The LSD1/KDM1A neuro-specific isoform regulates neuronal differentiation through H3K9 demethylation [Affymetrix]

Project description:During brain development, histone-modifying enzymes play an important role by orchestrating transcriptional programs that regulate neuronal maturation. Lysine-Specific Demethylase 1 (LSD1, also named as KDM1A) functions as a transcriptional repressor by removing methyl groups at lysine 4 of histone H3 (H3K4). In neurons, alternative splicing can include an additional exon (exon E8a) within LSD1 transcripts, generating a LSD1+8a neuro-specific isoform. We here report that LSD1+8a isoform does not have the intrinsic ability to demethylate H3K4. LSD1+8a functions as a co-activator on its target genes by removing H3K9 repressive histone marks. We identify the supervillin protein (SVIL) as a LSD1+8a interacting partner and demonstrate that SVIL protein regulates neuronal maturation by controlling LSD1+8a mediated H3K9 demethylation. Thus, our results show that alternative splicing provides a genius mechanism by which LSD1 isoforms can acquire a dual specificity (H3K9 vs H3K4) and therefore differentially control specific gene expression patterns during brain development. In order to find some LSD1+8a regulated genes at differentiated SH-SY5Y cell lines, we infected SH-SY5Y with control or LSD1+8a shRNA, then induced differentiation with RA and BDNF, (Retinoic acid (RA) (Sigma) was added at a final concentration of 10 μM the next day after plating. After 4 days, the cells were washed three times with PBS and incubated with 50 ng/mL of Brain Derived Neural Factor (BDNF) (Millipore) in serum-free medium for 3 days), we extracted RNA from BDNF induced SH-SY5Y cells for expression analysis.Duplicates were included for Affymetrix Human transcriptome version 2 array.

Effects of the histone demethylase LSD1/KDM1A on the gene expression program of murine hematopoietic progenitor cells.

Project description:We established transgenic mice overexpressing the histone demethyase LSD1/KDM1A under the control of Sca-1 promoter and investigated the global changes in gene expression in hematopoietic progenitor cells using a microarray- based approach. We isolated mRNA from Sca-1-positive hematopoietic progenitor cells from two transgenic mice, Line 6 and Line 3, and subjected them to gene expression analysis using an Affimetrix GeneChip Array.

Maternal LSD1/KDM1A is an essential regulator of chromatin and transcription landscapes during zygotic genome activation

Project description:How the parental genomes of the very specialized sperm and oocyte cells are remodelled upon fertilization to confer totipotency has remained a tantalizing open questions. Indeed, in the case of mammals, the parental genomes undergo dramatic reprogramming upon fertilization, including differential dynamics of histone post-translational modifications. The roles of histone modifying enzymes in this process, which are maternally provided, are only just starting to emerge. Here, we explore the function of the oocyte inherited pool of Lsd1/Kdm1a, which encodes a histone H3K4 and K9 demethylase, during early mouse development. Maternal deficiency of Lsd1/Kdm1a results in developmental arrest by the two-cell stage, associated with dramatic and stepwise alterations in H3K9 and H3K4 methylation patterns depending on its demethylase activity. At the transcriptional level, two major changes occur. On one hand, switch from maternal-to-zygotic program fails to be induced. On the other hand, LINE-1 retrotransposons are not properly silenced, along with evidences for increased LINE-1 activity. We propose that Lsd1/Kdm1a is involved in the correct establishment of epigenetic information harboured by histones and is involved in the initiation of new pattern of genome expression driving early mouse development and preserving genome integrity

Cyclic LSD1 recruitment and dynamic H3K4 methylation establish TRIM24-activated estrogen response

Project description:The role of histone lysine methylation in estrogen receptor-alpha (ERα)-activated transcription is highly context-specific and poorly understood. Here, we show that lysine demethylase 1 (LSD1) mediates loss of H3 lysine 4 dimethylation (H3K4me2) in coordination with tripartite-motif-containing protein 24 (TRIM24)- regulated growth of breaset cancer-derived cells. We performed global profiling of histone H3K4me2 in comparison to genome-wide binding of TRIM24 in MCF7 cells when estrogen is depleted or added. We found specific subsets of genes with functions in transcription and cell proliferation are depleted of H3K4me2 at TRIM24 binding sites. Chromatin immunoprecipitation (ChIP) analyses over a time course of estrogen induction revealed cyclic demethylation of H3K4me2, LSD1, TRIM24 and ERα binding. Inhibition of LSD1 enzymatic activity led to increased H3K4me2 and decreased estrogen response of TRIM24-dependent genes. Additon of a small molecule inhibitor of the TRIM24 bromodomain or depletion of TRIM24 expression amplified the impact of LSD1 inhbition as measured by survival and proliferation of MCF7 cells, suggesting that combinatorial inhibition of LSD1 and TRIM24 may be effective in targeting ER-positive breast cancers.
