Bortezomib resistance in THP-1 cell line

ABSTRACT: Bortezomib is a proteasome inhibitor used in severel different hematological malignancies. Resistance to this drug is still poorly understood. In order get more insight in the resistance mechanism, we developed several bortezomib resistant subclones of the THP-1 monocytic/macrophage cell line. On these subclones expression arrays were performed. We performed expression array three different bortezomib resistant subclones of the THP-1 cell line. The resistant subclones were spotted against the parental THP-1 wildtype cell line.

The proteasome inhibitor bortezomib is a novel anticancer drug that has shown promise in the treatment of refractory multiple myeloma. However, its clinical efficacy has been hampered by the emergence of drug-resistance phenomena, the molecular basis of which remains elusive. Toward this end, we here developed high levels (45- to 129-fold) of acquired resistance to bortezomib in human myelomonocytic THP1 cells by exposure to stepwise increasing (2.5-200 nM) concentrations of bortezomib.
