[PMID: 26494507 DOI: 10.1016/j.jep.2015.10.028] [Citation(s) in RCA: 100] [Impact Index Per Article: 11.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2015] [Revised: 10/17/2015] [Accepted: 10/17/2015] [Indexed: 06/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The antineoplastic property of Coptidis Rhizoma and berberine was correlated with its traditional use of clearing internal fire, removing damp-heat and counteracting toxic pathogens. AIM OF THE STUDY The anti-tumor effect of Coptidis Rhizoma and berberine was extensively studied since our last comprehensive review in 2009. This study aims to summarize the recent updates and give rise to perspectives of Coptidis Rhizoma and berberine as potential novel antineoplastic agents. METHODS Quality studies in recent 5 years were retrieved from PubMed, Medline and CNKI with keywords including Coptis, Coptidis Rhizoma, huanglian, berberine, tumor and cancer. Studies were focused on the pharmacological actions of Coptidis Rhizoma and berberine in cancer progression. RESULTS It was shown that Coptidis Rhizoma extract and berberine may repress tumor progression by regressing abnormal cell proliferation, arresting cell cycle and inducing cell death. Studies also highlighted the actions of Coptidis Rhizoma extract and berberine in inhibiting tumor cell invasion and angiogenesis, which in turn abolish cancer metastasis. Some studies have also been conducted to reveal the potential effect of Coptidis Rhizoma extract and berberine in regulating tumor stromal microenvironment, as well as in preventing carcinogenesis. Most of the results have been demonstrated with in vivo models, but results of high-quality clinical trials are not yet available. Unspecified cancer type and staging, fluctuated dose information and variants of targets across studies of berberine/ Coptidis Rhizoma impede their clinical use for cancer treatment. CONCLUSION Recent advances highlighted by this review may shed light on future direction of studies featuring Coptidis Rhizoma and berberine as novel antineoplastic agents, which should be repeatedly proven in future animal and clinical studies. Although more evidences on its specificity and clinical efficacy are necessary to support its clinical use, Coptidis Rhizoma and berberine are highly expected to be effective, safe and affordable treatments for cancer patients.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Scutellariae radix (Scutellaria baicalensis Georgi) and Coptidis rhizoma (Coptis chinensis Franch), known as traditional Chinese medicine (TCM), have been widely used with the effects of suppressing fever, dispelling dampness, purging fire and removing toxicosis. Owing to their unimaginable complexity, it is difficult to understand their pharmacokinetic properties in detail. The aim of this study was to develop an optimal proteomics approach to analyze the protein profiling related with ADME/Tox in rat liver treated with S. radix and C. rhizoma as well as their compatibility. MATERIALS AND METHODS Male rats were respectively administered the extracts of S. radix, C. rhizoma and their mixture for 7 days, and their liver tissue samples were prepared for the comparative proteomic analysis. The significantly differentially expressed proteins between the experimental groups and the control group were found and identified by 2-DE and MALDI-TOF-MS analyses. To validate the proteomic analysis results, glutathion peroxidase, catalase and betaine homocysteine methyl transferase were selected and confirmed by western blotting. RESULTS Seventy eight significantly differentially expressed proteins between the experimental groups and the control group were found and identified. By querying the relational databases, the identified differentially expressed proteins were summarized and classified into three groups, phase I drug metabolic enzymes, phase II drug metabolic enzymes and the rest proteins which mainly involve in energy metabolism, signal transduction and cytoskeleton. These proteins involved in ADME/Tox may be the targets for metabolic studies or markers for toxicity. CONCLUSIONS Our findings indicated S. radix and C. rhizoma as well as their compatibility can assuredly influence the expression of the proteins in rat liver. After administration, the majority of these expressions presented a downward trend, which may be closely related to the pharmacological properties of the medicine. The method in this study may open up a new road for the complementary tests for ADME/Tox properties of S. radix and C. rhizoma as well as their compatibility.

Abstract
Berberine has multiple pharmacological activities, such as anti-oxidative, anti-inflammation and anticancer activity. It reduces the proliferation and induces apoptosis in the multiple myeloma cell line, U266. Here we explored the detailed mechanism by analysing the gene expression profiles in U266 treated with or without berberine. DNMT1 andDNMT3B, encoding for a highly conserved member of the DNA methyltransferases, decreased significantly. By dissection of biochemical network database (BNDB) with Kyoto Encyclopaedia of Genes and Genomes (KEGG) annotation, the p53 signalling pathway related genes were altered. By using epigenetic chromatin modification enzymes PCR Array, gene expression microarray, RT-PCR and Bisulphite sequencing, the results show that berberine can repress the expression of DNMT1 and DNMT3B, which triggers hypomethylation of TP53 by changing the DNA methylation level and the alteration of p53 dependent signal pathway in human multiple melanoma cell U266.

Berberine inhibits Smad and non-Smad signaling cascades and enhances autophagy against pulmonary fibrosis. J Mol Med (Berl) 2015; 93:1015-31. [PMID: 25877860 DOI: 10.1007/s00109-015-1283-1] [Citation(s) in RCA: 80] [Impact Index Per Article: 8.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2014] [Revised: 02/13/2015] [Accepted: 03/31/2015] [Indexed: 01/22/2023]
Abstract
UNLABELLED Idiopathic pulmonary fibrosis (IPF) is a fibroproliferative lung disorder of unknown aetiology. Transforming growth factor-β1 (TGF-β1)-mediated Smad and non-Smad signaling cascades are considered as central players in accelerating pulmonary fibrosis. We earlier reported berberine's amelioration against TGF-β1-mediated pro-fibrotic effects in bleomycin-induced pulmonary fibrosis. The present study aimed to determine the regulatory role of berberine on abrogated Smad 2/3 and FAK-dependent PI3K/Akt-mTOR signaling cascades in bleomycin-induced pulmonary fibrosis. Male Wistar rats were subjected to single intratracheal instillation of bleomycin (2.5 U/kg) on day 0, and berberine treatments were provided in either preventive or therapeutic modes, respectively. Berberine mitigated the elevated expression of fibrotic markers, α-smooth muscle actin (α-SMA), fibronectin, collagens I and III and reversed bleomycin-induced ultrastructural alterations in the lungs. Berberine inhibited the bleomycin-induced raise in p-Smad 2/3 and enhanced Smad 7 expression. Berberine blocked the activation of FAK and PI3K/Akt against bleomycin-induced dysregulation, with subsequent raise in PTEN expression. In addition, by inhibiting p-mTOR, berberine stimulated autophagy as evidenced by increase in Beclin-1, LC3-II levels with enhanced autophagosome formation. Cumulatively, through targeted inhibition of dysregulated Smad and FAK-dependent PI3K/Akt-mTOR signaling axis, berberine attenuated the fibrotic insults of bleomycin. KEY MESSAGE Berberine inhibits Smad 2/3 activation and enhances Smad 7 in bleomycin-induced rat lungs. Bleomycin-induced activation of FAK is inhibited by berberine. Berberine inhibits bleomycin-induced activation of PI3K/Akt cascade. Berberine inhibits mTOR activation to enhance autophagy and suppresses fibrotic markers.

Abstract
The mechanisms by which Chlamydia pneumoniae infection promote vascular smooth muscle cell (VSMC) migration required in the development of atherosclerosis have not yet been fully clarified. Matrix metalloproteinases (MMPs) have important roles in VSMC migration. However, it is still unknown whether MMPs are involved in C. pneumoniae infection-induced VSMC migration. In addition, whether berberine can exert its inhibitory effects on the infection-induced VSMC migration also remains unclear. Accordingly, we investigated the effects of berberine on C. pneumoniae infection-induced VSMC migration and explored the possible mechanisms involved in this process. Herein, we found that C. pneumoniae infection could induce VSMC migration through Matrigel-coated membrane (P<0.05), which can be significantly inhibited by the broad-spectrum MMP inhibitor GM6001 (P<0.05). Our results also showed that C. pneumoniae infection upregulated both mRNA and protein expressions of MMP3 and MMP9 (P<0.05). The specific phosphoinositide 3-kinase (PI3K) inhibitor LY294002 significantly suppressed the increases in MMP3 and MMP9 protein expressions induced by C. pneumoniae infection (P<0.05). Further experiments showed that berberine significantly attenuated C. pneumoniae infection-induced VSMC migration (P<0.05). Moreover, berberine suppressed the protein expressions of MMP3 and MMP9 caused by C. pneumoniae infection in a dose-dependent manner (P<0.05). C. pneumoniae infection-induced increase in the phosphorylation level of Akt at Ser473 was inhibited by the treatment with berberine (P<0.05). Taken together, our data suggest that berberine inhibits C. pneumoniae infection-induced VSMC migration by downregulating the expressions of MMP3 and MMP9 via PI3K.

Abstract
Aside from the commonly known white rice lines, colored varieties also exist. These varieties have historically been used in Chinese medicine. Anthocyanins, a large group of natural polyphenols existing in a variety of daily fruits and vegetables, have been widely recognized as cancer chemopreventive agents. The primary objective of cancer treatment strategies has traditionally focused on preventing the occurrence of metastasis. In this research the antimetastatic mechanism of anthocyanins on the invasion/migration of human oral CAL 27 cells was performed using a transwell to quantify the migratory potential of CAL 27 cells and the results show that anthocyanins can inhibit the in vitro migration and invasion of CAL 27 cancer cells. In addition, the gelatin zymography assay indicated that anthocyanins inhibited the activity of matrix metalloproteinases-2 (MMP-2). Western blotting assay also demonstrated that anthocyanins inhibited the associated protein expression of migration/invasion of CAL 27 cell. Immunofluorescence staining proved that anthocyanins inhibited nuclear factor kappa B p65 (NF-κB p65) expressions. These results demonstrated that anthocyanins from a species of black rice (selected purple glutinous indica rice cultivated at Asia University) could suppress CAL 27 cell metastasis by reduction of MMP-2, MMP-9, and NF-κB p65 expression through the suppression of PI3K/Akt pathway and inhibition of NF-κB levels.

Abstract
Background Cancer is one of the leading causes of death worldwide. Natural products have been regarded as important sources of potential chemotherapeutic agents. In this study, we evaluated the anti-proliferative activity of Argemone gracilenta’s methanol extract and its fractions. We identified those compounds of the most active fractions that displayed anti-proliferative activity. Methods The anti-proliferative activity on different cancerous cell lines (M12.C3F6, RAW 264.7, HeLa) was evaluated in vitro using the MTT colorimetric method. Identification of the active compounds present in the fractions with the highest activity was achieved by nuclear magnetic resonance (NMR) and gas chromatography-mass spectrometry (GC-MS) analyses. Results Both argemonine and berberine alkaloids, isolated from the ethyl acetate fraction, displayed high anti-proliferative activity with IC50 values of 2.8, 2.5, 12.1, and 2.7, 2.4, 79.5 μg/mL on M12.C3F6, RAW 264.7, and HeLa cancerous cell lines, respectively. No activity was shown on the normal L-929 cell line. From the hexane fraction, a mixture of fatty acids and fatty acid esters of 16 or more carbon atoms with anti-proliferative activity was identified, showing a range of IC50 values of 16.8-24.9, 34.1-35.4, and 67.6-91.8 μg/mL on M12.C3F6, RAW 264.7, and HeLa cancerous cell lines, respectively. On the normal L-929 cell line, this mixture showed a range of IC50 values of 85.1 to 100 μg/mL. Conclusion This is the first study that relates argemonine, berberine, and a mixture of fatty acids and fatty acid esters with the anti-proliferative activity displayed by Argemone gracilenta.

Abstract
In the present study, we examined the anticancer properties of berberine in KB oral cancer cells with a specific focus on its cellular mechanism. Berberine did not affect the cell viability of the primary human normal oral keratinocytes that were used as a control. However, the viability of KB cells was found to decrease significantly in the presence of berberine in a dose-dependent manner. Furthermore, in KB cells, berberine induced the fragmentation of genomic DNA, changes in cell morphology, and nuclear condensation. In addition, caspase-3 and -7 activation, and an increase in apoptosis were observed. Berberine was also found to upregulate significantly the expression of the death receptor ligand, FasL. In turn, this upregulation triggered the activation of pro-apoptotic factors such as caspase-8, -9 and -3 and poly(ADP-ribose) polymerase (PARP). Furthermore, pro-apoptotic factors such as Bax, Bad and Apaf-1 were also significantly upregulated by berberine. Anti-apoptotic factors such as Bcl-2 and Bcl-xL were downregulated. Z-VAD-FMK, a cell-permeable pan-caspase inhibitor, suppressed the activation of caspase-3 and PARP. These results clearly indicate that berberine-induced cell death of KB oral cancer cells was mediated by both extrinsic death receptor-dependent and intrinsic mitochondrial-dependent apoptotic signaling pathways. In addition, berberine-induced upregulation of FasL was shown to be mediated by the p38 MAPK signaling pathway. We also found that berberine-induced migration suppression was mediated by downregulation of MMP-2 and MMP-9 through phosphorylation of p38 MAPK. In summary, berberine has the potential to be used as a chemotherapeutic agent, with limited side-effects, for the management of oral cancer.

Int J Med Sci 2015; 12:63-71.

Abstract
BACKGROUND Over 70% of cancer metastasis from prostate cancer develops bone metastases that are not sensitive to hormonal therapy, radiation therapy, or chemotherapy. The epithelial-to-mesenchymal transition (EMT) genetic program is implicated as a significant contributor to prostate cancer progression. As such, targeting the EMT represents an important therapeutic strategy for preventing or treating prostate cancer metastasis. Berberine is a natural alkaloid with significant antitumor activities against many types of cancer cells. In this study, we investigated the molecular mechanism by which berberine represses the metastatic potential of prostate cancer. METHODS The effects of berberine on cell migration and invasion were determined by transwell migration assay and Matrigel invasion assay. Expressions of EMT-related genes were determined by an EMT PCR Array and a quantitative RT-PCR. The prognostic relevance of berberine's modulation of EMT-related genes in prostate cancer was evaluated using Kaplan-Meier survival analysis. RESULTS Berberine exerted inhibitory effects on the migratory and invasive abilities of highly metastatic prostate cancer cells. These inhibitory effects of berberine resulted in significant repression of a panel of mesenchymal genes that regulate the developmental EMT. Among EMT-related genes downregulated by berberine, high BMP7, NODAL and Snail gene expressions of metastatic prostate cancer tissues were associated with shorter survival of prostate cancer patients and provide potential therapeutic interventions. CONCLUSIONS We concluded that berberine should be developed as a pharmacological agent for use in combination with other anticancer drug for treating metastatic prostate cancer.

Berberine exposure triggers developmental effects on planarian regeneration. Sci Rep 2014; 4:4914.

Abstract
The mechanisms of action underlying the pharmacological properties of the natural alkaloid berberine still need investigation. Planarian regeneration is instrumental in deciphering developmental responses following drug exposure. Here we report the effects of berberine on regeneration in the planarian Dugesia japonica. Our findings demonstrate that this compound perturbs the regenerative pattern. By real-time PCR screening for the effects of berberine exposure on gene expression, we identified alterations in the transcriptional profile of genes representative of different tissues, as well as of genes involved in extracellular matrix (ECM) remodeling. Although berberine does not influence cell proliferation/apoptosis, our experiments prove that this compound causes abnormal regeneration of the planarian visual system. Potential berberine-induced cytotoxic effects were noticed in the intestine. Although we were unable to detect abnormalities in other structures, our findings, sustained by RNAi-based investigations, support the possibility that berberine effects are critically linked to anomalous ECM remodeling in treated planarians.

Studies on the molecular aspects of alkaloid-RNA complexation are of prime importance for the development of rational RNA targeted drug design strategies. Towards this goal, the binding aspects of three novel 9-O-N-aryl/arylalkyl amino carbonyl methyl substituted berberine analogs to four single stranded ribonucleotides, poly(G), poly(I), poly(C) and poly(U), were studied for the first time employing multifaceted biophysical tools. Absorbance and fluorescence studies revealed that these analogs bound non-cooperatively to poly(G) and poly(I) with binding affinities remarkably higher than berberine. The binding of these analogs to poly(U) and poly(C) was weaker in comparison to poly(G) and poly(I) but were one order higher in comparison to berberine. Quantum efficiency values revealed that energy transfer occurred from the RNA bases to the analogs upon complexation. The binding was dominated by large positive entropic contributions and small but favorable enthalpic contributions. Salt dependent studies established that the binding was dominated by hydrophobic forces that contributed around 90% of the total standard molar Gibbs energy. The chain length of the substitution at the 9-position was found to be critical in modulating the binding affinities. These results provide new insights into the binding efficacy of these novel berberine analogs to single stranded RNA sequences.

The roles of endoplasmic reticulum stress and mitochondrial apoptotic signaling pathway in quercetin-mediated cell death of human prostate cancer PC-3 cells. ENVIRONMENTAL TOXICOLOGY 2014; 29:428-439. [PMID: 22431435 DOI: 10.1002/tox.21769] [Citation(s) in RCA: 57] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2011] [Revised: 01/29/2012] [Accepted: 02/01/2012] [Indexed: 05/31/2023]
Abstract
Prostate cancer has its highest incidence and is becoming a major concern. Many studies have shown that traditional Chinese medicine exhibited antitumor responses. Quercetin, a natural polyphenolic compound, has been shown to induce apoptosis in many human cancer cell lines. Although numerous evidences show multiple possible signaling pathways of quercetin in apoptosis, there is no report to address the role of endoplasmic reticulum (ER) stress in quercetin-induced apoptosis in PC-3 cells. The purpose of this study was to investigate the effects of quercetin on the induction of the apoptotic pathway in human prostate cancer PC-3 cells. Cells were treated with quercetin for 24 and 48 h and at various doses (50-200 μM), and cell morphology and viability decreased significantly in dose-dependent manners. Flow cytometric assay indicated that quercetin at 150 μM caused G0/G1 phase arrest (31.4-49.7%) and sub-G1 phase cells (19.77%) for 36 h treatment and this effect is a time-dependent manner. Western blotting analysis indicated that quercetin induces the G0/G1 phase arrest via decreasing the levels of CDK2, cyclins E, and D proteins. Quercetin also stimulated the protein expression of ATF, GRP78, and GADD153 which is a hall marker of ER stress. Furthermore, PC-3 cells after incubation with quercetin for 48 h showed an apoptotic cell death and DNA damage which are confirmed by DAPI and Comet assays, leading to decrease the antiapoptotic Bcl-2 protein and level of ΔΨm , and increase the proapoptotic Bax protein and the activations of caspase-3, -8, and -9. Moreover, quercetin promoted the trafficking of AIF protein released from mitochondria to nuclei. These data suggest that quercetin may induce apoptosis by direct activation of caspase cascade through mitochondrial pathway and ER stress in PC-3 cells.

Abstract
Low-level laser therapy (LLLT) has been shown to be effective in promoting cell proliferation. There is speculation that the biostimulatory effect of LLLT causes undesirable enhancement of tumor growth in neoplastic diseases since malignant cells are more susceptible to proliferative stimuli. This study evaluated the effects of LLLT on proliferation, invasion, and expression of cyclin D1, E-cadherin, β-catenin, and MMP-9 in a tongue squamous carcinoma cell line (SCC25). Cells were irradiated with a diode laser (660 nm) using two energy densities (0.5 and 1.0 J/cm(2)). The proliferative potential was assessed by cell growth curves and cell cycle analysis, whereas the invasion of cells was evaluated using a Matrigel cell invasion assay. Expression of cyclin D1, E-cadherin, β-catenin, and MMP-9 was analyzed by immunofluorescence and flow cytometry and associated with the biological activities studied. LLLT induced significantly the proliferation of SCC25 cells at 1.0 J/cm(2), which was accomplished by an increase in the expression of cyclin D1 and nuclear β-catenin. At 1.0 J/cm(2), LLLT significantly reduced E-cadherin and induced MMP-9 expression, promoting SCC25 invasion. The results of this study demonstrated that LLLT exerts a stimulatory effect on proliferation and invasion of SCC25 cells, which was associated with alterations on expression of proteins studied.

Abstract
Bufalin has been shown to exhibit multiple pharmacological activities, including induction of apoptosis in many types of cancer cell lines. Osteosarcoma is a type of cancer which is difficult to treat and the purpose of this study was to investigate the effects of bufalin on the migration and invasion of human osteosarcoma U-2 OS cells. The wound healing assay and Boyden chamber transwell assay were used for examining the migration of U-2 OS cells. Western blotting and gelatin zymography assays were used for theexpression and activities of metalloproteinase (MMP)-2, MMP-7 or MMP-9 levels. Western blotting analysis also was used for measuring the levels of growth factor receptor-bound protein 2 (GRB2), son of sevenless homolog 1 (SOS1), c-Jun N-terminal kinases 1/2 (JNK1/2), extracellular signal-regulated kinase 1/2 (ERK1/2), and p38 in bufalin-treated U-2 OS cells. Bufalin inhibited the cell migration and invasion of U-2 OS cells in vitro. Moreover, bufalin reduced MMP-2 and MMP-9 enzyme activities of U-2 OS cells. Bufalin also suppressed the protein level of MMP-2 and reduced the levels of mitogen-activated protein kinases (MAPKs) such as JNK1/2 and ERK1/2 signals in U-2 OS cells. Our results suggest that signaling pathways for bufalin-inhibited migration and invasion of U-2 OS cells might be mediated through blocking MAPK signaling and resulting in the inhibition of MMP-2. Bufalin could be a useful agent to develop as a novel antitumor agent by virtue of its ability to inhibit tumor cell migration and invasion.

Abstract
Oral cancer is the fourth most common cause of death from cancer in Taiwanese men. Indirubin-3'-monoxime (I3M), a potent cyclin-dependent kinase inhibitor, has therapeutic effects in other cancer cells. In this study, we carried out in vitro assays to test cell viability, cell cycle progression, apoptosis, cell migration and invasion in this cancer type. In addition, using an oral tumorigenic animal model, we examined target gene and protein expression using real time qPCR, immunoblotting and immunohistochemical staining. Our results demonstrate that I3M has an anti-proliferative effect in both Cal-27 and HSC-3 oral cancer cell lines and that treatment of Cal-27 and HSC-3 cells with I3M results in apoptosis through the activation of cytochrome c. In addition, I3M interrupts the cell cycle in Cal-27 cells in a dose-dependent manner by arresting cells in the G2/M phase. We also found that I3M suppresses migration and invasion in Cal-27 cells by inhibiting the expression of focal adhesion kinase, urokinase-type plasminogen inhibitor, and matrix metalloproteinase 9. Moreover, we identified survivin as a target protein in I3M-treated oral cancer cells. Using an oral cancer mouse model, we demonstrate that topical application of an adhesive gel composed of I3M and poly(vinyl alcohol) (I3M/PVA) has dose-dependent anti-tumorigenic effects. Following treatment, the expression of survivin protein and mRNA was downregulated in cancerous tissues. Furthermore, plasma survivin levels were also reduced in the I3M-treated mice. These results suggest that topical application of I3M, a drug synthesized from indirubin, which is found in Qing-Dai - has therapeutic potential for treating oral cancer.

Abstract
The major factor in the morbidity and mortality of cancer patients is metastasis. There exists a relative lack of specific therapeutic approaches to control metastasis, and this is a fruitful area for investigation. A healthy diet and lifestyle not only can inhibit tumorigenesis but also can have a major impact on cancer progression and survival. Many chemicals found in edible plants are known to inhibit metastatic progression of cancer. While the mechanisms underlying antimetastatic activity of some phytochemicals are being delineated, the impact of diet, dietary components, and various phytochemicals on metastasis suppressor genes is underexplored. Epigenetic regulation of metastasis suppressor genes promises to be a potentially important mechanism by which dietary components can impact cancer metastasis since many dietary constituents are known to modulate gene expression. The review addresses this area of research as well as the current state of knowledge regarding the impact of diet, dietary components, and phytochemicals on metastasis suppressor genes.

Abstract
This study was carried out to evaluate the effect of cigarette smoke (CS) on the activity of oral peroxidase (OPO) after berberine was added to the cigarette filter. Activated carbon fiber (ACF) was chosen to load berberine as a part of the cellulose acetate (CA) filter to obtain the modified B-ACF cigarette filter. Then the effects of CS from the testing cigarettes on the activity of OPO were investigated in vitro by the 2-nitrobenzoic acid assay, and the smoke chemistry was also analyzed, especially the content of hydrogen cyanide (HCN) in the CS. The results indicated that the loss of activity of OPO in B-ACF filter cigarette group decreased by 20% and 25%, compared with those of ACF and CA filter cigarette groups, respectively. The relative residual activity of OPO in B-ACF filter group was increased with the increase of berberine in the filter compared with the CA filter group. It could be observed that the reduction in HCN might be related to the berberine in the cigarette filter, reducing the inhibition of CS on the activity of OPO.

Abstract
Prostate cancer is a common worldwide health problem in males with a poor prognosis due in part to tumor invasion and migration. The crude extract of Euphorbia formosana (CEEF) has been used for the treatment of numerous diseases, however, its effects on the migration and invasion of prostate cancer cells have yet to be examined. In the present study, we investigated the effects of CEEF on the migration and invasion of DU145 human prostate cancer cells in vitro. The wound healing assay and the Matrigel-uncoated migration assay were used to examine the migration of cancer cells. Western blotting was used to examine the levels of proteins associated with migration and invasion, and gelatin zymography was used to examine the secretion levels of matrix metalloproteinases-2 and -9 (MMP‑2/9) from DU145 cells following exposure to CEEF. The results indicated that CEEF suppressed the migration and invasion of DU145 prostate cancer cells and that these effects are exerted in a concentration- and time-dependent manner. CEEF inhibited the ERK1/2, p38, JNK, SOS1, PKC, PI3K and MMP-2/9 protein expression in DU145 cells. The results demonstrated that CEEF suppressed the migration and invasion of DU145 cells through inhibition of the mitogen-activated protein kinase (MAPK) signaling pathway resulting in the inhibition of MMP-2/9 in DU145 human prostate cancer cells.

Abstract
Cancer metastasis becomes an initial cause of cancer death in human population. In many cancers, it has been shown that the high levels of matrix metalloproteinase (MMP)-2 and/or MMP-9 are associated with the invasive phenotypes of cancer cells. In this study, we investigated the effects of cantharidin, a derivative of blister beetles which is one of the traditional Chinese medicines, on the adhesion, migration, and invasion of human bladder cancer TSGH-8301 cells. Cantharidin effectively suppressed TSGH-8301 cell adhesion, migration, and invasion in a concentration-dependent manner. Results from Western blotting, RT-PCR, and gelatin zymography assays indicated that cantharidin blocked the protein levels, gene expression (mRNA), and activities of MMP-2 and -9 in TSGH-8301 cells. Cantharidin also significantly suppressed the protein expressions of p-p38 and p-JNK1/2 in TSGH-8301 cells. Taken together, cantharidin was suggested to present antimetastatic potential via suppressing the levels of MMP-2 and MMP-9 expression that might be mediated by targeting the p38 and JNK1/2 MAPKs pathway in TSGH-8301 human bladder cancer cells.

Abstract
Berberine is one of the main alkaloids found in the Chinese herb Huang lian (Rhizoma Coptidis), which has been reported to have multiple pharmacological activities. This study aimed to analyze the molecular targets of berberine based on literature data followed by a pathway analysis using the PANTHER program. PANTHER analysis of berberine targets showed that the most classes of molecular functions include receptor binding, kinase activity, protein binding, transcription activity, DNA binding, and kinase regulator activity. Based on the biological process classification of in vitro berberine targets, those targets related to signal transduction, intracellular signalling cascade, cell surface receptor-linked signal transduction, cell motion, cell cycle control, immunity system process, and protein metabolic process are most frequently involved. In addition, berberine was found to interact with a mixture of biological pathways, such as Alzheimer's disease-presenilin and -secretase pathways, angiogenesis, apoptosis signalling pathway, FAS signalling pathway, Hungtington disease, inflammation mediated by chemokine and cytokine signalling pathways, interleukin signalling pathway, and p53 pathways. We also explored the possible mechanism of action for the anti-diabetic effect of berberine. Further studies are warranted to elucidate the mechanisms of action of berberine using systems biology approach.

Abstract
Background ERBB3 binding protein 1 (EBP1) gene transfer into human salivary adenoid cystic carcinoma cells has been shown to significantly inhibit cell proliferation and reduce tumor metastasis in mouse models. In the current study, to evaluate if EBP1 is a novel biomarker capable of identifying patients at higher risk of disease progression and recurrence, we examined the EBP1 expression profile in adenoid cystic carcinoma (ACC) patients and analyzed its clinicopathological relevance. To understand the underlying anti-metastatic mechanism, we investigated if EBP1 regulates invasion-related molecules. Methods We performed immunohistochemical analysis on 132 primary adenoid cystic carcinoma and adjacent non-cancerous tissues using commercial EBP1, MMP9, E-cadherin and ICAM-1 antibodies. Results were correlated to clinicopathological parameters, long-term survival and invasion-related molecules by statistical analysis. Cell motility and invasiveness of vector or wild-type EBP1-transfected ACC-M cell lines were evaluated using wound healing and Boyden chamber assays. MMP9, E-cadherin and ICAM-1 proteins in these cell lines were detected using western blot assay. Results The expression of EBP1 was significantly higher in non-cancerous adjacent tissues compared with corresponding cancer tissues. The intensity and percentage of cells that reacted with EBP1 antibodies were significantly higher in cases with tubular pattern than those with solid pattern (P<0.0001). We also found adenoid cystic carcinoma with local lymphatic metastasis had significantly lower EBP1 expression than ACC with no local lymphatic node metastasis (P<0.0001). Similar findings were observed in ACC with lung metastasis compared with cases with no lung metastasis (P<0.0001), in particular, in cases with perineural invasion compared with cases with no perineural invasion (P<0.0001). Furthermore, a decrease in EBP1 expression was positively associated with a reduction in overall survival of ACC patients. Of note, EBP1 inhibits migration and invasiveness of ACC cells by upregulating E-cadherin but downregulating MMP9. In clinical adenoid cystic carcinoma patients, higher EBP1 expression was positively correlated with E-cadherin levels (P<0.001) but negatively correlated with MMP9 expression (P=0.0002). Conclusions EBP1 expression is reduced in adenoid cystic carcinoma, indicating unfavorable prognosis of ACC patients. Its regulation of MMP9 and E-cadherin protein levels suggests a critical therapeutic potential.

Abstract
Berberine (BBR) is a natural alkaloid with significant antitumor activities against many types of cancer cells. In this study, we investigated the molecular mechanisms by which BBR repressed the metastatic potential of breast cancer cells. BBR was found to downregulate the enzymatic activities and expression levels of matrix metalloproteinases 2 and 9 (MMP2 and MMP9, respectively). The BBR-mediated suppression of MMP2 and MMP9 involved the inhibition of the Akt/nuclear factor kappa B (NF-κB) and activator protein-1 (AP-1) signaling pathways. Furthermore, BBR repressed the expression of the Akt protein by modulating the mRNA expression level and protein degradation of Akt. In conclusion, this study suggests that BBR can reduce the metastatic potential of highly metastatic breast cancer cells and may be a useful adjuvant therapeutic agent in the treatment of breast cancer by targeting the Akt pathway.

Abstract
Alkaloids are important chemical compounds that serve as a rich reservoir for drug discovery. Several alkaloids isolated from natural herbs exhibit antiproliferation and antimetastasis effects on various types of cancers both in vitro and in vivo. Alkaloids, such as camptothecin and vinblastine, have already been successfully developed into anticancer drugs. This paper focuses on the naturally derived alkaloids with prospective anticancer properties, such as berberine, evodiamine, matrine, piperine, sanguinarine, and tetrandrine, and summarizes the mechanisms of action of these compounds. Based on the information in the literature that is summarized in this paper, the use of alkaloids as anticancer agents is very promising, but more research and clinical trials are necessary before final recommendations on specific alkaloids can be made.

Abstract
Osthole, a natural compound, may be extracted from Cnidium monnieri and other medicinal plants. Previous studies have shown that osthole has anticancer effects in various human cancer cell lines. There is, however, no available information concerning the effects of osthole on the migration and invasion of human lung cancer cells. In the current study, we used Transwell assays to demonstrate that osthole inhibited the migration and invasion of A549 human lung cancer cells. Western blot analysis revealed that osthole reduced the levels of matrix metalloproteinase-2 (MMP-2) and matrix metallopeptidase-9 (MMP-9) in the A549 human lung cancer cells. Our findings indicate that osthole may have a novel function as an inhibitor of the metastasis of human lung cancer.

Abstract
The aim of the present study was to identify potentially useful natural compounds for the development of novel therapeutic agents to inhibit metastasis. A phytochemical investigation of Pachysandra terminalis resulted in the isolation of seven new pregnane alkaloids, terminamines A-G (1-7), and seven known alkaloids (8-14). The structures of 1-7 were elucidated by 1D- and 2D-NMR spectroscopic and mass spectrometric methods. Compounds 1-5 and 8-14 inhibited the migration of MB-MDA-231 breast cancer cells induced by the chemokine epithelial growth factor. In addition, compound 1 inhibited phosphorylation of integrin β(1), which plays an important role in MB-MDA-231 cell adhesion and metastasis.

Abstract
PURPOSE Focal adhesion kinase (FAK) and Src are protein tyrosine kinases, localized in the focal adhesions, which, upon activation interacts each other, regulate several cellular signaling pathways implicated in malignant transformation and disease progression. The present study aimed to evaluate the clinical significance of FAK and Src protein expression in mobile tongue squamous cell carcinoma (SCC). METHODS FAK and Src protein expression was assessed immunohistochemically on 48 mobile tongue SCC tissue samples and was analyzed in relation with clinicopathological characteristics, overall and disease-free patients' survival. RESULTS FAK positivity was noted in 32 (66.67 %) and Src positivity in 45 (93.75 %) out of 48 mobile tongue SCC cases. FAK and Src protein expression was significantly increased in well-differentiated tumors compared to poorly differentiated ones (p = 0.0455 and p = 0.0301, respectively). Mobile tongue SCC patients presenting elevated Src expression showed longer overall and disease-free survival (log-rank test, p = 0.0145 and p = 0.0388, respectively). In multivariate analysis, the depth of invasion proved to be an independent prognostic factor of both overall and disease-free patients' survival (Cox regression, p = 0.0313 and p = 0.0481, respectively), whereas Src expression did not remain significant. CONCLUSIONS The present study supported evidence for a potential role of FAK and Src signaling in mobile tongue SCC, rendering their small-molecule tyrosine kinase inhibitors as possible treatment strategy in tongue cancer chemoprevention.

Abstract
Berberine, a naturally occurring isoquinoline alkaloid, is present in a number of important medicinal plants. Berberine has a wide range of biochemical and pharmacological effects, including anticancer effects. In this study, we elucidated the mechanism of antiangiogenic activity of berberine using in vivo and in vitro models. In vivo antiangiogenic activity was studied using B16F-10 melanoma cells and induced capillary formation in C57BL/6 mice. Berberine, at 10 mg/kg body weight, showed significant inhibition in tumor-directed capillary formation and in various proangiogenic factors, such as vascular endothelial growth factor (VEGF), and proinflammatory mediators, such as interleukin (IL)-1β, IL-6, tumor necrosis factor alpha (TNF-α), and granulocyte macrophage colony-stimulating factor (GM-CSF), which are involved in tumor angiogenesis. At the same time, it could also increase antitumor factors, such as IL-2 and tissue-inhibitor metalloproteinase (TIMP) levels in the serum. Berberine could also inhibit endothelial motility, migration, tube formation, and vessel sprouting from rat aortic ring in vitro. Further, berberine inhibited various transcription factors involved in tumor development and angiogenesis, such as NF-ĸB, c-Fos, CREB, and ATF-2. mRNA expression levels of proangiogenic factors, such as cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and hypoxia-inducible factor (HIF), were also downregulated in tumor cells after treatment with berberine. Drastically elevated expressions of HIF and VEGF mRNA by tumor cells under hypoxic conditions were also decreased after treatment with berberine. This result clearly demonstrates that the antiangiogenic activity of berberine is mainly mediated through the inhibition of various proinflammatory and pro-angiogenic factors and the major ones are HIF, VEGF, COX-2, NO, NF-ĸB, and proinflammatory cytokines.

Abstract
Primary effusion lymphoma (PEL) is an infrequent and distinct entity among the aggressive non-Hodgkin B cell lymphomas that occurs predominantly in patients with advanced AIDS. It shows serous lymphomatous effusion in body cavities, and is resistant to conventional chemotherapy with a poor prognosis. Thus, the optimal treatment for PEL is not well defined and there is a need for novel agents. PEL has been recognized as the tumor caused by Kaposi sarcoma-associated herpes virus/human herpes virus-8 (KSHV/HHV-8), and nuclear factor (NF)-κB activation plays a critical role in the survival and growth of PEL cells. In this study, we assessed the antitumor effect of berberine, a naturally occurring isoquinoline alkaloid, on this pathway. The methylthiotetrazole assay showed that cell proliferation in the PEL cell lines was inhibited by berberine. Berberine also induced caspase-dependent apoptosis and suppressed NF-κB activity by inhibiting IκB kinase (IKK) phosphorylation, IκB phosphorylation and IκB degradation, upstream targets of the NF-κB pathway, in PEL cells. In a xenograft mouse model that showed ascites and diffuse organ invasion of PEL cells, treatment with berberine inhibited the growth and invasion of PEL cells significantly compared with untreated mice. These results show that the suppression of NF-κB is a molecular target for treating PEL, and berberine is a potential antitumor agent for PEL.

Abstract
Most of the chemotherapy treatments for bladder cancer aim to kill the cancer cells, but a high recurrence rate after medical treatments is still occurred. Bufalin from the skin and parotid venom glands of toad has been shown to induce apoptotic cell death in many types of cancer cell lines. However, there is no report addressing that bufalin induced cell death in human bladder cancer cells. The purpose of this study was investigated the mechanisms of bufalin-induced apoptosis in a human bladder cancer cell line (T24). We demonstrated the effects of bufalin on the cell growth and apoptosis in T24 cells by using DAPI/TUNEL double staining, a PI exclusion and flow cytometric analysis. The effects of bufalin on the production of reactive oxygen species (ROS), the level of mitochondrial membrane potential (ΔΨ(m)), and DNA content including sub-G1 (apoptosis) in T24 cells were also determined by flow cytometry. Western blot analysis was used to examine the expression of G(0)/G(1) phase-regulated and apoptosis-associated protein levels in bufalin-treated T24 cells. The results indicated that bufalin significantly decreased the percentage of viability, induced the G(0)/G(1) phase arrest and triggered apoptosis in T24 cells. The down-regulation of the protein levels for cyclin D, CDK4, cyclin E, CDK2, phospho-Rb, phospho-AKT and Bcl-2 with the simultaneous up-regulation of the cytochrome c, Apaf-1, AIF, caspase-3, -7 and -9 and Bax protein expressions and caspase activities were observed in T24 cells after bufalin treatment. Based on our results, bufalin induces apoptotic cell death in T24 cells through suppressing AKT activity and anti-apoptotic Bcl-2 protein as well as inducing pro-apoptotic Bax protein. The levels of caspase-3, -7 and -9 are also mediated apoptosis in bufalin-treated T24 cells. Therefore, bufalin might be used as a therapeutic agent for the treatment of human bladder cancer in the future.

Abstract
It has been shown that deguelin, one of the compounds of rotenoids from flavonoid family, induced cytotoxic effects through induction of cell cycle arrest and apoptosis in many types of human cancer cell lines, but deguelin-affected DNA damage and repair gene expression (mRNA) are not clarified yet. We investigated the effects of deguelin on DNA damage and associated gene expression in human lung cancer NCI-H460 cells in vitro. DNA damage was assayed by using the comet assay and DNA gel electrophoresis and the results indicated that NCI-H460 cells treated with 0, 50, 250 and 500 nM deguelin led to a longer DNA migration smear based on the single cell electrophoresis and DNA fragmentation occurred based on the examination of DNA gel electrophoresis. DNA damage and repair gene expression (mRNA) were evaluated by using real-time PCR assay and the results indicated that 50 and 250 nM deguelin for a 24-h exposure in NCI-H460 cells, decreased the gene levels of breast cancer 1, early onset (BRCA1), DNA-dependent serine/threonine protein kinase (DNA-PK), O6-methylguanine-DNA methyltransferase (MGMT), p53, ataxia telangiectasia mutated (ATM) and ataxia-telangiectasia and Rad3-related (ATR) mRNA expressions. Collectively, the present study showed that deguelin caused DNA damage and inhibited DNA damage and repair gene expressions, which might be due to deguelin-inhibited cell growth in vitro.

Abstract
An alternative quantification approach called ERETIC (Electronic REference To access In vivo Concentrations) utilizing electronic reference-based proton nuclear magnetic resonance (¹H NMR) spectroscopy techniques has been successfully introduced in our present study to simultaneously determine the contents of five major active protoberberine alkaloids (berberine, coptisine, jatrorrhizine, palmatine and epiberberine) in Rhizoma Coptidis, one of the most commonly used traditional Chinese medicines (TCM). The NMR experimental conditions including deuterated solvent, relaxation delay time, and ERETIC transmitter power level were optimized, and the developed method was validated in terms of precision, reproducibility, stability, accuracy, recovery, and limit of quantification (LOQ). The recoveries of the five tested alkaloids ranged between 89.94 and 97.72% for berberine, 90.87 and 100.05% for coptisine, 98.35 and 107.57% for jatrorrhizine, 95.37 and 101.26% for palmatine, and 93.18 and 98.00% for epiberberine, respectively, and LOQ was 0.1 mM for berberine. The high universality, accuracy, reproducibility, and efficiency of the ERETIC method demonstrated in this work suggest that this method could serve as a highly potential quantification alternative for quality assessment of TCM.

Abstract
Berberine, an isoquinoline alkaloid with a long history of use in Chinese medicine, has several important pharmacological effects. Several studies have revealed that berberine has neuroprotective and neuropsychiatric effects. However, there are few reports regarding the protective effect of berberine against neuronal damage following transient global cerebral ischemia. In this study, mice were subjected to 20 min of global brain ischemia and sacrificed 72 hr later. Berberine was administered for 7 days prior to ischemia and daily until sacrifice. Mice treated with berberine showed reduced matrix metalloproteinase-9 (MMP-9) activity. Berberine inhibited gelatinase activity directly in in situ zymography and reduced neuronal damage following global ischemia. Laminin expression and NeuN expression were markedly reduced in CA1 and CA2 areas after ischemia, and berberine reduced the laminin degradation and neuronal loss. In the TUNEL assay, damaged neurons were also apparent in the CA1 and CA2 areas, and berberine reduced TUNEL-positive cells. These data demonstrate that berberine, a plant alkaloid, may protect from hippocampal neuronal damage following transient global ischemia by reducing MMP-9 activity.

Abstract
OBJECTIVE Epidemiological studies have reported that tobacco use is a major etiological factor for oral cancer. Several matrix metalloproteinases (MMPs) have been shown to play important roles in the invasion and metastasis of oral squamous cell carcinomas, especially MMP-2 and MMP-9. This study examined the effects of cigarette smoke condensate (CSC) on oral cancer cells. DESIGN Two oral squamous cell carcinoma cell lines, SCC-25 (metastatic) and CAL-27 (non-metastatic), were exposed to different concentrations of CSC and examined for their collagen degrading ability and MMP production using collagen degradation assays, zymograms and Western blots. RESULTS Exposure to CSC increased the collagen degrading ability of the metastasizing cell line (SCC-25) by a mechanism involving increased MMP-2 and MMP-9 production. CONCLUSION CSC increased the collagen degrading ability of SCC-25 by increasing the MMP-2 and MMP-9 protein levels. Continued cigarette smoking in oral cancer patients may result in decreased survival rates due to enhanced metastatic potential of the cancer cells.

Abstract
The present study demonstrated the potential antimetastatic and antiinvasive effect of berberine using both in vivo mouse lung metastasis and in vitro models. Administration of berberine resulted in significant suppression of B16F-10 melanoma induced tumor nodule formation and enhanced the survival of tumor-bearing mice. Berberine treatment also decreased various biochemical parameters associated with lung metastasis. These inhibitory actions may be due to the significant suppression of several signaling molecules such as ERK1/2, NF-κB, ATF-2 and CREB involved in the transcription signaling pathways for MMP gene expression. It could also inhibit the migration and invasion of highly metastatic murine melanoma cells in a dose-dependent manner in vitro. The results clearly show that berberine could significantly inhibit experimental lung metastasis produced by intravenous injection of B16F-10 melanoma cells and this effect could be linked to the down-regulation of metastasis-related signaling molecules.

Abstract
Conventional chemotherapy fails to cure metastatic hepatoma mainly due to its high hepatotoxicity. Many plant-derived agents have been accepted to effectively inhibit hepatoma cell invasion. However, the investigation that whether effectual plant-derived agents against invasive hepatoma cells exert unexpected cytotoxicity in healthy hepatocytes has been ignored. This study demonstrated that berberine exhibited significant cytotoxicity in HepG2 cells mainly through upregulation of reactive oxygen species (ROS) production but was ineffective in normal Chang liver cells. Berberine exerted anti-invasive effect on HepG2 cells through suppression of matrix metalloproteinase-9 (MMP-9) expression. Moreover, berberine could significantly inhibit the activity of PI3K-AKT and ERK pathways. Combination treatment of ERK pathway inhibitor PD98059 or AKT pathway inhibitor LY294002 and berberine could result in a synergistic reduction on MMP-9 expression along with an inhibition of cell invasion. Enhancement of ROS production by berberine had no influence on its suppressive effects on the activity of PI3K-AKT and ERK pathways, as well as MMP-9 expression and HepG2 cell invasion. In conclusion, our results suggest that berberine may be a potential alternative against invasive hepatoma cells through PI3K-AKT and ERK pathways-dependent downregulation of MMP-9 expression. This study also provides a previously neglected insight into the investigation of plant-derived agents-based therapy against tumor invasion with the consideration of damage to healthy cells.

Abstract
In this study we tested whether the isoquinoline alkaloid berberine can inhibit the growth of influenza A. Our experiments showed strong inhibition of the growth of H1N1 influenza A strains PR/8/34 or WS/33 in RAW 264.7 macrophage-like cells, A549 human lung epithelial-derived cells and murine bone marrow derived macrophages, but not MDCK canine kidney cells. Studies of the mechanism underlying this effect suggest that berberine acts post-translationally to inhibit virus protein trafficking/maturation which in turn inhibits virus growth. Berberine was also evaluated for its ability to inhibit production of TNF-α and PGE(2) from A/PR/8/34 infected-RAW 264.7 cells. Our studies revealed strong inhibition of production of both mediators and suggest that this effect is distinct from the anti-viral effect. Finally, we asked whether berberine-containing ethanol extracts of goldenseal also inhibit the growth of influenza A and production of inflammatory mediators. We found strong effectiveness at high concentrations, although upon dilution extracts were somewhat less effective than purified berberine. Taken together, our results suggest that berberine may indeed be useful for the treatment of infections with influenza A.

Abstract
PURPOSE Gypenosides (Gyp) are the major components of Gynostemma pentaphyllum Makino. The authors investigated the effects of Gyp on cell morphology, viability, cell cycle distribution, and induction of apoptosis in human oral cancer SAS cells and the determination of murine SAS xenograft model in vivo. EXPERIMENTAL DESIGN Flow cytometry was used to quantify the percentage of viable cells; cell cycle distribution; sub-G1 phase (apoptosis); caspase-3, -8, and -9 activity; reactive oxygen species (ROS) production, intracellular Ca(2+) determination; and the level of mitochondrial membrane potential (ΔΨ(m)). Western blotting was used to examine levels of apoptosis-associated proteins, and confocal laser microscopy was used to examine the translocation of proteins in cells. RESULTS Gyp induced morphological changes, decreased the percentage of viable cells, caused G0/G1 phase arrest, and triggered apoptotic cell death in SAS cells. Cell cycle arrest induced by Gyp was associated with apoptosis. The production of ROS, increased intracellular Ca(2+) levels, and the depolarization of ΔΨ(m) were observed. Gyp increased levels of the proapoptotic protein Bax but inhibited the levels of the antiapoptotic proteins Bcl-2 and Bcl-xl. Gyp also stimulated the release of cytochrome c and Endo G. Translocation of GADD153 to the nucleus was stimulated by Gyp. Gyp in vivo attenuated the size and volume of solid tumors in a murine xenograft model of oral cancer. CONCLUSIONS Gyp-induced cell death occurs through caspase-dependent and caspase-independent apoptotic signaling pathways, and the compound reduced tumor size in a xenograft nu/nu mouse model of oral cancer.

Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC), the most common malignancy of the oral cavity, has been shown to occur via a multistep process driven by the accumulation of carcinogen-induced genetic changes. STUDY DESIGN Array-based comparative genomic hybridization (aCGH) and multiplex ligation-dependent probe amplification (MLPA) were conducted to screen human genomewide alterations on fresh tissues of the cancer area, the dysplastic transitional area, and the resection margin (normal) free of tumor; these samples were obtained from 7 OSCC patients. RESULTS The highest amplification frequencies (100%, 7/7) were detected in FAM5B, TIPARP, PIK3CA, NLGN1, FGF10, HDAC9, GRM3, DDEF1, EDNRB, CHRDL1, and HTR2C, and the highest deletion frequencies in THRAP3, CTTNBP2NL, GATAD2B, REL, CKAP2L, RHOA, EIF4E3, PDLIM5, FBXO3, NEUROD4, and ABCA5 in the OSCC. In the dysplasia, amplification (100%, 7/7) was detected in RNF36 and deletion in CKAP2L and TCF8. We could detect large differences with MLPA in the number of alterations between the cancer or dysplasia versus the normal area with P values of <.001. CONCLUSION These findings indicate that these DNA copy number changes on each chromosome in the 3 categories may be associated with OSCC tumorigenesis and/or progression.

Abstract
Kaempferol is a natural flavonoid. Previous studies have reported that kaempferol has anti-proliferation activities and induces apoptosis in many cancer cell lines. However, there are no reports on human osteosarcoma. In this study, we investigate the anti-cancer effects and molecular mechanisms of kaempferol in human osteosarcoma cells. Our results demonstrate that kaempferol significantly reduces cell viabilities of U-2 OS, HOB and 143B cells, especially U-2 OS cells in a dose-dependent manner, but exerts low cytotoxicity on human fetal osteoblast progenitor hFOB cells. Comet assay, DAPI staining and DNA gel electrophoresis confirm the effects of DNA damage and apoptosis in U-2 OS cells. Flow cytometry detects the increase of cytoplasmic Ca(2+) levels and the decrease of mitochondria membrane potential. Western blotting and fluorogenic enzymatic assay show that kaempferol treatment influences the time-dependent expression of proteins involved in the endoplasmic reticulum stress pathway and mitochondrial signaling pathway. In addition, pretreating cells with caspase inhibitors, BAPTA or calpeptin before exposure to kaempferol increases cell viabilities. The anti-cancer effects of kaempferol in vivo are evaluated in BALB/c(nu/nu) mice inoculated with U-2 OS cells, and the results indicate inhibition of tumor growth. In conclusion, kaempferol inhibits human osteosarcoma cells in vivo and in vitro.

Abstract
In cancer metastasis, secreted proteins play an important role in promoting cancer cell migration and invasion and thus also in the increase of cancer metastasis in the extracellular microenvironment. In this study, we developed a strategy that combined a simple gel-aided protein purification with iTRAQ labeling to quantify and discover the metastasis-associated proteins in the lung cancer cell secretome. Secreted proteins associated with lung cancer metastasis were produced using CL1-0 and CL1-5 cells with different metastatic abilities. Quantitative secretomics analysis identified a total of 353 proteins, 7 of which were considered to be metastasis-associated proteins. These included TIMP1, COL6A1, uPA, and AAT, all of which were higher in CL1-5, and AL1A1, PRDX1, and NID1, which were higher in CL1-0. Six of these metastasis-associated proteins were validated with Western blot analysis. In addition, pathway analysis was performed in building the interaction network between the identified metastasis-associated proteins. Further functional analysis of COL6A1 on the metastatic abilities of CL1 cells was also carried out. An RNA interference-based knock-down of COL6A1 suppressed the metastatic ability of CL1-5 cells; in contrast, a plasmid-transfected overexpression of COL6A1 increased the metastatic ability of CL1-0 cells. This study describes a simple and high throughput sample purification method that can be used for the quantitative secretomics analysis of metastasis-associated proteins.

Abstract
OBJECTIVE To evaluate the immunohistochemical expression of MMP-1, -2, -7, -9 and -26 in oral squamous cell carcinomas (SCCs) according to tumour site and histological grade of malignancy. STUDY DESIGN Fifteen cases of SCC of the lower lip and 15 cases of tongue SCC were selected and divided into low grade malignancy (n = 17) and high grade malignancy (n = 13). RESULTS Higher immunohistochemical expression of MMPs by neoplastic cells was observed in tongue SCCs, with a statistically significant difference for MMP-9 (P < 0.05). High-grade SCCs showed a higher expression of MMPs, except for MMP-2, with a statistically significant difference for MMP-7 (P < 0.05) and MMP-26 (P < 0.05). In addition, a direct association was observed between morphological scores of malignancy and MMP immunoreactivity, with the association being significant for MMP-7 and MMP-26. CONCLUSION The present results demonstrate the important role of MMPs in the development of SCCs of the lower lip and tongue.
