For the past few years more and more new cytotoxic agents active in the treatment of hematological malignancies have been synthesized and become available for either in vitro studies or clinical trials. Among them the class of antineoplastic drugs belonging to the purine nucleoside analogues group (PNAs) plays an important role. Three of them: pentostatin(More)
BACKGROUND Chronic lymphocytic leukemia (CLL) primarily affects older persons who often have coexisting conditions in addition to disease-related immunosuppression and myelosuppression. We conducted an international, open-label, randomized phase 3 trial to compare two oral agents, ibrutinib and chlorambucil, in previously untreated older patients with CLL(More)
We investigated the serum concentration of vascular endothelial growth factor (VEGF) and its two soluble receptors, sVEGFR-1 and sVEGFR-2, in a group of 60 patients with systemic lupus erythematosus (SLE), and 20 healthy controls, using an enzyme-linked immunosorbent assay. We examined a possible association between serum levels of these proteins and(More)
We investigated the serum concentrations of interleukin-6 (IL-6) and two IL-6 family of cytokines (leukaemia inhibitory factor (LIF) and ciliary neurotrophic factor (CNTF) as well as IL-6 soluble receptor (sIL-6R) using an enzyme-linked immunosorbent assay (ELISA) in 66 patients with rheumatoid arthritis (RA) and 24 healthy controls. We examined a possible(More)
The mammalian target of rapamycin (mTOR) is a kinase responsible for mitogen-induced cell proliferation/survival signaling. Its activation in response to mitogens leads to a cell-cycle progression from G1 to S phase. mTOR controls the activation of ribosomal protein translation and the initiation of cap-dependent translation. A role of mTOR signaling(More)
BACKGROUND Treatment for patients with chronic lymphocytic leukaemia who are elderly or who have comorbidities is challenging because fludarabine-based chemoimmunotherapies are mostly not suitable. Chlorambucil remains the standard of care in many countries. We aimed to investigate whether the addition of ofatumumab to chlorambucil could lead to better(More)
Functional single nucleotide polymorphism (SNP) C3435T in exon 26 of the MDR1 ( ABCB1 ) gene encoding the xenobiotic transporter P-glycoprotein (P-gp, MDR1, ABCB1) may influence susceptibility to several diseases as well as clinical outcome of treatment with P-gp substrates. Exposure to environmental chemicals is thought to be involved in the pathogenesis(More)
P-glycoprotein (P-gp), the protein product of MDR1 gene, is an important factor regulating the bioavailability of many therapeutics. Recently, the C3435T polymorphism of MDR1 was correlated to altered expression and function of P-gp in normal tissues. In this study, polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay was(More)
Human Tgammadelta lymphocytes constitute from 1 to 15% of all peripheral blood lymphocytes. Recent work has demonstrated that this population plays a major role in the pathogenesis of infectious and immune diseases. Increased numbers of gammadelta T cells have been found in affected skin from systemic sclerosis and chronic cutaneous lupus erythematosus(More)
The study was performed in order to clarify whether granulocyte-macrophage colony stimulating factor (GM-CSF) and granulocyte colony stimulating factor (G-CSF) affect melatonin production and release. We have found that both factors (GM-CSF at doses of 10.0 and 100.0 micrograms/kg, and G-CSF at doses of 1.0, 10.0, and 100.0 micrograms/kg) stimulate(More)
