(Submitter supplied) To analyze the functional relevance of LSD1 in neuroblastic tumors, SH-SY5Y cells were transiently transfected with siRNA directed against LSD1 or with a scrambled control siRNA. Microarray analysis revealed changes in expression that were consistent with these observations 72 hours after LSD1 knock-down. At this time, 28 genes were significantly induced at least 1.5-fold and 29 genes were significantly repressed at least 1.5-fold. more...

(Submitter supplied) Lysine-specific demethylase 1 (LSD1) is involved in gene regulation and development; however, its precise function, molecular targets and underlying mechanisms during development are poorly understood. Here, we show that LSD1 is required for neuronal progenitor cell (NPC) maintenance during cortical development. A ChIP-seq analysis identified a LSD1 binding site (LBAL) downstream of Atrophin1 (ATN1). more...

(Submitter supplied) Histone H3 lysine 27 to methionine mutations (H3K27M) resulting in aberrant chromatin regulation are frequently observed in Diffuse Intrinsic Pontine Glioma (DIPG), a pediatric brain tumor with no cure. We conducted a CRISPR screen to determine if various chromatin regulators might be targeted to treat DIPG. Excitingly, this genetic screen reveals that co-targeting lysine specific demethylase 1 (LSD1) and histone deacetylases (HDACs) results in an enhanced growth suppressive effect in patient DIPG cells. more...

(Submitter supplied) Epigenetic alterations appear to modulate Myc signaling. We investigated the role of the histone demethylase JMJD2B in Myc-mediated neuroblastoma pathogenesis. We demonstrate that Myc physically interacts with and recruits this epigenetic modifier, which removes repressive H3K9 methyl marks from Myc-target genes. JMJD2B regulates neuroblastoma proliferation and, together with MYCN amplification, identifies a subgroup of poor prognosis patients. more...

(Submitter supplied) Lysine specific demethylase 1 (LSD1), which demethylates mono- and di- methylated histone H3-Lys4 as part of a complex including CoREST and histone deacetylases (HDAC), is essential for embryonic development in the mouse beyond e6.5 days. Here, we demonstrate that LSD1 expression and therefore function, is restricted to the epiblast of the post- implantation embryo. Conditional deletion of LSD1 in mouse embryonic stem (ES) cells, in vitro counterpart of the epiblast, revealed a reduction in CoREST protein, a subsequent decrease in associated HDAC activity and a global increase in Histone H3 Lys56 acetylation. more...

(Submitter supplied) Regulation of spatiotemporal gene expression in higher eukaryotic cells is critical for the precise and orderly development of undifferentiated progenitors into committed cell types of the adult. Recently, dynamic epigenomic regulation, including chromatin remodeling and histone modifications by transcriptional coregulator complexes, has been shown to be involved in transcriptional regulation. Precisely how these coregulator complexes exert their cell-type and developing stage-specific activity is largely unknown. more...

(Submitter supplied) Next Generation Sequencing with differdent pluripotent transcript factor overexpression in MEF Somatic cells can be reprogrammed into induced pluripotent stem cells (iPSCs) by defined factors. The low efficiency of reprogramming limited the potential application of iPSCs. Here we found that knockdown LSD1 , which demethylates histone H3 Lys 4 or 9 , could increase iPSCs generation. It has been reported that LSD1 interaction with Oct4 which is the core factor of reprogramming. more...

(Submitter supplied) We report the identification of LSD1 binding genomic regions in mouse embryonic stem cells (ESC) by high throughput sequencing. By obtaining over 10 million 36 bp reads of sequence from each chromatin immunoprecipitated DNA, we generated genome-wide maps for LSD1 and histone H3 dimethylated on lysine 4 (H3K4me2), the substrate for LSD1 in mouse ESCs. Our results showed an extensive overlap between the LSD1 and H3K4me2 genomic regions and a correlation between the genomic levels of LSD1/H3K4me2 and gene expression, including many highly expressed ESC genes. more...

(Submitter supplied) Transcription factors and chromatin modifiers play important roles in programming and reprogramming of cellular states during development. Much is known about the role of these regulators in gene activation, but relatively little is known about the critical process of enhancer silencing during differentiation. Here we show that the H3K4/K9 histone demethylase LSD1 plays an essential role in decommissioning enhancers during differentiation of embryonic stem cells (ESCs). more...
