Abstract
Nanoparticle-based cell differentiation therapy has attracted increasing research interest as it is a promising substitute for conventional cancer treatment methods. Here, the topological insulator bismuth selenide nanoparticle (Bi2Se3 NP) was core-shelled with silver (Ag@Bi2Se3) to represent remarkable biocompatibility and plasmonic features (ca. 2.3 times higher than those of Ag nanoparticle). Moreover, a newly developed RNA three-way junction (3WJ) structure was designed for the quad-functionalization of any type of nanoparticle and surface. One leg of the 3WJ was attached to the Ag@Bi2Se3, and the other leg harbored a cell-penetrating RNA and a florescence tag. The third leg was designed to inhibit micro-RNA-17 (miR-17) and to further release retinoic acid (RA). A new drug delivery mechanism was developed for the slow release of RA inside the cytosol based on the prerequisite inhibition of miR-17 using a strand displacement strategy. In this paper, we report a simple methodology for resolving the hydrophobicity challenges of RA by its conjugation with a RNA strand (RA/R) through a stimulus-responsive cross-linker. The developed nanobiohybrid material could fully differentiate SH-SY5Y cancer cells into neurons and stop their growth in 6 days without requiring sequential treatments which has not been reported yet. Using a surface-enhanced Raman spectroscopy technique, the RA delivery and the cell differentiation process were monitored nondestructively in real time. The fabricated nanobiohybrid material could open the new horizons in the fabrication of different diagnostic/therapeutic agents.

Abstract
The MYCN protooncogene is involved in the control of cell proliferation, differentiation, and survival of neuroblasts. Deregulation of MYCN by gene amplification contributes to neuroblastoma development and is strongly correlated to advanced disease and poor outcome, emphasizing the urge for new therapeutic strategies targeting MYCN function. The transcription factor N-Myc, encoded by MYCN, regulates numerous genes together with its partner Max, which also functions as a cofactor for the Mad/Mnt family of Myc antagonists/transcriptional repressors. We and others have previously reported that IFN-gamma synergistically potentiates retinoic acid (RA)-induced sympathetic differentiation and growth inhibition in neuroblastoma cells. This study shows that combined treatment of MYCN-amplified neuroblastoma cells with RA+IFN-gamma down-regulates N-Myc protein expression through increased protein turnover, up-regulates Mad1 mRNA and protein, and reduces N-Myc/Max heterodimerization. This results in a shift of occupancy at the ornithine decarboxylase N-Myc/Mad1 target promoter in vivo from N-Myc/Max to Mad1/Max predominance, correlating with histone H4 deacetylation, indicative of a chromatin structure typical of a transcriptionally repressed state. This is further supported by data showing that RA+IFN-gamma treatment strongly represses expression of N-Myc/Mad1 target genes ornithine decarboxylase and hTERT. Our results suggest that combined IFN-gamma and RA signaling can form a basis for new therapeutic strategies targeting N-Myc function for patients with high-risk, MYCN-amplified neuroblastoma.

Abstract
OBJECTIVE The human MUC4 mucin plays an important role in the pathogenesis of pancreatic cancer. Recently, we have demonstrated that MUC4 expression in pancreatic tumor cells is regulated by interferon-gamma (IFNgamma) and by retinoic acid via transforming growth factor beta 2 (TGFbeta-2). In the present study, we established the pathobiological association of various cytokines and MUC4 in pancreatic tumor tissues and tumor cell lines. METHODS Using semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) and/or immunohistochemical analyses, we examined the expression of MUC4, IFNgamma, TGFbetas, and several immunologically relevant cytokines in a panel of 11 pancreatic adenocarcinomas (PA), three normal pancreatic (NP) tissue specimens, and 11 pancreatic tumor cell lines. RESULTS Our data revealed that both MUC4 and IFNgamma were expressed at moderate to high levels in the majority of PA, while being undetectable in NP. Moreover, transcript for interleukin 2 (IL-2), a known marker of activated T helper 1 (TH1) lymphocytes, exhibited an expression profile similar to IFNgamma, suggesting a role of these immune effector cells as a potential source of IFNgamma in PA. Of note, IFNgamma protein was detected in the inflamed tissues neighboring tumor areas. Furthermore, TGFbetas were expressed by most cell lines and frequently upregulated in PA compared with NP. Interestingly, both IL-12 and IL-10, two key cytokines of the TH1 and TH2 pathways, respectively, were expressed at higher levels in PA relative to NP. CONCLUSIONS These observations support the potential implication of IFNgamma and TGFbetas in MUC4 regulation in vivo and suggest a complex interaction of TH1 and TH2 signaling in the pancreatic tumor microenvironment. These findings may provide useful insights into the pathobiology of pancreatic cancer.

Abstract
The prognosis of patients with advanced stages of neuroblastoma with N-myc amplification remains poor despite escalated therapy, a situation that has called for alternative therapeutic approaches. Neuroblastoma cells, which represent immature peripheral neuronal cells, treated with certain physiologic and nonphysiologic agents such as retinoic acid (RA), phorbol esters and interferons (IFN) in vitro undergo cellular differentiation and stop to divide, a process that mimics normal neuronal development. Such "differentiation therapy" using RA after autologous bone marrow transplantation has recently given encouraging results in neuroblastoma patients with advanced disease. Considering approaches for improved differentiation therapy, we investigated possible synergistic effects of combining agents known to influence neuroblastoma growth and differentiation in vitro. Our results show that combined treatment with IFN-gamma and RA or the phorbol ester 12-O-tetradecanoyl-phorbol acetate (TPA) had synergistic or enhancing effects on morphologic differentiation and neurite outgrowth in 5 of 5 neuroblastoma cell lines, 3 of which expressed very high levels of N-myc mRNA due to N-myc amplification. The combinations RA+IFN-gamma or TPA+IFN-gamma also enhanced induced growth inhibition in all 5 cell lines, in several cases resulting in complete growth arrest under conditions where cells stimulated with either agent alone continued to grow. The phenotypic effects of the combined RA+IFN-gamma or TPA+IFN-gamma treatments were in most, but not all, investigated cases accompanied by moderate reductions in N-myc expression, suggesting that the cooperative signals may counteract N-Myc activity at several levels. The cooperativity between IFN-gamma and other differentiation signals may be relevant for approaches to improve the therapy for high-risk neuroblastoma with N-myc-amplification.

Abstract
Neuroblastoma, a neural crest-derived childhood tumor of the sympathetic nervous system, may in some cases differentiate to a benign ganglioneuroma or regress due to apoptosis. However, the majority of neuroblastomas are diagnosed as metastatic tumors with a poor prognosis despite intensive multimodal therapy. The neuropeptide somatostatin (SOM) has been shown to inhibit neuroblastoma growth and induce apoptosis in vitro. Therapeutic effects of SOM analogues are dependent on tumor expression of high-affinity receptors. In the present study, human neuroblastoma SH-SY5Y cells were grown as xenografts in nude rats. In vivo SOM receptor expression in the xenografts was identified using scintigraphy with 111In-pentetreotide. Rats were randomized to treatment with the long-acting SOM analogue octreotide (10 microg s.c. every 12 h), 13-cis-retinoic acid (4 mg orally every 24 h), or vasoactive intestinal peptide (40 microg s.c. every 24 h) and compared with controls. Tumor volume was assessed every second day and tumor weight after 10-12 d. Octreotide treatment inhibited neuroblastoma growth significantly with reduced tumor volumes at 10 and 12 d compared with untreated controls (mean 3.56 and 4.24 versus 6.48 and 8.01 mL, respectively; p < 0.01). Also, tumor weights after 10-12 d were reduced in octreotide-treated animals (n = 8, median weight 2.90 g, range 1.67-5.57 g) compared with untreated rats (n = 14, 7.54 g, 1.65-10.82 g, p = 0.005). Serum IGF-I decreased significantly over time both in rats treated with octreotide and in untreated controls. It is concluded that treatment with the SOM analogue octreotide may significantly decrease neuroblastoma tumor growth in vivo. Further studies are warranted to establish the role of SOM analogues in the treatment of children with unfavorable neuroblastoma.

Abstract
The N-myc oncogene plays a key role in the biology of neuroblastoma and the differentiation process. N-myc expression is associated with metastatic disease, as well as the undifferentiated state of normal neuroblasts migrating from the neural crest during embryogenesis. Its down-regulation is a pivotal event in the differentiation of neuroblastoma cells by retinoic acid (RA). Our previous work has shown that RA works synergistically with other agents, such as interferon-gamma (IFN-gamma), to down-regulate N-myc expression and induce differentiation. The present study demonstrates that IFN-gamma, like RA, decreases N-myc transcription. However, functional analysis of N-myc upstream regulatory sequences using 5' deletion mutants of a promoter-CAT construct containing germ line sequences from nucleotide position -887 to +151 showed that IFN-gamma and RA act through different sites on the N-myc promoter. In addition to its transcriptional effect, IFN-gamma was also found to shorten the half-life of N-myc mRNA. Taken together, these findings provide a mechanistic basis for the synergistic action of IFN-gamma and RA in inducing neuroblastoma differentiation and a rationale for the possible development of combination differentiation therapy for clinical use.

Abstract
Neuroblastomas are neural crest-derived tumors that contain neuronal, melanocyte, and Schwann cell precursors. We examined the effects of treatment with gamma-interferon (gamma-IFN) and nerve growth factor (NGF), alone, and in combination, on these progenitor subpopulations in the human neuroblastoma cell line, SH-SY5Y. Using fluorescence-activated flow cytometry (FACS), changes in expression of three differentiation-specific or -associated marker proteins, the 200 kD neurofilament protein, the myelin basic protein, and the S-100 protein, were analyzed. Growth rates and morphological changes associated with each treatment over the 2-wk incubation period were noted. The greatest effects were observed with combined IFN + NGF treatment. These were significant increases in expression of all three proteins, distinctive morphological signs of differentiation, and extensive inhibition of proliferation compared to control cultures. Treatment with NGF alone resulted in increased neurofilament protein expression and in the length and number of neurite extensions, but there was no effect on the growth rate. IFN induced striking morphological changes, significant inhibition of growth, and changes in protein expression that correlated with neuronal to non-neuronal subpopulation shifts due to the death of differentiated cells. When treatment was discontinued after 15 d, the morphological changes induced by NGF were reversed within 2-3 d, while those induced by IFN +/- NGF were present up to 4 wk post-treatment. Small, neuroblastic colonies were observed throughout the treatment period and within 4-6 wk after the cessation of treatment this cell-type fully reconstituted the cultures suggesting the presence of a stem cell. Our results indicate that treatment with gamma-IFN +/- NGF can regulate growth and induce, either stem cells or progenitor neuronal, Schwann and melanocyte subpopulations in the SH-SY5Y cell line to irreversibly differentiate.

Abstract
By secreting granulocyte/macrophage colony-stimulating factor (GM-CSF), metastatic Lewis lung carcinoma (LLC-LN7) tumors induce the appearance of myelopoiesis-associated immune-suppressor cells that resemble granulocytic-macrophage (GM) progenitor cells. The presence of these GM-suppressor cells in mice bearing LLC-LN7 tumors was associated with a reduced capacity of splenic T cells to proliferate in response to interleukin-2 (IL-2). Administration of low doses of 100 U interferon gamma (IFN gamma) plus 10 U tumor necrosis factor alpha (TNF alpha) to the tumor bearers, a combination treatment that we previously showed to diminish the presence of GM-suppressor cells synergistically, restored proliferative responsiveness of the splenic T cells to IL-2. These LLC-LN7-bearing mice were also examined for whether cells that phenotypically resemble GM-progenitor cells (ER-MP12+ cells) infiltrate the tumor mass. ER-MP12+ cells composed approximately 10% of the cells isolated from dissociated tumors of mice that had been treated with placebo or with either IFN gamma or TNF alpha alone, but IFN gamma/TNF alpha therapy markedly reduced the number of tumor-infiltrating ER-MP12+ suppressor cells. The IFN gamma/TNF alpha treatment to eliminate GM-suppressor cells and restore T cell responsiveness to IL-2 was next coupled with low dose IL-2 therapy (100 U twice daily). Addition of IL-2 to the treatment regimen did not significantly influence the effectiveness of the IFN gamma/TNF alpha treatment in eliminating GM-suppressor cells from the LLC-LN7 tumor mass. However, inclusion of IL-2 with the IFN gamma/TNF alpha treatment regimen enhanced the CD8+, but not the CD4+, cell content within the tumor, and diminished the number of metastatic lung nodules within the mice. When these tumors were excised, dissociated, and bulk-cultured with a low dose of IL-2, an increased level of cytotoxic T lymphocyte (CTL) activity was generated in the TIL cultures from mice that had received IFN gamma/TNF alpha plus IL-2 treatments. A lesser but detectable level of CTL activity was generated in TIL cultures from mice that were treated with only IFN gamma/TNF alpha, while no CTL activity was generated in tumor cultures from mice receiving only placebo or low-dose IL-2. These results suggest the effectiveness of IFN gamma plus TNF alpha therapy in restoring IL-2 responsiveness in mice bearing GM-suppressor cell-inducing tumors and at enhancing both the intratumoral CD8+ cell content and the generation of CTL activity in bulk cultures of these tumors.
