Project description:High-risk neuroblastoma is often distinguished by amplification of MYCN and loss of differentiation potential with tumors refractory to retinoic acid differentiation based therapies. Here, we leverage high-throughput drug screening of epigenetic targeted therapies across a large and diverse tumor cell line panel to uncover the hypersensitivity of neuroblastoma cells to GSK-J4, a small molecule dual inhibitor of H3K27 demethylases UTX and JMJD3. Mechanistically, GSK-J4 induced neuroblastoma differentiation and ER stress with accompanying upregulation of PUMA and apoptosis induction. Retinoic acid (RA)-resistant neuroblastoma cells were sensitive to GSK-J4. Additionally, GSK-J4 was effective at blocking the growth of chemorefractory and patient-derived xenograft models of high-risk neuroblastoma in vivo. Further, GSK-J4 and RA combined to induce differentiation, ER-stress and limit the growth of neuroblastomas resistant to either drug alone. In MYCN-amplified neuroblastoma, which is the most prevalent driver gene alteration in the refractory population, PUMA induction by GSK-J4 sensitized tumors to the BCL-2 inhibitor venetoclax, demonstrating that epigenetic targeted therapies and BH3 mimetics can be rationally combined to treat high-risk subset of neuroblastoma. Therefore, H3K27 demethylation inhibition is a promising therapeutic target to treat high-risk neuroblastoma, and H3K27 demethylation can be part of rational combination therapies to induce robust anti-neuroblastoma activity.

Project description:Human leukemia cell line RS4.11 was treated with GSK-3 inhibitor SB216763 for 20 hours. Gene expression profiling was performed to analyze genes affected by GSK-3 inhibition. Human leukemia cell line RS4.11 was grown in vitro and treated with 10 uM GSK-3 inhibitor SB216763 or solvent DMSO for 20 hours. Total RNA was extracted and microarray analysis was performed. Two controls and three inhibitor treatment samples were analyzed.

Project description:Neuroblastoma (NB) is a common pediatric malignancy tumor with poor outcome. Recent studies show that GSK-J4, an inhibitor of lysine 27 of histone 3 (H3K27) demethylases, and KTP-330, a clinically available inhibitor of XPO1 protein, are promising anti-cancer agents. However, their molecular mechanisms in neuroblastoma are still unclear. In this study, we used microarrays to analyze the global change in gene expression as a result of GSK-J4 or KTP-330 treatment in the human neuroblastoma cell line SH-SY5Y.

Project description:The aim of this study is to compare human transcriptomes based on NGS (RNA-seq). The transcriptome of neuroblastoma IMR32 was compared with the transcriptome of neuroblastoma IMR32, which was differentiated for 16 days in the presence of 2.5 mkM BrdU. Methods. Human mRNA profiles of 16-day differentiation of IMR32 neuroblastoma and non-differentiated IMR32 neuroblastoma were obtained by deep three-fold sequencing using Illumina NovaSeq. The mapping is read into the human genome (hg38) using the hisat program. On average, about 89-90% of all data received was unambiguously aligned in each library. The htseq-count utility has counted the number of reads that have been matched against known genes (ncbi - entrezID). The obtained values (cpm - countpermillion) for each gene for each library were combined into one matrix for further analysis. Results: Using an optimized data analysis workflow, we matched about 30 million sequence reads per sample to the human genome (hg38). Filtration, normalization by the method (TMM), variance estimation and differentially expressed genes estimation were performed in the edgeR module. Genes in which the cpm did not exceed 1 in any three libraries were considered low expressing.

Project description:Neuroblastoma is an embryonal tumor which originates from neural crest progenitor cells that fail to differentiate along their predefined route to sympathetic neurons or sympatho-adrenergic adrenal cells. It is the most common extracranial tumor of childhood and accounts for 15% of all childhood cancer deaths. Especially patients suffering from high grade or relapsed neuroblastoma have poor outcome in spite of aggressive treatment regimens including autologous stem cell transplantation. Those patients are in urgent need of additional effective therapies which demands the development of targeted approaches. Dihydroorotatedehydrogenase (DHODH) is the fourth enzyme of the pyrimidine synthesis pathway which oxidizes dihydroorotate to orotate. In recent past it became a potential drug target for cancer treatment because of its keyrole in processing essential pyrimidine nucleotides. On the basis of the existing data, functional inhibition of DHODH is considered to be promising therapeutic option for several tumor entities like advanced colorectal, breast or lung-cancers. Leflunomide is an established drug in treatment of the autoimmune diseases rheumatoid arthritis and multiple sclerosis. In the liver Leflunomide becomes converted to its active metabolite called Teriflunomide, which inhibits the activity of DHODH directly. In recent times Leflunomide is also used for therapy against the Cytomegalovirus and the BK virus. Also for Melanoma was shown recently a decreased growth rate due to Leflunomide treatment in a zebrafish and a mouse model. As Melanoma is a malignant tumor of the skin, which derives also from neural crest progenitor cells, a coherent investigation of effictivity of Leflunomide in neuroblastoma celllines showed first promising results. The aim of our study was to reanalyse the effectivity of Leflunomide in Neuroblastoma and to shed further light in its biological mode of action. Three+B52 biological samples of the human neuroblastoma cell line IMR32 were treated with DMSO or Teriflunomide [118 ￂﾵM]
