Synergistic Interaction Between the LSD1 Inhibitor T-3775440 and the NEDD8-activating Enzyme Inhibitor Pevonedistat (TAK-924/MLN4924) Promotes Anti-Acute Myeloid Leukemia Effects

ABSTRACT: 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.

Expression data from ependymal cell cultures treated with MLN4924.

Project description:We identified that Foxj1 is degraded by the ubiquitin proteasome system. Foxj1 protein is stabilized by the cullin-RING ligase inhibitor MLN4924. We evaluated global changes to ependymal cell culture gene expression profiles during MLN4924 treatment.

A novel LSD1 inhibitor T-3775440 induces transdifferentiation in AML cell lines

Project description:We describe the anti-leukemic activity and mechanism of action of T-3775440, a novel irreversible LSD1 inhibitor. Cell growth analysis of leukemia cell lines revealed that acute erythroleukemia (AEL) and acute megakaryoblastic leukemia cells (AMKL) are highly sensitive to this compound. T-3775440 treatment enforced transdifferentiation-like phenotypic change from erythroid/megakaryocytic lineages into granulomonocytic lineage. Our findings provide the rationale for testing LSD1 inhibitors as potential treatments with a novel mechanism of action for AML, particularly AEL and AMKL.

Regulation of stem cell property and drug resistance of cancer cells by targeting transcriptional machinery via inhibition of neddylation

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.

HiRIEF-LC-MS based proteomics on Small Intestinal Neuroendocrine Tumors (SI-NET) and SI-NET cell lines

Project description:Associated to PXD009877 which contains Part I and Part II. Part III – Pevonedistat/MLN4924 and Bortezomib treatment of the SI-NET (small intestinal – neuroendocrine tumor) cell line CNDT2. High Resolution Isoelectric Focusing (HiRIEF) LC-MS and relative quantification by TMT 10-plex was used to analyze cellular response to the proteasome inhibitor Bortezomib alone or in combination with the neddylation inhibitor pevonedistat (MLN4924) at 12h after treatment in the CNDT2 cell line. The data was obtained from one TMT 10-plex experiment which included 4 untreated controls (TMT channels 126, 127N, 127C and 128N), 3 samples treated with 500 nM Bortezomib for 12 hours (TMT channels 128C, 129N and 129C) as well as 3 samples treated with both Bortezomib and Pevonedistat at 500 nM respectively for 12 hours (TMT channels 130N, 130C and 131).

Inhibiting neddylation with MLN4924 potentiates hypoxia-induced apoptosis of mouse type B spermatogonia GC-2 cells

Project description:Hypoxia, an inadequate supply of tissue oxygen tension, has been reported to induce apoptosis of spermatogenic cells and is associated with male infertility. Neddylation, a post-translational modification similar to ubiquitination, has been shown to be involved in the hypoxia stress response. However, the functions of neddylation in hypoxia-induced apoptosis of spermatogenic cells and its association with male infertility remain largely unexplored. In this study, aiming to explore the role of neddylation in male infertility, we used the specific neddylation inhibitor MLN4924 for treatment in mouse type B spermatogonia GC-2 cells. Our results showed that MLN4924 had no apparent effect on GC-2 cell apoptosis under normoxia, but significantly increased apoptotic cells under hypoxia. Transcriptomic analysis and qPCR assay confirmed that MLN4924 could suppress the expression of hypoxia target genes in GC-2 cells under hypoxia. In addition, MLN4924 could enhance the induction of intracellular and mitochondrial reactive oxygen species (ROS) under hypoxia. These results indicate that the neddylation inhibitor MLN4924 potentiates hypoxia-induced apoptosis of mouse type B spermatogonia GC-2 cells, and neddylation may play an important role in promoting spermatogenic cells to adapt to hypoxia stress.

A Protein Neddylation Inhibitor MLN4924 Suppresses Patient-Derived Glioblastoma Cells via Inhibition of ERK and AKT Signaling

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.
