• Description: Multiple myeloma (MM) is a malignancy of differentiated B-lymphocytes characterized by accumulation of clonal plasma cells (PCs) in the bone marrow. Genome of malignant PCs is extremely unstable and characterized by complex combination of structural and numerical abnormalities. The basis of genomic instability underlying MM is still unclear. Centrosome amplification (CA) is present in about a third of MM cases and may represent a mechanism leading to genomic instability in myeloma. We have previously shown that CA is present in pre-plasma cells stages of B-cell development. Aims: The objective of our study was to evaluate changes in expression of chosen key genes involved in centrosome duplication process in both B and PCs, including their possible changes during MM progression.
