Abstract
Nocardia rubra cell wall skeleton (Nr-CWS) has proven to be a successful medicine for therapy of cervical human papillomavirus infection. The mechanism of action of Nr-CWS is unclear but may involve a stimulatory effect on the host immune system. We previously found that CD4+ T cells were increased in cervical tissue after Nr-CWS treatment. Microarray data from these cervical tissues revealed the significant upregulation of formylated peptide receptor 3 (FPR3). This study aimed to explore the role of Nr-CWS in immunomodulatory based on these findings. Examination of CD4+ T cell subsets in cervical tissue from patients who received Nr-CWS revealed substantial increases in Th1 cytokines and transcription factors. The regulatory effects of Nr-CWS on the function and phenotype of dendritic cells (DCs) were assessed in comparison with the traditional DC maturation inducer lipopolysaccharide (LPS). Similar to LPS, Nr-CWS potently induced DC maturation and interleukin-12 (IL-12) secretion. Differentiation of T cells induced by Nr-CWS stimulated DCs was assessed using the mixed lymphocyte reaction assay. Significant differentiation towards Th1 was evident. Finally, FPR3 expression in DCs in response to Nr-CWS and LPS was measured. Nr-CWS potently upregulated FPR3 expression, while the LPS did not. Silencing FPR3 in DCs reduced Nr-CWS-induced IL-12 production and Th1 cell polarization in co-cultured T cells. The collective findings indicate that Nr-CWS may target FPR3 on the surface of DC cells and activate a Th1-type immune response. The findings clarify the basis of the antiviral immune effects of Nr-CWS on human papillomavirus.

Abstract
In recent decades, cancer immunotherapy has demonstrated considerable clinical advantages in cancer therapy. Particularly, the use of immunological gene therapy continues to grow in this field. Macrophage Inflammatory Protein 3 Beta (MIP-3β) has emerged as a potential immunomodulator for anti-cancer treatments by enhancing the interaction among immune responses. In this study, we demonstrate an innovative targeted gene delivery system based on a self-assembly technique with 1,2-Dioleoyl-3-trimethylammonium-propane (DOTAP), Methoxy poly(ethylene glycol)-poly(lactide) (MPEG-PLA), and folic acid modified poly(ethylene glycol)-poly(ε-caprolactone) (FA-PEG-PCL) (FDMCA). Results showed that the expression of MIP-3β was up-regulated in cancer cells following the transfection with FDMCA-pMIP-3β, in comparison with cells transfected with DMCA-pMIP-3β. The supernatants collected from cancer cells transfected with FDMCA-pMIP-3β and DMCA-pMIP-3β both instigate dendritic cell maturation, M1 polarisation of macrophages, activation and presentation of cytotoxicity in lymphocytes. Moreover, tumor growth and metastasis were markedly inhibited following the administration of the FDMCA-pMIP-3β complex in both subcutaneous and pulmonary metastasis mice models, which is attributed to reduced angiogenesis, enhanced cancer cell apoptosis, and suppressed proliferation by activation of the immune system. Our study suggests that the MIP-3β plasmid and FDMCA complex provide a new approach for the treatment of breast cancer.

Abstract
A recent neoadjuvant vaccine trial for early breast cancer induced strong Th1 immunity against the HER-2 oncodriver, complete pathologic responses in 18% of subjects, and for many individuals, dramatically reduced HER-2 expression on residual disease. To explain these observations, we investigated actions of Th1 cytokines (TNF-α and IFN-γ) on murine and human breast cancer cell lines that varied in the surface expression of HER-family receptor tyrosine kinases. Breast cancer lines were broadly sensitive to the combination of IFN-γ and TNF-α, as evidenced by lower metabolic activity, lower proliferation, and enhanced apoptosis, and in some cases a reversible inhibition of surface expression of HER proteins. Apoptosis was accompanied by caspase-3 activation. Furthermore, the pharmacologic caspase-3 activator PAC-1 mimicked both the killing effects and HER-2-suppressive activities of Th1 cytokines, while a caspase 3/7 inhibitor could prevent cytokine-induced HER-2 loss. These studies demonstrate that many in vivo effects of vaccination (apparent tumor cell death and loss of HER-2 expression) could be replicated in vitro using only the principle Th1 cytokines. These results are consistent with the notion that IFN-γ and TNF-α work in concert to mediate many biological effects of therapeutic vaccination through the induction of a caspase 3-associated cellular death mechanism.

Abstract
Human epidermal growth factor receptor-2 positive breast cancer (HER2+ BC) is characterized by a high rate of metastasis and drug resistance. The advent of targeted therapy drugs greatly improves the prognosis of HER2+ BC patients. However, drug resistance or severe side effects have limited the application of targeted therapy drugs. To achieve more effective treatment, considerable research has concentrated on strategies to overcome drug resistance. Abemaciclib (CDK4/6 inhibitor), a new antibody-drug conjugate (ADC), src homology 2 (SH2) containing tyrosine phosphatase-1 (SHP-1) and fatty acid synthase (FASN) have been demonstrated to improve drug resistance. In addition, using an effective vector to accurately deliver drugs to tumors has shown good application prospects. Many studies have also found that natural anti-cancer substances produced effective results during in vitro and in vivo anti-HER2+ BC research. This review aimed to summarize the current status of potential clinical drugs that may benefit HER2+ BC patients in the future.

Abstract
Using external methods to induce the death of cancer cells is recognized as one of the main strategies for cancer treatment. Research indicated that TNF-α is frequently used in tumor biotherapy while IFN-γ can directly inhibit tumor cell proliferation. In our study, TNF-α and IFN-γ were coimmobilized on polystyrene material (PSt) or Fe3O4-oleic acid nanoparticles (NPs). Then the structural change of these two proteins can be observed. Meanwhile, the expressions of both TNF-α and IFN-α increased significantly, as determined by gene microarray analysis; however, in the presence of TNF-α plus IFN-α inhibitors, TNF-α and IFN-α did not increase in HeLa cells induced by coimmobilized IFN-γ plus TNF-α. Our results indicate that such change can stimilate HeLa cells to secrete more TNF-α and IFN-α, by which the apoptosis of HeLa cells could be further induced. This study is the first report of autocrine-induced apoptosis of HeLa cells. In addition, we performed ELISA, RT-PCR, flow cytometry, and Western blot analyses, as well as a series of analytical tests at the animal level. our data also indicate that the PSt-coimmobilized IFN-γ plus TNF-α has apparent effects for cancer treatment in vivo, which is of great significance for translation into clinical medicine.

Abstract
A realistic control of cell cycle arrest is an attractive goal for the development of new effective anti-cancer drugs. Any clinical application of an effective anti-cancer drug necessarily relies on the understanding of cellular interaction mechanisms. In the present study, we prepared a co-immobilized TNF-α plus IFN-γ biomaterial, which showed a significant inhibition effect on cervical cancer cell growth, as demonstrated by a series of structural and cellular characterizations. We found that co-immobilized TNF-α plus IFN-α induced a long-term G1 phase cell cycle arrest in HeLa, SiHa, and CaSki cells, respectively. More surprisingly, the expression level of the p27 protein decreased, even when p27 mRNA was highly expressed. In addition, gene-chip results and microarray analysis showed that p57 may be downstream from p27, which acts as a direct regulator of the long-term G1 cell cycle arrest in these cells, leaving no escape for cervical cancer cells. Finally, we also investigated the anti-tumor mechanism of co-immobilized TNF-α plus IFN-γin vivo, using a nude mice animal model. To sum up, our findings suggested that the co-immobilized TNF-α plus IFN-γ can induce a long-term cell cycle arrest in cancer, thus serving as a very efficient tool for treating cervical cancer.

Abstract
Background: Ebenus boissieri Barbey is an Antalya, Turkey-endemic plant belonging to Fabaceae family. The aerial parts and the roots of E. boissieri Barbey were used in this study. Objective: In the present study, we have examined the apoptotic effects of hydroalcoholic extracts of E. boissieri Barbey in human cervical cancer cell line HeLa. Materials and Methods: To determine the cytotoxic effect, cells were treated with various concentrations of extracts for 24, 48, and 72 h incubation periods. Cytotoxic effects were examined by Cell Titer 96 aqueous nonradioactive cell proliferation assay and the results were corrected by live/dead viability/cytotoxicity assay and trypan blue exclusion assay. Apoptotic effects were studied with multicaspase kit. Tumor necrosis factor-alpha (TNF-α) and interferon gamma (IFN-γ) release were also measured by enzyme-linked immunosorbent assay. Results: According to the results, E. boissieri Barbey extract caused significant increase in caspase levels. Thus, we suggest that the extract induces cells to undergo apoptosis. Especially, there was a sharp induction in caspase-3 activity. Levels of both TNF-α and IFN-γ in extract-treated groups were significantly and dose dependently exalted as compared to their relative controls. Conclusion: The effects of the extract on caspase-3, TNF-α, and IFN-γ levels mediate the plausible mechanism of apoptosis induction in HeLa. To the best of our knowledge, this is the first report indicating any pharmacological properties of E. Boissieri on HeLa cells. SUMMARY HeLa cell viability was reduced in dose-dependent manner for 72 h with an IC50 of approximate 28.03 μg/mL for aerial and 41.02 μg/mL for root HeLa cells, exposure to the aerial extract led to 1.9, 3.8, 1.2, 2.4, and 3.45 fold induction of all caspases activities (-2, -3, -6, -8, and -9, respectively) Both 30 μg/mL of aerial and 45 μg/mL of root extracts allowed the production of anticancer cytokines (TNFalpha; IFNgamma) in HeLa cell culture supernatants.

Abstract
Synthesis of artificial and functional structures for bone tissue engineering has been well recognized but the associated cell senescence issue remains much less concerned so far. In this work, surface-modified polycaprolactone-polylactic acid scaffolds using self-assembled heterojunction carbon nanotubes (sh-CNTs) combined with insulin-like growth factor-1 are synthesized and a series of structural and biological characterizations are carried out, with particular attention to cell senescence mechanism. It is revealed that the modified scaffolds can up-regulate the expressions of alkaline phosphates and bone morphogenetic proteins while down-regulate the expressions of senescence-related proteins in mesenchymal stem cells, demonstrating the highly preferred anti-senescence functionality of the sh-CNTs modified scaffolds in bone tissue engineering. Furthermore, it is also found that with sh-CNTs, scaffolds can accelerate bone healing with extremely low toxicity in vivo.

Abstract
HER2-directed therapies are less effective in patients with ERpos compared to ERneg breast cancer, possibly reflecting bidirectional activation between HER2 and estrogen signaling pathways. We investigated dual blockade using anti-HER2 vaccination and anti-estrogen therapy in HER2pos/ERpos early breast cancer patients. In pre-clinical studies of HER2pos breast cancer cell lines, ERpos cells were partially resistant to CD4+ Th1 cytokine-induced metabolic suppression compared with ERneg cells. The addition of anti-estrogen treatment significantly enhanced cytokine sensitivity in ERpos, but not ERneg, cell lines. In two pooled phase-I clinical trials, patients with HER2pos early breast cancer were treated with neoadjuvant anti-HER2 dendritic cell vaccination; HER2pos/ERpos patients were treated with or without concurrent anti-estrogen therapy. The anti-HER2 Th1 immune response measured in the peripheral blood significantly increased following vaccination, but was similar across the three treatment groups (ERneg vaccination alone, ERpos vaccination alone, ERpos vaccination + anti-estrogen therapy). In the sentinel lymph nodes, however, the anti-HER2 Th1 immune response was significantly higher in ERpos patients treated with combination anti-HER2 vaccination plus anti-estrogen therapy compared to those treated with anti-HER2 vaccination alone. Similar rates of pathologic complete response (pCR) were observed in vaccinated ERneg patients and vaccinated ERpos patients treated with concurrent anti-estrogen therapy (31.4% vs. 28.6%); both were significantly higher than the pCR rate in vaccinated ERpos patients who did not receive anti-estrogen therapy (4.0%, p = 0.03). Since pCR portends long-term favorable outcomes, these results support additional clinical investigations using HER2-directed vaccines in combination with anti-estrogen treatments for ERpos/HER2pos DCIS and invasive breast cancer.

Abstract
Background: Fabaceae family members are known to possess preventive and therapeutic potentials against various types of cancers. Objective: The aim of this study was to investigate the cytotoxic and apoptotic effects of hydroalcoholic extracts from the aerial parts and roots of an endemic Ebenus species; Ebenus boissieri Barbey in human lung cancer cell line. Materials and Methods: After treatment with hydroalcoholic extracts cytotoxic activities of both extracts were measured by 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide assay, whereas caspase-3 activity, tumor necrosis factor-a lpha (TNF-α) and interferon gamma (IFN-γ) releasewere measured by enzyme linked immunosorbent assay. Results: According to in vitro assay results, the increase in all caspases activity suggested that extracts induce cells to undergo apoptosis. Especially, induction in caspase-3 activity was the most remarkable result of this study. Both aerial part and root extracts induced apoptosis by increasing caspase-3 activity, TNF-α and IFN-γ release. When compared to their relative controls, the concentrations of both TNF-α and IFN-γ in extract-treated groups were significantly and dose dependently exalted. Conclusion: Taken together, our results indicate that the hydroalcoholic extracts of E. boissieri can be considered as a source of new anti-apoptotic and therefore anti-carcinogenic agent.

Abstract
Nanoparticle drugs and relevant treatment technologies have achieved widespread attention in recent years. Hepatocellular carcinoma (HCC) remains a challenging malignancy of worldwide importance since it is one of the worst malignant tumors. In this study, magnetic Fe3O4 nanoparticles are prepared via a co-precipitation reaction with self-assembled surface monolayers of oleic acid molecules. For synthesizing the nanoparticle anti-tumor drug used against HCC, the liquid photo-immobilization method is used to bond the photoactive N-isopropylacrylamide derivative (NIPAm-AA) onto the oleic acid monolayer for subsequently embedding doxorubicin, photoactive tumor necrosis factor-α (TNF-α)/interferon-γ (IFN-γ), and folic acid (FOL). We investigate how the nanoparticle drug inhibits the growth of human hepatocellular carcinoma HepG2 cells in vitro and in vivo. Remarkably, our characterizations show that the nanoparticle drug demonstrates much higher anticancer efficacy (94.7%) in vitro than previously reported drugs. It is revealed that the programmed cell death induced by the drug is mainly oncosis, a new programmed cell death pathway, different from earlier proposed mechanisms. This oncosis mechanism is also confirmed in the other two hepatocellular carcinoma cells (BEL-7402 and Huh-7). This study may be helpful for developing a new type of nanoparticle drug capable of assuring molecular control of both the cell inner nucleus and outer membrane as a means to enormously increase the drug efficacy in human hepatocellular carcinoma.

Abstract
Nanomagnetic materials offer exciting avenues for advancing cancer therapies. Most researches have focused on efficient delivery of drugs in the body by incorporating various drug molecules onto the surface of nanomagnetic particles. The challenge is how to synthesize low toxic nanocarriers with multi-target drug loading. The cancer cell death mechanisms associated with those nanocarriers remain unclear either. Following the cell biology mechanisms, we develop a liquid photo-immobilization approach to attach doxorubicin, folic acid, tumor necrosis factor-α, and interferon-γ onto the oleic acid molecules coated Fe3O4 magnetic nanoparticles to prepare a kind of novel inner/outer controlled multi-target magnetic nanoparticle drug carrier. In this work, this approach is demonstrated by a variety of structural and biomedical characterizations, addressing the anti-cancer effects in vivo and in vitro on the HeLa, and it is highly efficient and powerful in treating cancer cells in a valuable programmed cell death mechanism for overcoming drug resistance.

Abstract
IFN-γ is a cytokine that plays crucial role in innate and adaptive immunity against viral and intracellular bacterial infections and for tumor control. IFN-γ is also a key activator of macrophages [1,2]. In the present study, we studied detailed modulation of IFN-γ on phenotypic and functional maturation of murine bone marrow derived dendritic cells (BMDCs). Phenotypic and functional maturation of BMDCs was evaluated by light microscope, flow cytometry(FCM), transmission electron microscopy (TEM), cytochemistry method, acid phosphatase activity(ACP), FITC-dextran bio-assay and enzyme linked immunosorbent assay (ELISA). We elucidated that IFN-γ up-regulated the expression of MHC II, CD40, CD80, CD83 and CD86 molecules on BMDCs, down-regulated the activity of pinocytosis and phagocytosis by BMDCs, and induced higher levels of IL-12 and TNF-α secreted by BMDCs. It is therefore confirmed that IFN-γ can effectively promote the maturation of BMDCs. Our study provides more evidence and rationale on future application of IFN-γ for enhancing host immunity.

ADAM17 silencing in mouse colon carcinoma cells: the effect on tumoricidal cytokines and angiogenesis. PLoS One 2012; 7:e50791.

Abstract
ADAM17 (a disintegrin and metalloprotease 17) is a major sheddase for numerous growth factors, cytokines, receptors, and cell adhesion molecules and is often overexpressed in malignant cells. It is generally accepted that ADAM17 promotes tumor development via activating growth factors from the EGF family, thus facilitating autocrine stimulation of tumor cell proliferation and migration. Here we show, using MC38CEA murine colon carcinoma model, that ADAM17 also regulates tumor angiogenesis and cytokine profile. When ADAM17 was silenced in MC38CEA cells, in vivo tumor growth and in vitro cell motility were significantly diminished, but no effect was seen on in vitro cell proliferation. ADAM17-silencing was accompanied by decreased in vitro expression of vascular endothelial growth factor-A and matrix metalloprotease-9, which was consistent with the limited angiogenesis and slower growth seen in ADAM17-silenced tumors. Among the growth factors susceptible to shedding by ADAM17, neuregulin-1 was the only candidate to mediate the effects of ADAM17 on MC38CEA motility and tumor angiogenesis. Concentrations of TNF and IFNγ, cytokines that synergistically induced proapoptotic effects on MC38CEA cells, were significantly elevated in the lysates of ADAM17-silenced tumors compared to mock transfected controls, suggesting a possible role for ADAM17 in host immune suppression. These results introduce new, complex roles of ADAM17 in tumor progression, including its impact on the anti-tumor immune response.

Abstract
BACKGROUND Pancreatic cancer has poor prognosis and high mortality. Currently, the therapy of pancreatic cancer remains a challenge. In this study, we compared the antitumor activity of the recombinant antitumor antiviral protein (RAAP), an improved interferon, with gemcitabine, a classic chemotherapy agent used for pancreatic cancer treatment. METHODS The proliferation of Bx-PC3 pancreatic cancer cells was evaluated by an MTT assay. Cell cycle arrest and apoptosis were evaluated by flow cytometry and annexin V-FITC/propidium iodide double staining, respectively. The expressions of matrix metalloproteinase (MMP)-2, MMP-9, caspase-3, caspase-8, and caspase-9 genes were evaluated by reverse transcription-polymerase chain reaction and the Western blot analysis. A xenograft pancreatic cancer model was established by inoculating Bx-PC3 cells into athymic nude mice. The antitumor activity of RAAP and gemcitabine was tested in the xenograft tumor model. RESULTS RAAP significantly inhibited proliferation, induced cell cycle arrest, and induced apoptosis in Bx-PC3 cells in vitro and delayed tumor growth in vivo. The antitumor activity of 20 ng/mL of RAAP was a little more effective than 10 μM of gemcitabine. The antitumor activity of RAAP was associated with its role in inducing caspase-3 and caspase-8 expression as well as downregulating MMP-2 expression. CONCLUSIONS RAAP can effectively suppress human pancreatic cancer cell growth in vitro and in vivo. The antitumor efficacy of RAAP is similar to gemcitabine.

Abstract
The aim of this study is to reveal the biological mechanism for high anti-cancer efficiency of co-immobilized TNF-α plus IFN-γ polymeric drug (co-immobilized drug) in mediating two gynecologic cancer cell lines: MCF-7 and OVCAR-3. The co-immobilized drug is prepared by mixing 10 ng/ml TNF-α plus 10 ng/ml IFN-γ which are then photo-immobilized onto cell culture polystyrene plates. The drug compositions and microstructures are characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. The MCF-7 and OVCAR-3 cell cycle arrest and programmed cell death are checked by flow cytometry, and the expression of p53 is probed by immunofluorescence staining. The phosphorylation sites of the p53 regulation and the apoptosis key protein expressions of caspase 3, 8 and 9 are detected by western blot assay. Our data show that, in case of short treatment time (48 h) at low cytokine concentrations (20 ng/ml), the co-immobilized drug demonstrates visible effects in comparison with the treatment using TNF-α plus IFN-γ freely attached on the polymeric plate (free drug). It is revealed that the co-immobilized drug leads to significant cell arrest in the S phase or G(1) and G(2) phase and offer high efficiency in mediating a caspase-dependent apoptosis via p53 transcriptional regulation. Moreover, upon the treatment by the co-immobilized drug, the two gynecologic cancer cell lines show different phosphorylation sites of p53 and then different caspase-dependent apoptosis pathways. The present work sheds deep insights into the p53 regulation mechanism responsible for the high anti-cancer efficiency of the co-immobilized TNF-α plus IFN-γ polymeric drug against MCF-7 and OVCAR-3.

Abstract
In order to prohibit the toxicity of free IFN-γ plus TNF-α in treating human cervical cancer HeLa cells, two kinds of thermoplastic polyurethane (polyester/polyether) biomaterials with co-immobilized IFN-γ plus TNF-α on the surfaces are prepared. The programmed cell death of HeLa induced by these biomaterials is investigated. The surface modification of these biomaterials with co-immobilized IFN-γ plus TNF-α is performed by the photo-immobilization method, and the surface structures are characterized by various techniques. The cell morphology, cell mortality, cell cycle arrest, and functional status of caspases, upon the treatment by these biomaterials, are characterized. The results show that the as-prepared biomaterials have high inhibition activity against the growth of HeLa cells. The HeLa cells mediated by the two kinds of biomaterials are mainly arrested in the G(1) phase, while those cells mediated directly by free IFN-γ plus TNF-α are mainly arrested in the S phase. It is suggested that the programmed cell death mechanism induced by these two kinds of biomaterials is both caspase-dependent and caspase-independent. Our data provide the knowledge of microscopic surface structures and cell biology basis for synthesizing the thermoplastic polyurethane biomaterials with co-immobilized IFN-γ plus TNF-α, which are promising for novel therapeutics (e.g. drug cup) design for cervical cancer patients.
