The Antihelminthic Drug, Mebendazole, Induces Apoptosis in Adult T-Cell Leukemia/Lymphoma Cancer Cells: In-Vitro Trial.

ABSTRACT: Background: Adult T-cell leukemia/lymphoma (ATLL) is a poor prognostic Hematopoietic malignancy with various therapeutic challenges, which had been classified as non-Hodgkin lymphoma. The Drug switching, as a novel, innovative and promising approach, is an opportunity to overcoming on therapeutic challenges of hard-treating disease, e.g. ATLL. Our aim is evaluating the antiproliferative and apoptotic effect of Mebendazole (MBZ) on ATLL cancer cells in in-vitro conditions. Materials and Methods: We used Jurkat cell-line as ATLL cancer cells. After treatment of MBZ in different concentrations on jurkat cells, the cell viabilities were determined by MTT assay. After IC₅₀ value determination, the 24-, 48- and 72-h treatments had been performed in IC₅₀ concentration and control to evaluating the quantitative apoptosis rate by Annexin/PI Flowcytometry and qualitative apoptosis by DAPI Nuclear staining. Also, Glucose spectrophotometry were performed to evaluate the reduced amount of glucose uptake through MBZ treatment. Results: MBZ inhibits proliferation of jurkat cells and IC₅₀ value had been estimated 10 ?M (P< 0.01). According to the flowcytometric results, increasing in drug concentration is associated with decrease cell viability and the percentage of full-apoptosis. However, it inversely correlates with percentage of early-apoptosis rate. Also, the microscopic captures of DAPI Nuclear staining confirms the flowcytometry results in qualitative manner. In addition, it was found that inhibition of glucose uptake was inversely correlated with increased MBZ concentration (P< 0.05). Conclusion: MBZ potentially inhibits the proliferation of ATLL cancer cells in in-vitro condition. MBZ inhibits the growth of Jurkat cells by inducing apoptosis. Also, we suggest that indirectly inhibition of Glucose transporting occurs by MBZ, which could induce apoptosis in cancer cells.

Project description:Uveal melanoma (UM) is a lethal intraocular malignancy with an average survival of only 2~8 months in patients with hepatic metastasis. Currently, there is no effective therapy for metastatic UM. Here, we reported that niclosamide, an effective repellence of tapeworm that has been approved for use in patients for approximately 50 years, exhibited strong antitumor activity in UM cells in vitro and in vivo. We showed that niclosamide potently inhibited UM cell proliferation, induced apoptosis and reduced migration and invasion. p-Niclosamide, a water-soluble niclosamide, exerted potent in vivo antitumor activity in a UM xenograft mouse model. Mechanistically, niclosamide abrogated the activation of the NF-κB pathway induced by tumor necrosis factor α (TNFα) in UM cells, while niclosamide elevated the levels of intracellullar and mitochondrial reactive oxygen species (ROS) in UM cells. Quenching ROS by N-acetylcysteine (NAC) weakened the ability of niclosamide-mediated apoptosis. Matrix metalloproteinase 9 (MMP-9) knockdown by shRNA potentiated, while ectopic expression of MMP-9 rescued, the niclosamide-attenuated invasion, implying that MMP-9 is pivotal for invasion blockage by niclosamide in UM cells. Furthermore, our results showed that niclosamide eliminated cancer stem-like cells (CSCs) as reflected by a decrease in the Aldefluor+ percentage and serial re-plating melanosphere formation, and these phenotypes were associated with the suppressed Wnt/β-catenin pathway by niclosamide in UM. Niclosamide caused a dose- and time-dependent reduction of β-catenin and the key components [e.g., DVLs, phospho-GSK3β (S9), c-Myc and Cyclin D1] in the canonical Wnt/β-catenin pathway. Additionally, niclosamide treatment in UM cells reduced ATP and cAMP contents, and decreased PKA-dependent phosphorylation of β-catenin at S552 and S675 which determine the stability of β-catenin protein, suggesting that niclosamide may work as a mitochondrial un-coupler. Taken together, our results shed light on the mechanism of antitumor action of niclosamide and warrant clinical trial for treatment of UM patients.

Project description:Adult T cell leukemia-lymphoma (ATL) is an aggressive malignancy secondary to chronic infection with the human T cell leukemia virus type I (HTLV-I) retrovirus. ATL carries a dismal prognosis. ATL classifies into four subtypes (acute, lymphoma, chronic, and smoldering) which display different clinical features, prognosis and response to therapy, hence requiring different clinical management. Smoldering and chronic subtypes respond well to antiretroviral therapy using the combination of zidovudine (AZT) and interferon-alpha (IFN) with a significant prolongation of survival. Conversely, the watch and wait strategy or chemotherapy for these indolent subtypes allies with a poor long-term outcome. Acute ATL is associated with chemo-resistance and dismal prognosis. Lymphoma subtypes respond better to intensive chemotherapy but survival remains poor. Allogeneic hematopoietic stem cell transplantation (HSCT) results in long-term survival in roughly one third of transplanted patients but only a small percentage of patients can make it to transplant. Overall, current treatments of aggressive ATL are not satisfactory. Prognosis of refractory or relapsed patients is dismal with some encouraging results when using lenalidomide or mogamulizumab. To overcome resistance and prevent relapse, preclinical or pilot clinical studies using targeted therapies such as arsenic/IFN, monoclonal antibodies, epigenetic therapies are promising but warrant further clinical investigation. Anti-ATL vaccines including Tax peptide-pulsed dendritic cells, induced Tax-specific CTL responses in ATL patients. Finally, based on the progress in understanding the pathophysiology of ATL, and the risk-adapted treatment approaches to different ATL subtypes, treatment strategies of ATL should take into account the host immune responses and the host microenvironment including HTLV-1 infected non-malignant cells. Herein, we will provide a summary of novel treatments of ATL in vitro, in vivo, and in early clinical trials.
