Abstract
Multiple myeloma (MM) is a hematologic cancer characterized by uncontrolled growth of malignant plasma cells in the bone marrow and currently is incurable. The bone marrow microenvironment plays a critical role in MM. MM cells reside in specialized niches where they interact with multiple marrow cell types, transforming the bone/bone marrow compartment into an ideal microenvironment for the migration, proliferation, and survival of MM cells. In addition, MM cells interact with bone cells to stimulate bone destruction and promote the development of bone lesions that rarely heal. In this review, we discuss how Notch signals facilitate the communication between adjacent MM cells and between MM cells and bone/bone marrow cells and shape the microenvironment to favor MM progression and bone disease. We also address the potential and therapeutic approaches used to target Notch signaling in MM.

Abstract
PURPOSE This study aimed to explore the effect of GANT61 on regulating cell proliferation, cell apoptosis and cell cycle, and to investigate whether GANT61 would function in multiple myeloma (MM) via inhibiting Notch pathway. Methods: RPMI-8226 and U266 cells were treated by GANT61 (0, 2.5, 5.0, 10.0, 20.0, 30.0, 40.0, 50.0 μmol/L) for 18, 24 and 36 hours (h), and cell proliferation was detected by Cell Counting Kit 8. Then these cells were treated by GANT61 at 0, 2.5, 5.0, 10.0 μmol/L for 24 h or treated by 10.0 μmol/L GANT61 for 0, 18, 24 and 36 h, and cell apoptosis rate, apoptosis markers and cell cycle were detected by AV/PI, Western blot, and PI staining. Notch1, Jagged1, Jagged2 and Hes1 expressions were detected by qPCR and Western blot. Further rescue experiments were conducted by upregulating Notch1. Results: In RPMI-8226 and U266 cells, GANT61 inhibited cell proliferation, increased cell apoptosis rate and cell percentage of G1/G0 phase while decreased cell percentage of S phase in a dose- and time-dependent manner. Besides, GANT61 inhibited Notch1, Jagged1, Jagged2 and Hes1 expressions in a dose- and time-dependent manner as well. In rescue experiments, Notch1 upregulation attenuated the inhibition of cell proliferation, promotion of cell apoptosis, induction of G1/G0 cycle retardation and repression of Notch signaling pathway induced by GANT61 treatment in RPMI-8226 and U266 cells. Conclusions: GANT61 suppresses cell proliferation, promotes cell apoptosis and induces G1/G0 cycle retardation with a dose- and time-dependent manner through inhibiting Notch pathway in MM.

Abstract
Purpose The Notch signaling pathway plays an oncogenic role in tongue squamous cell carcinoma. The aim of this study was to inhibit the proliferation and self-renewal of tongue cancer cells by applying Notch signaling pathway inhibitor FLI-06 (Selleck, USA) and to lay a foundation for the clinically targeted treatment of tongue cancer for the future. Methods The mRNA expression level of Notch1 and the overall survival rate of patients with tongue cancer were examined by analyzing the TCGA database. Tongue cancer cells were treated with FLI-06. Cell proliferation, apoptosis, and stem cell self-renewal ability were tested in appropriate ways. A xenograft mouse model was established to observe tumor growth. Results From the TCGA data, we demonstrated that patients with high expression of Notch1 had a poor prognosis. We observed that the Notch signaling pathway inhibitor FLI-06 can restrain the activation of the Notch signaling pathway, decrease cell proliferation and induce cell apoptosis in vitro. The xenograft experiment indicated that intraperitoneal injection of FLI-06 inhibited tumor growth and increased cell apoptosis. FLI-06 suppressed both the mRNA and protein expression of Notch receptor and Notch targeted genes. We also observed that FLI-06 suppressed the proliferation of tongue cancer stem cells. Conclusion FLI-06 can block the proliferation and self-renewal of tongue cancer cells. It is inferred that this compound, which inhibits the Notch signaling pathway, may serve as a potential targeted drug for the treatment of tongue cancer in the clinic.

Abstract
BACKGROUND miR-886-5p plays an important role in many tumors, but it has been rarely investigated in multiple myeloma (MM). We studied the expression of miR-886-5p in the plasma of MM patients and in MM cell lines, and evaluated its biological function to identify its potential involvement in MM. METHODS We recruited 16 subjects including 10 newly diagnosed MM patients who had not received treatment and 6 healthy individuals. The expression of miR-886-5p in plasma and MM cell lines was examined by quantitative reverse transcription polymerase chain reaction. Cell Counting Kit-8, colony formation assay, and 7-amino-actinomycin D/allophycocyanin double staining were performed to detect the function of miR-886-5p in MM cell lines. The expression of Bax and p53 was determined by western blot. RESULTS The expression of miR-886-5p in the plasma of MM patients was higher than that in normal individuals and its level in MM cell lines was higher than that in peripheral blood mononuclear cells isolated from healthy individuals. miR-886-5p could trigger the cell proliferation and inhibition of apoptosis and affect the cell cycle. CONCLUSION miR-886-5p triggered MM cell growth and may act as a diagnostic plasma biomarker for MM, potentially contributing to resistance to chemotherapy.

Abstract
Forkhead box protein 3 (FOXP3) transcription factor is expressed by immune cells and several human cancers and is associated with tumor aggressiveness and unfavorable clinical outcomes. NOTCH and transforming growth factor-β (TGF-β) protumorigenic effects are mediated by FOXP3 expression in several cancer models; however, their interaction and role in melanoma is unknown. We investigated TGF-β-induced FOXP3 gene expression during NOTCH1 signaling inactivation. Primary (WM35) and metastatic melanoma (A375 and A2058) cell lines and normal melanocytes (NHEM) were used. FOXP3 subcellular distribution was evaluated by immuno cytochemical analysis. Gene expression levels were assessed by reverse transcription-quantitative polymerase chain reaction. Protein levels were assessed by western blot analysis. The γ-secretase inhibitor (GSI) was used for NOTCH1 inhibition and recombinant human (rh)TGF-β was used for melanoma cell stimulation. Cell proliferation and viability were respectively assessed by MTT and Trypan blue dye assays. FOXP3 mRNA and protein levels were progressively higher in WM35, A375 and A2058 cell lines compared to NHEM and their levels were further increased after stimulation with rh-TGF-β. TGF-β-mediated FOXP3 expression was mediated by NOTCH1 signaling. Inhibition of NOTCH1 with concomitant rh-TGF-β stimulation determined the reduction in gene expression and protein level of FOXP3. Finally, melanoma cell line proliferation and viability were reduced by NOTCH1 inhibition. The results show that nn increase in FOXP3 expression in metastatic melanoma cell lines is a potential marker of tumor aggressiveness and metastasis. NOTCH1 is a central mediator of TGF-β-mediated FOXP3 expression and NOTCH1 inhibition produces a significant reduction of melanoma cell proliferation and viability.

Abstract
We previously demonstrated that expression of Notch-1 is associated with poor prognosis in lung adenocarcinoma (LAD) patients. The aim of this study is to reveal whether Notch-1 was associated with Taxanes-resistant LAD and, the underlying mechanisms. We collected 39 patients of advanced LAD treated with Taxanes and found that positive Notch-1 expression is closely related to LAD lymph node metastasis, recurrence and poorer prognosis, and Notch-1 acts as an independent poor prognostic factor in LAD by multivariate analysis with Cox regression model. Then, by using the Docetaxel (DTX)-resistant LAD cell lines that we established previously, we found that Notch-1 contributes to resistance of LAD cells to DTX in vitro, and inhibition of Notch-1 sensitizes LAD to DTX in vivo. We further demonstrated that Notch-1 mediates chemoresistance response and strengthens proliferation capacity in LAD cells partially through negative regulation of miR-451 by transcription factor AP-1. Moreover, we found that MDR-1 is a direct target of miR-451 and influences chemoresistance of LAD cells. Taken together, our data revealed a novel Notch-1/AP-1/miR-451/MDR-1 signaling axis, and suggested a new therapeutic strategy of combining DTX with Notch inhibitors to treat DTX-resistant LAD.

Abstract
BACKGROUND Notch may behave as an oncogene or a tumor suppressor gene in lung cancer cells. Notch receptor undergoes cleavage by enzymes, including γ-secretase, generating the active Notch intracellular domain (NICD). The aim of the present study was to investigate the effect of DAPT, a γ-secretase inhibitor, in non-small cell lung cancer (NSCLC) cells, as well as the impact of epidermal growth factor (EGF) that is over-expressed by NSCLC cells, on Notch signaling. H23, A549, H661 and HCC827 human NSCLC cell lines were used, expressing various NICD and EGF receptor (EGFR) protein levels. RESULTS DAPT decreased the number of H661 cells in a concentration-dependent manner, while it had a small effect on H23 and A549 cells and no effect on HCC827 cells that carry mutated EGFR. Notch inhibition did not affect the stimulatory effect of EGF on cell proliferation, while EGF prevented DAPT-induced NICD decrease in H23 and H661 cells. The type of cell death induced by DAPT seems to depend on the cell type. CONCLUSIONS Our data indicate that inhibition of Notch cleavage may not affect cell number in the presence of EGFR mutations and that EGFR may affect Notch signalling suggesting that a dual inhibition of these pathways might be promising in NSCLC.
