    Abstract
    Background
    Multiple myeloma is still incurable and characterized by clonal expansion of plasma cells in the bone marrow. Therefore, effective therapeutic interventions must target both myeloma cells and the BM niche.
    Methods
    Cell proliferation, drug resistance, and chromosomal instability induced by CHEK1 were confirmed by Giemsa staining, exon sequencing, immunofluorescence and xenograft model in vivo. Bone lesion was evaluated by Tartrate-resistant acid phosphatase staining. The existence of circCHEK1 246aa was evaluated by qPCR, Sanger sequencing and Mass...
