The histone deacetylase inhibitor valproic acid (VPA) has been used for many decades in neurology and psychiatry. The more recent introduction of the histone deacetylase inhibitors (HDIs) belinostat, romidepsin and vorinostat for treatment of hematological malignancies indicates the increasing popularity of these agents. Belinostat, romidepsin and vorinostat are metabolized or transported by polymorphic enzymes or drug transporters. Thus, genotype-directed dosing could improve pharmacotherapy by reducing the risk of toxicities or preventing suboptimal treatment...

Purpose: Mesenchymal Stem Cells (MSCs) are one of the essential members of Bone Marrow (BM) microenvironment and the cells affect normal and malignant cells in BM milieu. One of the most important hematological malignancies is Multiple Myeloma (MM). Numerous studies reported various effects of MSCs on myeloma cells. MSCs initiate various signaling pathways in myeloma cells, particularly NF-kβ. NF-kβ signaling pathway plays pivotal role in the survival, proliferation and resistance of myeloma cells to the anticancer drugs, therefore this pathway can be said to be a vital target for cancer therapy...

Diverse strategies to develop novel treatments for rheumatoid arthritis which specifically target those patients who do not respond to available medications, including biologics, are currently being explored. New potential therapeutic approaches which may become available as part of standard therapeutic regimens include the propagation of regulatory T cells and-in the future-of regulatory B cells. New biologic disease-modifying antirheumatic drugs (b-DMARDs) against interleukin-17 and -6, granulocyte-macrophage colony-stimulating factor, and complement component 5 are now standard components of clinical treatment programs...

While antibody-based therapies have emerged as clinically effective approaches for several hematologic and solid malignancies, they have not played a significant role to date in the treatment of acute myeloid leukemia (AML). More recently, improvements in antibody-drug conjugate technology, bispecific antibodies, as well as identification of novel AML antigens have re-invigorated enthusiasm for antibody-based therapies for AML. This review describes experiences with former and existing antibody-based therapies for AML, including unconjugated antibodies, antibody-drug conjugates (ADCs), radio-labelled antibodies, and immune-engaging antibodies, and discusses the promise and challenges associated with each...

Epigenetic marks, such as histone modifications or DNA methylation, regulate tissue specific gene expression by affecting the structures and accessibility of chromatin or DNA. Epigenetics, the molecular mechanisms regulating the epigenome, would therefore be critically involved in development and cell differentiation versus proliferation. Histone modifications include methylation, acetylation, phosphorylation and ubiquitination of specific lysine, arginine or serine residues on histone tails, and each modification has its own specific effect on gene expressions...

Upconversion nanoparticles (UCNPs), with fascinating optical and chemical features, are a promising new generation of fluorescent probes. Although UCNPs have been widely used in diagnosis and therapy, there is an unmet need for a simple and effective surface engineering method that can produce cancer-targeting UCNPs. Here, we show that by coating particles with macrophage membranes, it becomes possible to utilize the adhesion between macrophages and cancer cells for effective cancer targeting. Natural macrophage membranes along with their associated membrane proteins were reconstructed into vesicles and then coated onto synthetic UCNPs...

Multiple myeloma (MM) is a fatal hematological cancer characterized by clonal plasma cell proliferation in the bone marrow. MM has an increasing global incidence and a poor prognosis. There are limited treatment options available for MM, and this is further compounded by the development of drug resistance. The present study demonstrated that 7-{4-[Bis-(2-hydroxyethyl)-amino]-butoxy}-5-hydroxy-8-methoxy-2-phenylchromen-4-one (V8), a novel synthetic flavonoid, induced apoptosis in human MM RPMI 8226 cells in a dose- and time-dependent manner, using cell viability assays and flow cytometry...

Hodgkin lymphoma (HL) is a highly curable hematologic malignancy, and ~70% of cases can be cured with combination chemotherapy with or without radiation. However, patients with primary resistant disease have a cure rate of <30%. For such patients, high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is considered to be the standard treatment. If patients fail to respond to ASCT or relapse soon thereafter, they usually receive another ASCT, allogeneic stem cell transplantation or treatment with novel agents...

Multiple myeloma is characterized by clonal proliferation of plasma cells within the bone marrow resulting in anemia, lytic bone lesions, hypercalcemia, and renal impairment. Despite advanced in our understanding of this complex disease in recent years, it is still considered an incurable malignancy. This is, in part, due to the highly heterogenous genomic and phenotypic nature of the disease, which is to date incompletely understood. It is clear that a deeper level of knowledge of the biological events underlying the development of these diseases is needed to identify new targets and generate effective novel therapies...

Systemic mastocytosis is a heterogeneous disease characterized by the accumulation of neoplastic mast cells in the bone marrow and other organ organs/tissues. Mutations in KIT, most frequently KIT D816V, are detected in over 80% of all systemic mastocytosis patients. While most systemic mastocytosis patients suffer from an indolent disease variant, some present with more aggressive variants, collectively called "advanced systemic mastocytosis", which include aggressive systemic mastocytosis, systemic mastocytosis with an associated hematologic, clonal non mast cell-lineage disease, and mast cell leukemia...

Even though combining surgery with chemotherapy has significantly improved the prognosis of osteosarcoma patients, advanced, metastatic, or recurrent osteosarcomas are often non-responsive to chemotherapy, making development of novel efficient therapeutic methods an urgent need. Adoptive immunotherapy has the potential to be a useful non-surgical modality for treatment of osteosarcoma. Recently, alternative strategies, including immunotherapies using naturally occurring or genetically modified T cells, have been found to hold promise in the treatment of hematologic malignancies and solid tumors...

Invasive fungal infections (IFI) represent a major hindrance to the success of hematopoietic stem cell transplantation (HSCT), contributing substantially to morbidity and infection-related mortality. During the most recent years several reports indicate an overall increase of IFI among hematologic patients, in particular, invasive aspergillosis, that may be explained, at least partially, by the fact that diagnoses only suspected in the past, are now more easily established due to the application of serum biomarkers and early use of CT scan...

The concept of high-doses chemotherapy was developed in the 1980s based on in vitro scientific observations. Exposure of tumor cells to increasing concentrations of alkylating agents resulted in increased cell death in a strong dose-response manner. Moreover, the acquired resistance of tumor cells could be overcome by dose intensification. In clinic, dose intensification of alkylating agents resulted in increased therapeutic responses, however associated with significant hematological toxicity. Following the development of autologous stem cells transplantation harvesting from peripheral blood, the high-doses of chemotherapy, initially associated with marked toxic effects, could be more easily tolerated...

Nasal-type natural killer/T-cell lymphoma (nasal NKTCL) is an aggressive hematological neoplasm with poor prognosis, and its incidence is higher in Asia than in Western countries. Increasing evidence suggests that aberrant activation of signal transducers and activators of transcription 3 (STAT3) is related to numerous malignancies. However, the involvement of STAT3 in the pathogenesis of nasal NKTCL is poorly understood. In this study, immunohistochemistry (IHC) showed that 21/28 (75.0%) nasal NKTCL tissues harbored constitutively expression of phospho‑STAT3 (p‑STAT3) which was positively correlated with the Ki‑67 levels (P﹤0...

The process of curing a patient by removing his illness by extracting blood is a very old one. Many years ago, phlebotomy was practiced to cure illness. Now, this old process, placed on a rational basis with therapeutic apheresis (TA), is being followed in clinical practice. Therapeutic plasma exchange (TPE) with hollow fiber modules has been used in different severe diseases for more than 40 years. Based on many years of experience with the extracorporeal circulation in end-stage renal disease, the authors herein give an overview of TA in immunological diseases, especially in hematologic, autoimmune and dermatologic diseases...

Importance: Multiple myeloma (MM) is the second most common hematological malignant abnormality. The introduction of immunomodulatory drugs (IMiDs) and proteasome inhibitors (PIs) has greatly improved the overall survival of patients with MM. Prevention and treatment of cardiovascular and thrombotic issues associated with novel MM therapies have emerged as important aspects of supportive care in patients with MM. Observations: We searched PubMed and the Cochrance database for studies published from March 2001 to January 2016...

Isocitrate dehydrogenase 1 and 2 (IDH1 and IDH2) are key metabolic enzymes that convert isocitrate to α-ketoglutarate. IDH1/2 mutations define distinct subsets of cancers, including low-grade gliomas and secondary glioblastomas, chondrosarcomas, intrahepatic cholangiocarcinomas, and hematologic malignancies. Somatic point mutations in IDH1/2 confer a gain-of-function in cancer cells, resulting in the accumulation and secretion in vast excess of an oncometabolite, the D-2-hydroxyglutarate (D-2HG). Overproduction of D-2HG interferes with cellular metabolism and epigenetic regulation, contributing to oncogenesis...

Multiple myeloma (MM) is a disorder of terminally differentiated plasma cells characterized by clonal expansion in the bone marrow (BM). It is the second-most common hematologic malignancy. Despite significant advances in therapeutic strategies, MM remains a predominantly incurable disease emphasizing the need for the development of new treatment regimens. Immunotherapy is a promising treatment modality to circumvent challenges in the management of MM. Many novel immunotherapy strategies, such as adoptive cell therapy and monoclonal antibodies, are currently under investigation in clinical trials, with some already demonstrating a positive impact on patient survival...

Although the treatment options for systemic lupus erythematosus (SLE) have significantly improved over the past years through the introduction of novel targeted biologic therapies, there are still some patients who suffer from refractory and potentially life-threatening courses of the disease. For these patients autologous hematopoietic stem cell transplantation (ASCT) after immunoablative chemotherapy provides a promising treatment option with curative potential. Based on preclinical models, ASCT was first introduced in 1996 and has since been carried out in approximately 300 patients worldwide...

BACKGROUND: Despite the recent development of new therapies, multiple myeloma (MM) remains an incurable disease. Thus, new, effective treatments are urgently needed, particularly for relapsed or refractory MM (RRMM). In an earlier phase I study, a novel form of recombinant human Apo2L/tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) that is currently in clinical development for the treatment of hematologic malignancies, i.e., circularly permuted TRAIL (CPT), was well tolerated at a dose of 2...
