Abstract
To explore the anti-tumor effects of Radix Astragali on hypopharyngeal carcinoma and its mechanism. We have bioinformatically analyzed the potential targets of Radix Astragali and predicted the molecular mechanism of Radix Astragali treating of hypopharyngeal carcinoma. The binding process of the hub targets that could prolong the survival time of hypopharyngeal cancer patients with Radix Astragali was simulated by molecular docking. The results showed that 17 out of 36 hub targets could effectively improve the 5-year survival rate of hypopharyngeal cancer patients. Radix Astragali acts on hypopharyngeal carcinoma by regulating a signaling network formed by hub targets connecting multiple signaling pathways and is expected to become a drug for treating and prolonging hypopharyngeal carcinoma patients' survival time.

Abstract
Nasopharyngeal carcinoma (NPC) is a malignant tumor originating in the nasopharyngeal epithelium with a high incidence in southern China and parts of Southeast Asia. The current treatment methods are mainly radiotherapy and chemotherapy. However, they often have side effects and are not suitable for long-term exposure. Natural products have received more and more attention in cancer prevention and treatment because of their its high efficiency, low toxic side effects, and low toxicity. Natural products can serve as a viable alternative, and this study aimed to review the efficacy and mechanisms of natural products in the treatment of NPC by examining previous literature. Most natural products act by inhibiting cell proliferation, metastasis, inducing cell cycle arrest, and apoptosis. Although further research is needed to verify their effectiveness and safety, natural products can significantly improve the treatment of NPC.

Abstract
The Astragalus polysaccharide is an important bioactive component derived from the dry root of Astragalus membranaceus. This review aims to provide a comprehensive overview of the research progress on the immunomodulatory effect of Astragalus polysaccharide and provide valuable reference information. We review the immunomodulatory effect of Astragalus polysaccharide on central and peripheral immune organs, including bone marrow, thymus, lymph nodes, spleen, and mucosal tissues. Furthermore, the immunomodulatory effect of Astragalus polysaccharide on a variety of immune cells is summarized. Studies have shown that Astragalus polysaccharide can promote the activities of macrophages, natural killer cells, dendritic cells, T lymphocytes, B lymphocytes and microglia and induce the expression of a variety of cytokines and chemokines. The immunomodulatory effect of Astragalus polysaccharide makes it promising for the treatment of many diseases, including cancer, infection, type 1 diabetes, asthma, and autoimmune disease. Among them, the anticancer effect is the most prominent. In short, Astragalus polysaccharide is a valuable immunomodulatory medicine, but further high-quality studies are warranted to corroborate its clinical efficacy.

Abstract
Nasopharyngeal carcinoma (NPC) is an indicator disease in Asia due to its unique geographical and ethnic distribution. Dehydrocrenatidine (DC) is a β-carboline alkaloid abundantly present in Picrasma quassioides (D. Don) Benn, a deciduous shrub or small tree native to temperate regions of southern Asia, and β-carboline alkaloids play anti-inflammatory and antiproliferative roles in various cancers. However, the mechanism and function of DC in human NPC cells remain only partially explored. The present study aimed to examine the cytotoxicity and biochemical role of DC in human NPC cells. The MTT method, cell cycle analysis, DAPI determination, Annexin V/PI double staining, and mitochondrial membrane potential examination were performed to evaluate the effects of DC treatment on human NPC cell lines. In addition, western blotting analysis was used to explore the effect of DC on apoptosis and signaling pathways in related proteins. The analysis results confirmed that DC significantly reduced the viability of NPC cell lines in a dose- and time-dependent manner and induced apoptosis through internal and external apoptotic pathways (including cell cycle arrest, altered mitochondrial membrane potential, and activated death receptors). Western blot analysis illustrated that DC's effect on related proteins in the mitogen-activated protein kinase pathway can induce apoptosis by enhancing ERK phosphorylation and inhibiting Janus kinase (JNK) phosphorylation. Notably, DC induced apoptosis by affecting the phosphorylation of JNK and ERK, and DC and inhibitors (SP600125 and U0126) in combination restored the overexpression of p-JNK and p-ERK. To date, this is the first study to confirm the apoptosis pathway induced by DC phosphorylation of p-JNK and p-REK in human NPC. On the basis of evidence obtained from this study, DC targeting the inhibition of NPC cell lines may be a promising future strategy for NPC treatment.

Abstract
Nasopharyngeal carcinoma (NPC) is a common malignancy of the head and neck that arises from the nasopharynx epithelium and is highly invasive. Cyclin-dependent kinase inhibitor 3 (CDKN3) belongs to the dual-specificity protein phosphatase family, which plays a key role in regulating cell division. Abnormal expression of CDKN3 has been found in numerous types of cancer. In the current study, we explored the possible role of CDKN3 in cell proliferation, ability to invade, and radiosensitivity in NPC cells. We reported that CDKN3 was upregulated and p27 was downregulated in NPC tissues and is associated with a worse prognosis for patients. In addition, downregulation of CDKN3 and upregulation of p27 decreased cell proliferation, induced cell cycle arrest, increased apoptosis, decreased cell invasion, and enhanced radiosensitivity. Silencing of p27 significantly inhibited the effects of the knockdown of CDKN3. Moreover, downregulation of CDKN3 and upregulation of p27 inhibited the increase in tumor volume and weight in implanted tumors, decreased the phosphorylation of Akt, and increased the expression of cleaved caspase 3 in tumors. CDKN3 expression was also inversely correlated with p27 expression in NPC patients. Knockdown of CDKN3 increased p27 expression. Silencing of p27 markedly inhibited the effects of CDKN3 on cell proliferation, cell cycle progression, apoptosis, invasion, and radiosensitivity. These results demonstrate that upregulation of p27 is involved in the knockdown of CDKN3-induced decrease in cell proliferation, increase in cell cycle arrest and apoptosis, decrease in invasion, and increase in radiosensitivity. The results demonstrate that the CDKN3/p27 axis may be a novel target in the treatment of NPC.

Abstract
BACKGROUND Transketolase-like 1 (TKTL1) plays an important role in pentose phosphate pathway (PPP) branch, the main pathway generating nicotinamide adenine dinucleotide phosphate (NADPH) and nucleotides for DNA synthesis. TKTL1 is closely related to DNA damage and has a close relationship with incidence and progression of cancers. Cisplatin is the main chemotherapeutic drug by inducing DNA damage. Whether TKTL1 knockdown additively complements cisplatin-induced cytotoxicity in nasopharyngeal carcinoma cells, however, remains largely undefined. METHODS Lipofectamine 2000 was used to transfect si-TKTL1s with different sequences into the CNE2 and HONE1 cells. The mRNA and protein levels of TKTL1 were determined by qRT-PCR and western blot, respectively. MTT assay and flow cytometry were used to access the viability and apoptosis of CNE2 and HONE1 cells. The NADPH and ribose-5-phosphate levels in both CNE2 and HONE1 cells were determined by NADPH examination kit and HPCE analysis, respectively. The effect of TKTL1 knockdown and NADPH/ribose-5-phosphate supplement on DNA damage was assessed by using Comet assay. RESULTS TKTL1 knockdown significantly decreased TKTL1 level in CNE2 and HONE1 cells. A significant decrease in cell viability and an obvious increase in cell apoptosis rate were found in si-TKTL1+cisplatin group compared with si-TKTL1 group or si-control+cisplatin group. The levels of NADPH and ribose-5-phosphate in CNE1 and HONE1 cells were dramatically decreased in si-TKTL1 group compared with si-control group. TKTL1 knockdown additively complemented cisplatin-induced cytotoxicity, which was partly reversed by the supplements of NADPH and ribose-5-phosphate, including the increased survival rate, decreased apoptosis and DNA damage. CONCLUSIONS Knockdown of TKTL1 additively complements cisplatin-induced cytotoxicity in the nasopharyngeal carcinoma cells by inhibiting the levels of NADPH and ribose-5-phosphate, indicating that TKTL1 may be a promising target to improve the therapeutic effect combining with cisplatin for the patients with nasopharyngeal carcinoma.

Abstract
Misfolding and aggregation of the transthyretin (TTR) protein leads to certain forms of amyloidosis. Some nutraceuticals, such as flavonoids and natural polyphenols, have recently been investigated as modulators of the self-assembly process of TTR, but they generally suffer from limited bioavailability. To discover innovative and more bioavailable natural compounds able to inhibit TTR amyloid formation, a docking study was performed using the crystallographic structure of TTR. This computational strategy was projected as an ad hoc inspection of the possible relationship between binding site location and modulation of the assembly process; interactions with the as-yet-unexplored epigallocatechin gallate (EGCG) sites and with the thyroxine (T4) pocket were simultaneously analyzed. All the compounds studied seem to prefer the traditional T4 binding site, but some interesting results emerged from the screening of an in-house database, used for validating the computational protocol, and of the Herbal Ingredients Targets (HIT) catalogue available on the ZINC database.

Abstract
OBJECTIVE To review the anticancer effects of Radix astragali (RA), one of the most commonly used herbs to manage cancer in East Asia, and its constituents and to provide evidence of clinical usage through previously performed clinical studies. METHODS Preclinical and clinical studies related to the anticancer effects of RA were searched from inception to November 2013 in electronic databases. Two reviewers independently investigated 92 eligible studies, extracted all the data of studies and appraised methodological quality of clinical trials. The studies were categorized into in vitro and in vivo experimental studies and clinical studies, and analyzed by saponins, polysaccharides, and flavonoids of RA constituents, RA fraction, and whole extract. RESULTS In preclinical studies, RA was reported to have tumor growth inhibitory effects, immunomodulatory effects, and attenuating adverse effects by cytotoxic agents as well as chemopreventive effects. Saponins seemed to be the main constituents, which directly contributed to suppression of tumor growth through the activation of both intrinsic and extrinsic apoptotic pathway, modulation of intracellular signaling pathway, and inhibition of invasion and angiogenesis. Flavonoids suppressed tumor growth through the similar mechanisms with saponins. Polysaccharides showed immunomodulatory effects, contributing tumor shrinkages in animal models, despite the low cytotoxicity to cancer cells. Most of the clinical studies were performed with low evidence level of study designs because of various limitations. RA whole extracts and polysaccharides of RA were reported to improve the quality of life and ameliorate myelosuppression and other adverse events induced by cytotoxic therapies. CONCLUSION The polysaccharides, saponins, and flavonoids of RA, and the whole extract of RA have been widely reported with their anticancer effects in preclinical studies and showed a potential application as a adjunctive cancer therapeutics with the activities of immunomodulation, anti-proliferation and attenuation of adverse effects induced by cytotoxic therapy.

Abstract
Disturbances in DNA methylation are postulated to result in various central nervous system diseases including Alzheimer's disease (AD). The SH-SY5Y neuronal cell line treated with Aβ1-40 (5 μmol/L) protein is considered to be a model of AD. Hence the aim of this study was to examine the influence of Schizandrol A, a plant extract, on DNA methylation in SH-SY5Y cells exposed to Aβ1-40. Aβ1-40 were incubated with varying concentrations of Sehizandrol A to a final concentration of 1 (low), 3 (intermediate) or 9 μg/ml (high). Exposure of SH-SY5Y with Aβ1-40 reduced viability, and altered cellular morphology and mRNA expression of DNA methyltransferase (DNMT3A) and DNMT3B. Treatment with 1 or 3 μg/ml Sehizandrol A resulted in normal cell morphology as well as elevated cell number, enhanced viability, and increased mRNA expression of DNMT3A and DNMT3B compared to saline. However, an increase in Sehizandrol A to 9 μg/ml produced a fall in cell viability, as well as a decrease in mRNA DNMT3A and DNMT3B expression to control levels. Data demonstrated that Schizandrol A at 1 or 3 μg/ml improved cell morphological appearance and viability of Aβ1-40 injured SH-SY5Y cells by an enhanced DNA methylation pathway.

F-box/WD repeat-containing protein 7 (FBW7) is a member of the F-box protein family that regulates cell cycle progression and cell growth and differentiation. FBW7 also functions as a tumor suppressor. A cisplatin (CDDP)-based multidrug chemotherapy regimen is standard for nasopharyngeal carcinoma (NPC), but drug resistance is an increasing problem. Here, we evaluated the relationship between FBW7 and multidrug resistance-associated protein (MRP), and its correlation with drug resistance in NPC, and explored the mechanism underlying drug resistance to CDDP in this disease. We used cell viability assays, Western blotting, and small interfering RNA (siRNA) interference to investigate the underlying mechanism underlying CDDP resistance in a NPC cell line. The expression of FBW7 and MRP was detected by Western blotting after siRNA interference in the CDDP-resistant NPC cell line, CNE2-CDDP. The 3-(4 5-dimethyl-2-thiazolyl)-2 5-diphenyl-2-H-tetrazolium bromide (MTT) assay was used to evaluate drug sensitivity of various types of antitumor drugs, including paclitaxel (PCX), CDDP, fluorouracil (5-FU), and vincristine (VCR). We found that siRNA-mediated upregulation of FBW7 significantly increased CDDP chemosensitivity. The IC50 values of CDDP in siRNA-FBW7-CNE2-CDDP and FBW7-CNE2-CDDP-NC cells were 2.485 ± 0.155 and 4.867 ± 0.442 μmol/mL, respectively. The IC50 values of PCX, CDDP, 5-FU, and VCR were significantly decreased in siRNA-FBW7-CNE2 than in FBW7-CNE2-NC (3.46 ± 0.14 vs. 46.21 ± 6.03 μmol/mL; 3.76 ± 0.54 vs. 39.45 ± 0.96 μmol/mL; 2.14 ± 1.67 vs. 28.76 ± 1.89 μmol/mL; 4.43 ± 0.89 vs. 87.90 ± 3.45 μmol/mL, respectively). The IC50 of CDDP was significantly less in siRNA-FBW7-CNE2-CDDP than in FBW7-CNE2-CDDP-NC. The level of FBW7 expression in CNE2 cells was correlated with CDDP chemosensitivity. siRNA-mediated upregulation of FBW7 expression downregulated the expression of MRP, significantly increasing drug sensitivity in CNE2 cells.

Abstract
Astragalus, a commonly used traditional Chinese medicine, has exhibited antitumor actions in patients. In this study, in vitro and in vivo antitumor effects of astragalus and synergistic antitumor efficacy in combination with pterostilbene were investigated. Melanoma cells were treated with pterostilbene (Pt), graduated doses of astragalus injection (AI), or these in combination. Cell viability was measured using a MTT assay. Released nucleosomes and caspase activity were measured using enzyme-linked immunosorbent assay. Growth inhibition in vitro and in vivo was also assessed. Analysis of variance and t tests were used for statistical analysis. Significant reduction (p<0.05) in cellular proliferation were observed with AI and AI-Pt in a time- and concentration-dependent manner. Apoptosis and caspase-3/7 activity were significantly increased by AI and AI-Pt treatment (p<0.05). In vivo, AI inhibited melanoma tumor growth, with inhibition rates ranging from 36.5 to 62.3%, by inducing apoptosis via up-regulation Bax expression and the Bax/Bcl-2 ratio and down-regulating Bcl-2 expression. AI significantly inhibits the growth of melanoma in vitro and in vivo by inducing apoptosis. These data suggest that combined treatment of astragalus with pterostilbene enhances antitumor efficacy.

Abstract
NPC (nasopharyngeal carcinoma) is a common malignancy in southern China without defined aetiology. Recent studies have shown that TGFBR3 (transforming growth factor type III receptor, also known as betaglycan), exhibits anticancer activities. This study was to investigate the effects of TGFBR3 on NPC growth and the mechanisms for its actions. Effects of TGFBR3 overexpression on cell viability and apoptosis were measured by MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide], AO/EB (acridine orange/ethidium bromide) staining and electron microscopy in human NPC CNE-2Z cells. The expression of apoptosis-related proteins, p-Bad, Bad, XIAP (X-linked inhibitor of apoptosis), AIF (apoptosis-inducing factor), Bax and Bcl-2, was determined by Western blot or immunofluorescence analysis. Caspase 3 activity was measured by caspase 3 activity kit and [Ca2+]i (intracellular Ca2+ concentration) was detected by confocal microscopy. Transfection of TGFBR3 containing plasmid DNA at concentrations of 0.5 and 1 μg/ml reduced viability and induced apoptosis in CNE-2Z in concentration- and time-dependent manners. Forced expression of TGFBR3 up-regulated pro-apoptotic Bad and Bax protein, and down-regulated anti-apoptotic p-Bad, Bcl-2 and XIAP protein. Furthermore, transient overexpression of TGFBR3 also enhanced caspase 3 activity, increased [Ca2+]i and facilitated AIF redistribution from the mitochondria to the nucleus in CNE-2Z cells, which is independent of the caspase 3 pathway. These events were associated with TGFBR3-regulated multiple targets involved in CNE-2Z proliferation. Therefore transient overexpression of TGFBR3 may be a novel strategy for NPC prevention and therapy.

Abstract
Objective: The objective of the present study is to investigate the anti-proliferation activity of Astragalus on human hepatocellular carcinoma (HCC) cells and its mechanism. Materials and Methods: Hepatic cancer H22 bearing mice were used to study the anti-hepatocarcinoma activity of Astragalus in vivo. The growth curve and inhibitory rate of tumor growth were measured. Cell apoptosis of each group was measured by flow cytometry (FCM). Protein expression of Bax and Bcl-2 were analyzed by immunohistochemistry (IHC). The Statistical Package for Social Sciences version 13.0 (SPSS Inc, Chicago, IL) was used for standard statistical analysis including one-way ANOVA and Student's t-test. A value of P<0.05 was considered to be statistically significant. Results: Astragalus significantly inhibited the growth of H22 carcinoma, with an inhibitory rate of 17.28-52.36%. FCM and immunohistochemical assay show that the cell apoptosis rate and protein expression of Bax and Bax/Bcl-2 ratio of H22 transplanted tumor in Astragalus treated group were significantly higher than the control group (P<0.05). The protein expression of Bcl-2 was significantly lower than control (P<0.05). Conclusion: The results of the present study suggest that Astragalus has significant anti-tumor effect in vivo in inducing apoptosis of H22 tumor cells by promoting protein expression of Bax, decreasing protein expression of Bcl-2 gene, and markedly increasing the Bax/Bcl-2 ratio.

Abstract
Hedyotis Diffusa Willd (HDW), a Chinese herbal medicine, has been widely used as an adjuvant therapy against various cancers, including hepatocellular carcinoma (HCC). However, the underlying anticancer mechanisms are yet to be elucidated. In the present study, the anticancer effects of HDW were evaluated and the efficacy and safety of HDW combined with low-dose 5-fluorouracil (5-FU) were investigated. HepG2 cells were cultured in vitro and nude mouse xenografts were established in vivo. The proliferation of HepG2 cells was measured using the MTT method and flow cytometry. The mRNA and protein expression levels of cyclin-dependent kinase 2 (CDK2), cyclin E and E2F1 were examined using relative quantitative real-time PCR and western blot analysis, respectively. The results showed that water extract of HDW remarkably inhibited HepG2 cell proliferation in a dose-dependent manner via arrest of HepG2 cells at the G0/G1 phase and induction of S phase delay. This suppression was accompanied by a great decrease of E2F1 and CDK2 mRNA expression. In addition, HDW remarkably potentiated the anticancer effect of low-dose 5-FU in the absence of overt toxicity by downregulating the mRNA and protein levels of CDK2, cyclin E and E2F1. Our findings support the use of HDW as adjuvant therapy of chemotherapy and suggest that HDW may potentiate the efficiency of low-dose 5-FU in treating HCC.
