The nociceptin/orphanin FQ receptor system as a target to alleviate cancer-induced bone pain in rats: Model validation and pharmacological evaluation. Br J Pharmacol 2021; 178:1995-2007. [PMID: 31724155 PMCID: PMC8246843 DOI: 10.1111/bph.14899] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2019] [Revised: 08/13/2019] [Accepted: 09/27/2019] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND AND PURPOSE Cancer-induced bone pain remains inadequately controlled, and current standard of care analgesics is accompanied by several side effects. Nociceptin/orphanin FQ peptide (NOP) receptor agonists have demonstrated broad analgesic properties in rodent neuropathic and inflammatory pain models. Here, we investigate the analgesic potential of NOP receptor activation in a rodent cancer-induced bone pain model. EXPERIMENTAL APPROACH Model validation by intratibial inoculation in male Sprague Dawley rats was performed with varying MRMT-1/Luc2 cell quantities (0.5-1.5 × 106 ·ml-1 ) and a behavioural battery (>14 days post-surgery) including evoked and non-evoked readouts: paw pressure test, cold plate, von Frey, open field, and weight distribution. Anti-allodynic potential of the endogenous NOP receptor ligand nociceptin (i.t.) and NOP receptor agonist Ro65-6570 ( i.p.) was tested using von Frey filaments, followed by a combination experiment with Ro65-6570 and the NOP receptor antagonist J-113397 (i.p.). Plasma cytokine levels and NOP receptor gene expression in dorsal root ganglion (DRG, L4-L6) and bone marrow were examined. KEY RESULTS Inoculation with 1.5 × 106 ·ml-1 of MRMT-1/Luc2 cells resulted in a robust and progressive pain-related phenotype. Nociceptin and Ro65-6570 treatment inhibited cancer-induced mechanical allodynia. J-113397 selectively antagonized the effect of Ro65-6570. MRMT-1/Luc2-bearing animals demonstrated elevated plasma cytokine levels of IL-4, IL-5, IL-6 and IL-10 plus unaltered NOP-r gene expression in DRG and reduced expression in bone marrow. CONCLUSION AND IMPLICATIONS Nociceptin and Ro65-6570 selectively and dose-dependently reversed cancer-induced bone pain-like behaviour. The NOP receptor system may be a potential target for cancer-induced bone pain treatment.

Abstract
The presence of inflammatory cells and their products in the tumor microenvironment plays a crucial role in the pathogenesis of a tumor. Releasing the cytokines from a host in response to infection and inflammation can inhibit tumor growth and progression. However, tumor cells can also respond to the host cytokines with increasing the growth/invasion/metastasis. Bladder cancer (BC) is one of the most common cancers in the world. The microenvironment of a bladder tumor has been indicated to be rich in growth factors/inflammatory cytokines that can induce the tumor growth/progression and also suppress the immune system. On the contrary, modulate of the cancer progression has been shown following upregulation of the cytokines-related pathways that suggested the cytokines as potential therapeutic targets. In this study, we provide a summary of cytokines that are involved in BC formation/regression with both inflammatory and anti-inflammatory properties. A more accurate understanding of tumor microenvironment creates favorable conditions for cytokines targeting to treat BC.

Abstract
Leukocyte cell-derived chemotaxin 2 (Lect2) is a chemokine-like chemotactic factor that has been identified as a downstream target of the Wnt signalling pathway. Whilst the primary function of Lect2 is thought to be in modulating the inflammatory process, it has recently been implicated as a potential inhibitor of the Wnt pathway. Deregulation of the Wnt pathway, often due to loss of the negative regulator APC, is found in ~80% of colorectal cancer (CRC). Here we have used the ApcMin/+Lect2-/- mouse model to characterise the role of Lect2 in Wnt-driven intestinal tumourigenesis. Histopathological, immunohistochemical, PCR and flow cytometry analysis were employed to identify the role of Lect2 in the intestine. The ApcMin/+Lect2-/- mice had a reduced mean survival and a significantly increased number of adenomas in the small intestine with increased severity. Analysis of Lect2 loss indicated it had no effect on the Wnt pathway in the intestine but significant differences were observed in circulating inflammatory markers, CD4+ T cells, and T cell lineage-specification factors. In summary, in the murine intestine loss of Lect2 promotes the initiation and progression of Wnt-driven colorectal cancer. This protection is performed independently of the Wnt signalling pathway and is associated with an altered inflammatory environment during Wnt-driven tumorigenesis.

Role of Cyclooxygenase-2 Pathway in Creating an Immunosuppressive Microenvironment and in Initiation and Progression of Wilms' Tumor. Neoplasia 2017; 19:237-249. [PMID: 28254151 PMCID: PMC6197604 DOI: 10.1016/j.neo.2016.07.009] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2016] [Revised: 07/19/2016] [Accepted: 07/21/2016] [Indexed: 12/29/2022]
Abstract
Wilms' tumors (WT), which accountfor 6% of all childhood cancers, arise from dysregulated differentiation of nephrogenic progenitor cells from embryonic kidneys. Though there is an improvement in the prognosis of WT, still 10% of patients with WT die due to recurrence. Thus more effective treatment approaches are necessary. We previously characterized the inflammatory microenvironment in human WT and observed the robust expression of COX-2. The aim of this study was to extend our studies to analyze the role of COX-2 pathway components in WT progression using a mouse model of WT. Herein, COX-2 pathway components such as COX-2, HIF1-α, p-ERK1/2, and p-STAT3 were upregulated in mouse and human tumor tissues. In our RPPA analysis, COX-2 was up-regulated in M15 cells after Wt1 gene was knocked down. Flow cytometry analysis showed the increased infiltration of immune suppressive inflammatory cells such as pDC's and Treg cells in tumors. The chemotactic chemokines responsible for the infiltration of these cells were also induced in CCR5 and CXCR4 dependent manner respectively. The immunosuppressive cytokines IL-10, TGF-β, and TNF-α were also up-regulated. Furthermore, more pronounced Th2 and Treg induced cytokine response was observed than Th1 response in tumors. Basing on all these evidences it is speculated that COX-2 pathway may be a beneficial target for the treatment of WT. It may be most effective as an adjuvant therapy together with other inhibitors. Thus, our current study provides a good rationale for initiating animal studies to confirm the efficacy of COX-2 inhibitors in decreasing tumor cell growth in vivo.

Interleukin-4 receptor signaling and its binding mechanism: A therapeutic insight from inhibitors tool box. Cytokine Growth Factor Rev 2016; 32:3-15.

Abstract
Studies on Interlukin-4 (IL-4) disclosed great deal of information about its various physiological and pathological roles. All these roles depend upon its interaction and signaling through either type-I (IL-4Rα/common γ-chain) or type-II (IL-4Rα/IL-13Rα) receptors. Another cytokine, IL-13, shares some of the functions of IL-4, because both cytokines use a common receptor subunit, IL-4Rα. Here in this review, we discuss the structural details of IL-4 and IL-4Rα subunit and the structural similarities between IL-4 and IL-13. We also describe detailed chemistry of type-I and type-II receptor complexes and their signaling pathways. Furthermore, we elaborate the strength of type-II hetero dimer signals in response to IL-4 and IL-13. These cytokines are prime players in pathogenesis of allergic asthma, allergic hypersensitivity, different cancers, and HIV infection. Recent advances in the structural and binding chemistry of these cytokines various types of inhibitors were designed to block the interaction of IL-4 and IL-13 with their receptor, including several IL-4 mutant analogs and IL-4 antagonistic antibodies. Moreover, different targeted immunotoxins, which is a fusion of cytokine protein with a toxin or suicidal gene, are the new class of inhibitors to prevent cancer progression. In addition few small molecular inhibitors such as flavonoids have also been developed which are capable of binding with high affinity to IL-4Rα and, therefore, can be very effective in blocking IL-4-mediated responses.

Abstract
The common gamma chain (γc) receptor family of cytokines including interleukin-2 (IL-2), IL-4, IL-7, IL-9, IL-15, and IL-21 has the common feature of sharing γc signaling subunit of their receptors. The γc cytokines have unique biological effects that regulate differentiation, survival and activation of multiple lymphocyte lineages and control proliferation of malignant cell by influencing tumor environment. It has been also described that different types of lymphoid leukemia and lymphoma exhibit expression of divergent γc cytokines and their receptors, as they may promote malignant transformation of lymphoid cells or on the contrary lead to tumor regression by inducing cell-cycle arrest. Therefore, cytokine-based or cytokine-directed blockade in cancer immunotherapy has currently revolutionized the development of cancer treatment. In this review, we will discuss about the role of γc cytokines and their signaling pathways in hematological malignancies and also propose a novel alternative approach that regulates γc cytokine responsiveness by γc in hematological malignancies.

Abstract
Cytokines are low molecular weight regulatory proteins or glycoprotein that modulates the intensity and duration of immune response by stimulating or inhibiting the activation, proliferation, and/or differentiation of target cells. Different cytokines are known to have diverse role in breast cancer initiation and progression. Interleukin-10 (IL-10), a pleiotropic anti-inflammatory cytokine, induces immunosuppression and assists in escape from tumor immune surveillance. Like several other cytokines, IL-10 also can exert dual proliferative and inhibitory effect on breast tumor cells indicating a complex role of IL-10 in breast cancer initiation and progression. In this review, we tried to put together a comprehensive current view on significance of IL-10 in promotion, inhibition, and importance as prognosticator in breast cancer based on in vitro, in vivo, and clinical evidences. For literature collection, we conducted PubMed search with keywords "IL-10" and "breast cancer".

Abstract
The increase of interleukin-4 (IL-4) level in tumor environment and the up-regulation of IL-4 receptor (IL-4R) on tumor cells have been long observed. However, their significance for tumor development has not been investigated. Here, we found that endogenous IL-4 promotes tumor growth because neutralizing IL-4 by 11B11 monoclonal antibody (mAb) significantly delayed the growth of MCA205 fibrosarcoma. We also observed that tumor cells with higher IL-4R expression have more chances to survive in immunocompetent mice. To investigate how endogenous IL-4 influences tumor growth, we established a pair of tumor cells with or without IL-4R expression from the common parental cells. IL-4R-competent tumors exhibit increased growth compared with its IL-4R-deficient counterparts when inoculated into syngeneic mice. This growth advantage was still kept in IL-4R knockout mice but was abrogated in mice given i.p. with IL-4 neutralizing mAb. In vitro analyses indicate that IL-4 neither affects the proliferation of tumor cells nor changes the expression of several immune-related molecules, such as MHC-I, Fas, and B7-H3. Nonetheless, IL-4 up-regulates antiapoptotic gene expression in tumor cells and reduces apoptosis of tumor cells in vivo, as evidenced by real-time PCR, immunoblotting, and TUNEL staining. These findings were helpful to understand the long clinical observation and revealed that endogenous IL-4, the product of host immune response, can be used by tumor cells to facilitate their growth.

Abstract
The recently cloned human gene named "placental immunoregulatory ferritin" (PLIF) is a pregnancy-related immunomodulator. Recombinant PLIF and its bioactive domain C48 are immune-suppressive and induce pronounced IL-10 production by immune cells. PLIF is expressed in the placenta and breast cancer cells. Blocking PLIF in pregnant mice by anti-C48 antibodies inhibited placental and fetal growth and modulated the cytokine network. It has been revealed that anti-C48 treatment inhibited MCF-7 tumor growth in nude mice. However, this significant effect was observed only in those transfused with human peripheral blood mononuclear cells. Blocking PLIF in tumor-engrafted human immune cell transfused mice resulted in massive infiltration of human CD45+ cells (mainly CD8+ T cells), both intratumorally and in the tumor periphery, and a significant number of caspase-3+ cells. In vitro, anti-C48 treatment of MCF-7 tumor cells cocultured with human lymphocytes induced a significant increase in interferon-gamma secretion. We conclude that blocking PLIF inhibits breast cancer growth, possibly by an effect on the cytokine network in immune cells and on breakdown of immunosuppression.

Abstract
Ferritin, a cytosolic iron storage protein composed of 24 subunits of heavy chain and light chain, is an intracellular protein primarily involved in iron metabolism. It can sequester up to 4500 ferric ions in its inner core to protect cells against toxicity of iron. Ferritin is known to play important roles in detoxification and is also involved in immunity processes. In this study, a full-length ferritin cDNA was cloned from the haemocyte of the Pacific white shrimp, Litopenaeus vannamei: it comprises 1249 bp, including 132 bp in the 5'-untranslated region, 510 bp in the open reading frame which encodes 170 amino acid residues, and 607 bp in the 3'-untranslated region. Alignments of the deduced amino acid sequence showed that the Pacific white shrimp ferritin shares 74%, 69%, 62%, 67%, 50% and 48% identity with crayfish, tick, brine shrimp, oyster, human and rat, respectively. The tissue-specific expression pattern was examined by reverse transcription polymerase chain reaction and real-time quantitative PCR. The ferritin mRNA is expressed in various tissues of the shrimp in the order of haemocyte, midgut gland, brain ganglion, gill, hepatopancreas, abdominal ganglion, eyestalk, muscle, thoracic ganglion, and heart.

Abstract
MG7-Ag is a human gastric-carcinoma-associated antigen with a high specificity. So far it is remained unclear whether MG7-Ag is correlated with the in vivo cellular immune response of patients with gastric cancer. In this study, we detected the expression of the T cell receptor (TCR) repertoire of T cell subpopulations and cytokines in tumor-infiltrating lymphocytes (TIL), peripheral blood lymphocytes (PBL), and residue benign mucosal lymphocytes (NML) of patients with gastric cancer using semiquantitative RT-PCR. Our data showed that the expanded clones in CD8(+) NML and TIL and CD4+ NML and PBL in MG7-Ag-positive patients were significantly fewer than those of MG7-Ag-negative patients (p = 0.0360; p = 0.0026; p = 0.0065 p = 0.0109, respectively). The levels of IL-8 in CD8(+) TIL and TNF in CD4(+) TIL from the MG7-Ag-positive group were significantly higher than those from the MG7-Ag-negative group (p = 0.0302; p = 0.0177, respectively). Taken together, the results demonstrated a weaker T cell immune response and more proinflammatory cytokine secretion in MG7-Ag-positive patients with gastric cancer than in MG7-Ag-negative ones. This likely contributes to the poor prognosis in MG7-Ag-positive gastric-cancer patients.

Abstract
We recently proposed that Th1 and Th2 cytokines exert opposite effects on the pathogenesis and clinical outcome of organ-specific autoimmunity by altering the expression of genes involved in target cell survival. Because a Th2 response against tumors is associated with poor prognosis, we investigated the ability of IL-4 to protect tumor cells from death receptor- and chemotherapy-induced apoptosis. We found that IL-4 treatment significantly reduced CD95 (Fas/APO-1)- and chemotherapeutic drug-induced apoptosis in prostate, breast, and bladder tumor cell lines. Analysis of antiapoptotic protein expression revealed that IL-4 stimulation resulted in up-regulation of cellular (c) FLIP/FLAME-1 and Bcl-x(L). Exogenous expression of cFLIP/FLAME-1 inhibited apoptosis induced by CD95 and to a lesser extent by chemotherapy, while tumor cells transduced with Bcl-x(L) were substantially protected both from CD95 and chemotherapeutic drug stimulation. Moreover, consistent IL-4 production and high expression of both cFLIP/FLAME-1 and Bcl-x(L) were observed in primary prostate, breast, and bladder cancer in vivo. Finally, primary breast cancer cells acquired sensitivity to apoptosis in vitro only in the absence of IL-4. Thus, IL-4 protects tumor cells from CD95- and chemotherapy-induced apoptosis through the up-regulation of antiapoptotic proteins such as cFLIP/FLAME-1 and Bcl-x(L). These findings may provide useful information for the development of therapeutic strategies aimed at restoring the functionality of apoptotic pathways in tumor cells.

Abstract
Incubation of primary cultures of parenchymal hepatocytes in a conditioned medium (CM), collected over the first 3 h of serum-free rat hepatocyte culture (CM(0-3)), induces a time dependent increase of the frequency of apoptotic cells which is accompanied by prominent changes of cell morphology. Short-term treatment with CM(0-3) for the first 3 h of culture is sufficient to significantly (P < 0.05) increase the frequency of apoptotic cells, however, the effect is more pronounced upon long-term treatment. Although apoptosis induction by CM(0-3) is independent of the timepoint when cultivation in CM(0-3) starts, our results suggest that the sensitivity for apoptosis induction by CM(0-3) is increased during the phase of attachment. Purification of CM(0-3) resulted in a fraction which significantly (P < 0.05) induced apoptosis at concentrations >/=10 ng/ml. Exposure of cultures to concentrations >/=1 microg/ml of purified CM(0-3) gave rise to a prominent cytotoxic effect as indicated by the massive occurrence of necrotic cells. Biochemical analysis showed that the purified fraction of CM(0-3) contains acidic ferritins with molecular weight of 23 and 43 kDa. Strikingly, both share homologies with placental isoferritins (PLF), for which growth inhibitory and immunosuppressive effects have been demonstrated by several investigations. Therefore, our results provide evidence that rat hepatocytes produce PLF or PLF-related acidic isoferritins which are able to induce apoptosis.

Abstract
Heavy chain ferritin (H-ferritin) is a component of the iron-binding protein, ferritin. We have previously shown that H-ferritin inhibits anti-CD3-stimulated lymphocyte proliferation and that this was due to increased production of interleukin-10 (IL-10). In the present study we have shown that induction of IL-10 production was due to effects of H-ferritin on adherent antigen-presenting cells (APCs) in blood and monocyte-derived dendritic cells (MoDCs). IL-10 was produced by a subpopulation of CD4 T cells, which expressed the CD25 component of the IL-2 receptor and the CTLA-4 receptor characteristic of regulatory T cells. The changes induced in MoDCs were compared with those induced by CD40L and their significance tested by inhibition with monoclonal antibodies. These studies indicated that H-ferritin induced relatively greater expression of CD86 and B7-H1 on MoDCs and that monoclonal antibodies against their receptors, CTLA-4 and programmed death receptor-1 (PD-1), inhibited IL-10 production from the regulatory T cells. H-ferritin did not appear to induce direct production of the cytokines IL-2, IL-4, IL-6, IL-10, IL-12, or interferon-gamma from the DCs. These results are consistent with the thesis that H-ferritin induces B7-H1 and CD86 (B7-2) on APCs, which in turn induce IL-10 production from regulatory T cells. This is possibly one mechanism by which melanoma cells may induce changes in APCs in the vicinity of the tumor and result in suppression of immune responses by induction of regulatory T cells.

Abstract
Ferritin is a ubiquitous iron storage protein existing in multiple isoforms composed of 24 heavy and light chain subunits. We describe here a third ferritin-related subunit cloned from human placenta cDNA library and named PLIF (placental immunomodulatory ferritin). The PLIF coding region is composed of ferritin heavy chain (FTH) sequence lacking the 65 C-terminal amino acids, which are substituted with a novel 48 amino acid domain (C48). In contrast to FTH, PLIF mRNA does not include the iron response element in the 5'-untranslated region, suggesting that PLIF synthesis is not regulated by iron. The linkage between the FTH and C48 domains created a restriction site for EcoRI. PLIF protein was found to localize in syncytiotrophoblasts of placentas (8 weeks of gestation) at the fetal-maternal interface. Increased levels of PLIF transcript and protein were also detected in the breast carcinoma cell lines T47D and MCF-7 but not in the benign corresponding cell line HBL-100. In vitro, PLIF was shown to down-modulate mixed lymphocyte reactions and to inhibit the proliferation of peripheral blood mononuclear cells stimulated with OKT3. The accumulated data indicate that PLIF is an embryonic immune factor involved in down-modulating the maternal immune recognition of the embryo toward anergy. This mechanism may have been adapted by breast cancer cells over expressing PLIF.

Abstract
Cultured melanoma cells release soluble factors that influence immune responses. Screening of a cDNA library with anti-sera from a melanoma patient identified an immunoreactive plaque, which encoded heavy-chain ferritin (H-ferritin). Previous studies have drawn attention to the immunosuppressive effects of this molecule and prompted further studies on its biochemical and functional properties in human melanoma. These studies demonstrated, firstly, that H-ferritin appeared to be secreted by melanoma cells, as shown by immunoprecipitation of a 21.5 kDa band from supernatants. It was also detected in extracts of melanoma cells by Western blotting as 43 and 64 kDa dimers and trimers of the 21.5 kDa fraction. Secondly, flow-cytometric analysis of H- and light-chain ferritin (L-ferritin) expression on melanoma showed a wide variation in L-ferritin expression and consequently of the ratio of H- to L-ferritin expression. Suppression of mitogenic responses of lymphocytes to anti-CD3 showed a correlation with the ratio of H- to L-ferritin in the supernatants and was specific for H-ferritin, as shown by inhibition studies with a monoclonal antibody (MAb) against H-ferritin. Similar results were obtained with H- and L-ferritin from other sources. Suppression of mitogenic responses of lymphocytes to anti-CD3 by H-ferritin was inhibited using a MAb against IL-10, which suggested that the immunosuppressive effect of H-ferritin was mediated by IL-10. Assays of cytokine production from anti-CD3-stimulated lymphocytes showed that H-ferritin markedly increased production of IL-10 and IFN-gamma and had only slight effects on IL-2 and IL-4 production. Our results suggest that melanoma cells may be a major source of H-ferritin and that production of the latter may account for some of the immunosuppressive effects of melanoma.

Abstract
OBJECTIVE Human placental isoferritin, which is composed of a 43-kd protein subunit, is exclusively reactive with the CM-H9 monoclonal antibody. The p43 exerts immunosuppressive activity during pregnancy. The aim of this study was to localize the expression of p43 in the maternal-fetal tissue interface during normal gestation. STUDY DESIGN Villous tissues samples were collected between 5 and 20 weeks' gestation and at term from uncomplicated pregnancies. Immunohistochemical localization of p43 was performed with CM-H9 monoclonal antibody. RESULTS During the first trimester p43 was highly expressed in syncytiotrophoblast, Hofbauer cells, and decidual macrophages. From 15 weeks' gestation onward expression in the syncytiotrophoblast was below the level of detection; however, p43 was demonstrated in villous Hofbauer cells and decidual macrophages throughout gestation. CONCLUSIONS Expression of p43 was demonstrated on both sides of the maternal-fetal tissue interface, with localization dependent on gestational age. This may suggest its immunologic function throughout pregnancy. First-trimester syncytiotrophoblast displayed high p43 levels, which disappeared later on, whereas maternal serum p43 level continued to increase, which suggests an extraplacental source for p43.
