Multiple myeloma(MM)is the second most prevalent hematological malignancy.Current MM treatment strategies are hampered by systemic toxicity and suboptimal therapeutic efficacy.This study addressed these limitations through the development of a potent MM-targeting chemotherapy strategy,which capitalized on the high binding affinity of alendronate for hydroxyapatite in the bone matrix and the homologous targeting of myeloma cell membranes,termed T-PB@M.The results from our investigations highlight the considerable bone affinity of T-PB@M,both in vitro and in vivo.Additionally,this material demonstrated a capability for drug release triggered by low pH conditions.Moreover,T-PB@M induced the generation of reactive oxygen species and triggered cell apoptosis through the poly(ADP-ribose)polymerase 1(PARP1)-Caspase-3-B-cell lymphoma-2(Bcl-2)pathway in MM cells.Notably,T-PB@M preferentially targeted bone-involved sites,thereby circumventing systemic toxic side effects and leading to prolonged survival of MM orthotopic mice.Therefore,this designed target-MM nanocarrier presents a promising and potentially effective platform for the precise treatment of MM. 展开更多

Multiple myeloma(MM)is a hematological tumor with high mortality and recurrence rate.Carfilzomib is a new-generation proteasome inhibitor that is used as the first-line therapy for MM.However,the development of drug resistance is a pervasive obstacle to treating MM.Therefore,elucidating the drug resistance mechanisms is conducive to the formulation of novel therapeutic therapies.To elucidate the mechanisms of carfilzomib resistance,we retrieved the GSE78069 microarray dataset containing carfilzomib-resistant LP-1 MM cells and parental MM cells.Differential gene expression analyses revealed major alterations in the major histocompatibility complex(MHC)and cell adhesion molecules.The upregulation of the tumor necrosis factor(TNF)receptor superfamily member 1A(TNFRSF1A)gene was accompanied by the downregulation of MHC genes and cell adhesion molecules.Furthermore,to investigate the roles of these genes,we established a carfilzomib-resistant cell model and observed that carfilzomib resistance induced TNFRSF1A overexpression and TNFRSF1A silencing reversed carfilzomib resistance and reactivated the expression of cell adhesion molecules.Furthermore,TNFRSF1A silencing suppressed the tumorigenesis of MM cells in immunocompetent mice,indicating that TNFRSF1A may lead to carfilzomib resistance by dampening antitumor immunity.Furthermore,our results indicated that TNFRSF1A overexpression conferred carfilzomib resistance in MM cells and suppressed the expression of MHC genes and cell adhesion molecules.The suppression of MHC genes and cell adhesion molecules may impair the interaction between immune cells and cancer cells to impair antitumor immunity.Future studies are warranted to further investigate the signaling pathway underlying the regulatory role of TNFRSF1A in MM cells. 展开更多

Multiple myeloma is a hematological malignancy inwhich clonal plasma cells proliferate and accumulate within the bone marrow. The presence of osteolytic le-sions due to increased osteoclast(OC) activity and sup-pressed osteoblast(OB) function is characteristic of the disease. The bone marrow mesenchymal stromal cells(MSCs) play a critical role in multiple myeloma patho-physiology, greatly promoting the growth, survival, drug resistance and migration of myeloma cells. Here, we specifically discuss on the relative contribution of MSCs to the pathophysiology of osteolytic lesions in light of the current knowledge of the biology of my-eloma bone disease(MBD), together with the reported genomic, functional and gene expression differences between MSCs derived from myeloma patients(pMSCs) and their healthy counterparts(dMSCs). Being MSCs the progenitors of OBs, pMSCs primarily contribute to the pathogenesis of MBD because of their reduced osteogenic potential consequence of multiple OB inhibi-tory factors and direct interactions with myeloma cells in the bone marrow. Importantly, pMSCs also readily contribute to MBD by promoting OC formation and ac-tivity at various levels(i.e., increasing RANKL to OPG expression, augmenting secretion of activin A, uncou-pling ephrinB2-EphB4 signaling, and through augment-ed production of Wnt5a), thus further contributing to OB/OC uncoupling in osteolytic lesions. In this review, we also look over main signaling pathways involved in the osteogenic differentiation of MSCs and/or OB activity, highlighting amenable therapeutic targets; in parallel, the reported activity of bone-anabolic agents(at preclinical or clinical stage) targeting those signaling pathways is commented. 展开更多

This review summarizes the therapeutic strategies and the drugs actually in development for the management of myeloma patients. Multiple myeloma is caused by the expansion of monoclonal plasma cells and secretion of M-protein(immunoglobulins, Bence Jones protein and free light chains). Multiple myeloma still remains an incurable disease with a high incidence rate in the elderly, despite the introduction of several new therapeutic agents(bortezomib, lenalidomide and thalidomide) which have changed its natural history. The high heterogeneity of this disease leads to large differences in clinical responses to treatments. Thus, the choice of the best treatment is a difficult issue. However, the introduction of new drugs has made it possible to achieve high response rates and good quality respons-es with long-term disease control. Interactions between tumor cells and their bone marrow microenvironment play a pivotal role in the development, maintenance, and progression of myeloma, inducing also drug resistance. These knowledges have improved treatment options, leading to the approval of new drugs which not only target the malignant cell itself, but also its microenvironment. These agents are in preclinical/early clinical evaluation and they appear to further improve disease control, but their use is still not approved outside of clinical trials. 展开更多

Multiple myeloma(MM) is a cancer caused by uncontrolled proliferation of antibody-secreting plasma cells in bone marrow, which represents the second most common hematological malignancy. MM is a highly heterogeneous disease and can be classified into a spectrum of subgroups based on their molecular and cytogenetic abnormalities. In the past decade, novel therapies, especially, the first-in-class proteasome inhibitor bortezomib, have been revolutionary for the treatment of MM patients. Despite these remarkable achievements, myeloma remains incurable with a high frequency of patients suffering from a relapse, due to drug resistance. Mutation in the proteasome β5-subunit(PSMB5) was found in a bortezomib-resistant cell line generated via long-term coculture with increasing concentrations of bortezomib in 2008, but their actual implication in drug resistance in the clinic has not been reported until recently. A recent study discovered four resistance-inducing PSMB5 mutations from a relapsed MM patient receiving prolonged bortezomib treatment. Analysis of the dynamic clonal evolution revealed that two subclones existed at the onset of disease, while the other two subclones were induced. Protein structural modeling and functional assays demonstrated that all four mutations impaired the binding of bortezomib to the 20 S proteasome, conferring different degrees of resistance. The authors further demonstrated two potential approaches to overcome drug resistance by using combination therapy for targeting proteolysis machinery independent of the 20 S proteasome. 展开更多

The main aim of antineoplastic treatment is to maximize patient benefit by augmenting the drug accumulation within affected organs and tissues,thus incrementing drug effects and,at the same time,reducing the damage of non-involved tissues to cytotoxic agents.Mesenchymal stromal cells(MSC)represent a group of undifferentiated multipotent cells presenting wide self-renewal features and the capacity to differentiate into an assortment of mesenchymal family cells.During the last year,they have been proposed as natural carriers for the selective release of antitumor drugs to malignant cll,s thus optimizing cytotoxic action on cancer cll,while significantly reducing adverse side efect on healthy cells.MSC chemotherapeutic drug loading and delivery is an encouraging new area of cell therapy for several tumors,especially for those with unsatisfactory prognosis and limited treatment options available.Although some experim ental models have been sucesfuly developed,phase I dinical studies are needed to confirm this potential application of cell therapy,in particular in the case of primary and secondary lung cancers. 展开更多

Multiple myeloma(MM)is a clonal expansion of malignant plasma cells,and comprises approximately 10%of hematologic malignancies.Although various therapeutic agents and strategies,such as immunomodulatory agents,proteasome inhibitors,monoclonal antibodies and hematopoietic stem cell transplantation(HSCT)have been evaluated,MM remains largely incurable.It is therefore important to further explore the risk factors for disease progression,and to design trials aimed at improving the patient outcomes.Previous studies have considered the presence of a gain in 1q21 as a risk factor for a poorer overall survival.Gain of 1q21 is one of the most common chromosomal aberrations in MM,being detected by fluorescence in situ hybridization in 36%to 47%of newly-diagnosed patients,as well as 52%and 62%patients with relapsed MM.Although a series of reports identified 1q21 gain in MM as a significant and independent poor prognostic factor,other studies failed to demonstrate any prognostic value.Thus,the prognostic value of 1q21 gain in MM remains controversial.We reviewed the current knowledge about 1q21 gain and its value for the clinical management of MM. 展开更多

Objective:To find out how to overcome resistance during multiple myeloma(MM) treatment through establishing a multidrug resistant human multiple myeloma cell line and investigating its biological features.Methods:The parent cell line MOLP-2 was exposed to different concentrations of melphalan and a melphalan-resistant cell line MOLP-2/R was identified by continuous stepwise selection.The cell morphology and growth curves were examined.Protein levels of P-gp, MRP and FANCD2 monoubiquitination were checked by Western blotting.The IC50 of melphalan and resistance index(RI) were detected by MTT assay.Results:A melphalan-resistant cell line MOLP-2/R was finally identified.The RI of MOLP-2/R cells to melphalan was 6.03.Besides melphalan it was cross resistant to other chemotherapeutic agents, including ADM, CTX, DDP and VP-16.The multiplication time was postponed(P < 0.05).Studies showed that FANCD2 protein monoubiquitination was enhanced, but the levels of P-gp and MRP expressions in the MOLP-2/R cells were similar with the parent cells.Conclusion:MOLP-2/R cell line may serve as an ideal model for exploring the mechanism of MDR.Over-expression of FANCD2 protein monoubiquitination might contribute to acquired drug resistance in MOLP-2/R cell line. 展开更多

Multiple myeloma(MM)is a type of hematological cancer that occurs when B cells become malignant.Various drugs such as proteasome inhibitors,immunomodulators,and compounds that cause DNA damage can be used in the treatment of MM.Autophagy,a type 2 cell death mechanism,plays a crucial role in determining the fate of B cells,either promoting their survival or inducing cell death.Therefore,autophagy can either facilitate the progression or hinder the treatment of MM disease.In this review,autophagy mechanisms that may be effective in MM cells were covered and evaluated within the contexts of unfolded protein response(UPR),bone marrow microenvironment(BMME),drug resistance,hypoxia,DNA repair and transcriptional regulation,and apoptosis.The genes that are effective in each mechanism and research efforts on this subject were discussed in detail.Signaling pathways targeted by new drugs to benefit from autophagy in MM disease were covered.The efficacy of drugs that regulate autophagy in MM was examined,and clinical trials on this subject were included.Consequently,among the autophagy mechanisms that are effective in MM,the most suitable ones to be used in the treatment were expressed.The importance of 3D models and microfluidic systems for the discovery of new drugs for autophagy and personalized treatment was emphasized.Ultimately,this review aims to provide a comprehensive overview of MM disease,encompassing autophagy mechanisms,drugs,clinical studies,and further studies. 展开更多

目的探讨蛋白磷酸酶2调节亚基B′γ(protein phosphatase 2 regulatory subunit B′gamma,PPP2R5C)对多发性骨髓瘤(multiple myeloma,MM)细胞增殖、凋亡和药物敏感性的影响。方法利用qRT-PCR和Western blot检测PPP2R5C在人MM细胞系(MM1S... 目的探讨蛋白磷酸酶2调节亚基B′γ(protein phosphatase 2 regulatory subunit B′gamma,PPP2R5C)对多发性骨髓瘤(multiple myeloma,MM)细胞增殖、凋亡和药物敏感性的影响。方法利用qRT-PCR和Western blot检测PPP2R5C在人MM细胞系(MM1S、RPMI-8226细胞系)和正常外周血单个核细胞(peripheral blood mononuclear cells,PBMC)中的表达水平。在MM1S细胞中分别转染PPP2R5C干扰siRNA(si-PPP2R5C组)及其阴性对照-siRNA(si-CTRL组)、PPP2R5C过表达质粒(OE-PPP2R5C组)及其阴性对照(OE-CTRL组),利用CCK-8法检测各组细胞的增殖能力,流式细胞术检测细胞凋亡情况。用不同浓度硼替佐米(bortezomib,BTZ)处理si-PPP2R5C组和si-CTRL组细胞24 h后,采用CCK-8法检测细胞活力并计算半数抑制浓度(half maximal inhibitory concentration,IC50)。用1 nmol/L的BTZ干预si-PPP2R5C组和si-CTRL组细胞24 h后,采用qRT-PCR和Western blot检测各组细胞中BCL-2和BAX的表达水平,Caspase 3/7活性检测试剂盒检测Caspase 3/7活性,流式细胞术检测细胞凋亡情况。结果相较于PBMC细胞,MM1S、RPMI-8226细胞在mRNA和蛋白水平上均高表达PPP2R5C(均P<0.001)。与si-CTRL组相比,si-PPP2R5C组在培养48 h、72 h后细胞增殖活力均受到抑制(均P<0.001),凋亡率明显增加(5.97%vs 14.39%,P<0.001)。与OE-CTRL组相比,OE-PPP2R5C组在培养48 h、72 h后细胞增殖活力均增强(均P<0.01)。si-PPP2R5C组BTZ的IC50值相比si-CTRL组显著下降(3.40 nmol/L vs 10.37 nmol/L,P<0.001)。si-PPP2R5C+BTZ组相比于Control组和si-CTRL+BTZ组,BCL-2的mRNA和蛋白水平均下降,而BAX的mRNA及蛋白水平、Caspase3/7活性和细胞凋亡率则增加(均P<0.05)。结论PPP2R5C在MM细胞系中显著高表达,敲低PPP2R5C表达后可抑制MM细胞增殖并促进凋亡,以及增强BTZ的药物敏感性。 展开更多
