<p><small><strong> Figure 1. ChIP results obtained with the Diagenode antibody directed against H3K79me1</strong><br /> ChIP assays were performed using human HeLa cells, the Diagenode antibody against H3K79me1 (Cat.

A titration consisting of 1, 2, 5 and 10 μg of antibody per ChIP experiment was analyzed. IgG (2 μg/IP) was used as a negative IP control. Quantitative PCR was performed with primers specific for a region 1 kb upstream of the promoter and the coding region of the active GAPDH gene, used as positive controls, and for exon 2 of the inactive myoglobin (MB) gene and the Sat2 satellite repeat, used as negative controls.

<p><small><strong> Figure 1. ChIP results obtained with the Diagenode antibody directed against H3K79me1</strong><br /> ChIP assays were performed using human HeLa cells, the Diagenode antibody against H3K79me1 (Cat. No. pAb-082-050) and optimized PCR primer pairs for qPCR. ChIP was performed with the “iDeal ChIP-seq” kit (cat. No. AB-001-0024), using sheared chromatin from 1 million cells. A titration consisting of 1, 2, 5 and 10 μg of antibody per ChIP experiment was analyzed. IgG (2 μg/IP) was used as a negative IP control. Quantitative PCR was performed with primers specific for a region 1 kb upstream of the promoter and the coding region of the active GAPDH gene, used as positive controls, and for exon 2 of the inactive myoglobin (MB) gene and the Sat2 satellite repeat, used as negative controls. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis). </small></p>

They are rich in the amino acids arginine and lysine and have been greatly conserved during evolution. Histones pack the DNA into tight masses of chromatin. Two core histones of each class H2A, H2B, H3 and H4 assemble and are wrapped by 146 base pairs of DNA to form one octameric nucleosome. Histone tails undergo numerous post-translational modifications, which either directly or indirectly alter chromatin structure to facilitate transcriptional activation or repression or other nuclear processes. In addition to the genetic code, combinations of the different histone modifications reveal the so-called “histone code”.

'description' => '<p>Histones are the main protein components of chromatin involved in the compaction of DNA into nucleosomes, the basic units of chromatin. A <strong>nucleosome</strong> consists of one pair of each of the core histones (<strong>H2A</strong>, <strong>H2B</strong>, <strong>H3</strong> and <strong>H4</strong>) forming an octameric structure wrapped by 146 base pairs of DNA. The different nucleosomes are linked by the linker histone<strong> H1, </strong>allowing for further condensation of chromatin.</p>
<p>The core histones have a globular structure with large unstructured N-terminal tails protruding from the nucleosome. They can undergo to multiple post-translational modifications (PTM), mainly at the N-terminal tails. These <strong>post-translational modifications </strong>include methylation, acetylation, phosphorylation, ubiquitinylation, citrullination, sumoylation, deamination and crotonylation. The most well characterized PTMs are <strong>methylation,</strong> <strong>acetylation and phosphorylation</strong>. Histone methylation occurs mainly on lysine (K) residues, which can be mono-, di- or tri-methylated, and on arginines (R), which can be mono-methylated and symmetrically or asymmetrically di-methylated. Histone acetylation occurs on lysines and histone phosphorylation mainly on serines (S), threonines (T) and tyrosines (Y).</p>
<p>The PTMs of the different residues are involved in numerous processes such as DNA repair, DNA replication and chromosome condensation. They influence the chromatin organization and can be positively or negatively associated with gene expression. Trimethylation of H3K4, H3K36 and H3K79, and lysine acetylation generally result in an open chromatin configuration (figure below) and are therefore associated with <strong>euchromatin</strong> and gene activation. Trimethylation of H3K9, K3K27 and H4K20, on the other hand, is enriched in <strong>heterochromatin </strong>and associated with gene silencing. The combination of different histone modifications is called the "<strong>histone code</strong>”, analogous to the genetic code.</p>

<p><br />Chromatin immunoprecipitation (<b>ChIP</b>) is a technique to study the associations of proteins with the specific genomic regions in intact cells. One of the most important steps of this protocol is the immunoprecipitation of targeted protein using the antibody specifically recognizing it. The quality of antibodies used in ChIP is essential for the success of the experiment. Diagenode offers extensively validated ChIP-grade antibodies, confirmed for their specificity, and high level of performance in ChIP. Each batch is validated, and batch-specific data are available on the website.</p>

'description' => '<p>50 years ago, Vincent Allfrey and colleagues discovered that lymphocyte activation triggers massive acetylation of chromatin. However, the molecular mechanisms driving epigenetic accessibility are still unknown. We here show that stimulated lymphocytes decondense chromatin by three differentially regulated steps. First, chromatin is repositioned away from the nuclear periphery in response to global acetylation. Second, histone nanodomain clusters decompact into mononucleosome fibers through a mechanism that requires Myc and continual energy input. Single-molecule imaging shows that this step lowers transcription factor residence time and non-specific collisions during sampling for DNA targets. Third, chromatin interactions shift from long range to predominantly short range, and CTCF-mediated loops and contact domains double in numbers. This architectural change facilitates cognate promoter-enhancer contacts and also requires Myc and continual ATP production. Our results thus define the nature and transcriptional impact of chromatin decondensation and reveal an unexpected role for Myc in the establishment of nuclear topology in mammalian cells.</p>',

'description' => 'Telomeres hide (or ‘cap’) chromosome ends from DNA-damage surveillance mechanisms that arrest the cell cycle and promote repair, but the checkpoint status of telomeres is not well understood. Here we characterize the response in Saccharomyces cerevisiae to DNA double-strand breaks (DSBs) flanked by varying amounts of telomeric repeat sequences (TG1–3). We show that even short arrays of TG1–3 repeats do not induce G2/M arrest. Both Rif1 1 and Rif2 are required for capping at short, rapidly elongating ends, yet are largely dispensable for protection of longer telomeric arrays. Rif1 1 and Rif2 act through parallel pathways to block accumulation of both RPA and Rad24, activators of checkpoint kinase Mec1 1 (ATR). Finally, we show that Rif function is correlated with an ‘anticheckpoint’ effect, in which checkpoint recovery at an adjacent unprotected end is stimulated, and we provide insight into the molecular mechanism of this phenomenon.',

'description' => 'Oct4, Nanog and Sox2 constitute a core of transcription factors controlling pluripotency. Differentiation and reprogramming studies have unraveled a few epigenetic modifications associated in relation to the expression state of OCT4, NANOG and SOX2. There is, however, no comprehensive map of chromatin states on these genes in human primary cells at different stages of differentiation. We report here a profile of DNA methylation and of 10 histone modifications on regulatory regions of OCT4, NANOG and SOX2 in embryonal carcinoma cells, mesenchymal stem cells and fibroblasts. Bisulfite sequencing reveals correlation between promoter CpG methylation and repression of OCT4, but not NANOG or SOX2, suggesting distinct repression mechanisms. Whereas none of these genes, even when inactive, harbor repressive trimethylated H3K9, CpG hypomethylated NANOG and SOX2, but not CpG methylated OCT4, are enriched in repressive H3K27me3. H3K79me1 and H3K79me3 tend to parallel each other and are linked to repression. Moreover, we highlight an inverse relationship between H3K27me3 occupancy on promoters and H3K36me3 occupancy on coding regions of OCT4, NANOG and SOX2, suggesting a cross-talk between K27 and K36 methylation. Establishment of distinct repression mechanisms for pluripotency-associated genes may constitute a safeguard system to prevent promiscuous reactivation during development or differentiation.',

'description' => 'Oct4, Nanog and Sox2 constitute a core of transcription factors controlling pluripotency. Differentiation and reprogramming studies have unraveled a few epigenetic modifications associated in relation to the expression state of OCT4, NANOG and SOX2. There is, however, no comprehensive map of chromatin states on these genes in human primary cells at different stages of differentiation. We report here a profile of DNA methylation and of 10 histone modifications on regulatory regions of OCT4, NANOG and SOX2 in embryonal carcinoma cells, mesenchymal stem cells and fibroblasts. Bisulfite sequencing reveals correlation between promoter CpG methylation and repression of OCT4, but not NANOG or SOX2, suggesting distinct repression mechanisms. Whereas none of these genes, even when inactive, harbor repressive trimethylated H3K9, CpG hypomethylated NANOG and SOX2, but not CpG methylated OCT4, are enriched in repressive H3K27me3. H3K79me1 and H3K79me3 tend to parallel each other and are linked to repression. Moreover, we highlight an inverse relationship between H3K27me3 occupancy on promoters and H3K36me3 occupancy on coding regions of OCT4, NANOG and SOX2, suggesting a cross-talk between K27 and K36 methylation. Establishment of distinct repression mechanisms for pluripotency-associated genes may constitute a safeguard system to prevent promiscuous reactivation during development or differentiation.',

A titration consisting of 1, 2, 5 and 10 μg of antibody per ChIP experiment was analyzed. IgG (2 μg/IP) was used as a negative IP control. Quantitative PCR was performed with primers specific for a region 1 kb upstream of the promoter and the coding region of the active GAPDH gene, used as positive controls, and for exon 2 of the inactive myoglobin (MB) gene and the Sat2 satellite repeat, used as negative controls. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis). </small></p>

'description' => '<p>Histones are the main protein components of chromatin involved in the compaction of DNA into nucleosomes, the basic units of chromatin. A <strong>nucleosome</strong> consists of one pair of each of the core histones (<strong>H2A</strong>, <strong>H2B</strong>, <strong>H3</strong> and <strong>H4</strong>) forming an octameric structure wrapped by 146 base pairs of DNA. The different nucleosomes are linked by the linker histone<strong> H1, </strong>allowing for further condensation of chromatin.</p>
<p>The core histones have a globular structure with large unstructured N-terminal tails protruding from the nucleosome. They can undergo to multiple post-translational modifications (PTM), mainly at the N-terminal tails. These <strong>post-translational modifications </strong>include methylation, acetylation, phosphorylation, ubiquitinylation, citrullination, sumoylation, deamination and crotonylation. The most well characterized PTMs are <strong>methylation,</strong> <strong>acetylation and phosphorylation</strong>. Histone methylation occurs mainly on lysine (K) residues, which can be mono-, di- or tri-methylated, and on arginines (R), which can be mono-methylated and symmetrically or asymmetrically di-methylated. Histone acetylation occurs on lysines and histone phosphorylation mainly on serines (S), threonines (T) and tyrosines (Y).</p>
<p>The PTMs of the different residues are involved in numerous processes such as DNA repair, DNA replication and chromosome condensation. They influence the chromatin organization and can be positively or negatively associated with gene expression. Trimethylation of H3K4, H3K36 and H3K79, and lysine acetylation generally result in an open chromatin configuration (figure below) and are therefore associated with <strong>euchromatin</strong> and gene activation. Trimethylation of H3K9, K3K27 and H4K20, on the other hand, is enriched in <strong>heterochromatin </strong>and associated with gene silencing. The combination of different histone modifications is called the "<strong>histone code</strong>”, analogous to the genetic code.</p>

<p><small> ChIP was performed on sheared chromatin from 100,000 K562 cells using iDeal ChIP-seq kit for Histones (cat. No. C01010051) with 1 µg of the Diagenode antibodies against H3K27me3 (cat. No. C15410195) and H3K4me3 (cat. No. C15410003), and 0.5 µg of the antibody against H3K36me3 (cat. No. C15410192). The IP'd DNA was subsequently analysed on an Illumina Genome Analyzer. Library preparation, cluster generation and sequencing were performed according to the manufacturer's instructions. The 36 bp tags were aligned to the human genome using the ELAND algorithm. The figure shows the signal distribution along the complete sequence of human chromosome 3, a zoomin to a 10 Mb region and a further zoomin to a 1.5 Mb region. </small></p>

<p><br />Chromatin immunoprecipitation (<b>ChIP</b>) is a technique to study the associations of proteins with the specific genomic regions in intact cells. One of the most important steps of this protocol is the immunoprecipitation of targeted protein using the antibody specifically recognizing it. The quality of antibodies used in ChIP is essential for the success of the experiment. Diagenode offers extensively validated ChIP-grade antibodies, confirmed for their specificity, and high level of performance in ChIP. Each batch is validated, and batch-specific data are available on the website.</p>

'description' => '<p>50 years ago, Vincent Allfrey and colleagues discovered that lymphocyte activation triggers massive acetylation of chromatin. However, the molecular mechanisms driving epigenetic accessibility are still unknown. We here show that stimulated lymphocytes decondense chromatin by three differentially regulated steps. First, chromatin is repositioned away from the nuclear periphery in response to global acetylation. Second, histone nanodomain clusters decompact into mononucleosome fibers through a mechanism that requires Myc and continual energy input. Single-molecule imaging shows that this step lowers transcription factor residence time and non-specific collisions during sampling for DNA targets. Third, chromatin interactions shift from long range to predominantly short range, and CTCF-mediated loops and contact domains double in numbers. This architectural change facilitates cognate promoter-enhancer contacts and also requires Myc and continual ATP production. Our results thus define the nature and transcriptional impact of chromatin decondensation and reveal an unexpected role for Myc in the establishment of nuclear topology in mammalian cells.</p>',

'description' => 'Telomeres hide (or ‘cap’) chromosome ends from DNA-damage surveillance mechanisms that arrest the cell cycle and promote repair, but the checkpoint status of telomeres is not well understood. Here we characterize the response in Saccharomyces cerevisiae to DNA double-strand breaks (DSBs) flanked by varying amounts of telomeric repeat sequences (TG1–3). We show that even short arrays of TG1–3 repeats do not induce G2/M arrest. Both Rif1 1 and Rif2 are required for capping at short, rapidly elongating ends, yet are largely dispensable for protection of longer telomeric arrays. Rif1 1 and Rif2 act through parallel pathways to block accumulation of both RPA and Rad24, activators of checkpoint kinase Mec1 1 (ATR). Finally, we show that Rif function is correlated with an ‘anticheckpoint’ effect, in which checkpoint recovery at an adjacent unprotected end is stimulated, and we provide insight into the molecular mechanism of this phenomenon.',

'description' => 'Oct4, Nanog and Sox2 constitute a core of transcription factors controlling pluripotency. Differentiation and reprogramming studies have unraveled a few epigenetic modifications associated in relation to the expression state of OCT4, NANOG and SOX2. There is, however, no comprehensive map of chromatin states on these genes in human primary cells at different stages of differentiation. We report here a profile of DNA methylation and of 10 histone modifications on regulatory regions of OCT4, NANOG and SOX2 in embryonal carcinoma cells, mesenchymal stem cells and fibroblasts. Bisulfite sequencing reveals correlation between promoter CpG methylation and repression of OCT4, but not NANOG or SOX2, suggesting distinct repression mechanisms. Whereas none of these genes, even when inactive, harbor repressive trimethylated H3K9, CpG hypomethylated NANOG and SOX2, but not CpG methylated OCT4, are enriched in repressive H3K27me3. H3K79me1 and H3K79me3 tend to parallel each other and are linked to repression. Moreover, we highlight an inverse relationship between H3K27me3 occupancy on promoters and H3K36me3 occupancy on coding regions of OCT4, NANOG and SOX2, suggesting a cross-talk between K27 and K36 methylation. Establishment of distinct repression mechanisms for pluripotency-associated genes may constitute a safeguard system to prevent promiscuous reactivation during development or differentiation.',

'description' => 'Oct4, Nanog and Sox2 constitute a core of transcription factors controlling pluripotency. Differentiation and reprogramming studies have unraveled a few epigenetic modifications associated in relation to the expression state of OCT4, NANOG and SOX2. There is, however, no comprehensive map of chromatin states on these genes in human primary cells at different stages of differentiation. We report here a profile of DNA methylation and of 10 histone modifications on regulatory regions of OCT4, NANOG and SOX2 in embryonal carcinoma cells, mesenchymal stem cells and fibroblasts. Bisulfite sequencing reveals correlation between promoter CpG methylation and repression of OCT4, but not NANOG or SOX2, suggesting distinct repression mechanisms. Whereas none of these genes, even when inactive, harbor repressive trimethylated H3K9, CpG hypomethylated NANOG and SOX2, but not CpG methylated OCT4, are enriched in repressive H3K27me3. H3K79me1 and H3K79me3 tend to parallel each other and are linked to repression. Moreover, we highlight an inverse relationship between H3K27me3 occupancy on promoters and H3K36me3 occupancy on coding regions of OCT4, NANOG and SOX2, suggesting a cross-talk between K27 and K36 methylation. Establishment of distinct repression mechanisms for pluripotency-associated genes may constitute a safeguard system to prevent promiscuous reactivation during development or differentiation.',

'description' => '<p>Histones are the main protein components of chromatin involved in the compaction of DNA into nucleosomes, the basic units of chromatin. A <strong>nucleosome</strong> consists of one pair of each of the core histones (<strong>H2A</strong>, <strong>H2B</strong>, <strong>H3</strong> and <strong>H4</strong>) forming an octameric structure wrapped by 146 base pairs of DNA. The different nucleosomes are linked by the linker histone<strong> H1, </strong>allowing for further condensation of chromatin.</p>
<p>The core histones have a globular structure with large unstructured N-terminal tails protruding from the nucleosome. They can undergo to multiple post-translational modifications (PTM), mainly at the N-terminal tails. These <strong>post-translational modifications </strong>include methylation, acetylation, phosphorylation, ubiquitinylation, citrullination, sumoylation, deamination and crotonylation. The most well characterized PTMs are <strong>methylation,</strong> <strong>acetylation and phosphorylation</strong>. Histone methylation occurs mainly on lysine (K) residues, which can be mono-, di- or tri-methylated, and on arginines (R), which can be mono-methylated and symmetrically or asymmetrically di-methylated. Histone acetylation occurs on lysines and histone phosphorylation mainly on serines (S), threonines (T) and tyrosines (Y).</p>
<p>The PTMs of the different residues are involved in numerous processes such as DNA repair, DNA replication and chromosome condensation. They influence the chromatin organization and can be positively or negatively associated with gene expression. Trimethylation of H3K4, H3K36 and H3K79, and lysine acetylation generally result in an open chromatin configuration (figure below) and are therefore associated with <strong>euchromatin</strong> and gene activation. Trimethylation of H3K9, K3K27 and H4K20, on the other hand, is enriched in <strong>heterochromatin </strong>and associated with gene silencing. The combination of different histone modifications is called the "<strong>histone code</strong>”, analogous to the genetic code.</p>

'description' => '<p>50 years ago, Vincent Allfrey and colleagues discovered that lymphocyte activation triggers massive acetylation of chromatin. However, the molecular mechanisms driving epigenetic accessibility are still unknown. We here show that stimulated lymphocytes decondense chromatin by three differentially regulated steps. First, chromatin is repositioned away from the nuclear periphery in response to global acetylation. Second, histone nanodomain clusters decompact into mononucleosome fibers through a mechanism that requires Myc and continual energy input. Single-molecule imaging shows that this step lowers transcription factor residence time and non-specific collisions during sampling for DNA targets. Third, chromatin interactions shift from long range to predominantly short range, and CTCF-mediated loops and contact domains double in numbers. This architectural change facilitates cognate promoter-enhancer contacts and also requires Myc and continual ATP production. Our results thus define the nature and transcriptional impact of chromatin decondensation and reveal an unexpected role for Myc in the establishment of nuclear topology in mammalian cells.</p>',

Here we characterize the response in Saccharomyces cerevisiae to DNA double-strand breaks (DSBs) flanked by varying amounts of telomeric repeat sequences (TG1–3). We show that even short arrays of TG1–3 repeats do not induce G2/M arrest. Both Rif1 1 and Rif2 are required for capping at short, rapidly elongating ends, yet are largely dispensable for protection of longer telomeric arrays. Rif1 1 and Rif2 act through parallel pathways to block accumulation of both RPA and Rad24, activators of checkpoint kinase Mec1 1 (ATR). Finally, we show that Rif function is correlated with an ‘anticheckpoint’ effect, in which checkpoint recovery at an adjacent unprotected end is stimulated, and we provide insight into the molecular mechanism of this phenomenon.',

'description' => 'Oct4, Nanog and Sox2 constitute a core of transcription factors controlling pluripotency. Differentiation and reprogramming studies have unraveled a few epigenetic modifications associated in relation to the expression state of OCT4, NANOG and SOX2. There is, however, no comprehensive map of chromatin states on these genes in human primary cells at different stages of differentiation. We report here a profile of DNA methylation and of 10 histone modifications on regulatory regions of OCT4, NANOG and SOX2 in embryonal carcinoma cells, mesenchymal stem cells and fibroblasts. Bisulfite sequencing reveals correlation between promoter CpG methylation and repression of OCT4, but not NANOG or SOX2, suggesting distinct repression mechanisms. Whereas none of these genes, even when inactive, harbor repressive trimethylated H3K9, CpG hypomethylated NANOG and SOX2, but not CpG methylated OCT4, are enriched in repressive H3K27me3. H3K79me1 and H3K79me3 tend to parallel each other and are linked to repression. Moreover, we highlight an inverse relationship between H3K27me3 occupancy on promoters and H3K36me3 occupancy on coding regions of OCT4, NANOG and SOX2, suggesting a cross-talk between K27 and K36 methylation. Establishment of distinct repression mechanisms for pluripotency-associated genes may constitute a safeguard system to prevent promiscuous reactivation during development or differentiation.',

'description' => 'Oct4, Nanog and Sox2 constitute a core of transcription factors controlling pluripotency. Differentiation and reprogramming studies have unraveled a few epigenetic modifications associated in relation to the expression state of OCT4, NANOG and SOX2. There is, however, no comprehensive map of chromatin states on these genes in human primary cells at different stages of differentiation. We report here a profile of DNA methylation and of 10 histone modifications on regulatory regions of OCT4, NANOG and SOX2 in embryonal carcinoma cells, mesenchymal stem cells and fibroblasts. Bisulfite sequencing reveals correlation between promoter CpG methylation and repression of OCT4, but not NANOG or SOX2, suggesting distinct repression mechanisms. Whereas none of these genes, even when inactive, harbor repressive trimethylated H3K9, CpG hypomethylated NANOG and SOX2, but not CpG methylated OCT4, are enriched in repressive H3K27me3. H3K79me1 and H3K79me3 tend to parallel each other and are linked to repression. Moreover, we highlight an inverse relationship between H3K27me3 occupancy on promoters and H3K36me3 occupancy on coding regions of OCT4, NANOG and SOX2, suggesting a cross-talk between K27 and K36 methylation. Establishment of distinct repression mechanisms for pluripotency-associated genes may constitute a safeguard system to prevent promiscuous reactivation during development or differentiation.',

<p><small><strong> Figure 1. ChIP results obtained with the Diagenode antibody directed against H3K79me1</strong><br /> ChIP assays were performed using human HeLa cells, the Diagenode antibody against H3K79me1 (Cat. No. pAb-082-050) and optimized PCR primer pairs for qPCR. ChIP was performed with the “iDeal ChIP-seq” kit (cat. No. AB-001-0024), using sheared chromatin from 1 million cells. A titration consisting of 1, 2, 5 and 10 μg of antibody per ChIP experiment was analyzed. IgG (2 μg/IP) was used as a negative IP control. Quantitative PCR was performed with primers specific for a region 1 kb upstream of the promoter and the coding region of the active GAPDH gene, used as positive controls, and for exon 2 of the inactive myoglobin (MB) gene and the Sat2 satellite repeat, used as negative controls. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis). </small></p>

A titration consisting of 1, 2, 5 and 10 μg of antibody per ChIP experiment was analyzed. IgG (2 μg/IP) was used as a negative IP control. Quantitative PCR was performed with primers specific for a region 1 kb upstream of the promoter and the coding region of the active GAPDH gene, used as positive controls, and for exon 2 of the inactive myoglobin (MB) gene and the Sat2 satellite repeat, used as negative controls.

'description' => '<p>Histones are the main protein components of chromatin involved in the compaction of DNA into nucleosomes, the basic units of chromatin. A <strong>nucleosome</strong> consists of one pair of each of the core histones (<strong>H2A</strong>, <strong>H2B</strong>, <strong>H3</strong> and <strong>H4</strong>) forming an octameric structure wrapped by 146 base pairs of DNA. The different nucleosomes are linked by the linker histone<strong> H1, </strong>allowing for further condensation of chromatin.</p>
<p>The core histones have a globular structure with large unstructured N-terminal tails protruding from the nucleosome. They can undergo to multiple post-translational modifications (PTM), mainly at the N-terminal tails. These <strong>post-translational modifications </strong>include methylation, acetylation, phosphorylation, ubiquitinylation, citrullination, sumoylation, deamination and crotonylation. The most well characterized PTMs are <strong>methylation,</strong> <strong>acetylation and phosphorylation</strong>. Histone methylation occurs mainly on lysine (K) residues, which can be mono-, di- or tri-methylated, and on arginines (R), which can be mono-methylated and symmetrically or asymmetrically di-methylated. Histone acetylation occurs on lysines and histone phosphorylation mainly on serines (S), threonines (T) and tyrosines (Y).</p>
<p>The PTMs of the different residues are involved in numerous processes such as DNA repair, DNA replication and chromosome condensation. They influence the chromatin organization and can be positively or negatively associated with gene expression. Trimethylation of H3K4, H3K36 and H3K79, and lysine acetylation generally result in an open chromatin configuration (figure below) and are therefore associated with <strong>euchromatin</strong> and gene activation. Trimethylation of H3K9, K3K27 and H4K20, on the other hand, is enriched in <strong>heterochromatin </strong>and associated with gene silencing. The combination of different histone modifications is called the "<strong>histone code</strong>”, analogous to the genetic code.</p>

'description' => '<p>50 years ago, Vincent Allfrey and colleagues discovered that lymphocyte activation triggers massive acetylation of chromatin. However, the molecular mechanisms driving epigenetic accessibility are still unknown. We here show that stimulated lymphocytes decondense chromatin by three differentially regulated steps. First, chromatin is repositioned away from the nuclear periphery in response to global acetylation. Second, histone nanodomain clusters decompact into mononucleosome fibers through a mechanism that requires Myc and continual energy input. Single-molecule imaging shows that this step lowers transcription factor residence time and non-specific collisions during sampling for DNA targets. Third, chromatin interactions shift from long range to predominantly short range, and CTCF-mediated loops and contact domains double in numbers. This architectural change facilitates cognate promoter-enhancer contacts and also requires Myc and continual ATP production. Our results thus define the nature and transcriptional impact of chromatin decondensation and reveal an unexpected role for Myc in the establishment of nuclear topology in mammalian cells.</p>',

Here we characterize the response in Saccharomyces cerevisiae to DNA double-strand breaks (DSBs) flanked by varying amounts of telomeric repeat sequences (TG1–3). We show that even short arrays of TG1–3 repeats do not induce G2/M arrest. Both Rif1 1 and Rif2 are required for capping at short, rapidly elongating ends, yet are largely dispensable for protection of longer telomeric arrays. Rif1 1 and Rif2 act through parallel pathways to block accumulation of both RPA and Rad24, activators of checkpoint kinase Mec1 1 (ATR). Finally, we show that Rif function is correlated with an ‘anticheckpoint’ effect, in which checkpoint recovery at an adjacent unprotected end is stimulated, and we provide insight into the molecular mechanism of this phenomenon.',

Differentiation and reprogramming studies have unraveled a few epigenetic modifications associated in relation to the expression state of OCT4, NANOG and SOX2. There is, however, no comprehensive map of chromatin states on these genes in human primary cells at different stages of differentiation. We report here a profile of DNA methylation and of 10 histone modifications on regulatory regions of OCT4, NANOG and SOX2 in embryonal carcinoma cells, mesenchymal stem cells and fibroblasts. Bisulfite sequencing reveals correlation between promoter CpG methylation and repression of OCT4, but not NANOG or SOX2, suggesting distinct repression mechanisms. Whereas none of these genes, even when inactive, harbor repressive trimethylated H3K9, CpG hypomethylated NANOG and SOX2, but not CpG methylated OCT4, are enriched in repressive H3K27me3. H3K79me1 and H3K79me3 tend to parallel each other and are linked to repression. Moreover, we highlight an inverse relationship between H3K27me3 occupancy on promoters and H3K36me3 occupancy on coding regions of OCT4, NANOG and SOX2, suggesting a cross-talk between K27 and K36 methylation. Establishment of distinct repression mechanisms for pluripotency-associated genes may constitute a safeguard system to prevent promiscuous reactivation during development or differentiation.',

'description' => 'Oct4, Nanog and Sox2 constitute a core of transcription factors controlling pluripotency. Differentiation and reprogramming studies have unraveled a few epigenetic modifications associated in relation to the expression state of OCT4, NANOG and SOX2. There is, however, no comprehensive map of chromatin states on these genes in human primary cells at different stages of differentiation. We report here a profile of DNA methylation and of 10 histone modifications on regulatory regions of OCT4, NANOG and SOX2 in embryonal carcinoma cells, mesenchymal stem cells and fibroblasts. Bisulfite sequencing reveals correlation between promoter CpG methylation and repression of OCT4, but not NANOG or SOX2, suggesting distinct repression mechanisms. Whereas none of these genes, even when inactive, harbor repressive trimethylated H3K9, CpG hypomethylated NANOG and SOX2, but not CpG methylated OCT4, are enriched in repressive H3K27me3. H3K79me1 and H3K79me3 tend to parallel each other and are linked to repression. Moreover, we highlight an inverse relationship between H3K27me3 occupancy on promoters and H3K36me3 occupancy on coding regions of OCT4, NANOG and SOX2, suggesting a cross-talk between K27 and K36 methylation. Establishment of distinct repression mechanisms for pluripotency-associated genes may constitute a safeguard system to prevent promiscuous reactivation during development or differentiation.',
