RESUMO
OBJECTIVE: To explore the molecular bases of Chinese medicine (CM) syndrome classification in chronic hepatitis B (CHB) patients in terms of DNA methylation, transcription and cytokines. METHODS: Genome-wide DNA methylation and 48 serum cytokines were detected in CHB patients (DNA methylation: 15 cases; serum cytokines: 62 cases) with different CM syndromes, including dampness and heat of Gan (Liver) and gallbladder (CHB1, DNA methylation: 5 cases, serum cytokines: 15 cases), Gan stagnation and Pi (Spleen) deficiency (CHB2, DNA methylation: 5 cases, serum cytokines: 15 cases), Gan and Shen (Kidney) yin deficiency (CHB3, DNA methylation: 5 cases, serum cytokines: 16 cases), CHB with hidden symptoms (HS, serum cytokines:16 cases) and healthy controls (DNA methylation: 6 cases). DNA methylation of a critical gene was further validated and its mRNA expression was detected on enlarged samples. Genome-wide DNA methylation was detected using Human Methylation 450K Assay and furthered verified using pyrosequencing. Cytokines and mRNA expression of gene were evaluated using multiplex biometric enzyme-linked immunosorbent assay (ELISA)-based immunoassay and reverse transcription-quantitative polymerase chain reaction (RT-qPCR), respectively. RESULTS: Totally 28,667 loci, covering 18,403 genes were differently methylated among CHB1, CHB2 and CHB3 (P<0.05 and |Δß value| > 0.17). Further validation showed that compared with HS, the hg19 CHR6: 29691140 and its closely surrounded 2 CpG loci were demethylated and its mRNA expressions were significantly up-regulated in CHB1 (P<0.05). However, they remained unaltered in CHB2 (P>0.05). Levels of Interleukin (IL)-12 were higher in CHB3 and HS than that in CHB1 and CHB2 groups (P<0.05). Levels of macrophage inflammatory protein (MIP)-1α and MIP-1ß were higher in CHB3 than other groups and leukemia inhibitory factor level was higher in CHB1 and HS than CHB2 and CHB3 groups (P<0.05). IL-12, MIP-1α and MIP-1ß concentrations were positively correlated with human leukocyte antigen F (HLA-F) mRNA expression (R2=0.238, P<0.05; R2=0.224, P<0.05; R=0.447, P<0.01; respectively). Furthermore, combination of HLA-F mRNA and differential cytokines greatly improved the differentiating accuracy among CHB1, CHB2 and HS. CONCLUSIONS: Demethylation of CpG loci in 5' UTR of HLA-F may up-regulate its mRNA expression and HLA-F expression was associated with IL-12, MIP-1α and MIP-1ß levels, indicating that HLA-F and the differential cytokines might jointly involve in the classification of CM syndromes in CHB.

CONTEXT: Xiaoyaosan decoction (XYS), a classical Traditional Chinese Medicine (TCM) formula is used to treat liver fibrosis in clinics. OBJECTIVE: This study explores defined compound combinations from XYS decoction to treat liver fibrosis. MATERIALS AND METHODS: Network pharmacology combined with transcriptomics analysis was used to analyze the XYS decoction and liver depression and spleen deficiency syndrome liver fibrosis. From the constructed XYS-Syndrome-liver fibrosis network, the top 10 active formulas were developed by topological analysis according to network stability. The most active formula was determined by in vitro study. The anti-fibrosis effect was evaluated by in vitro and in vivo studies. RESULTS: According to the network XYS-Syndrome-liver fibrosis network, 8 key compounds and 255 combinations were predicted from in XYS. Luteolin, licochalcone A, aloe-emodin and acacetin formula (LLAAF) had a synergistic effect on the proliferation inhibition of hepatic stellate cells compared to individual compounds alone. The treatment of XYS and LLAAF showed a similar anti-liver fibrotic effect that reduced histopathological changes of liver fibrosis, Hyp content and levels of α-SMA and collagen I in CCl4-induced liver fibrosis in rats. Transcriptomics analysis revealed LLAAF regulated PI3K-Akt, AMPK, FoxO, Jak-STAT3, P53, cell cycle, focal adhesion, and PPAR signalling. Furthermore, LLAAF was confirmed to regulate Jak-STAT and PI3K-Akt-FoxO signalling in vitro and in vivo. CONCLUSIONS: This study developed a novel anti-liver formula LLAAF from XYS, and demonstrated its anti-liver fibrotic activity which may be involved in the regulation of Jak-STAT and PI3K-Akt-FoxO signalling.

ETHNOPHARMACOLOGICAL RELEVANCE: Liver fibrosis is an outcome of many chronic liver diseases and often results in cirrhosis, liver failure, and even hepatocarcinoma. Xiaoyaosan decoction (XYS) as a classical Traditional Chinese Medicine (TCM) formula is used to liver fibrosis in clinical practice while its mechanism is unclear. AIM OF THE STUDY: The aim of this study was to investigate the anti-fibrosis effect of XYS and to explore the molecular mechanisms by combining network pharmacology and transcriptomic technologies. MATERIALS AND METHODS: The carbon tetrachloride (CCl4)-induced liver fibrosis rat were treated with three doses of XYS. The liver fibrosis and function were evaluated by histopathological examination and serum biochemical detection. The fibrosis related protein a-SMA and collagen I were assessed by Western blot. Different expressed genes (DEGs) between XYS-treated group and model group were analyzed. The herb-component-target network was constructed combined the network pharmacology. The predict targets and pathways were validated by in vitro and in vivo experiments. RESULTS: With XYS treatment, the liver function was significantly improved, and fibrotic changes were alleviated. The a-SMA and collagen I expression levels in the liver were also decreased in XYS-treated rats compared with CCl4 model rats. 108 active components and 42 targets from 8 herbs constituted herb-compound-target network by transcriptomics and network pharmacology analysis. The KEGG pathway and GO enrichment analyses showed that the FoxO, TGFß, AMPK, MAPK, PPAR, and hepatitis B and C pathways were involved in the anti-fibrosis effects of XYS. In the liver tissues, p-FoxO3a and p-Akt expression levels were significantly increased in the CCl4 model group but decreased in the XYS-treated group. The TGFß1/Smad pathway and Akt/FoxO3 pathway were verified in LX2 cells by inhibiting phosphorylation of Smad3 and Akt activity, respectively. CONCLUSIONS: Our findings suggested that XYS markedly alleviated CCl4-induced liver fibrosis in histopathological and serum liver function analyses, and this effect may occur via the TGFß1/Smad and Akt/FoxO signaling pathways.

CONTEXT: Yinhuapinggan granule (YHPG) is frequently used for treating fever, cough, and viral pneumonia in traditional Chinese medicine. OBJECTIVE: This study investigated the antiviral effects of YHPG in H1N1 influenza virus (IFV)-infected mice and its possible mechanism. MATERIALS AND METHODS: ICR mice were intranasally infected with 10 LD50 viral dose of IFV and then oral administration of YHPG (6, 12, and 18 g/kg) or oseltamivir (positive control) once a day for 2 or 4 consecutive days, six mice in each group. The lung, spleen and thymus indexes of IFV-infected mice, the expression of viral loads and pathological changes in lung tissues were performed to evaluate the antiviral effects of YHPG. Real-time PCR, immunohistochemistry and western blot assays were used to determine the expression of Bax, Bcl-2 and caspase-3. RESULTS: LD50 in mice was 10-3.5/0.02 mL. YHPG (6, 12, and 18 g/kg) dose-dependently decreased the lung index and viral load; the inhibition ratio of lung index was 5.31, 18.22, and 34.06%, respectively. Further detection revealed that YHPG (12 and 18 g/kg) significantly attenuated lung pathological changes, and increased the spleen and thymus indexes. Moreover, YHPG significantly down-regulated the mRNA and protein expression of Bax and caspase-3 in lung tissues of mice infected with IFV, and up-regulated the expression of Bcl-2. CONCLUSIONS: YHPG has significant antiviral effects in IFV-infected mice, partially by inhibiting influenza virus replication and regulating the occurrence of apoptosis induced by influenza virus infection, suggesting that YHPG may be a promising antiviral agent with potential clinical application prospects.

This paper aimed to investigate the effect of Yinhua Pinggan granule and San-ao decoction on the immunologic mechanisms of influenza viral pneumonia mice in vivo, in order to study the activity of the combined administration of different formulas on influenza A/H1N1 virus. The model of pneumonia was established in mice through nasal dropping influenza virus, and then divided randomly into five groups: normal control group, influenza virus model group, oseltamivir control group, Yinhua Pinggan granule group, and San-ao decoction group. The animals were put to death at the 5th day after gavage administration with the corresponding drugs. The contents in mice serum of TNF-α, IL-6 and IFN-γ were respectively measured by ELISA. The mRNA expressions of TLR3/7, MyD88, JNK, p38MAPK and NF-κB p65 in lung tissues were respectively detected by RT-PCR. The protein expressions of JNK, p38MAPK and NF-κB p65 in lung tissues were determined by immunohistochemical analysis, respectively. According to the results, Yinhua Pinggan granule and San-ao decoction could significantly decrease the levels of TNF-α and IL-6, increase the level of IFN-γ in mice serum of lung tissues, significantly reduce the gene expressions of TLR3/7, MyD88, JNK, p38MAPK and NF-κB p65 in influenza virus-infected mice lung tissues, and significantly reduce the protein expressions of JNK, p38MAPK and NF-κB p65 in lung tissues. Furthermore, the regulatory effect of Yinhua Pinggan granule was superior to that of San-ao decoction. In conclusion, Yinhua Pingan granule and San-ao decoction have the therapeutic effect on pneumonia mice infected by H1N1 virus in vivo. The anti-influenza mechanisms of Yinhua Pinggan granule and San-ao decoction may be the results of interactions by regulating the immunologic function of influenza virus-infected mice and TLR3/7 signaling pathway with multiple links of the gene and protein expressions. Moreover, the combined administration of warm-natured and cold-natured Yinhua Pinggan granule with the effects of detoxification and exhalation has a better effect than the single administration of warm-natured San-ao decoction.

Yinhuapinggan granule (YHPG), a modified prescription based on Ma-Huang-Tang (MHT), is used in traditional Chinese medicine (TCM) to treat influenza, cough, and viral pneumonia. In this study, we investigated the antiviral effects of YHPG by means of pre-, post-, and co-treatment, and its underlying mechanisms on regulating the levels of inflammatory-related cytokines, modulating the mRNA expressions of interferon-stimulated genes in influenza virus-infected murine macrophage cells (RAW264.7), and evaluating the protein expressions of key effectors in the Type I IFN and pattern recognition receptor (PRRs) signaling pathways. The results showed that YHPG markedly inhibited influenza virus (IFV) replication in pre-, post- and co-treatment assay, especially in post-treatment assay. Antiviral mechanisms studies revealed that YHPG (500 and 250 µg/mL) significantly up-regulated levels of IFN-ß, IFN-stimulated genes (Mx-1, ISG-15 and ISG-56) compared with the IFV control group, while the levels of IL-6 and TNF-α were significantly down-regulated. Furthermore, western blot analysis results revealed that the protein expressions of the phosphorylated forms of TBK1, IRF3, ERK1/2, P38 MAPK and NF-κB p65 were significantly down-regulated in RAW264.7 cells with the YHPG (500 and 250 µg/mL) treatment, while the expression of the phosphorylated form of STAT1 was significantly enhanced. Based on these results, YHPG had antiviral effects in IFV-infected RAW264.7 cells, which might be associated with regulation of the inflammatory cytokines production, evaluation of the levels of IFN-stimulated genes, and modulation of the protein expressions of key effectors in the Type I IFN and PRRs signaling pathways.

Fuzheng-Huayu formula (FZHY), a Chinese herbal mixture prescription, has been proven effective in treating liver fibrosis and cirrhosis in both clinical trials and animal experiments. In this study we assessed the metabolic mechanisms of traditional Chinese medicine (TCM) syndrome-based FZHY treatment in liver cirrhosis (LC). A total of 113 participants, including 50 healthy controls and 63 LC patients, were recruited. According to the diagnosis and differentiation of the TCM syndromes, the LC patients were classified into 5 TCM syndrome groups including the liver stagnation syndrome (LSS), spleen deficiency and damp overabundance syndrome (SDDOS), damp-heat accumulation syndrome (DHAS), liver-kidney Yin deficiency syndrome (LKYDS), and blood stagnation syndrome (BSS), and administered FZHY for 6 months. FZHY treatment significantly decreased serum levels of hyaluronic acid (HA), a biochemical marker for LC, as well as TCM syndrome scores (the TCM syndrome scores were decreased in all the groups with significant decreases in the LSS and LKYDS groups). Furthermore, FZHY treatment gradually shifted the metabolic profiles of LC patients from a pathologic state to a healthy state, especially in LC patients with LSS and LKYDS. Twenty-two differently altered metabolites (DAMs) were identified, including carbohydrates, amino acids, fatty acids, etc with 9 DAMs in LSS patients, 9 in LKYDS patients, and 4 in other patients. The metabolic pathways involved in the conversion of amino acids and the body's detoxification process were regulated first, followed by the pathways involved in the body's energy supply process. In conclusion, the evaluation of the effect of TCM syndrome-based FZHY treatment show that FZHY has a better effect on LKYDS and LSS than on the other TCM syndromes, and the metabolic mechanisms might be involved in the increased detoxification function in LKYDS and the improvement of energy supply in LSS, which provides important evidence for the clinical application of TCM syndrome-based treatment.

BACKGROUND/AIM: The synergistic combinations of natural products have long been the basis of Traditional Chinese herbal Medicine formulas. In this study, we investigated the synergistic effects of a combination of berberine and evodiamine against human breast cancer MCF-7 cells in vitro and in vivo, and explored its mechanism. MATERIALS AND METHODS: Cell survival was measured using the MTT assay. Apoptosis-related proteins were observed using western blot analysis. Apoptosis was detected with flow cytometric analysis and by Hoechst 33258 staining. Tumor xenografts were used in vivo. RESULTS: Compared to berberine or evodiamine treatments alone, the combination treatment of berberine (25 µM) and evodiamine (15 µM) synergistically inhibited the proliferation of MCF-7 cells in a time-dependent manner and resulted in the G0/G1 phase accumulation of cells that exhibited increased expression levels of the CDK inhibitors p21 and p27 with a concomitant reduction in the expression levels of cell-cycle checkpoint proteins cyclin D1, cyclin E, CDK4, and CDK6. Furthermore, the combination treatment induced apoptosis that was accompanied by increased expression levels of p53 and Bax, reduced expression levels of Bcl-2, activation of caspase-7, and caspase-9, and the cleavage of PARP. The combination of berberine and evodiamine synergistically inhibited tumor growth in vivo in MCF-7 human breast cancer xenografts. CONCLUSION: Combination of berberine and evodiamine acts synergistically to suppress the proliferation of MCF-7 cells by inducing cell cycle arrest and apoptosis, illustrating the potential synergistic and combinatorial application of bioactive natural products.

ETHNOPHARMACOLOGICAL RELEVANCE: Huangqi Decoction (HQD), a classical traditional Chinese medicine (TCM) formula, is used to treating liver injury in China. The aim of the study is to investigate mechanisms of HQD against dimethylnitrosamine (DMN)-induced liver fibrosis underlying metabolic profiles of bile acids. MATERIALS AND METHODS: DMN-induced liver fibrosis rats were administrated HQD and its compounds, astragalosides (AS), glycyrrhizic acid (GA) and their combination. The anti-fibrosis effects were evaluated and targeted metabolomics by UPLC-MS was used to examine whether HQD had an influence on bile acid metabolism. The levels of mRNAs associated with bile acid metabolism were expressed by RT-PCR. Chenodeoxycholic acid (CDCA)-induced hepatic stellate cells (HSCs) proliferation and activation were examined using MTS assay and Western blot. RESULTS: Histopathological changes and serum liver function in HQD group had significant improvements (P<0.01). Concentrations of free bile acids and taurine conjugates were significantly increased in DMN group (P<0.05). HQD and its compounds restored the increased bile acids to normal levels, and HQD was more effected on parts of bile acids. Furthermore, the levels of mRNAs related bile acid synthesis and reabsorption such as CYP7A1, CYP8B1, CYP27A1, OATP2, OATP3, OATP4 and NTCP were significantly down-regulated in DMN group (P<0.05), mRNAs related excretion such as MRP3 and BESP were up-regulated (P<0.01), and CYP7A1, CYP8B1, OATP3, OATP4, NTCP and MRP3 restored to normal levels by HQD treatment. Moreover, CDCA-induced HSCs proliferation and activation were weaken by HQD (P<0.05) with down-regulated α-SMA, TGF-ß1, p-Smad2 and p-Smad3 expressions. CONCLUSIONS: HQD alleviated DMN-induced liver fibrosis with a better effect than its compounds, which may be involved in the regulation of bile acid metabolism enzyme. Moreover, HQD may inhibit CDCA-induced HSCs proliferation and activation.

Yinhuapinggan granule (YHPG), a Chinese medicine granule on the basis of Ma-Huang-Tang (Ephedra Decoction) and the clinical experience of Professor Wan Haitong, has been shown to inhibit the growth of influenza virus in vitro. The aim of this study was to investigate the protective effects of YHPG on mice with influenza viral pneumonia and its effects on regulating related inflammatory cytokines in influenza virus A-infected mice. ICR mice were inoculated intranasally with 15 LD50 viral dose of influenza virus A/PR/8/34 (H1N1) and treatments with YHPG (7.5, 15 and 30g/kg) were orally administrated daily for 5 consecutive days after challenge, respectively. The results showed that mortality rate, lung index, lung histopathological changes, IL-6 and TNF-α in serum were significantly attenuated in the treatment of YHPG (15 and 30g/kg) than those in the IFV control group, while the levels of IL-2 was significantly enhanced. Moreover, the RT-PCR results revealed that YHPG (15 and 30g/kg) significantly depressed the expressions of IL-1ß, IFN-γ and TNF-α mRNA in lung tissues. Furthermore, the immunohistochemical staining results also revealed that the expression of NF-κB p65 proteins was downregulated when treated with YHPG (15 and 30g/kg). These results showed YHPG has protective effects on IFV-infected mice, due to its ability of alleviation of lung damage, regulation of the cytokine production via inhibiting the NF-κB p65 activation, attenuation of systemic and pulmonary inflammatory responses.

BACKGROUND: Liver-gallbladder dampness-heat (LGDH) and liver kidney yin deficiency (LKYD) syndromes are Chinese medicine (CM) zhengs in chronic hepatitis B (CHB) patients. This study aims to investigate the changes in cytokines and their profiles accompanied by different biological responses in LGDH and LKYD in CHB. METHODS: During 2010-2012, a total of 138 morning fasting venous blood samples were obtained from participants in Shuguang Hospital, Shanghai University of Traditional Chinese Medicine in Shanghai, China. First, serum samples from 20 health controls (HCs) and 40 CHB patients (20 LGDH, 20 LKYD) were collected to detect the profiles of cytokines by multiplex biometric ELISA-based immunoassay. Random forest (RF) with a fivefold cross-validation was used to analyze the significant cytokines. Then the significant cytokines were validated using serum samples from an independent cohort of 60 CHB patients (30 LGDH, 30 LKYD) and 18 HCs. RESULTS: There were different profiles of cytokines in LGDH and LKYD. Twenty-three significantly differentially expressed cytokines were detected, among which three cytokines, interleukin (IL)-17, macrophage inflammatory protein (MIP)-1α, and MIP-1ß, with the largest Gini scores were identified by RF, and further evaluated for their significant changes in serum levels. A receiver-operator characteristic analysis revealed that the logistic regression panel could differentiate LGDH from LKYD (P < 0.001; AUC = 0.827). A functional pathway analysis showed that cytokine-cytokine receptor interaction, cytosolic DNA-sensing pathway, and chemokine signaling pathway overlapped between LGDH and LKYD, whereas Toll-like receptor signaling pathway, intestinal immune network for IgA production, NOD-like receptor signaling pathway, and Jak-STAT signaling pathway were only enriched in LGDH. CONCLUSIONS: There were characteristic cytokines profiles in LGDH and LKYD with different inflammatory and immune responses. IL-17, MIP-1α, and MIP-1ß might be involved in the differentiation of LGDH and LKYD in CHB.
RESUMO
Fuzheng-Huayu (FZHY) tablet was formulated based on Chinese medicine theory in treating liver fibrosis. A clinical trial has indicated that FZHY can against hepatitis B-caused liver cirrhosis (HBC), but the underlying mechanism of FZHY efficacy is unclear. Here, we report that miRNA expression levels are remarkably changed when FZHY formula was used in HBC patient's treatment as a paradigm of trials. Then, we functionally characterize the significant impact of potential kernel miRNAs by miRNA-target network analysis. Enrichment analysis show that the FZHY formula dramatically effecting the molecular regulated module in HBC. Thus, we infer that FZHY plays a critical function in HBC treatment process and directly regulated many important pathways, including but not limited to cell cycle, p53 signaling pathway, and TGF-ß signaling pathway, suggesting a new strategy for investigating the molecular mechanism of FZHY treatment.
RESUMO
To study the effect of Yinghua Pinggan granule (YHPG) against influenza A/H1N1 virus in vivo and on the immunologic function of infected mice. The intranasal influenza virus infection was adopted in ICR mouse to establish the influenza virus pneumonia model. At the 3rd and 7th day after the infection, the lung index and pathologic changes in lung tissues of mice were detected. Realtime PCR and flow cytometry were employed to observe the virus load in lung tissues and the levels of CD4+, CD8+, and CD4+/CD8+ in peripheral blood. The result showed that at the 3rd and 7th day after the infection, YHPG (15, 30 g x kg(-1)) can significant decrease in the lung index and virus load in lung tissues of mice infected with influenza virus, alleviate the pathologic changes in lung tissues, significantly increase the levels of CD4+ and CD4+/CD8+ ratio and reduce the levels of CD8+ in whole blood. This indicated that YHPG can inhibit the influenza virus replication, alleviate pulmonary damage and adjust the weak immunologic function of infected mice, with a certain therapeutic effect on mice infected by H1N1 virus in vivo.

BACKGROUND: In traditional Chinese medicine (TCM) clinical practice, ZHENG (also known as TCM syndrome) helps to understand the human homeostasis and guide individualized treatment. However, the scientific basis of ZHENG remains unclear due to limitations of current reductionist approaches. METHODS: We collected the leukocyte samples of three hepatitis B-caused cirrhosis (HBC) patients with dampness-heat accumulation syndrome (DHAS) and three HBC patients with liver depression and spleen deficiency syndrome (LDSDS) for microarray analysis. We generated Gene-Regulatory-Networks (GeneRelNet) from the differentially expressed genes (DEGs) of microarray date. Core genes were validated using anther independent cohort of 40 HBC patients (20 DHAS, 20 LDSDS) with RT-PCR. RESULTS: There were 2457 mapped genes were differentially expressed between DHAS and LDSDS (Fold change ≥ 2.0, P < 0.05). There were markedly different genes co-expression patterns in DHAS and LDSDS. Furthermore, three differential co-expression genes including purine nucleoside phosphorylase (PNP); aquaporin 7 (AQP7) and proteasome 26S subunit, non-ATPase 2 (PSMD2) were screened by GeneRelNets, and their mRNA expressions were further validated by real time RT-PCR. The results were consistent with microarray. The PNP (P = 0.007), AQP7 (P = 0.038) and PSMD2 (P = 0.009) mRNA expression is significant difference between DHAS and LDSDS using the non-parametric test. Furthermore, we constructed an mRNA panel of PNP, AQP7 and PSMD2 (PAP panel) by logistic regression model, and evaluated the PAP panel to distinguish DHAS from LDSDS by area under the receiver operating characteristic curve (AUC) analysis, which showed a higher accuracy (AUC = 0.835). Gene ontology (GO) analysis indicated that the DHAS is most likely related to system process while the functions overrepresented by LDSDS most related to the response to stimulus. CONCLUSIONS: This study suggested that there are particular transcriptional profiles, genes co-expressions patterns and functional properties of DHAS and LDSDS, and PNP, AQP7, and PSMD2 may be involved in ZHENG differentiation of DHAS and LDSDS in HBC.

In order to explore the synergistic mechanisms of combinatorial treatment using curcumin and mitomycin C (MMC) for breast cancer, MCF-7 breast cancer xenografts were conducted to observe the synergistic effect of combinatorial treatment using curcumin and MMC at various dosages. The synergistic mechanisms of combinatorial treatment using curcumin and MMC on the inhibition of tumor growth were explored by differential gene expression profile, gene ontology (GO), ingenuity pathway analysis (IPA) and Signal-Net network analysis. The expression levels of selected genes identified by cDNA microarray expression profiling were validated by quantitative RT-PCR (qRT-PCR) and Western blot analysis. Effect of combinatorial treatment on the inhibition of cell growth was observed by MTT assay. Apoptosis was detected by flow cytometric analysis and Hoechst 33258 staining. The combinatorial treatment of 100 mg/kg curcumin and 1.5 mg/kg MMC revealed synergistic inhibition on tumor growth. Among 1501 differentially expressed genes, the expression of 25 genes exhibited an obvious change and a significant difference in 27 signal pathways was observed (p<0.05). In addition, Mapk1 (ERK) and Mapk14 (MAPK p38) had more cross-interactions with other genes and revealed an increase in expression by 8.14- and 11.84-fold, respectively during the combinatorial treatment by curcumin and MMC when compared with the control. Moreover, curcumin can synergistically improve tumoricidal effect of MMC in another human breast cancer MDA-MB-231 cells. Apoptosis was significantly induced by the combinatorial treatment (p<0.05) and significantly inhibited by ERK inhibitor (PD98059) in MCF-7 cells (p<0.05). The synergistic effect of combinatorial treatment by curcumin and MMC on the induction of apoptosis in breast cancer cells may be via the ERK pathway.

Cardiomyocytes apoptosis can lead to heart failure. Conventional and alternative drugs, such as Chinese herbal remedies, have been developed to target cardiomyoblast cells apoptosis. In this study, we investigated the effects of ginsenoside Rb1 (Rb1), an active compound, which is isolated from Notoginseng and Ginseng on isoproterenol-(ISO-) induced apoptosis in rat cardiomyocytes and its mechanism in vivo and in vitro. Rb1 reduced the ISO-induced apoptosis in rat cardiomyocytes and H9c2 cells. The effect of Rb1 was significantly suppressed by H89 (inhibitor for PKA), but not by C-1 (inhibitor for PKC). Based on in-cell blot analysis, the ISO-induced PKA and PKC expressions were decreased by Rb1, which was inhibited by H89, but not by C-1. The expressions of caspase-3 and caspase-9 were decreased after treatment with both ISO and Rb1, but with no change for caspase-8. Our results indicated that Rb1 reducing ISO-induced rat cardiomyocytes apoptosis may be involved in PKA and caspase-9 pathways.
RESUMO
Herbal formulas based on the traditional Chinese medicine (TCM) syndrome (ZHENG) have been used as alternative treatments for breast cancer. However, there is a lack of the experimental animal ZHENG model for the evaluation of the herbal formulas. In this study, we have established 4T1 mouse breast cancer with Liver Fire Invading Stomach Syndrome model (4T1 LFISS mice) and investigated the effects of the herbal formula, Zuo-Jin Wan (ZJW). Our results showed that 4T1 LFISS mice have the features of LFISS including irritability, loss of appetite, yellow urine, chow, and a tail hot. Compared to untreated 4T1 LFISS mice, ZJW significantly reduced tumor weight and volume (P < 0.05), although it was weaker than Cisplatin. However, ZJW significantly increased the body weight and food intake of 4T1 LFISS mice and decreased serum ALT, AST, Cr, and BUN levels and ZHENG score (P < 0.05), while Cisplatin reduced the food intake, and body weight and increased serum ALT, AST, Cr, and BUN levels in 4T1 LFISS mice. Our study has provided a mouse breast cancer ZHENG model and showed that ZJW suppresses tumor growth and improves LFISS and kidney and liver functions in the 4T1 LFISS mice.
RESUMO
Aim. To investigate the correlation of Fuzheng-Huayu tablet (FZHY) efficacy on chronic hepatitis B caused cirrhosis (HBC) and single nucleotide polymorphisms (SNPs) of CYP1A2. Methods. After 111 cases of HBC with 69 excess, 21 deficiency-excess, and 21 deficiency ZHENGs (ZHENG, also called traditional Chinese medicine syndrome) were treated by FZHY for 6 months, clinical symptoms, Child-Pugh score, and ZHENG score were observed. Three of the SNPs in CYP1A2 gene were detected and analyzed using SNaPshot assay. Results. In ZHENG efficacy between effective and invalid groups, there was significant difference (P < 0.001). The ZHENG deficiency was significantly correlated with FZHY efficacy (P < 0.05). AA genotype of CYP1A2-G2964A was significantly different with GG genotype (P < 0.05) between CYP1A2 Genotypes and FZHY efficacy on ZHENG. More importantly, GA plus AA genotype of CYP1A2-G2964A was significantly different with deficiency ZHENG (P < 0.05) between CYP1A2 genotypes and FZHY efficacy on ZHENG. Conclusion. FZHY improved ZHENG score of HBC, and these efficacies may relate to CYP1A2-G2964A sites. It was suggested that CYP1A2-G2964A locus is probably a risk factor for ZHENG-based FZHY efficacy in HBC.
RESUMO
Cancer metastasis is refractory to most forms of chemotherapy. Conventional and alternative drugs, such as Chinese herbal remedies, have been developed to target metastatic cancer cells. In this study, we investigated the effects of PC-SPESII, an herbal formulation, on the migration, invasion, and metastasis of an experimental human breast cancer cell line in vivo and in vitro. PC-SPESII suppressed pulmonary metastasis and tumor growth of MDA-MB-231 human breast cancer xenografts without affecting body weight, liver function, and kidney function. PC-SPESII also inhibited MDA-MB-231 cell migration and invasion in vitro in a dose-dependent manner. Based on ELISA analysis, secretion of MMP-2 and MMP-9, proteins associated with extracellular matrix degradation, was reduced in response to PC-SPESII treatment. Western blot analysis of whole-cell extracts revealed that the levels of proteolytic proteins associated with matrix and base membrane degradation (MMP-2, MMP-9, and uPA) were decreased and the levels of their endogenous inhibitors (TIMP1 and TIMP2) were increased. Moreover, the p38MAPK and SAPK/JNK signaling pathway, which stimulates proteolytic enzymes and matrix degradation, was inhibited by PC-PSESII. Remarkably, cotreatment with PC-PSESII and p38MAPK or SAPK/JNK inhibitors magnified the antimetastatic phenotype. Our results indicate that PC-PSESII impairs human breast cancer metastasis by regulating proteolytic enzymes and matrix dynamics through the p38MAPK and SAPK/JNK pathway.
