eIF4E is the key regulator of protein translation and critical for translation. The oncogenic potential of tumorigenesis, which is highly contingent on cap-dependent eIF4E, also arises from the critical role in the nuclear export and cytosolic translation of oncogenic transcripts. Inhibition of Exportin1 (XPO1), which is the major nuclear export protein for eIF4E-bound oncoprotein mRNAs, result...
Introduction: Multiple myeloma is characterized by plasma cell infiltration of the bone marrow and presence of a monoclonal protein in plasma and/or the urine. Multiple myeloma with biclonal gammopathy is rare (1%). Case Report: In this report, we describe a case of biclonal multiple myeloma having two M bands on serum protein electrophoresis. He had elevated serum IgG and IgA levels. Ig G and ...
Malignant transformation is a multistep process that may involve dysregulation of oncogenes and tumour suppressor genes, and monoclonal gammopathy of undetermined significance (MGUS) is believed to be a precursor of multiple myeloma. To investigate whether aberrant promoter methylation might be involved in the evolution of MGUS to multiple myeloma, we examined the p16, protein tyrosine phosphat...
Purpose: We study CD38 levels in immunosuppressive CD4+CD25highFoxp3+ regulatory T cells (Treg) and further define immunomodulating effects of a therapeutic CD38 mAb isatuximab/SAR650984 in multiple myeloma.Experimental Design: We evaluated percentages of CD38-expressing subsets in Tregs from normal donors and multiple myeloma patients. Peripheral blood mononuclear cells (PBMC) were then treate...
Despite promising preclinical results with mTOR kinase inhibitors in multiple myeloma, resistance to these drugs may arise via feedback activation loops. This concern is especially true for insulin-like growth factor 1 receptor (IGF1R), because IGF1R signaling is downregulated by multiple AKT and mTOR feedback mechanisms. We have tested this hypothesis in multiple myeloma using the novel select...
Pulmonary involvement with multiple myeloma occurs infrequently and may be difficult to distinguish from more common primary lung tumours, metastatic disease, or other pleural and parenchymal abnormalities. A patient who developed acute respiratory distress syndrome (ARDS) was subsequently found to have multiple myeloma with involvement of lung parenchyma by neoplastic plasma cells. Only one ot...
Purpose: The alkylating agentmelphalan prolongs survival in patients withmultiplemyeloma; however, it is associated with toxicities and development of drug-resistance. Here, we evaluated the efficacy of melphalan-flufenamide (mel-flufen), a novel dipeptide prodrug of melphalan in multiple myeloma. Experimental Design: Multiple myeloma cell lines, primary patient cells, and the human multiple my...
سابقه و هدف: پلاسماسیتوما در گروه سنی بالاتر از 25 سال، میزان بروز 30 در هر صدهزار نفر دارد. این نوع بیماری سه نوع تظاهر بالینی دارد. 1) میلوم مولتیپل 2) پلاسماسیتومای منفرد استخوانی 3) پلاسماسیتومای اکسترامدولری. در این مقاله به معرفی یک خانم مبتلا اقدام گردیده است. معرفی بیمار: بیمار خانم 57 ساله ای بود که یکسال قبل تشخیص میلوم مولتیپل برای ایشان داده شده بود علیرغم شیمی درمانی با دیسترس تن...
Patients with relapsed and refractory multiple myeloma have poor prognosis. A recent analysis of patients with relapsed and refractory multiple myeloma who were refractory to both proteasome inhibitors and immunomodulatory drugs showed the median overall survival of 9 months only. Daratumumab is the first-in-class human monoclonal antibody against CD38 cells which was studied in phase I/II tria...
PURPOSE We investigated the in vitro and in vivo anti-multiple myeloma activity of monoclonal antibody (mAb) 1339, a high-affinity fully humanized anti-interleukin 6 mAb (immunoglobulin G1), alone and in combination with conventional and novel anti-multiple myeloma agents, as well as its effect on bone turnover. EXPERIMENTAL DESIGN We examined the growth inhibitory effect of 1339 against mult...
