LGR4 promotes proliferation and homing via activation of the NF‑κB signaling pathway in multiple myeloma.

ABSTRACT: Multiple myeloma (MM) is a plasma cell malignancy characterized by clonal proliferation in the bone marrow (BM). Previously, it was reported that G‑protein‑coupled receptor 4 (LGR4) contributed to early hematopoiesis and was associated with poor prognosis in patients with MM. However, the mechanism of cell homing and migration, which is critical for MM progression, remains unclear. In the present study, cell counting, cell cycle and BrdU assays were performed to evaluate cell proliferation. Transwell assay and Xenograft mouse models were performed to evaluate cell migration and homing ability both in vitro and in vivo. I was found that overexpression of LGR4 promotes MM cell adhesion, migration and homing to BM both in vitro, while exacerbating osteolytic bone destruct
