Next Generation Sequencing Facilitates Quantitative Analysis of transcriptomes in MM.1S cells treated with DMSO, All-trans retinoic acid (ATRA), carfilzomib (Cfz), and their combinations

Project description:ATRA is important for sensitizing MM cells to Cfz. To determine what signalling pathways are affected by ATRA+Cfz in MM cells, MM.1S MM cell line was pulsed with Cfz and then cultured with DMSO or 10µM ATRA for 12 h. Total RNAs of 2 x 106 MM.1S cells for each sample were extracted by RNeasy Mini Kit (Qiagen). 5-10 µg RNA samples were sent to Cancer Genomics Center at The University of Texas (Houston, TX) for genearray followed by data analysis. We use gene experssion profiling data to determine differential expression of genes in MM cells in culture with DMSO, ATRA, Cfz or ATRA+Cfz.

Expression data from DMSO- and ATRA-treated human multiple myeloma (MM) cells

Project description:All-trans retinoic acid (ATRA) is important for sensitizing MM cells to carfilzomib (Cfz). To determine what signalling pathways are affected by ATRA in Cfz-treated MM cells, MM.1S MM cell line was pulsed with Cfz and then cultured with DMSO or 10µM ATRA for 12 h. Total RNAs of 2 x 106 MM.1S cells were extracted by RNeasy Mini Kit (Qiagen). 5-10 µg RNA samples were sent to Gene Expression and Genotyping Facility at Case Western Reserve University (Cleveland, OH) for genearray followed by data analysis. We use microarray data to determine differential expression of genes in Cfz-treated MM cells in culture with DMSO and ATRA.

Comparison of the gene expression profiles of carfilzomib-resistant derivatives versus parental human myeloma cell lines

Project description:KMS-11 and KMS-34 cells were exposed to stepwise increasing concentrations of carfilzomib over a period of 18 weeks: cells adapted to growth in 4 nM carfilzomib by 4 weeks, in 6 nM in another 6 weeks and in 12 nM after a further 8 weeks. The resulting cell cultures, denoted KMS-11/Cfz and KMS-34/Cfz, respectively, retained resistance to carfilzomib even when tested after removal of selective pressure for approximately 8 weeks. KMS-11/Cfz and KMS-34/Cfz cells were profiled for gene expression after 1 week of growth in the absence of carfilzomib together with parental KMS-11 and KMS-34 cells which had not been selected in the drug (triplicate samples).

Comparative expression analysis of carfilzomib-resistant and parental LP-1 human multiple myeloma cells

Project description:LP-1 cells were exposed to stepwise increasing concentrations of carfilzomib over a period of 18 weeks: cells adapted to growth in 4 nM carfilzomib by 4 weeks, in 6 nM in another 6 weeks and in 12 nM after a further 8 weeks. The resulting cell culture, denoted LP-1/Cfz, retained resistance to carfilzomib even when tested after removal of selective pressure for approximately 8 weeks.

Novel carfilzomib-based combinations as potential therapeutic strategies for liposarcomas

Project description:Proteasome inhibitors, such as bortezomib and carfilzomib, have shown efficacy in anti-cancer therapy in hematological diseases but not in solid cancers. Here, we found that liposarcomas (LPS) are susceptible to proteasome inhibition, and identified drugs that synergize with carfilzomib, such as selinexor, an inhibitor of XPO1-mediated nuclear export. Through quantitative nuclear protein profiling and phospho-kinase arrays, we identified potential mode of actions of this combination, including interference with ribosome biogenesis and inhibition of pro-survival kinase PRAS40. Furthermore, by assessing global protein levels changes, FADS2, a key enzyme regulating fatty acids synthesis, was found down-regulated after proteasome inhibition. Interestingly, SC26196, an inhibitor of FADS2, synergized with carfilzomib. Finally, to identify further combinational options, we performed high-throughput drug screening and uncovered novel drug interactions with carfilzomib. For instance, cyclosporin A, a known immunosuppressive agent, enhanced carfilzomib’s efficacy in vitro and in vivo. Altogether, these results demonstrate that carfilzomib and its combinations could be repurposed for LPS clinical management.

Differential protein expression between Carfilzomib-sensitive (AMO1) and resistant (AMO1-CFZ) multiple myeloma cells

Project description:Carfilzomib-sensitive (AMO1) and resistant (AMO1-CFZ) MM cells were grown in RPMI-1640 medium supplemented with 10 % FBS and 0.68 mM L-glutamine, in a humidified incubator at 5% CO2 and 37 °C. The AMO1-CFZ medium was additionally added 90 nM CFZ, while the CFZ sensitive AMO1 cells were added vehicle (0.009 % DMSO) only. AMO1-CFZ was either harvested directly or grown for 1 week in CFZ free medium (vehicle only) prior to harvest. AMO1 and carfilzomib-resistant AMO1-CFZ cells were resuspended in 100 µl 1% sodium deoxycholate, 100 mM Tris-HCl pH 8.5, 10 mM tris(2-carboxyethyl)phosphine (TCEP), 40 mM chloroacetamide (CAA), heated at 90 °C for 45 min and sonicated for 10 cycles (30 s ON/30 s OFF) using a Bioruptor pico sonicator. After centrifugation at 16000 × g for 10 min, 50 µg soluble protein from each sample was added 100 µl 0.1M ammonium bicarbonate, 0.5 µg trypsin and digested overnight at 37°C. Peptides were desalted using C18 spin columns, dried in a speedvac centrifuge and resuspended in 0.1% formic acid prior to MS analysis. Label-free quantitatative (LFQ) LC-MS/MS was performed on a timsTOF Pro (Bruker Daltonics) connected to a nanoElute (Bruker Daltonics) HPLC. Peptides were separated over a Bruker PepSep C18 (75 µm × 15 cm) column with running buffers A (0.1 % formic acid) and B (0.1 % formic acid in acetonitrile) using a 100 min gradient from 2 % B to 40 % B. The timsTof instrument was operated in the DDA PASEF mode with 10 PASEF scans per acquisition cycle and accumulation and ramp times of 100 ms each. The ‘target value’ was set to 20000 and dynamic exclusion was activated and set to 0.4 min. The quadrupole isolation width was set to 2 Th for m/z < 700 and 3 Th for m/z > 800.
