Project description:The goal of this experiment is to identify differentially expressed genes between parental OVSAHO cells and CB-5083-resistant OVSAHO cells. Each group is treated with 5 microM CB-5083 for 6 hours and total RNA was extracted with Trizol. RNA sequencing library was performed using Illumina RNA library kit.

Project description:The goal was to determine the gene expression differences between CB-5083 and Bortezomib treated multiple myeloma cell lines Inhibition of the AAA ATPase, p97, was recently shown to be a novel method for targeting the ubiquitin proteasome system (UPS) and CB-5083, a first in class inhibitor of p97, has demonstrated broad antitumor activity in a range of both hematological and solid tumor models. Here, we show that CB-5083 has robust activity against multiple myeloma (MM) cell lines and a number of in vivo MM models. Treatment with CB-5083 is associated with accumulation of ubiquitinated proteins, induction of the unfolded protein response (UPR) and apoptosis. CB-5083 decreases viability in MM cell lines and patient derived MM cells, including those with background proteasome inhibitor (PI) resistance. CB-5083 has a unique mechanism of action that combines well with PIs which is likely owing to the p97-dependent retro-translocation of the transcription factor, Nrf1, which transcribes proteasome subunit genes following exposure to a PI. In vivo studies using clinically relevant MM models demonstrate that single-agent CB-5083 inhibits tumor growth and combines well with MM standard of care agents. Our preclinical data demonstrate the efficacy of CB-5083 in several MM disease models and provide the rationale for clinical evaluation as monotherapy and in combination in MM.

Project description:The goal of this study was to analyze differential gene expression 8 hr after treatment of CB-5083, a small molecule inhibitor of p97 (VCP), in HCT116 cells grown in culture. DMSO treated cells were compared to cells treated with 1uM CB-5083 after 8 hr.

Project description:ATP-competitive p97 inhibitor CB-5339, the successor of CB-5083, is being evaluated in Phase 1 clinical trials for anti-cancer therapy. Different modes of action p97 inhibitors such as allosteric inhibitors are useful to overcome one the major problems of targeted therapy: drug-induced resistance. We previously demonstrated allosteric p97 inhibitor NMS-873 can overcome CB-5083-induced resistance. Here, we found that NMS-873 but not CB-5083 affected glycometabolism. By establishing NMS-873-resistant cell lines and performing both cell-based and proteomic analysis, we confirmed that NMS-873 dysregulates glycometabolism in a p97-independent manner. We then used proteome integral solubility alteration with a temperature-based method (PISA T) to identify NDUFAF5 as one of the potential targets of NMS-873 in the mitochondrial complex I. Overall, we employed chemical proteomics and drug-induced thermal proteome changes to identify drug targets, in combination with drug-resistant cell lines to dissect on- and off-target effects. We also demonstrated that glycolysis inhibitor 2-DG enhanced the anti-proliferative effect of NMS-873. The polypharmacology of NMS-873 can be advantageous for anti-cancer therapy.

Project description:Multiple Myeloma is the second most hematological cancer. RUVBL1 and RUVBL2 forms a subcomplex of many chromatin remodeling complexes implicated in cancer progress. As an inhibitor specific to the RUVBL1/2 complex, CB-6644 exhibits remarkable anti-tumor activity in xenograft models of Burkitt’s lymphoma and multiple myeloma (MM). In this work, we defined transcriptional signatures corresponding to CB-6644 treatment in MM cells and determined underlying epigenetic changes in terms of chromatin accessibility.CB-6644 upregulated biological processes related to interferon response and downregulated those linked to cell proliferation in MM cells. Transcriptional regulator inference identified ATF4/CEBP and E2Fs as regulators for downregulated genes and MED1 and MYC as regulators for upregulated genes. CB-6644-induced changes in chromatin accessibility occurred mostly in non-promoter regions. Footprinting analysis identified transcription factors implied in modulating chromatin accessibility in response to CB-6644 treatment, including ATF4/CEBP and IRF4. Lastly, integrative analysis of transcription responses to various chemical compounds of the molecular signature genes from public gene expression data identified CB-5083, a p97 inhibitor, as a synergistic candidate with CB66-44 in MM cells, but experimental validation refuted this hypothesis.
