Do CAR-T and Allogeneic Stem Cell Transplant Both Have a Place in Lymphoid Neoplasms?

Allogeneic stem cell transplantation (allo-SCT) represented the first immunotherapy to treat hematologic malignancies: it has been considered as a cure for the disease and never as an approach to extend the life of patients. The success of allo-SCT derives both from the ability to treat patients with intensive chemoradiotherapy and from the potent graft-versus-leukemia effects mediated by donor immunity. Although considerable progress has been made in the last years, significant barriers still remain in the form of disease relapse, graft-versus-host disease, infectious complications, and regimen-related toxicities.

The adipose organ and multiple myeloma: Impact of adipokines on tumor growth and potential sites for therapeutic intervention.

In addition to its capacity to store lipids the adipose tissue is now identified as a real organ with both endocrine and metabolic roles. Preclinical results indicate that modifying adipose tissue and bone marrow adipose tissue (BMAT) could be a successful multiple myeloma (MM) therapy. BMAT interrelates with bone marrow cells and other immune cells, and may influence MM disease progression.

Nanobodies and Cancer: Current Status and New Perspectives.

Reducing the dimension of antigen-binding proteins to an only immunoglobulin domain has been one of the objectives of antibody manufacturing. Heavy chain antibodies were encountered while attempting to separate the blood serum proteins of dromedaries. Later the term "nanobodies" (Nbs) was introduced.

Telomerase and telomere biology in hematological diseases: A new therapeutic target.

Telomeres are structures confined at the ends of eukaryotic chromosomes. With each cell division, telomeric repeats are lost because DNA polymerases are incapable to fully duplicate the very ends of linear chromosomes. Loss of repeats causes cell senescence, and apoptosis.

Anticancer Activity of Curcumin and Its Analogues: Preclinical and Clinical Studies.

Curcumin has been shown to have a wide variety of therapeutic effects, ranging from anti-inflammatory, chemopreventive, anti-proliferative, and anti-metastatic. This review provides an overview of the recent research conducted to overcome the problems with the bioavailability of curcumin, and of the preclinical and clinical studies that have reported success in combinatorial strategies coupling curcumin with other treatments. Research on the signaling pathways that curcumin treatment targets shows that it potently acts on major intracellular components involved in key processes such as genomic modulations, cell invasion and cell death pathways.

Adoptive immunotherapy for hematological malignancies: Current status and new insights in chimeric antigen receptor T cells.

Hematological malignancies frequently express cancer-associated antigens that are shared with normal cells. Such tumor cells elude the host immune system because several T cells targeted against self-antigens are removed during thymic development, and those that persist are eliminated by a regulatory population of T cells. Chimeric antigen receptor-modified T cells (CAR-Ts) have emerged as a novel modality for tumor immunotherapy due to their powerful efficacy against tumor cells.

The metabolomic signature of hematologic malignancies.

The ongoing accumulation of knowledge raises hopes that understanding tumor metabolism will provide new ways for predicting, diagnosing, and even treating cancers. Some metabolic biomarkers are at present routinely utilized to diagnose cancer and metabolic alterations of tumors are being confirmed as therapeutic targets. The growing utilization of metabolomics in clinical research may rapidly turn it into one of the most potent instruments used to detect and fight tumor.

The cancer stem cell hypothesis: a guide to potential molecular targets.

Common cancer theories hold that tumor is an uncontrolled somatic cell proliferation caused by the progressive addition of random mutations in critical genes that control cell growth. Nevertheless, various contradictions related to the mutation theory have been reported previously. These events may be elucidated by the persistence of residual tumor cells, called Cancer Stem Cells (CSCs) responsible for tumorigenesis, tumor maintenance, tumor spread, and tumor relapse.

Effect of therapeutic plasma exchange on plasma levels of oxidative biomarkers in a patient with thrombotic thrombocytopenic purpura.

Background: The role of oxidative stress in the initiation and progression of endothelial damage in thrombotic thrombocytopenic purpura (TTP) syndrome has been the subject of much speculation in the recent past.

Objectives: The aim of this study was to measure the concentration of plasma advanced oxidation protein products (AOPPs), advanced glycation end products (AGEs), and carbonyl groups (CG) as markers of oxidative stress in plasma of a patient with TTP during the course of the disease until recovery and to evaluate the effect of plasmapheresis (PE) on these biomarkers.

Materials And Methods: The study consisted of plasma analysis of the patient, and 23 healthy subjects served as controls.

MiRNome expression is deregulated in the peripheral lymphoid compartment of multiple myeloma.

MicroRNAs (miRNAs) are short non-coding RNAs involved in the regulation of gene expression. Selected groups of miRNAs are differentially expressed in various types of cancers. Alterations in miRNAs gene expression have been shown in cells from the B-cell malignancy, multiple myeloma (MM).

New orally active proteasome inhibitors in multiple myeloma.

Bortezomib is the first proteasome inhibitor approved for the therapy of multiple myeloma (MM). Although Bortezomib has renovated the treatment of MM, a considerable proportion of subjects fail to respond to Bortezomib treatment and almost all patients relapse from this drug either alone or when used in combination therapies. However, the good clinical outcome of Bortezomib treatment in MM patients gave impulsion for the development of second generation proteasome inhibitors with the ambition of improving efficacy of proteasome inhibition, enhancing antitumor activity, and decreasing toxicity, as well as providing flexible dosing schedules and patient convenience.

Evaluation of interleukin-23 plasma levels in patients with polycythemia vera and essential thrombocythemia.

Essential thrombocythemia (ET), polycythemia vera (PV) and myelofibrosis share the same acquired genetic lesion, JAK2V617F. It is believed that cytokines participate in the activation of JAK2V617F. In this study, we analyzed the plasma levels of interleukin (IL)-23, IL-10 and IL-22 in patients with PV and ET.

Circulating microRNAs: new biomarkers in diagnosis, prognosis and treatment of cancer (review).

MicroRNAs (miRNAs) are small non-coding, endogenous, single-stranded RNAs. MiRNAs have been implicated in different areas such as the immune response, neural development, DNA repair, apoptosis, oxidative stress response and cancer. However, while the majority of miRNAs are found intracellularly, a significant number of miRNAs have been observed outside of cells, including various body fluids.

Changes in advanced oxidation protein products, advanced glycation end products, and s-nitrosylated proteins, in patients affected by polycythemia vera and essential thrombocythemia.

Objectives: Oxidative stress has a clear pro tumoral effect in myeloproliferative neoplasms (MPDs). In this study, we analyzed oxidative stress in patients with essential thrombocythemia (ET) and polycythemia vera (PV). Design and methods We analyzed serum levels of advanced oxidation protein products (AOPPs) degradation, advanced glycation end products (AGEs), and protein nitrosylation in ET and PV patients.

Stevens-Johnson syndrome after lenalidomide therapy for multiple myeloma: a case report and a review of treatment options.

Stevens- Johnson syndrome (SJS) is a severe and life-threatening condition. Although allopurinol, an antihyperuricemia drug, is the drug most commonly associated with SJS, more than 100 different causative drugs have been reported. Among hematologic drugs recently introduced into the market, drugs such as rituximab, imatinib, and bortezomib are reported.

Increased serum levels of neutrophil gelatinase-associated lipocalin in patients with essential thrombocythemia and polycythemia vera.

Neutrophil gelatinaase-associated lipocalin (NGAL) is a glycoprotein bound with matrix metalloproteinase-9 (MMP-9) in human neutrophils, and elevated tissue NGAL expression has been documented in different infectious and inflammatory conditions. Recent evidence suggests that NGAL expression is induced in many types of human cancer. Moreover, NGAL is required for BCR-ABL-induced tumorigenesis.

Novel therapeutic strategies in multiple myeloma: role of the heat shock protein inhibitors.

Despite advances in understanding the molecular pathogenesis of multiple myeloma and promising new therapies, almost all patients eventually relapse with resistant disease. There is therefore a strong rationale for combining novel therapies that target intrinsic molecular pathways mediating multiple myeloma cell resistance. One such protein family is the heat shock proteins (HSP), especially the HSP90 family.
