Project description:RNA was extracted from myeloma cell lines that were either drug-naïve or resistant to bortezomib or carfilzomib and the transcriptome was characterised using RNA sequencing.
Project description:Expression array data was used to compare parental FGFR3-TACC3 fusion-driven urothelial cell lines with their FGFR inhibitor-resistant derivatives. In this dataset, we include RT112 and RT4 parental cells, RT112 cells acutely treated with PD173074 (24 h), RT112 and RT4 resistant derivatives cultured with drug and their resistant derivatives cultured for four to six passages out of drug.
Project description:Modulation of the activity of the ubiquitin-proteasome pathway with the proteasome inhibitor (PI) is an established component of therapy for plasma cell disorders. However, resistance emerges and the mechanism is incompletely understood. We generated carfilzomib-resistant (CR) myeloma cell lines by exposing drug-naive ANBL-6, KAS-6/1, U266, and OPM-2 cells to increasing concentrations of carfilzomib and then performed gene expression profiling (GEP) to identify prominent changes compared to their vehicle-treated counterparts, followed by exploration of the mechanism(s) of proteasome inhibitor resistance.
Project description:Sequencing of olaparib-resistant PEO1 derivatives (C4, C5, C10 and C18) and parental PEO1 (P1 and P2) cells was performed in order to determine mechanisms of acquired resistance in the resistant cell lines. PEO1 parental cell lines were authenticated prior to sequencing. PEO1 parental were confirmed to be BRCA2-mutated (5139C>G). Olaparib PEO1 resistant cells were generated through a step-wise escalation of olaparib (10nM to 8uM olaparib). In olaparib resistant lines an increase canonical Wnt signaling and loss of of non-canonical Wnt signaling was observed.
Project description:Copy number analysis to compare parental colorectal cancer cell lines and their selumetinib-resistant derivatives and identify gene copy changes that might contribute to resistance
