Abstract

Although osteolysis is a common complication in patients with multiple myeloma (MM), the biologic mechanisms involved in the pathogenesis of MM-induced bone disease are poorly understood. Two factors produced by stromal-osteoblastic cells seem critical to the regulation of bone resorption: osteoprotegerin (OPG) and its ligand (OPGL). OPGL stimulates osteoclast differentiation and activity, whereas OPG inhibits these processes. The present study investigated whether myeloma cells affect physiologic OPG/OPGL balance in the bone marrow (BM) environment. Ten human myeloma cell lines and myeloma cells isolated from 26 consecutive patients with MM failed to express OPGL and only rarely produced a low amount of OPG. In a coculture system, human myeloma cells up-regulated OPGL expression but strongly down-regulated OPG production in preosteoblastic (preOB) or stromal cells (BMSCs) of primary human BM at the mRNA and protein levels. This effect, which was dependent on cell-to-cell contact between myeloma cells and BMSCs or preOB, partially involved the integrin VLA-4. In addition, overexpression of OPGL mRNA occurred in ex vivo BM cultures obtained from MM patients as compared with healthy donors, and immunohistochemical staining performed on BM biopsy specimens showed an increase of OPGL and a reduction of OPG expression in MM patients as compared with healthy subjects. In summary, these data indicate that myeloma cells affect the OPG/OPGL ratio in the BM environment and tend to confirm that the OPG/OPGL system is involved in the pathogenesis of MM-induced bone disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
