Abstract Decreased activity of osteoblasts (OB) contributes to osteolytic lesions in multiple myeloma (MM). Dickkopf-1 (DKK1) is a soluble Wnt inhibitor produced by MM cells that inhibits osteoblastogenesis in the bone marrow (BM) microenvironment. DKK1, also present in MM patient plasma, has been shown to inhibit the differentiation of osteoblast precursor cells in vitro, and its plasma level correlates with focal bone lesions in MM. Therefore, we have evaluated DKK1 as a target in MM in the context of the BM microenvironment. We first analyzed the effects of a DKK1 neutralizing antibody (BHQ880) on OB differentiation. Anti-DKK1 Ab was able to increase differentiation of mesenchymal stem cells (MSCs) to OB and reduce IL-6 levels following MSC differentiation to OB. While OB activity in MSCs cultured with osteoblast differentiation media was reduced in the presence of INA-6 MM cells, treatment with DKK1 neutralizing antibody was able to restore OB activity in a dose-dependent manner, overcoming the negative effect of MM cells. We did not observe a direct effect of this Ab on growth or survival of human MM cell lines. However, when a panel of MM cell lines was cultured with BM stromal cells (BMSC), the Ab induced significant growth inhibitory effects on MM cells, associated with downregulation of IL-6 produced by MSCs. To evaluate the in vivo bone and antitumor effects of anti-DKK1 Ab treatment on MM cells in the human microenvironment, we used a SCID-hu murine model, using INA-6 MM cells. In this model we observed a direct correlation between the level of soluble human DKK1 in murine blood and the tumor growth. Following treatment with BHQ880, by bone histology analysis, we observed increased trabecular bone and numbers of OBs in the retrieved bone chip from BHQ880 treated mice compared to control mice, one month after initial dose. We also found an increase in human osteocalcin in the serum of BHQ880-treated mice compared to the controls, suggesting an increase in OB activity. Interestingly, we observed suppression of myeloma growth, measured by changes in serum level of soluble huIL6sR, 4 weeks following BHQ880 treatment of the mice. These results support DKK1 as an important therapeutic target in myeloma and provide the rationale for clinical evaluation of this molecule in MM to improve bone disease and to inhibit MM growth.

Abstract Decreased activity of osteoblasts (OBs) contributes to osteolytic lesions in multiple myeloma (MM). The production of the soluble Wnt inhibitor Dickkopf-1 (DKK1) by MM cells inhibits OB activity, and its serum level correlates with focal bone lesions in MM. Therefore, we have evaluated bone anabolic effects of a DKK1 neutralizing antibody (BHQ880) in MM. In vitro BHQ880 increased OB differentiation, neutralized the negative effect of MM cells on osteoblastogenesis, and reduced IL-6 secretion. In a severe combined immunodeficiency (SCID)–hu murine model of human MM, BHQ880 treatment led to a significant increase in OB number, serum human osteocalcin level, and trabecular bone. Although BHQ880 had no direct effect on MM cell growth, it significantly inhibited growth of MM cells in the presence of bone marrow stromal cells (BMSCs) in vitro. This effect was associated with inhibition of BMSC/MM cell adhesion and production of IL-6. In addition, BHQ880 up-regulated β-catenin level while down-regulating nuclear factor-κB (NF-κB) activity in BMSC. Interestingly, we also observed in vivo inhibition of MM cell growth by BHQ880 treatment in the SCID-hu murine model. These results confirm DKK1 as an important therapeutic target in myeloma and provide the rationale for clinical evaluation of BHQ880 to improve bone disease and to inhibit MM growth.

17114 Background: Gemcitabine (GEM) is a deoxycytidine analog that inhibits DNA synthesis. Pemetrexed (ALIMTA, PEM) is a novel antifolate inhibiting multiple enzymes targets, including thymidylate synthase (TS). This study aimed at evaluating the antitumor effects of these antimetabolites against NSCLC and SCLC tumor models. Methods: In vitro growth inhibition (IC50) studies were done by 6-days MTT assays against a panel of 20 NSCLC and 17 SCLC cell lines. In vivo studies used only NSCLC H2122 tumor line, implanted either subcutaneously in athymic nude mice or orthotopically in athymic nude rats. Drugs were given via the ip route at the designated schedules. Results: Against NSCLC and SCLC cell lines, the averaged IC50s of GEM were 0.015 ± 0.008 μM and 0.055 ± 0.04 μM respectively. The corresponding averaged IC50s for PEM were 0.65 ± 0.2 μM and 0.091±0.018 μM respectively. When H2122 tumors reached 50–100mg, mice were treated with 10 daily doses of PEM at 100, 200 and 300 mg/kg, or three doses of GEM every 4 days at 30, 60 and 120 mg/kg. PEM delayed tumor growth by 12 to 18 days, and GEM delayed by 10 to 14 days, relative to vehicle control. Results of three combination regimens with GEM (30 mg/kg) and PEM (100 mg/kg) were: (1) GEM → PEM gave intermediate activities between the two single agents, but was toxic to animals; (2) PEM and GEM given concurrently were more active than single agents alone and delayed tumor growth by 12 days with some toxic side effects; (3) PEM → GEM was better than the single agents alone, and delayed tumor growth by ∼14 days without toxicity. Athymic nude rats bearing orthotopic H2122 tumors given PEM daily at 50, 100 and 200 mg/kg for 21 days had significantly prolonged survival, but not in a dose-dependent manner. PEM at 50 mg/kg was more effective than doses at 100 or 200 mg/kg. GEM was toxic to nude rats due to poor plasma deamination of GEM. Conclusions: In vitro, PEM was more potent against SCLC than NSCLC cell lines, but GEM had similar activities against all lung lines tested. Studies of H2122 xenografts in rodent supported PEM → GEM as the preferred sequence for the combined administration of these two drugs. [Table: see text]

8106 MOR202 is one of MorphoSys’ internal development programs targeting the cell surface antigen CD38 that is found to be expressed on various cell lines derived from B cell, T cell, and myeloid/monocytic tumors. Especially in the indication of multiple myeloma (MM), which remains an incurable malignancy with a median survival of 3–4 years, a strong expression has been reported in the majority of patients’ tumor samples. CD38-specific human antibodies were selected from MorphoSys’ proprietary HuCAL GOLD phage display library by cell panning strategies. A lead candidate (MOR202) was selected from several antibodies recognizing different epitopes on CD38 and subjected to further in vitro and in vivo characterization as follows: MOR202 exhibits an affinity in the low nanomolar range, recognizes CD38 on many cell lines of different cancer origin and most importantly on all primary MM-patient samples in FACS and IHC. The fully human IgG1 MOR202 is able to kill CD38-expressing cell lines and primary MM cells from patients efficiently by ADCC in a concentration-dependent manner, whereas early progenitor cells are not affected as demonstrated by a clonogenic assay. Finally, excellent efficacy could be shown in a SCID-mouse xenograft model, resulting in significantly reduced tumour growth (RPMI8226) and overall survival, which was even superior to bortezomib tested in the same model.

Abstract 1′-acetoxychavicol acetate (ACA) is a component of traditional Asian condiment, obtained from rhizomes of the commonly used ethno-medicinal plant Languas galanga (Zingiberacetate). Recent extensive studies revealed that ACA has potent chemopreventive effects against various tumors. More recently, we have reported that ACA induces apoptosis of myeloid leukemic cells via mitochondrial- and Fas-mediated dual pathway. The transcription factor NF-κB confers significant survival potential in myeloma cells; therefore, it has emerged as a therapeutic target for the treatment of multiple myeloma. Multiple myeloma is an incurable hematological disorders, which has been fatal outcome despite of high dose chemotherapy with stem cell transplantation; therefore, a novel biologically based therapeutic approach is desired. In this study, we investigated the effects of ACA on myeloma cells in vitro and in vivo, and further examined the molecular mechanisms of ACA-induced apoptosis in myeloma cells. ACA dramatically inhibited cellular growth of various human myeloma cell lines (RPMI8226, U266, IM9, and HS-Sultan) as well as freshly isolated myeloma cells from patients, but not normal bone marrow cells, in a dose (0-20 μM)- and time (0-24 h)-dependent manner. Cultivation with 10 μM ACA rapidly increased the population of cells in the G0/G1 phase with a reduction of cells in the S phase, and a strong induction of apoptosis was shown by the appearance of a hypodiploid DNA peak with sub-G1 DNA content 3 h after treatment. Treatment with ACA induced both caspase-3, -9, and caspase-8 activities, suggesting that ACA-induced apoptosis in myeloma cells mediates both mitochondrial- and Fas-dependent pathways. Furthermore, we investigated the effects of ACA on NF-κB activity in myeloma cells, and were able to demonstrate that ACA significantly inhibited serine phosphorylation and degradation of IκBα in a time-dependent manner. ACA rapidly decreased the nuclear expression of NF-κB, but increased the accumulation of cytosol NF-κB in RPMI8226 cells, indicating that ACA inhibits translocation of NF-κB from the cytosol to the nucleus. In addition, we also confirmed the inhibitory effects of ACA on NF-κB activation by ELISA in myeloma cell lines and fresh samples. ACA had a synergistic proapoptotic effect with another NF-κB inhibitor, MG-132 and TLCK. In contrast, NF-κB activator, PMA, dramatically abrogated ACA-induced apoptosis in myeloma cells. These in vitro studies prompted us to examine whether the effects of ACA are equally valid in vivo. To evaluate the effects of ACA in vivo, RPMI8226-transplanted NOD/SCID mice were treated with ACA. Tumor weight decreased in the mice that were injected ACA (mean weight: 0.04±0.06 g in the ACA-treated group vs. 0.63±0.29 g in the control group; p<0.01). During the treatment, ACA-treated mice appeared healthy, and pathological analysis at autopsy revealed no ACA-induced tissue changes in any of the organ, indicating that ACA might be developed as a new potent anti-cancer agent for the management of multiple myeloma. In conclusion, ACA has an inhibitory activity of NF-κB, and induces apoptosis of myeloma cells in vitro and in vivo. Therefore, ACA provides the new biologically based therapy for the treatment of multiple myeloma patients as a novel NF-κB inhibitor.

We tested the in vitro and in vivo antitumor activity of the maytansinoid DM1 (N2′-deacetyl-N2′-(3-mercapto-1-oxopropyl)-maytansine), a potent antimicrotubule agent, covalently linked to the murine monoclonal antibody (mAb) B-B4 targeting syndecan-1 (CD138). We evaluated the in vitro activity of B-B4–DM1 against a panel of CD138+ and CD138- cell lines, as well as CD138+ patient multiple myeloma (MM) cells. Treatment with B-B4–DM1 selectively decreased growth and survival of MM cell lines, patient MM cells, and MM cells adherent to bone marrow stromal cells. We further examined the activity of B-B4–DM1 in 3 human MM models in mice: (1) severe combined immunodeficient (SCID) mice bearing subcutaneous xenografts; (2) SCID mice bearing green fluorescent protein–positive (GFP+) xenografts; and (3) SCID mice implanted with human fetal bone (SCID-hu) and subsequently injected with patient MM cells. Tumor regression and inhibition of tumor growth, improvement in overall survival, and reduction in levels of circulating human paraprotein were observed in mice treated with B-B4–DM1. Although immunohistochemical analysis demonstrates restricted CD138 expression in human tissues, the lack of B-B4 reactivity with mouse tissues precludes evaluation of its toxicity in these models. In conclusion, B-B4–DM1 is a potent anti-MM agent that kills cells in an antigen-dependent manner in vitro and mediates in vivo antitumor activity at doses that are well tolerated, providing the rationale for clinical trials of this immunoconjugate in MM.

AbstractCarfilzomib, a second-generation proteasome inhibitor, has significantly improved the survival rate of multiple myeloma (MM) patients, but its clinical application is still restricted by drug resistance and cardiotoxicity. Here, we identified a novel proteasome inhibitor, D395, and assessed its efficacy in treating MM as well as its cardiotoxicity at the preclinical level. The activities of purified and intracellular proteasomes were measured to determine the effect of D395 on the proteasome. CCK-8 and flow cytometry experiments were designed to evaluate the effects of D395 on cell growth and apoptosis. The effects of D395 and carfilzomib on serum enzyme activity, echocardiography features, cardiomyocyte morphology, and hERG channels were also compared. In our study, D395 was highly cytotoxic to MM cell lines and primary MM cells but not normal cells, and it was well tolerated in vivo. Similar to carfilzomib, D395 inhibited osteoclast differentiation in a dose-dependent manner. In particular, D395 exhibited lower cardiotoxicity than carfilzomib in all experiments. In conclusion, D395 is a novel irreversible proteasome inhibitor that has remarkable anti-MM activity and mild cardiotoxicity in vitro and in vivo.

Abstract Background Cervical cancer is a type of the most common gynecology tumor in women of the whole world. Accumulating data have shown that icariin (ICA), a natural compound, has anti-cancer activity in different cancers, including cervical cancer. The study aimed to reveal the antitumor effects and the possible underlying mechanism of ICA in U14 tumor-bearing mice and SiHa cells. Methods The antitumor effects of ICA were investigated in vivo and in vitro. The expression of TLR4/MyD88/NF-κB and Wnt/β-catenin signaling pathways were evaluated. Results We found that ICA significantly suppressed tumor tissue growth and SiHa cells viability in a dose-dependent manner. Also, ICA enhanced the anti-tumor humoral immunity in vivo. Moreover, ICA significantly improved the composition of the microbiota in mice models. Additionally, the results clarified that ICA significantly inhibited the migration, invasion capacity, and expression levels of TGF-β1, TNF-α, IL-6, IL-17A, IL-10 in SiHa cells. Meanwhile, ICA was revealed to promote the apoptosis of cervical cancer cells by down-regulating Ki67, survivin, Bcl-2, c-Myc, and up-regulating P16, P53, Bax levels in vivo and in vitro. For the part of mechanism exploration, we showed that ICA inhibits the inflammation, proliferation, migration, and invasion, as well as promotes apoptosis and immunity in cervical cancer through impairment of TLR4/MyD88/NF-κB and Wnt/β-catenin pathways. Conclusions Taken together, ICA could be a potential supplementary agent for cervical cancer treatment.

AbstractMyeloma cells produce excessive levels of dickkopf-1 (DKK1), which mediates the inhibition of Wnt signaling in osteoblasts, leading to multiple myeloma (MM) bone disease. Nevertheless, the precise mechanisms underlying DKK1 overexpression in myeloma remain incompletely understood. Herein, we provide evidence that hypoxia promotes DKK1 expression in myeloma cells. Under hypoxic conditions, p38 kinase phosphorylated cAMP-responsive element-binding protein (CREB) and drove its nuclear import to activate DKK1 transcription. In addition, high levels of DKK1 were associated with the presence of focal bone lesions in patients with t(4;14) MM, overexpressing the histone methyltransferase MMSET, which was identified as a downstream target gene of hypoxia-inducible factor (HIF)-1α. Furthermore, we found that CREB could recruit MMSET, leading to the stabilization of HIF-1α protein and the increased dimethylation of histone H3 at lysine 36 on the DKK1 promoter. Knockdown of CREB in myeloma cells alleviated the suppression of osteoblastogenesis by myeloma-secreted DKK1 in vitro. Combined treatment with a CREB inhibitor and the hypoxia-activated prodrug TH-302 (evofosfamide) significantly reduced MM-induced bone destruction in vivo. Taken together, our findings reveal that hypoxia and a cytogenetic abnormality regulate DKK1 expression in myeloma cells, and provide an additional rationale for the development of therapeutic strategies that interrupt DKK1 to cure MM.

C-type allatostatins (C-type ASTs) are a family of structurally related neuropeptides found in a wide range of insects and crustaceans. To date, the C-type allatostatin receptor in crustaceans has not been deorphaned, and little is known about its physiological functions. In this study, we aimed to functionally define a C-type ASTs receptor in the mud crab, Scylla paramamosian. We showed that C-type ASTs receptor can be activated by ScypaAST-C peptide in a dose-independent manner and by ScypaAST-CCC peptide in a dose-dependent manner with an IC50 value of 6.683 nM. Subsequently, in vivo and in vitro experiments were performed to investigate the potential roles of ScypaAST-C and ScypaAST-CCC peptides in the regulation of ecdysone (20E) and methyl farnesoate (MF) biosynthesis. The results indicated that ScypaAST-C inhibited biosynthesis of 20E in the Y-organ, whereas ScypaAST-CCC had no effect on the production of 20E. In addition, qRT-PCR showed that both ScypaAST-C and ScypaAST-CCC significantly decreased the level of expression of the MF biosynthetic enzyme gene in the mandibular organ, suggesting that the two neuropeptides have a negative effect on the MF biosynthesis in mandibular organs. In conclusion, this study provided new insight into the physiological roles of AST-C in inhibiting ecdysone biosynthesis. Furthermore, it was revealed that AST-C family peptides might inhibit MF biosynthesis in crustaceans.

Abstract The therapeutic outcome of glioblastomas (GBMs) is still very poor. Therefore, invention of novel therapeutic methods against GBM cases is considered urgent. The antitumor effects of naturally-derived compounds are attracting attention recently, and therapeutic efficacy of curcumin, a plant-derived compound previously used for multiple purpose, has been indicated in many cancer systems; however, clinical application of curcumin is considered difficult because of its poor bioavailability (under 1 %). Curcumin monoglucuronide (CMG), a water-soluble prodrug of curcumin recently developed for overcoming this weakness, has been demonstrated excellent antitumor effects for several malignancies in vitro and in vivo; therefore, we investigated the effects of CMG against GBM cells. CMG induced cell death of human GBM cells lines (T98G, U251MG, and U87MG) by dose dependent manner by triggering multiple forms of cell death such as apoptosis and perthanatos. Immunoblotting of CMG-treated GBM cell lysates demonstrated activation of multiple cell death signaling. Furthermore, immunodeficiency mice harboring intracerebral U87MG cell xenografts systemically treated by CMG showed significantly prolonged survival compared with control mice. These results suggest CMG would be a novel therapeutic agent against GBM cases.
