Project description:The transcriptional profile of the human multiple myeloma (MM) cell line MM.1S treated with MLN4924 vs control MM.1S cells was characterized by oligonucleotide microarray analysis, using the human U133 plus 2.0 Affymetrix GeneChip, according to previously described protocols for total RNA extraction and purification; cDNA synthesis; in vitro transcription reaction for production of biotin-labeled cRNA; hybridization of cRNA with U133plus2.0 Affymetrix gene chips; and scanning of image output files. Scanned image output files were analyzed using DNA-Chip Analyzer (dChip) (www.dchip.org), including conversion to DCP files, normalization and modeling. The gene expression profile of MM.1S cells for each time point of MLN4924 treatment was compared to the profile of control MM.1S cells. The NEDD8 activating enzyme (NAE) is upstream of the 20S proteasome in the ubiquitin/proteasome pathway and catalyzes the first step in the neddylation pathway. NEDD8 modification of cullins is required for ubiquitination of cullin-ring ligases (CRLs), which regulate degradation of a distinct subset of proteins. The more targeted impact of NAE on protein degradation prompted us to study MLN4924, an investigational NAE inhibitor, in preclinical multiple myeloma (MM) models. In vitro treatment with MLN4924 led to dose-dependent decrease of viability in a panel of human MM cell lines. In this analysis, we evaluated the molecular changes triggered in MM.1S myeloma cells by their in vitro treatment with MLN4924. The transcriptional profiles of each experimental condition were characterized by oligonucleotide microarray analysis, using the human U133 plus 2.0 Affymetrix GeneChip. The human multiple myeloma (MM) cells MM.1S were cultured in vitro in the presence or absence of the NEDD8 activating enzyme (NAE) inhibitor MLN4924 for 8, 16 or 24hrs. The gene expression profiles of drug treated cells were compared with the profiles of control MM.1S cells.

Project description:MLN4924, also known as pevonedistat, is a small molecule inhibitor of NEDD8 activating enzyme (NAE), that inhibits the entire neddylation pathway. As the first-in-class neddylation inhibitor, MLN4924 is currently in Phase I/II clinical trials for anticancer application as a single agent or in combination with chemotherapeutic drugs. MLN4924 has shown impressive anticancer activity by inactivating Cullin-RING ligases (CRLs) to cause accumulation of tumor suppressor substrates. Whether MLN4924 regulates the RNA expression by modulating the levels of transcription factor/repressor remain elusive. In this study, we treated A549 lung cancer cells with MLN4924 at 0.25 or 0.5 µM for 8 or 24 hrs, respectively, followed by RNAseq analysis. Here we found that MLN4924 significantly decreases the SOX2 mRNA level. The mechanistic study revealed that MLN4924 inhibits FBXW2 E3 to cause MSX2 accumulation, which in turn transcriptionally represses SOX2, leading to suppression of stem cell property and sensitization of cancer cells to tamoxifen.

Project description:Novel targeted agents used in therapy of lymphoid malignancies, such as inhibitors of B-cell receptor-associated kinases, are recognized to have complex immune-mediated effects. NEDD8-activating enzyme (NAE) has been identified as a tractable target in chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma. We and others have shown that pevonedistat (TAK-924), a small molecule inhibitor of NAE, abrogates NF-κB signaling in malignant B cells. However, NF-κB pathway activity is indispensable in immune response, and T-cell function is altered in patients with CLL. Using T cells derived from patients with CLL, we demonstrate that while targeting NAE results in markedly differential expression of NF-κB-regulated genes and downregulation of IL-2 signaling during T-cell activation, T cells evade apoptosis. Meanwhile, NAE inhibition favorably modulates polarization of T cells in vitro, with decreased Treg differentiation and a shift towards TH1 phenotype, accompanied by increased interferon-γ production. These findings were recapitulated in vivo in immunocompetent mouse models. T cells exposed to pevonedistat in washout experiments, informed by its human pharmacokinetic profile, recover NAE activity and maintain their response to T-cell receptor stimulation and cytotoxic potential. Our data shed light on the potential immune implications of targeting neddylation in CLL and lymphoid malignancies.

Project description:Glioblastoma is a highly aggressive and lethal brain tumor, with limited treatment options. Abnormal activation of the neddylation pathway is observed in glioblastoma, and the NEDD8-activating enzyme (NAE) inhibitor, MLN4924 was previously shown to be effective in glioblastoma cell line models. However, its effect has not been tested in patient-derived glioblastoma stem cells. Immunohistochemistry and public data were analyzed to determine whether NEDD8 pathway proteins are important in glioblastoma development and patient survival. The effects of MLN4924 were evaluated in 4 glioblastoma cell lines and 15 patient-derived glioblastoma stem cells using high content analysis. Immunoblot analysis assessed the NEDD8 pathway proteins and biomarkers. Whole transcriptome analysis identified pathways associated with MLN4924 sensitivity. NAE1 and UBA3 levels increased in glioblastoma patients; high NEDD8 levels were associated with poor clinical outcomes. Glioblastoma cell lines and patient-derived stem cells were highly susceptible to MLN4924, while normal human astrocytes were resistant. Genomic analyses indicated that MLN4924 sensitive cells exhibited enrichment of ERK and AKT signaling. We verified that MLN4924 inhibits ERK and AKT phosphorylation in MLN4924 sensitive cells. Our findings suggest that patient-derived glioblastoma stem cells in the context of ERK and AKT activation are sensitive and highly regulated by neddylation inhibition.

Project description:Multiple sclerosis (MS) is an autoimmune disease of the central nervous system in which both genetic and environmental factors are thought to be involved. Genome-wide association studies revealed more than 200 risk loci, most of which harbor genes primarily expressed in immune cells. However, whether genetic differences are translated into cell-specific gene expression profiles and to what extent these are altered in MS are not well understood. To assess cell-type-specific gene expression in a large cohort of MS patients, we sequenced the whole transcriptome of sorted T cells (CD4+ and CD8+) and CD14+ monocytes from treatment-naive MS patients (n=122) and healthy subjects (n=22). Next, we performed a comprehensive analysis of the RNA sequencing dataset and identified 612 differentially expressed genes (DEGs) in CD14+ monocytes, 464 in CD4+ T cells, and 93 in CD8+ T cells. Notably, about one third (36.6%) of DEGs were non-coding RNAs, the majority of which (88.2%) were down-regulated in MS. We identified large co-expressed gene modules and cis-eQTLs with key MS genes in each cell subset. Importantly, we discovered dysregulation of NAE1, a subunit of NEDD8 activating enzyme (NAE), in CD4+ T cells which activates the neddylation pathway. Finally, we demonstrated that NAE inhibition using Pevonedistat (MLN4924) dampened disease severity in murine experimental autoimmune encephalomyelitis (EAE). Our findings provide novel insights into MS-associated gene regulation unraveling neddylation as a crucial pathway in MS pathogenesis with implications for the development of tailored disease-modifying agents.

Project description:Lysine-specific demethylase 1A (LSD1) specifically demethylates di- and monomethylated histone H3K4 or K9, resulting in context-dependent transcriptional repression or activation. We previously identified an irreversible LSD1 inhibitor T-3775440, which exerts antileukemic activities in a subset of acute myeloid leukemia (AML) cell lines by inducing cell transdifferentiation. The NEDD8-activating enzyme inhibitor pevonedistat (MLN4924, TAK-924) is an investigational drug with antiproliferative activities in AML, and is also reported to induce cell differentiation. We therefore tested the combination of these two agents in AML models.The combination treatment resulted in synergistic growth inhibition of AML cells, accompanied by enhanced transdifferentiation and suppression of the leukemic stem cell gene signature.

Project description:Triple negative breast cancer (TNBC) accounts for 15-20% of breast cancer cases in the United States. Systemic neoadjuvant chemotherapy (NACT), with or without immunotherapy, is the current standard of care for patients with early-stage TNBC. However, up to 70% of TNBC patients have significant residual disease once NACT is completed, which is associated with a high risk of developing recurrence within two to three years of surgical resection. To identify targetable vulnerabilities in chemoresistant TNBC, we generated longitudinal patient-derived xenograft (PDX) models from TNBC tumors before and after patients received NACT. We then compiled transcriptomes and drug response profiles for all models. Transcriptomic analysis identified the enrichment of aberrant protein homeostasis pathways in models from post-NACT tumors relative to pre-NACT tumors. This observation correlated with increased sensitivity in vitro to inhibitors targeting the proteasome, heat shock proteins, and neddylation pathways. Pevonedistat, a drug annotated as a NEDD8-activating enzyme (NAE) inhibitor, was prioritized for validation in vivo and demonstrated efficacy as a single agent in multiple PDX models of TNBC. Pharmacotranscriptomic analysis identified a pathway-level correlation between pevonedistat activity and post-translational modification (PTM) machinery, particularly involving neddylation and sumoylation targets. Elevated levels of both NEDD8 and SUMO1 were observed in models exhibiting a favorable response to pevonedistat compared to those with a less favorable response in vivo. Moreover, a correlation emerged between the expression of neddylation-regulated pathways and tumor response to pevonedistat, indicating that targeting these PTM pathways may prove effective in combating chemoresistant TNBC.

Project description:Protein neddylation modification is catalyzed by a neddylation activating enzyme (NAE, E1), an E2 conjugating enzyme and an E3 ligase. In various types of human cancers, the neddylation pathway was abnormally activated. Our previous study validated that neddylation E2 UBE2F is a promising lung cancer target. However, although NAE inhibitor MLN4924/pevonedistat is currently in few clinical trials for anticancer application, no small molecule was reported that targets UBE2F. Here, we report, for the first time, the discovery, via structure-based virtual screen and chemical optimization, of such a small molecule, designated as HA-9104. HA-9104 binds to UBE2F, reduces its protein levels, and consequently inhibits cullin-5 neddylation to inactivate CRL5 (cullin-RING ligase-5) ligase, leading to accumulation of CRL5 substrate, NOXA, to induce apoptosis. Moreover, HA-9104 appears to form the DNA adduct via its 7-azaindole group to induce DNA damage and G2/M arrest. Biologically, HA-9104 effectively suppresses the growth and survival of lung cancer cells and confers radiosensitization in both in vitro cell culture and in vivo xenograft tumor models. Taken together, our study discovered a small molecule HA-9104 that targets the UBE2F-CRL5 axis with anticancer activity alone or in combination with radiation.
