REVIEW

PURPOSE OF REVIEW: Multiple myeloma remains an incurable disease, largely due to the tumor-supportive role of the bone marrow microenvironment. Bone marrow adipose tissue (BMAT) is one component of the fertile microenvironment which is believed to contribute to myeloma progression and drug resistance, as well as participate in a vicious cycle of osteolysis and tumor growth. RECENT FINDINGS: MicroRNAs (miRNAs) have recently emerged as instrumental regulators of cellular processes that enable the development and dissemination of cancer...

Animal and human data suggest statins may be protective against developing multiple myeloma; however, findings may be biased by the interrelationship with lipid levels. We investigated the association between statin use and risk of multiple myeloma in a large US population, with an emphasis on accounting for this potential bias. We conducted a case-control study nested within 6 US integrated healthcare systems participating in the National Cancer Institute-funded Cancer Research Network. Adults aged ≥40 years who were diagnosed with multiple myeloma from 1998-2008 were identified through cancer registries (N=2532)...

Regulation of the ubiquitin-proteasome system (UPS) to treat select types of cancer has become a popular area of drug discovery research. The FDA approval of proteasome inhibitors Bortezomib and Carfilzomib in the treatment of multiple myeloma has led to an increased need for chemical reporters capable of detecting and quantifying protein ubiquitination and the activity of members of the UPS including E3 ubiquitin ligases and the proteasome in the tumor cells of the patients. One limitation of peptide-based reporters is their rapid degradation in the cellular environment by cytosolic peptidases...

BACKGROUND AND OBJECTIVES: Since a study published in 2002 showed a survival advantage of melphalan-only conditioning for stem cell transplantation (HSCT) over melphalan-total body irradiation (mel-TBI) in patients with multiple myeloma (MM), most centers abandoned mel-TBI. Mel-TBI causes more early toxicity and is more complicated to administer, but we speculated it may result in longer term survival with radiation as an independent treatment modality. Therefore, we analyzed the long-term outcome of patients with MM who received mel-TBI as part of conditioning at our center...

AIMS: Some types of monoclonal gammopathies are typified by a very limited availability of aberrant cells. Modern research use high throughput technologies and an integrated approach for detailed characterisation of abnormal cells. This strategy requires relatively high amounts of starting material which cannot be obtained from every diagnosis without causing inconvenience to the patient. The aim of this methodological paper is to reflect our long experience with laboratory work and describe the best protocols for sample collection, sorting and further preprocessing in terms of the available number of cells and intended downstream application in monoclonal gammopathies research...

BACKGROUND/PURPOSE: Typhoid and paratyphoid fever continue to be important causes of illness and death in parts of Asia, being associated with poor sanitation and consumption of unsafe food and water. Antimicrobial resistance has emerged to traditional first-line drugs, namely, the fluoroquinolones, as well as to third-generation cephalosporins, posing challenges to treatment. Azithromycin has proven to be an effective alternative for treatment of uncomplicated typhoid fever. The purpose of this study was to determine the antimicrobial susceptibility, clinical outcome and serotype distribution pattern of clinical isolates belonging to Salmonella enterica subspecies enterica...

BACKGROUND: Multiple myeloma is the second most prevalent hematologic malignancy and thought to be incurable. Therefore, it's urgent to find new drugs for treatment. Some experiments have shown that curcumin might have great potential in treating multiple myeloma, while the mechanism is still unknown. EZH2 and SUZ12 are the core proteins in PRC2 and their expression are increased in various human cancers, including the poor prognostic multiple myeloma. Meanwhile, the regulation of miRNAs and EZH2 has been demonstrated in other cancer researches, like lung cancer, pancreatic cancer, leukemia and so on...

The proteasome-inhibitor bortezomib was introduced into the treatment of multiple myeloma more than a decade ago. It is clinically beneficial, but peripheral neuropathy (PNP) is a side effect that may limit its use in some patients. To examine the possible genetic predisposing factors to PNP, we performed a genome-wide association study on 646 bortezomib-treated German multiple myeloma patients. Our aim was to identify genetic risk variants associated with the development of PNP as a serious side effect of the treatment...

Treatment advances for multiple myeloma (MM) that have prolonged survival emphasise the importance of measuring patients' health-related quality of life (HRQoL) in clinical studies. HRQoL/functioning and symptoms of patients with relapsed/refractory MM (RRMM) receiving second- or third-line lenalidomide or bortezomib treatment were measured in a prospective European multicentre, observational study at different time points. At baseline, patients in the lenalidomide cohort were frailer than in the bortezomib cohort with more rapid disease progression at study entry (more patients with Eastern Cooperative Oncology Group performance status >2, shorter time from diagnosis, more chronic heart failure, higher serum creatinine levels, more patients with dialysis required)...

Thalidomide and its derivatives are immunomodulatory drugs (IMiDs) known for their sedative, teratogenic, anti-angiogenic, and anti-inflammatory properties. Commonly used in the treatment of cancers such as multiple myeloma and myelodysplastic syndrome (MDS), IMiDs have also been used in the treatment of an inflammatory skin pathology associated with Hansen's disease/leprosy. They have also shown promise in the treatment of autoimmune disorders including systemic lupus erythmatosus (SLE) and inflammatory bowel disease (IBD)...

The understanding and treatment of multiple myeloma (MM) have dramatically improved in recent years. However, accurate assessment of the response of myeloma to therapy and its subsequent relapse remains a difficult task. Criteria have changed over time and new parameters have recently been incorporated to evaluate minimal residual disease status. We present a practical approach to assess response and relapse/progression in myeloma in the context of its treatment. A robust reporting schema is crucial to correctly evaluate any treatment protocol and compare results across trials...

We studied 140 families with two or more lymphoid cancers, including non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), chronic lymphocytic leukemia (CLL), and multiple myeloma (MM), for deviation from the population age of onset and lymphoid cancer co-occurrence patterns. Median familial NHL, HL, CLL and MM ages of onset are substantially earlier than comparable population data. NHL, HL and CLL (but not MM) also show earlier age of onset in later generations, known as anticipation. The co-occurrence of lymphoid cancers is significantly different from that expected based on population frequencies (p < ...

OBJECTIVES: Multiple myeloma (MM) primarily strikes older adults, but full-dose chemotherapy such as bortezomib (Velcade), cyclophosphamide and dexamethasone (VCD) is often excessively toxic to very old or frail adults and those with substantial comorbidities. We piloted dose-attenuated VCD ("VCD-Lite") in such vulnerable adults with newly diagnosed MM (NDMM). MATERIALS AND METHODS: Subjects with NDMM and a high risk of therapy-related toxicity due to factors above received bortezomib 1...

Multiple myeloma (MM)is a kind of plasma tumor originated from B cell line. Its incidence ranks in second place of hematopoietic malignancies. Although continued progress was made in treatment of MM,the survival rate and prognosis of MM patients are still not satisfactory. Further understanding of the pathogenesis of MM may provide information to develop new treatment strategies, so as to improve survival rate and ameliorate its prognosis. Many researches have demonstrated that bone marrow microenvironment plays an important role in MM pathogenesis, which regulates the biological properties of MM cells, including migration and proliferation, through miRNA, mRNA and protein contained in the exosomes released from the cells in the tumor microenvironment...

Cancer-testis antigens (CTA) are a class of tumor-associated antigens, which are mainly located in X chromosome. CTA restrictively expressed in normal testis, ovary, placenta and so on. Their expression in other normal tissues is much lower, even can not be detected. However, their expressions are aberrantly high in human cancers. Based on CTA encoding immunogenic proteins, they can be regulated by epigentics, CTA provides very attractive targets for cancer immunotherapy. Multiple myeloma (MM) is incurable and has a low cureative rate and a high relapse rate...

Cell adhesion-mediated drug resistance (CAM-DR) remains the primary obstacle in human multiple myeloma (MM) therapy. In this study, we aimed at investigating the expression and biologic function of ARF1 in MM. We determined that ARF1 expression was positively correlated with cell proliferation and knockdown of ARF1 contributed to CAM-DR. The enhancement in the adhesion of MM cells to fibronectin (FN) or the bone marrow stroma cell line HS-5 cells translated to an increased CAM-DR phenotype. Importantly, we showed that this CAM-DR phenotype was correlated with the phosphorylation of Akt and ERK in MM cells...
