The importance of the tumor microenvironment in chronic lymphocytic leukemia is widely accepted. Nevertheless, the understanding of the complex interplay between the various types of bystander cells and chronic lymphocytic leukemia cells is incomplete. Numerous studies have indicated that bystander cells provide chronic lymphocytic leukemia-supportive functions, but it has also become clear tha...

apoptosis, or active cell death, is a specific mode of cell death, which is characterized by morphological changes such as chromatin condensation, fragmentation of the nucleus, cytoplasmic retraction and appearance of apoptotic bodies' containing apparently intact organelles. apoptosis occurs in physiological conditions as a regulatory mechanism of tissue growth, where cell proliferation is bal...

background: the ectopic expression of receptor tyrosine kinase ror1 has been reported in patients with hematological malignancies such as chronic lymphocytic leukemia and acute lymphoblastic leukemia. here we report, for the first time, expression of ror1 gene in both tumor tissues and peripheral blood mononuclear cells (pbmc) from patients with renal cancer (rc). methods: in the current study,...

Introduction: Chronic myeloid leukemia (CML) is a malignant clonal disorder of hematopoietic stem cells resulting in the increase of myeloid cells, erythroid cells and platelets in the peripheral blood and hyperplasia in bone marrow. The research evaluated the cytotoxic effects of hydro-alcoholic extracts of Lepidium Sativum (Cress plant) shoots before and after flowering on K562 cell line as a...

Antitumor drug treatment of hemoblastoses always takes into account the patient comorbidity. Due to frequent cardiovascular pathology and atherosclerosis, patients have take statins along with antitumor treatment. Experimental studies shown that inhibit cholesterol synthesis (necessary for vital activity malignant cells), isoprenylation RAS RHO oncogenes, proliferation leukemic cells. In additi...

chronic myelogenous leukemia (cml) is a stem cell disorder sometimes associated with lymphoproliferative disorders. cml may precede a lymphoproliferative disorder. there are a few reports showing associating of cml with multiple myeloma and we report a known cml case that transformed into a full-blown multiple myeloma. this patient had more than 69% of infiltrating myeloma cells in her bone mar...

Nonhuman primate antisera defining leukemia-associ ated and normal Tand B-lymphocyte-associated anti gens were used to characterize serologically the cells from acute myelomonocytic leukemia (AMML) and chronic myelogenous leukemia patients in blast crisis (CML-BC). Earlier studies demonstrated that nonhuman primate an tisera to chronic lymphocytic leukemia, acute myelogen ous leukemia, and chro...

down's syndrome (ds) is the most common chromosomal abnormality in human. subjects with ds are known to be peridisposed to develop leukemia. the molecular basis of the association between ds and leukemia is unknown. the unscheduled dna synthesis (uds) test measure the ability of dna-repair in mammalian cells after excision of a stretch of dna containing the region of damage induced by chem...
