Project description:RNA sequencing data for a Ewing sarcoma cell line, A673 treated with DMSO or the LSD1 inhibitor, SP-2509. Monoclonal cell lines were generated by CRISPR/Cas9 mediated KO of mitochondrial genes MRPL45, UQCRFS1, and CYC1. These cells were treated with DMSO or SP-2509 to determine mitochondrial gene KO derived drug resistance.
Project description:The transcriptional profile of LSD1 knockdown in A673 Ewing sarcoma cells mirrors that of EWS/FLI knockdown and LSD1 small molecule inhibition (SP-2509)
Project description:Lysine-Specific Demethylase 1 (LSD1) over-expression correlates with poorly differentiated neuroblastoma and predicts poor outcome despite multimodal therapy. We have studied the efficacy of reversible and specific LSD1 inhibition with HCI-2509 in neuroblastoma cell lines and particularly the effect of HCI-2509 on the transcriptomic profile in MYCN amplified NGP cells. Cell survival assays show that HCI-2509 is cytotoxic to poorly differentiated neuroblastoma cell lines in low micromole or lower doses. Transcriptional profiling of NGP cells treated with HCI-2509 shows a significant effect on p53, cell cycle, MYCN and hypoxia pathway gene sets. HCI-2509 results in increased histone methyl marks and p53 levels along with cell cycle arrest in the G2/M phase and inhibition of colony formation of NGP cells. Our findings indicate that LSD1 inhibition with HCI-2509 has a multi-target effect in MYCN amplified high-risk neuroblastoma cells.
Project description:The epigenetic regulator LSD1 is overepxpressed in lung adenocarcinoma (LUAD). HCI-2509 a LSD1 inhibitor leads to growth arrest in in vitro tumor models. To identify the underlying molecular mechanims behind LSD1 overexpression, we examined the gene expression patterns using microarray in the LUAD cell line PC9 after HCI-2509 treatment
Project description:Inhibition of LSD1 is a novel option for treatment of lung cancer. Using HCI-2509, a specific inhibitor of LSD1, results in a cell cycle arrest as wel as a shift in global histone 3 lysine 4 and lysine 9 dimethylation pattern. Using microarrays we aim to illucidate the changed transcriptome upon treatement of HCI-2509 in lung adenocarcinoma cell line A549.
Project description:EWS-FLI-1 was silenced by an shRNA in A673 Ewing sarcoma cells and the resulting alterations in the secretome was analyzed by GeLC-MS/MS approach (six gel slices for each sample, luciferase shRNA-expressing cell secretome as control)
Project description:A673 Ewing's sarcoma cells, with inducible EWS/FLI cDNA, harboring the EF-2-RNAi retrovirus, induced (or uninduced) for the indicated time period. Keywords: time course
