Bone Marrow Microenvironment in Multiple Myeloma Progression
Substantial advances have been made in understanding the biology of multiple myeloma (MM) through the study of the bone marrow (BM) microenvironment. Indeed, the BM niche appears to play an important role in differentiation, migration, proliferation, survival, and drug resistance of the malignant plasma cells. The BM niche is composed of a cellular compartment (stromal cells, osteoblasts, osteo...
متن کاملRole of the hypoxic bone marrow microenvironment in 5T2MM murine myeloma tumor progression.
BACKGROUND AND OBJECTIVES Unlike most other tumors, multiple myeloma (MM) cells have to survive and to grow in a bone marrow (BM) microenvironment which is already hypoxic by nature. BM hypoxia is crucial for normal hematopoiesis. However, how BM hypoxia and MM affect each other is unknown. We addressed this topic in the 5T2MM mouse model. DESIGN AND METHODS Levels of hypoxia in the BM of con...
متن کاملCD38 and bone marrow microenvironment.
This review summarizes the events ruled by CD38 shaping the bone marrow environment, recapitulating old and new aspects derived from the body of knowledge on the molecule. The disease models considered were myeloma and chronic lymphocytic leukemia (CLL). CD38 has been analyzed considering its twin function as receptor and enzyme, roles usually not considered in clinics, where it is used as a ro...
متن کاملTumor microenvironment in cancer progression
Keywords: tumor microenvironment; Heat-shock Factor 1 (HSF1) Billions of years of evolution through changing environments led organisms to develop an arsenal of cytoprotec-tive pathways to promote their survival under stressful conditions. We hypothesized that tumors exploit these mechanisms to support their own survival as they rapidly develop and evolve in a hostile and stressful environment....
متن کاملBone marrow-derived CD13+ cells sustain tumor progression
Non-malignant cells found within neoplastic lesions express alanyl (membrane) aminopeptidase (ANPEP, best known as CD13), and CD13-null mice exhibit limited tumor growth and angiogenesis. We have recently demonstrated that a subset of bone marrow-derived CD11b+CD13+ myeloid cells accumulate within neoplastic lesions in several murine models of transplantable cancer to promote angiogenesis. If t...
