Genome-wide occupancy of LSD1 in HEL human erythroleukemia cell line.

ABSTRACT: We examined the genome-wide distribution of LSD1 bound regions in HEL cells bya ChIP-seq analysis. We found that GATA family transcription factors co-operate with LSD1 to regulate metabolic genes. We also found that LSD1 binds to and represses CEBPA gene enhancer, resulting in the suppression of myeloid cell properties.

Effect of LSD1 knockdown on histone H3K4 methylation in HEL human erythroleukemia cell line.

Project description:To understand the role of LSD1 in regulating histone H3K4 methylation status, ChIP-seq analyse of mono- and di-methylated H3K4 in LSD1-KD HEL cells were performed. The analyses revealed demethylation of H3K4me1 and H3K4me2 by LSD1 at regulatory regions including CEBPA gene enhancer.

PolyA RNA sequencing of HEL human erythroleukemia cell line under LSD1 inhibition

Project description:To understand the role of LSD1 in transcriptional regulation, RNA-seq analyses of LSD1-inhibited HEL cells were carried out. Cells were collected after the introduction of lentiviral LSD1 shRNA or the treatment with a specific LSD1 inhibitor, S2101. We found that LSD1 inhibition led to decreased expression of genes involved in various metabolic pathways.

Differential gene expression profiling by LSD1 inhibition using novel LSD1 inhibitors (NCD25 and NCD38)

Project description:LSD1 is a demethylase of histone modification H3k4me1 and H3K4me2. We have developed novel LSD1 inhibitors (NCD25 and NCD38) and found that they are effective to myelodysplastic syndromes and leukemia cells. To understand what mechanisms are affected by these compounds, we employed gene expression profiling analyses. Gene expression profiling data were obtained from HEL, MDS-L, or CMK11-5 cells treated with DMSO (control), NCD25, or NCD38 and compared each other. Expression of eleven transcriptional factors (GFI1, CEBPA, SPI1, MNDA, TAL1, GATA1, NFE2, RXRA, HOXA9, GATA2, and PBX1) was reconfirmed by q-PCR with the same samples. Gene expression of leukemia cells was measured after 48 hours incubation with or without LSD1 inhibitors. Five independent experiments were performed using 3 cell lines (HEL, MDS-L and CMK11-5) and 2 drugs (NCD38 and NCD25).

Differential gene expression profiling by deletion of GFI1 super-enhancer (GFI1-SE-KO) upon treatment of a LSD1 inhibitor NCD38 in HEL cells

Project description:Activation of GFI1-super-enhancer (GFI1-SE) by a LSD1 inhibitor NCD38 was relevant to myeloid differentiation and antileukemia effect in human erythroleukemia cells (HEL cells). Thus, we investigated the role of GFI1-SE upon NCD38 treatment in HEL cells. We established three independent sublines with bi-allelic deletion of GFI1-SE (CCE2 #114, #141, and #216) using CRISPR-Cas9 genome editing system in HEL cells and a classical limiting dilution method. Control sublines (Ctrl C1, C2, and C5) were established by transfection of parent vector and limiting dilution. After treatment of each subline with DMSO or NCD38 (LSD1i) for 24 hours, these gene expression profiling data were obtained.

gene expression data from cep701 treated HEL cells and shPRMT5 knocking down HEL cells

Project description:compare the gene expression profile between cep701 treated HEL cells with shPRMT5 knockingdown HEL cells. HEL cells contain homologous alells with mutation Jak2V617F. We found JAK2V617F can inactivate PRMT5 activity by directly phosphorylating PRMT5 through histone methylation.

Effect of depletion of KDM4C on gene expression of JAK2-mutated HEL erythroleukemia cells [RNA-seq]

Project description:To investigate the function of KDM4C in progression of leukemia, we established HEL-Cas9 cell lines in which the target gene has been knocked out by CRISPR/Cas9. We then performed transcriptome analysis using data obtained from RNA-seq of control or KDM4C depletd cells.
