Bortezomib resistance in Mantle Cell Lymphoma (MCL) is associated with plasmacytic differentiation

ABSTRACT: Bortezomib-induced resistant MCL cell lines (HBL2 BR and JEKO BR) were generated by continuous cultured of corresponding parental cell lines (HBL2 PT and JEKO PT) with increasing bortezomib concentrations The IC50 of bortezomib of BR cell lines was 80 fold higher than the IC50 of the parental clone for HBL2-BR and 40 fold higher for JEKO-BR.RNA was isolated from cells collected at different time points within the period of one month in triplicate for HBL2 and in duplicate for JEKO subclones. This material was used for gene expression analysis using Affymetrix platform. Keywords: RNA

Bortezomib resistance in THP-1 cell line

Project description: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.

Bortezomib resistance in CCRF-CEM cell line [miRNA]

Project description: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 CCRF-CEM T-ALL cell line. On these subclones comparative Genome hybridization (arrayCGH) for DNA copy number analysis gene expression and micro-RNA expression arrays were performed. We performed micro-RNA on two different bortezomib resistant subclones of the CCRF-CEM cell line. The resistant subclones were compared to the parental CCRF-CEM wildtype cell line.

A Subset of Genes Can Distinguish between Bortezomib Responsive Versus Bortezomib Resistant Myeloma

Project description:Gene expression profile (GEP) was analyzed from cultured bone marrow (BM) samples from patients with bortezomib responsive versus bortezomib resistant myeloma after 6-8 hours incubation in vitro with bortezomib 2 µg/ml or with PBS. Case D also had a fresh BM sample taken 75 minutes after IV injection of bortezomib.
