Abstract
Histone methylation is dynamically regulated to shape the epigenome and adjust central nuclear processes including transcription, cell cycle control and DNA repair. Lysine-specific histone demethylase 2 (LSD2) has been implicated in multiple types of human cancers. However, its functions remain poorly understood. This study investigated the histone demethylase LSD2 homolog AMX-1 in C. elegans and uncovered a potential link between H3K4me2 modulation and DNA interstrand crosslink (ICL) repair. AMX-1 is a histone demethylase and mainly localizes to embryonic cells, the mitotic gut and sheath cells. Lack of AMX-1 expression resulted in embryonic lethality, a decreased brood size and disorganized premeiotic tip germline nuclei. Expression of AMX-1 and of the histone H3K4 demethylase SPR-5 is reciprocally up-regulated upon lack of each other and the mutants show increased H3K4me2 levels in the germline, indicating that AMX-1 and SPR-5 regulate H3K4me2 demethylation. Loss of AMX-1 function activates the CHK-1 kinase acting downstream of ATR and leads to the accumulation of RAD-51 foci and increased DNA damage-dependent apoptosis in the germline. AMX-1 is required for the proper expression of mismatch repair component MutL/MLH-1 and sensitivity against ICLs. Interestingly, formation of ICLs lead to ubiquitination-dependent subcellular relocalization of AMX-1. Taken together, our data suggest that AMX-1 functions in ICL repair in the germline.

Abstract
The jumonji C (JMJ-C) domain-containing protein is a histone demethylase and is involved in plant stress. However, the function of the JMJ-C gene family in cotton is still not confirmed. Herein, 25, 26, 52, and 53 members belonging to the JMJ-C gene family were identified in Gossypium raimondii, Gossypium arboreum, Gossypium hirsutum, and Gossypium barbadense, respectively. Based on phylogenetic relationships and conserved domains, the JMJ-C genes were categorized into five subfamilies, KDM3, KDM4, KDM5, JMJC, and JMJD6. The chromosomal location, gene structure, motif compositions, and cis-elements have been displayed. The collinear investigation showed that whole-genome duplication event is the mainly power to drive JMJ-C gene family expansion. Transcriptome and qRT-PCR analysis revealed that eight GhJMJs were induced by salt and PEG treatment. Further assays confirmed that GhJMJ34/40 greatly improved salt and osmotic tolerance in Saccharomyces cerevisiae. These results help clarify JMJ-C protein functions in preparation for further study.

Abstract
The epithelial-to-mesenchymal transition (EMT) is a complex transcriptional program induced by transforming growth factor β1 (TGF-β1). Histone lysine-specific demethylase 1 (LSD1) has been recognized as a key mediator of EMT in cancer cells, but the precise mechanism that underlies the activation and repression of EMT genes still remains elusive. Here, we characterized the early events induced by TGF-β1 during EMT initiation and establishment. TGF-β1 triggered, 30–90 min post-treatment, a nuclear oxidative wave throughout the genome, documented by confocal microscopy and mass spectrometry, mediated by LSD1. LSD1 was recruited with phosphorylated SMAD2/3 to the promoters of prototypic genes activated and repressed by TGF-β1. After 90 min, phospho-SMAD2/3 downregulation reduced the complex and LSD1 was then recruited with the newly synthesized SNAI1 and repressors, NCoR1 and HDAC3, to the promoters of TGF-β1-repressed genes such as the Wnt soluble inhibitor factor 1 gene (WIF1), a change that induced a late oxidative burst. However, TGF-β1 early (90 min) repression of transcription also required synchronous signaling by reactive oxygen species and the stress-activated kinase c-Jun N-terminal kinase. These data elucidate the early events elicited by TGF-β1 and the priming role of DNA oxidation that marks TGF-β1-induced and -repressed genes involved in the EMT.

Abstract
Histone demethylation is crucial for proper chromatin structure and to ensure normal development, and requires the large family of Jumonji C (JmjC)-containing demethylases; however, the molecular mechanisms that regulate the substrate specificity of these JmjC-containing demethylases remain largely unknown. Here, we show that the substrate specificity of the Arabidopsis histone demethylase JMJ16 is broadened from Lys 4 of histone H3 (H3K4) alone in somatic cells to both H3K4 and H3K9 when it binds to the meiocyte-specific histone reader MMD1. Consistent with this, the JMJ16 catalytic domain exhibits both H3K4 and H3K9 demethylation activities. Moreover, the JMJ16 C-terminal FYR domain interacts with the JMJ16 catalytic domain and probably restricts its substrate specificity. By contrast, MMD1 can compete with the N-terminal catalytic domain of JMJ16 for binding to the FYR-C domain, thereby expanding the substrate specificity of JMJ16 by preventing the FYR domain from binding to the catalytic domain. We propose that MMD1 and JMJ16 together in male meiocytes promote gene expression in an H3K9me3-dependent manner and thereby contribute to meiotic chromosome condensation.

Abstract
A well-studied subject of epigenetics, the histone methylation located at lysine and arginine is overseen via methyltransferases and demethylases. Lysine-specific demethylase 4A (KDM4A) comprises a lysine demethylase and possesses specificity for H3K9me3 and H3K36me3, which is capable of being used in order to activate histone transcription. Our team examined the expression of KDM4A within Sprague Dawley (SD) rats and further investigated the mechanism via which this phenomena regulates osteogenic variation within the present study. The overexpression of KDM4A facilitated the process of osteoblast differentiation in bone mesenchymal stem cells (BMSC), while the knocking down differentiation via osteoblast was restrained via the suppression of the expression of Runx2, Osterix, alkaline phosphatase (ALP), and osteocalcin (OCN). Knocking down KDM4A lowered levels of the promoter expression of Runx2, osterix, and OCN, and raised levels of H3K27me3 expression. The results demonstrated that KDM4A possesses a crucial role within the differentiation of osteoblasts and furthermore regulates the expression of Runx2, Osterix, and OCN via H3K9me3. The present research may provide new insights into the treatment of bone healing.

Abstract
OBJECTIVE The gut microbiota regulates thermogenesis to benefit metabolic homeostasis at least partially via its metabolite butyrate, and the underlying mechanisms of this regulation are still unclear. In this study, we aim to investigate the role of lysine specific demethylase (LSD1), a histone demethylase and important regulator of thermogenesis, in mediating gut microbial metabolite butyrate regulation of thermogenesis. METHODS The antibiotic cocktail (ABX) was administrated to deplete gut microbiota. Adipose-specific LSD1 knockout mice (LSD1 aKO) were generated by crossing LSD1-lox/lox with adiponectin-cre mice and sodium butyrate and dietary fiber inulin was administrated through oral-gavage. Primary stromal vascular cells were isolated from adipose tissues and differentiated to adipocytes for studying butyrate effects on adipocyte thermogenesis. RESULTS The antibiotic cocktail (ABX)-mediated depletion of the gut microbiota in mice downregulated the expression of LSD1 in both brown adipose tissue (BAT) and subcutaneous white adipose tissue (scWAT) in addition to uncoupling protein 1 (UCP1) and body temperature. Gavage of the microbial metabolite butyrate in ABX-treated mice reversed the thermogenic functional impairment and LSD1 expression. The adipose-specific ablation of LSD1 in mice attenuated the butyrate-mediated induction of thermogenesis and energy expenditure. Notably, our results showed that butyrate directly increased the expression of LSD1 and UCP1 as well as butyrate transporter monocarboxylate transporter 1 (MCT1) and catabolic enzyme acyl-CoA medium-chain synthetase 3 (ACSM3) in ex vivo cultured adipocytes. The inhibition of MCT1 blocked the effects of butyrate in adipocytes. Furthermore, the butyrate-mediated prevention of diet-induced obesity (DIO) through increased thermogenesis was attenuated in LSD1 aKO mice. Moreover, after gavaging HFD-fed mice with the dietary fiber inulin, a substrate of microbial fermentation that rapidly produces butyrate, thermogenesis in both BAT and scWAT was increased, and DIO was decreased; however, these beneficial metabolic effects were blocked in LSD1 aKO mice. CONCLUSIONS Together, our results indicate that the microbial metabolite butyrate regulates thermogenesis in BAT and scWAT through the activation of LSD1.

Abstract
The regeneration of the blood vessel system post spinal cord injury (SCI) is essential for the repair of neurological function. As a significant means to regulate gene expression, epigenetic regulation of angiogenesis in SCI is still largely unknown. Here, we found that Ubiquitously Transcribed tetratricopeptide repeat on chromosome X (UTX), the histone H3K27 demethylase, increased significantly in endothelial cells post SCI. Knockdown of UTX can promote the migration and tube formation of endothelial cells. The specific knockout of UTX in endothelial cells enhanced angiogenesis post SCI accompanied with improved neurological function. In addition, we found regulation of UTX expression can change the level of microRNA 24 (miR-24) in vitro. The physical binding of UTX to the promotor of miR-24 was indicated by chromatin immunoprecipitation (ChIP) assay. Meanwhile, methylation sequencing of endothelial cells demonstrated that UTX could significantly decrease the level of methylation in the miR-24 promotor. Furthermore, miR-24 significantly abolished the promoting effect of UTX deletion on angiogenesis in vitro and in vivo. Finally, we predicted the potential target mRNAs of miR-24 related to angiogenesis. We indicate that UTX deletion can epigenetically promote the vascular regeneration and functional recovery post SCI by forming a regulatory network with miR-24.

AR (androgen receptor) and PKM2 (pyruvate kinase M2) have key roles in these processes. We report in this study, KDM8/JMJD5, a histone lysine demethylase/dioxygnase, exhibits a novel property as a dual coactivator of AR and PKM2 and as such, it is a potent inducer of castration and therapy resistance. Previously, we showed that KDM8 is involved in the regulation of cell cycle and tumor metabolism in breast cancer cells. Its role in prostate cancer has not been explored. Here, we show that KDM8's oncogenic properties in prostate cancer come from its direct interaction (1) with AR to affect androgen response and (2) with PKM2 to regulate tumor metabolism. The interaction with AR leads to the elevated expression of androgen response genes in androgen-deprived conditions. They include ANCCA/ATAD2 and EZH2, which are directly targeted by KDM8 and involved in sustaining the survival of the cells under hormone-deprived conditions. Notably, in enzalutamide-resistant cells, the expressions of both KDM8 and EZH2 are further elevated, so are neuroendocrine markers. Consequently, EZH2 inhibitors or KDM8 knockdown both resensitize the cells toward enzalutamide. In the cytosol, KDM8 associates with PKM2, the gatekeeper of pyruvate flux and translocates PKM2 into the nucleus, where the KDM8/PKM2 complex serves as a coactivator of HIF-1α to upregulate glycolytic genes. Using shRNA knockdown, we validate KDM8's functions as a regulator for both androgen-responsive and metabolic genes. KDM8 thus presents itself as an ideal therapeutic target for metabolic adaptation and castration-resistance of prostate cancer cells.

Abstract
Anthocyanins are involved in several aspects of development and defence in poplar (Populus spp.). Although, over the past decades, significant progress has been made in uncovering these anthocyanin biosynthetic and regulatory mechanisms, the fundamental understanding of the epigenetic regulation in this pathway is still largely unclear. Here, we isolated a histone H3K9 demethylase gene JMJ25 from Populus and characterized its role in anthocyanin biosynthesis by genetic and biochemical approaches. JMJ25 was induced by continuous dark treatment. Overexpression of JMJ25 led to downregulated expression of anthocyanin biosynthetic genes in transgenic poplar, resulting in a significant reduction in anthocyanin content. ChIP-qPCR assays showed that JMJ25 could directly associate with MYB182 chromatin and dynamically demethylate at H3K9me2. Furthermore, JMJ25 also affected the DNA methylation levels of MYB182. By contrast, knockout of JMJ25 by CRISPR/Cas9 resulted in ectopic anthocyanin accumulation under dark condition and increased expression of anthocyanin biosynthetic genes. Our results support a model in which JMJ25 directly affects MYB182 expression by altering the histone methylation status of its chromatin and DNA methylation, resulting in repression of anthocyanin accumulation. This study uncovered an epigenetic mechanism that modulates anthocyanin biosynthesis in poplar.

Abstract
Epigenetic changes, including histone methylation, control T cell differentiation and memory formation, though the enzymes that mediate these processes are not clear. We show that UTX, a histone H3 lysine 27 (H3K27) demethylase, supports T follicular helper (Tfh) cell responses that are essential for B cell antibody generation and the resolution of chronic viral infections. Mice with a T cell-specific UTX deletion had fewer Tfh cells, reduced germinal center responses, lacked virus-specific immunoglobulin G (IgG), and were unable to resolve chronic lymphocytic choriomeningitis virus infections. UTX-deficient T cells showed decreased expression of interleukin-6 receptor-α and other Tfh cell-related genes that were associated with increased H3K27 methylation. Additionally, Turner Syndrome subjects, who are predisposed to chronic ear infections, had reduced UTX expression in immune cells and decreased circulating CD4(+) CXCR5(+) T cell frequency. Thus, we identify a critical link between UTX in T cells and immunity to infection.

Abstract
Cancer initiating cells (CICs) are responsible for the unrestrained cell growth and chemoresistance of malignant tumors. Histone demethylation has been shown to be crucial for self-renewal/differentiation of stem cells, but it remains elusive whether lysine-specific demethylase 1 (LSD1) regulates the stemness properties of CICs. Here we report that the abundant expression of leucine-rich repeat-containing G-protein-coupled receptor 5 (Lgr5) is associated with the progression of hepatocellular carcinoma (HCC). Lgr5(+) HCC cells behave similarly to CICs and are highly tumorigenic and resistant to chemotherapeutic agents. Importantly, Lgr5(+) cells express higher levels of LSD1, which in turn regulates Lgr5 expression and promotes the self-renewal and drug resistance of Lgr5(+) CICs. Mechanistically, LSD1 promotes β-catenin activation by inhibiting the expression of several suppressors of β-catenin signaling, especially Prickle1 and APC in Lgr5(+) CICs, by directly regulating the levels of mono- and di-methylation of histone H3 lysine-4 at the promoters of these genes. Furthermore, LSD1-associated activation of the β-catenin signaling is essential for maintaining the activity of Lgr5(+) CICs. Together, our findings unravel the LSD1/Prickle1/APC/β-catenin signaling axis as a novel molecular circuit regulating the stemness and chemoresistance of hepatic Lgr5(+) CICs and provide potential targets to improve chemotherapeutic efficacies against HCC.

Abstract
Dynamic packaging of DNA into strings of nucleosomes is a major mechanism whereby eukaryotic cells regulate gene expression. Intricate control of nucleosomal structure and assembly governs access of RNA polymerase II to DNA and consequent RNA synthesis. As part of this, post-translational modifications of histone proteins are central to the regulation of chromatin structure, playing vital roles in regulating the activation and repression of gene transcription. In the heart, dynamic homeostasis of histone modification-driven by the actions of modifiers and recruitment of downstream effectors-is a fundamental regulator of the transcriptional reprogramming that occurs in the setting of disease-related stress. Here, we examine the growing evidence for histone modification as a key mechanism governing pathological growth and remodeling of the myocardium.

Abstract
The hallmark of most cancer cells is the metabolic shift from mitochondrial to glycolytic metabolism for adapting to the surrounding environment. Although epigenetic modification is intimately linked to cancer, the molecular mechanism, by which epigenetic factors regulate cancer metabolism, is poorly understood. Here, we show that lysine-specific demethylase-1 (LSD1, KDM1A) has an essential role in maintaining the metabolic shift in human hepatocellular carcinoma cells. Inhibition of LSD1 reduced glucose uptake and glycolytic activity, with a concurrent activation of mitochondrial respiration. These metabolic changes coexisted with the inactivation of the hypoxia-inducible factor HIF1α, resulting in a decreased expression of GLUT1 and glycolytic enzymes. In contrast, during LSD1 inhibition, a set of mitochondrial metabolism genes was activated with the concomitant increase of methylated histone H3 at lysine 4 in the promoter regions. Consistently, both LSD1 and GLUT1 were significantly overexpressed in carcinoma tissues. These findings demonstrate the epigenetic plasticity of cancer cell metabolism, which involves an LSD1-mediated mechanism.

Abstract
The histone demethylase LSD1 (lysine specific demethylase 1) plays an important role in the epigenetic regulation of gene transcription. Our study investigated the role of LSD1 in pancreatic cancer and demonstrated that LSD1 was significantly up-regulated in pancreatic cancer patient tissue samples, and elevated LSD1 protein levels positively correlated with overall survival of pancreatic cancer patients. Using in vitro and in vivo models, we demonstrated that knock-down of LSD1 repressed proliferation and tumorigenicity of pancreatic cancer cells. Mechanistically, our study demonstrated that LSD1 synergized with HIF1α (hypoxia inducible factor-1α) in maintaining glycolytic process, which fueled pancreatic cancer uncontrolled proliferation.

Abstract
Histone methylation is a dynamic and reversible process proposed to directly impact on stem cell fate. The Jumonji (JmjC) domain-containing family of demethylases comprises 27 members that target mono-, di-, and trimethylated lysine residues of histone (or nonhistone) proteins. To evaluate their role in regulation of hematopoietic stem cell (HSC) behavior, we performed an in vivo RNAi-based functional screen and demonstrated that Jarid1b and Jhdm1f play opposing roles in regulation of HSC activity. Decrease in Jarid1b levels correlated with an in vitro expansion of HSCs with preserved long-term in vivo lymphomyeloid differentiation potential. Through RNA sequencing analysis, Jarid1b knockdown was associated with increased expression levels of several HSC regulators (Hoxa7, Hoxa9, Hoxa10, Hes1, Gata2) and reduced levels of differentiation-associated genes. shRNA against Jhdmlf, in contrast, impaired hematopoietic reconstitution of bone marrow cells. Together, our studies identified Jarid1b as a negative regulator of HSC activity and Jhdmlf as a positive regulator of HSC activity.

Abstract
Here, we describe that lysine-specific demethylase 1 (Lsd1/KDM1a), which demethylates histone H3 on Lys4 or Lys9 (H3K4/K9), is an indispensible epigenetic governor of hematopoietic differentiation. Integrative genomic analysis, combining global occupancy of Lsd1, genome-wide analysis of its substrates H3K4 monomethylation and dimethylation, and gene expression profiling, reveals that Lsd1 represses hematopoietic stem and progenitor cell (HSPC) gene expression programs during hematopoietic differentiation. We found that Lsd1 acts at transcription start sites, as well as enhancer regions. Loss of Lsd1 was associated with increased H3K4me1 and H3K4me2 methylation on HSPC genes and gene derepression. Failure to fully silence HSPC genes compromised differentiation of hematopoietic stem cells as well as mature blood cell lineages. Collectively, our data indicate that Lsd1-mediated concurrent repression of enhancer and promoter activity of stem and progenitor cell genes is a pivotal epigenetic mechanism required for proper hematopoietic maturation.

Abstract
Using a mouse model of human MLL-AF9 leukemia, we identified the lysine-specific demethylase KDM1A (LSD1 or AOF2) as an essential regulator of leukemia stem cell (LSC) potential. KDM1A acts at genomic loci bound by MLL-AF9 to sustain expression of the associated oncogenic program, thus preventing differentiation and apoptosis. In vitro and in vivo pharmacologic targeting of KDM1A using tranylcypromine analogs active in the nanomolar range phenocopied Kdm1a knockdown in both murine and primary human AML cells exhibiting MLL translocations. By contrast, the clonogenic and repopulating potential of normal hematopoietic stem and progenitor cells was spared. Our data establish KDM1A as a key effector of the differentiation block in MLL leukemia, which may be selectively targeted to therapeutic effect.

Abstract
Many studies have demonstrated that covalent histone modifications are dynamically regulated to cause both chemical and physical changes to the chromatin template. Such changes in the chromatin template lead to biologically significant consequences, including differential gene expression. Histone lysine methylation, in particular, has been shown to correlate with gene expression both positively and negatively, depending on the specific site and degree (i.e., mono-, di-, or tri-) of methylation within the histone sequence. Although genetic alterations in the proteins that establish, or "write," methyl modifications and their effect in various human pathologies have been documented, connections between the misregulation of proteins that remove, or "erase," histone methylation and disease have emerged more recently. Here we discuss three mechanisms through which histone methylation can be removed from the chromatin template. We describe how these "erasure" mechanisms are linked to pathways that are known to be misregulated in diseases, such as cancer. We further describe how errors in the removal of histone methylation can and do lead to human pathologies, both directly and indirectly.

Abstract
Cancer is traditionally viewed as a primarily genetic disorder. However, it is now increasingly apparent that epigenetic abnormalities play a fundamental role in cancer development. Aberrant expression of histone-modifying enzymes has been implicated in the course of tumor initiation and progression. The discovery of a large number of histone demethylases suggests an important role for dynamic regulation of histone methylation in biological processes. The observation that overexpression, amplification or mutations of several histone demethylases have been found in many types of tumors, raise the possibility of using these enzymes as diagnostic tools as well as pave a way for the discovery of novel therapeutic targets and treatment modalities. Here, we review the current knowledge of the potential role of H3K4, H3K9 and H3K27 histone demethylases in tumorigenesis.
