin H6 inhibited the migration and invasion of TGF-β1-stimulated A549 cells. Taken together, our findings provide new evidence that sanguiin H6 suppresses lung cancer migration and invasion in vitro by inhibiting TGF-β1 induction of the EMT.

Taken together, our findings provide new evidence that geraniin suppresses lung cancer migration, invasion, and anoikis resistance in vitro by inhibiting the TGF-β1-induced EMT.

Abstract
BACKGROUND/AIM Fisher rat thyroid cells (FRTL-5) display increased proliferation, reduced follicularization and decreased thyroxin release with repeated sub-culturing. These changes occur earlier and more rapidly following exposure to ionizing radiation. We hypothesized that altered transforming growth factor-β1 (TGF-β1) signaling contributes to these differences. MATERIALS AND METHODS Assessments included FRTL-5 cell growth rate and quantification of TGF-β1 ligand and receptors. The levels and activity of Smads2, 3 and 4 were measured by western blotting and the ability of TGF-β1 to regulate cyclin A and plasminogen activator inhibitor type 1 (PAI-1) activity was assessed using transfection assays. RESULTS TGF-β1 production increased after radiation but returned to control levels after repeated sub-culturing. There was no difference in TGF-β1 levels between un-irradiated cells at low versus high-passage number. TGF-β1 receptors and basal levels of Smads2, 3 and 4 remained unchanged. However, there were significant changes in cell proliferation, TGF-β1-mediated Smads2 and 3 activation and in TGF-β1's ability to regulate cyclin A and PAI-1 transcription in irradiated and repeatedly sub-cultured cells (p<0.05). CONCLUSION Collectively, these results support the conclusion that alterations in the TGF-β1 pathway contribute to phenotypic changes in FRTL-5 cells as a function of passage number and radiation.

Stereospecific effects of ginsenoside 20-Rg3 inhibits TGF-β1-induced epithelial-mesenchymal transition and suppresses lung cancer migration, invasion and anoikis resistance. Toxicology 2014; 322:23-33. [PMID: 24793912 DOI: 10.1016/j.tox.2014.04.002] [Citation(s) in RCA: 86] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [What about the content of this article?

Abstract
The epithelial-mesenchymal transition (EMT) is a pivotal cellular process during which epithelial polarized cells become motile mesenchymal-appearing cells, which, in turn, promotes the metastatic potential of cancer. Ginseng is a perennial plant belonging to the genus Panax that exhibits a wide range of pharmacological and physiological activities. Ginsenosides 20-Rg3, which is the active component of ginseng, has various medical effects, such as anti-tumorigenic, anti-angiogenesis, and anti-fatiguing activities. In addition, ginsenosides 20(S)-Rg3 and 20(R)-Rg3 are epimers, and this epimerization is produced by steaming. However, the possible role of 20(S)-Rg3 and 20(R)-Rg3 in the EMT is unclear. We investigated the effect of 20(S)-Rg3 and 20(R)-Rg3 on the EMT. Transforming growth factor-beta 1 (TGF-β1) induces the EMT to promote lung adenocarcinoma migration, invasion, and anoikis resistance. To understand the repressive role of 20(S)-Rg3 and 20(R)-Rg3 in lung cancer migration, invasion, and anoikis resistance, we investigated the potential use of 20(S)-Rg3 and 20(R)-Rg3 as inhibitors of TGF-β1-induced EMT development in A549 lung cancer cells in vitro. Here, we show that 20(R)-Rg3, but not 20(S)-Rg3, markedly increased expression of the epithelial marker E-cadherin and repressed Snail upregulation and expression of the mesenchymal marker vimentin during initiation of the TGF-β1-induced EMT. 20(R)-Rg3 also inhibited the TGF-β1-induced increase in cell migration, invasion, and anoikis resistance of A549 lung cancer cells. Additionally, 20(R)-Rg3 markedly inhibited TGF-β1-regulated matrix metalloproteinase-2 and activation of Smad2 and p38 mitogen activated protein kinase. Taken together, our findings provide new evidence that 20(R)-Rg3 suppresses lung cancer migration, invasion, and anoikis resistance in vitro by inhibiting the TGF-β1-induced EMT.
