چکیده

The expression of proteins of the tumor necrosis factor (TNF) family on erythroblasts was measured during thalidomide treatment in 29 patients with multiple myeloma (MM). A clinical response was observed in 17 patients (58.6%) and haemoglobin concentration increased in 22 patients (75.9%). The expression of FasL, Fas, TNF-related apoptosis-inducing ligand (TRAIL) and TRAIL-R1 on erythroblasts decreased significantly during thalidomide treatment. Additional in vitro studies revealed that the apoptosis of erythroblasts and the expression of FasL, TRAIL, TRAIL-R1 and TRAIL-R2 was lower in cultures with thalidomide than in control cultures. Altogether our results suggest that thalidomide may stimulate erythropoiesis in MM patients by decreasing the expression of TNF-like ligands/receptors on erythroblasts.

Negative regulation of erythroblast maturation by Fas-L(+)/TRAIL(+) highly malignant plasma cells: a major pathogenetic mechanism of anemia in multiple myeloma.

Multiple myeloma (MM) is associated with severe normochromic/normocytic anemia. This study demonstrates that the abnormal up-regulation of apoptogenic receptors, including both Fas ligand (L) and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), by highly malignant myeloma cells is involved in the pathogenesis of the ineffective erythropoiesis and chronic exhaustion of the erythr...

Background and Objective: Pomalidomide - a combination of Lenalidomide and Thalidomide drugs- is one of the newest anticancer drugs. Pomalidomide induces apoptosis in cancer cells. Furthermore, few studies indicating its relatively low cytotoxic effects on normal peripheral blood cells have been carried out. However, there is yet no information about the effects of Pomalidomide on bone marrow c...

Increased death receptor resistance and FLIPshort expression in polycythemia vera erythroid precursor cells.

Polycythemia vera (PV) is a clonal myeloproliferative disorder characterized by excessive erythrocyte production. Most patients with PV harbor an activating JAK2 mutation, but the molecular links between this mutation and erythrocyte overproduction are unknown. The interaction between death receptors and their ligands contributes to the physiological regulation of erythropoiesis through the inh...

A role of TRAIL in killing osteoblasts by myeloma cells.

In multiple myeloma (MM), neoplastic plasma cells accumulate in the bone marrow where their survival, proliferation, and apoptosis are controlled at multiple levels by interaction with the bone marrow microenvironment. Myeloma cells actively control these interactions by activating stromal and endothelial cells for production of survival factors, such as interleukin-6, and suppressing other cel...
