Bone marrow niche-derived extracellular matrix-degrading enzymes influence the progression of B-cell acute lymphoblastic leukemia

Abstract: Specific and reciprocal interactions with the bone marrow microenvironment (BMM) govern the course of hematological malignancies. Matrix metalloproteinase-9 (MMP-9), secreted by leukemia cells, facilitates tumor progression via remodeling of the extracellular matrix (ECM) of the BMM. Hypothesizing that leukemias may instruct the BMM to degrade the ECM, we show, that MMP-9-deficiency in the BMM prolongs survival of mice with BCR-ABL1-induced B-cell acute lymphoblastic leukemia (B-ALL) compared with controls and… Show more

“…Blasts may affect the osteoblastic niche, leading to the loss of osteoblastic cells and an impaired function of normal HSCs [ 60 ]. They contribute to the remodeling of the extracellular matrix (ECM) through secretion of matrix metalloproteinase-9 (MMP-9) [ 66 ]. Interestingly, overexpression of C-X-C chemokine receptor type 4 (CXCR4) on leukemic cells is associated with extra-medullary organs involvement and poor patients’ outcome [ 67 ].…”

“…Together with IL-7, CXCL12 stimulates proliferation of both T- and BCP-ALL [ 73 , 74 ]. Other cytokines (IL-1, IFN-γ, and TNF-α) and the soluble HLA-G in the bone marrow microenvironment may also contribute to T-ALL recurrence by inducing immunotolerance [ 66 , 75 ]. Recently, tunneling nanotubes were identified as a mechanism of the crosstalk between ALL cells and MSCs within the niche.…”

“…Consistently, matrix metalloproteinase-9 (MMP-9) produced by leukemia cells facilitated tumor progression via remodeling of the ECM of the BM microenvironment. This is supported by the fact that MMP-9-deficiency in the BM microenvironment reduced leukemia-initiating cells and prolonged survival of mice with BCR-ABL1-positive B-cell acute lymphoblastic leukemia (B-ALL; Verma et al, 2020 ).…”

“…Similarly, LTβR deficiency reduced the number of leukemic stem cells and prolonged their survival in a murine model of chronic myeloid leukemia, supporting the idea that LTβR signaling in hematopoietic and leukemic stem cells mediates similar effects. Interestingly, leukemic-cell-derived TNF induced matrix metalloproteinase 9 (MMP-9) expression by the bone marrow microenvironment through TNFR1, thus contributing to acute lymphoblastic B-cell leukemia progression [ 34 ]. LTβR signaling may also modulate the leukemic microenvironment: inactivation of LTβR results in a significant delay in leukemia onset in TEL-JAK2 mice, which spontaneously develop T-cell leukemia, presumably due to the loss of LTβR signaling in thymic stromal cells [ 99 ].…”
